### Introduction

Fhem is mainly used for home automation, but it is suitable for other tasks too, where notification, timers and logging plays an important role.
It supports different hardware devices to interface with certain protocols (e.g. FHZ1000 to interface FS20 and HMS, CM11 to access X10), and logical devices like FS20 or FHT to digest the messages for a certain device type using this protocol.
Fhem is modular. The different devices are represented through modules which implement certain functions (e.g. define, get, set). Even seemingly integral parts of fhem like triggers (notify) and timers (at) are implemented this way, giving the possibility to replace/extend this functionality.
Fhem is controlled through readable / ascii commands, which are specified in files (e.g. the configuration file), or issued over a TCP/IP connection, either directly in a telnet session, with a fhem.pl in client mode or from one of the web frontends.
When starting the server you have to specify a configuration file:

`fhem.pl ~/.fhem`

A minimal configuration file:

        attr global logfile /tmp/fhem.log
        attr global statefile /tmp/fhem.save
        attr global verbose 3
        attr global port 7072
        attr global modpath /usr/share/fhem
        define FHZ FHZ /dev/tts/USB0

        define lamp FS20 8765 01

For other configuration files see the examples subdirectory.
TCP/IP communication with fhem can either happen in a "session" (via telnet) or single client command (via fhem.pl). Example:

`telnet localhost 7072
<NL>` (This newline switches into "prompt" mode)`
<command>...
quit`

or

`fhem.pl 7072 "set lamp off"`

### Fhem command types

There are three types of commands: "fhem" commands (described in this document), shell commands (they must be enclosed in double quotes ") and perl expressions (enclosed in curly brackets {}). shell commands or perl expressions are needed for complex at or notify arguments, but can also issued as a "normal" command.
E.g. the following three commands all do the same when issued from a telnet prompt:

set lamp off
"fhem.pl 7072 "set lamp off""
{fhem("set lamp off")}

Shell commands will be executed in the background, perl expressions and fhem commands will be executed in the main "thread". In order to make perl expressions easier to write, some special functions and variables are available. See the section Perl special for a description. To trigger fhem commands from a shell script (this is the "other way round"), use the client form of fhem.pl (described above).
Multiple fhem commands are separated by semicolon (;). In order to use semicolon in perl code or shell programs, they have to be escaped by the double semicolon (;;). See the Notes section of the notify chapter on command parameters and escape rules.
E.g. the following first command switches Lamp1 off at 07:00 and Lamp2 immediately (at the point of definition), the second one switches both lamps off at 07:00.

define lampoff at 07:00 set Lamp1 off; set Lamp2 off
define lampoff at 07:00 set Lamp1 off;; set Lamp2 off

Commands can be either typed in plain, or read from a file (e.g. the configuration file at startup). The commands are either executed directly, or later if they are arguments to the at and notify fhem commands.
A line ending with \ will be concatenated with the next one, so long lines (e.g. multiple perl commands) can be split in multiple lines. Some web fronteds (e.g. webpgm2) make editing of multiline commands transparent for you (i.e. there is no need for \) .

### Device specification (devspec)

The commands attr, deleteattr, delete, get, list, set, setstate, trigger can take a more complex device specification as argument, which will be expanded to a list of devices. A device specification (short devspec) can be:

- a single device name. This is the most common case.
- a list of devices, separated by comma (,)
- a range of devices, separated by dash (-)
- a regular expression, if the the spec contains on e of the following characters: ^*[]$
- an attribute of the device, followed by an equal sign (=) and then a regexp for this attribute. As attribute you can specify either attributes set with the attr command or one of the "internal" attributes DEF, STATE and TYPE.

Example:

`set lamp1 on`
`set lamp1,lamp2,lamp3 on`
`set lamp[1-3] on`
`set lamp.* on`
`set lamp1-lamp3 on`
`set lamp1-lamp3,lamp3 on`
`set room=kitchen off`
`list disabled=`
`list TYPE=FS20`

Notes:

- first the spec is separated by komma, then the range or the regular expression operations are executed.
- if there is a device which exactly corresponds to the spec, then no special processing is done.
- the returned list can contain the same device more than once, so "set lamp1-lamp3,lamp3 on" switches lamp3 twice.
- for more complex structuring demands see the structure device.

### ?, help

`?`
`help`
Get a list of all commands and short description for each one

### attr

`attr <devspec> <attrname> [<value>]`
Set an attribute for a device defined by define. You can define your own attributes too to use them in other applications. Use "attr <name> ?" to get a list of possible attributes. See the Device specification section for details on <devspec>.
Attributes used by all devices:

- comment
  Add an arbitrary comment.
- room
  Filter/group devices. Recognized by web-pgm2 and web-pgm3. A device can appear in more than one room, in this case the rooms have to be specified komma separated.
  Devices in the room hidden will not appear in the web output, or set the FHEMWEB attribute to selectively disable rooms for certain FHEMWEB instances.
- showtime
  Used in the webfrontend pgm2 to show the time of last activity instead of the state in the summary view. Useful e.g. for FS20 PIRI devices.

Device specific attributes are documented in the corresponding device section.
Examples:

`attr global verbose 3`
`attr lamp room kitchen`
`attr lamp loglevel 6`

Notes:

- See deleteattr to delete attributes.

### setdefaultattr

`setdefaultattr [<attrname> [<value>]]`
Add a default attribute. Each device defined from now on will receive this attribute.
If no attrname is specified, then the default attribute list will be deleted.
Example to set the attribute "room kitchen" and "loglevel 4" to each of the lamps:

`setdefaultattr room kitchen`
`setdefaultattr loglevel 4`
`define lamp1 FS20 1234 11`
`define lamp2 FS20 1234 12`
`define lamp3 FS20 1234 13`
`setdefaultattr`

Notes:

- There is no way to delete a single default-attribute from the list

### define

`define <name> <type> <type-specific>`
Define a device. You need devices if you want to manipulate them (e.g. set on/off), and the logfile is also more readable if it contains e.g. "lamp off" instead of "Device 5673, Button 00, Code 00 (off)".
Use "define <name> ?" to get a list of possible types.
After definition, the global event "DEFINED" will be generated, see the notify section for details.
Each device takes different additional arguments at definition, see the corresponding device section for details.

### deleteattr

`deleteattr <devspec> [<attrname>]`
Delete either a single attribute (see the attr command) or all attributes for a device (if no <attrname> is defined). See the Device specification section for details on <devspec>.
Examples:

`deleteattr lamp follow-on-for-timer`
`deleteattr lamp`

### delete

`delete <devspec>`
Delete something created with the define command. See the Device specification section for details on <devspec>.
After deletion, the global event "DELETED" will be generated, see the notify section for details.
Examples:

`delete lamp`

### get

`get <devspec> <type-specific>`
Ask a value directly from the device, and wait for an answer. In general, you can get a list of possible parameters by

`get <device> ?`

See the Device specification section for details on <devspec>.
Each device has different get parameters, see the corresponding device section for details.

### getstate

`getstate <devspec>`
Output a short space seperated status for <devspec>. It is useful for monitoring the device in e.g. Cacti.
Examples:

`getstate lamp
state:1
getstate fl
ack:0 actuator:2 day-temp:21.5 desired-temp:22.5 [...] measured-temp:22.9 [...] ```

Note: to use this command copy the file contrib/getstate/99_getstate.pm into your FHEM directory.

### include

`include <filename>`
Read in the file, and process every line as a fhem command. Makes configuration files more modular and enables to reread them.

### inform

`inform {on|off|timer|raw} [regexp]`
If set to on, and a device state changes, send a notification to the current client. This command can be used by other programs/modules to receive a notification.
The option timer prepends a timerstamp to the line. Note: this command is a nice way to check which events are generated, to help you when creating notify or FileLog entries.

### jsonlist

`jsonlist [<devspec>|<typespec>|ROOMS]`
Returns an JSON tree of all definitions, all notify settings and all at entries if no parameter is given. Can also be called via HTTP by http://fhemhost:8083/fhem?cmd=jsonlist&XHR=1
Example:

      fhem> jsonlist

          },
        ],
        "totalResultsReturned": 235
      }

If specifying `<devspec>`, then a detailed status for `<devspec>` will be displayed, e.g.:

      fhem> jsonlist lamp1
      {
        "ResultSet": {
          "Results": {
            "ATTRIBUTES": {

            "READINGS": {
              "state": {
                "TIME": "2011-12-01 16:23:01",
                "VAL": "on"
              }
            },
            "STATE": "on",
            "TYPE": "FS20",
            "XMIT": "0b0b"
          }
        }
      }

If specifying `<typespec>`, then a list with the status for the defined `<typespec>` devices will be displayed, e.g.:

      fhem> jsonlist HMS
      {
        "ResultSet": "devices#HMS",
        "Results": [
          {
            "name": "KG.ga.WD.01",
            "state": "Water Detect: off"
          },
          {
            "name": "KG.hz.GD.01",
            "state": "Gas Detect: off"
          },
          {
            "name": "KG.k1.TF.01",
            "state": "T: 16.6  H: 51.2  Bat: ok"
          },
          {
            "name": "NN.xx.RM.xx",
            "state": "smoke_detect: off"
          }
        ],
        "totalResultsReturned": 4
      }

If specifying `ROOMS`, then a list with the defined rooms will be displayed, e.g.:

      fhem> jsonlist ROOMS
      {
        "ResultSet": "rooms",
        "Results": [
          "Bathroom",
          "Bedroom",
          "Children",
          "Diningroom",

          "Livingroom",
          "Office",
          "hidden"
        ],
        "totalResultsReturned": 15
      }

### updatefhem

`updatefhem [backup] [filename]`
Update the fhem modules and documentation from a nightly SVN chekout. For this purpose fhem contacts http://fhem.de/fhemupdate, compares the stored timestamps of the local files with the filelist on the server, and downloads the files changed on the server. For all downloaded modules a reload will be scheduled if the corresponding module is loaded.
If an explicit filename is given, then only this file will be downloaded.
Note: if the main program (fhem.pl) is changed, a manual restart of fhem will be necessary to apply the changes.
If backup is specified, then the old files are saved before overwriting them. They are copied to the folder given in global or as default to /tmp/FHEM_Backup. Please check if the fhem user has the rights to create a folder for backup.
Attributes

- backupdir
  A folder where updatefhem can store all files from modpath before executing the update. Please check if the fhem user has the rights to create this folder.
Note: this is a global attribute, e.g.

attr global backup /Volumes/BigHD

### CULflash

`CULflash <CUL-Name> <CUL-Version>`
Download the CUL firmware from a nightly SVN chekout and flash the hardware. Currently only the CUL is supported with its versions: CUL_V2, CUL_V2_HM, CUL_V3, CUL_V4.
Note: dfu-programmer has to be installed in the path, this is already the case with the Fritz!Box 7390 image from fhem.de
If the CUL is not yet flashed, then first define a CUL device (even if fhem won't be able to open the device), insert it with the button pressed (this will set the device into flash-mode), then issue the CULflash command.
Example:

`CULflash CUL CUL_V3`

### list

`list [devspec] [value]`
Output a list of all definitions, all notify settings and all at entries. This is one of the few commands which return a string in a normal case. See the Device specification section for details on <devspec>.
If value is specified, then output this property (like DEF, TYPE, etc) or reading (actuator, measured-temp) for all devices from the devspec.
Example:

      fhem> list

      Type list  for detailed info.

      Internal:
        global               (Internal)

      FHZ:
        FHZ                  (fhtbuf: 23)

      FS20:
        Btn4                 (on-old-for-timer)
        Roll1                (on)
        Stehlampe            (off)

      FHT:
        fl                   (measured-temp: 21.1 (Celsius))

      KS300:
        out1                 (T: 2.9  H: 74  W: 2.2  R: 8.2  IR: no)

      at:
        at_rollup            (Next: 07:00:00)

      notify:
        ntfy_btn4            (active)

      FileLog:
        avglog               (active)

If specifying `name`, then a detailed status for `name` will be displayed, e.g.:

      fhem> list fl

      Internals:
        CODE       5102
        DEF        5102
        NAME       fl
        NR         15
        STATE      measured-temp: 21.1 (Celsius)
        TYPE       FHT
        IODev      FHZ
      Attributes:
        room       Heizung
      Readings:
        2006-11-02 09:45:56   actuator        19%
        [...]

### modify

`modify <name> <type-dependent-options>`
Used to modify some definitions. Useful for changing some at or notify definitions. If specifying one argument to an at type definition, only the time part will be changed. In case of a notify type definition, only the regex part will be changed. All other values (state, attributes, etc) will remain intact.
Example:

`define lampon at 19:00 set lamp on`
`modify lampon *19:00`
`modify lampon 19:00 set lamp on-for-timer 16`

### quit

`quit`
If used in a TCP/IP session, terminate the client session.
If used in a script, terminate the parsing of the current script.
Example:

`quit`

### reload

`reload <module>`
Reload the given module from the module directory. It is a convenient way to test modules whithout restarting the program.
Example:

`reload 99_PRIV`

### rename

`rename <oldname> <newname>`
Rename a device from the <oldname> to <newname>, together with its attributes. The global event RENAMED will be generated, see the notify section for details.
Example:

`rename FHT_1234 fht.kitchen`

### rereadcfg

`rereadcfg`
Re-read the configuration file. Note: The statefile will be saved first, then the config file will be read (all devices will be initialized again), and at last the statefile will be reloaded. It triggers upon completion the global:REREADCFG event.
Example:

`rereadcfg`

### save

`save [<configfile>]`
Save first the statefile, then the configfile information. If a parameter is specified, it will be used instead the global configfile attribute.
Notes:

- save only writes out definitions and attributes, but no (set/get) commands which were previously part of the config file. If you need such commands after the initialization (e.g. FHTcode), you should trigger them via notify, when receiving the INITIALIZED event.

### set

`set <devspec> <type-specific>`
Set parameters of a device / send signals to a device. You can get a list of possible parameters by

`set <name> ?`

See the Device specification section for details on <devspec>. The set command returns only a value on error.
Each device has different set parameters, see the corresponding device section for details.

### setstate

`setstate <devspec> <value>`
Set the "STATE" for `<name>` as shown in paranthesis in the list command to `<value>` without sending any signals to the device itself. This command is also used in the statefile. See the Device specification section for details on <devspec>.
Examples:

setstate lamp on

Note:

- The statefile uses another version of this command, don't be surprised.

### shutdown

`shutdown`
Shut down the server (after saving the state information ). It triggers the global:SHUTDOWN event.
Example:

`shutdown`

### trigger

`trigger <devspec> <state>`
Trigger a notify definition. See the Device specification section for details on <devspec>.
Example:

`trigger btn3 on`

### sleep

`sleep <sec>`
Sleep for a given amount, millisecond accuracy.
Example:

`sleep 0.5`
`notify btn3 set lamp toggle;;sleep 0.5;;set lamp toggle`

Note: As the server is not multithreaded, everything is blocked for the given amount.

### xmllist

`xmllist`
Returns an XML tree of all definitions, all notify settings and all at entries. It is not intended for human consumption.
Example:

      fhem> xmllist
      <FHZINFO>
              <internal_LIST>
                      <internal name="global" state="internal" sets=""
                                attrs="room configfile logfile ...">
                              <INT key="DEF" value="<no definition>"/>
                              <INT key="NR" value="0"/>
                              <INT key="STATE" value="internal"/>
          [...]

## Devices

### global

The global device is used to set different global attributes. It will be automatically defined, it cannot be deleted or renamed and has no set or get parameters
Define

N/A

Set

N/A

Get

N/A

Attributes

- autoload_undefined_devices
  If set, automatically load the corresponding module when a message of this type is received. This is used by the autocreate device, to automatically create a fhem device upon receiving a corresponding message.
- allowfrom
  Comma (,) separated list of ip-addresses or hostnames. If set, only connections from these addresses are allowed.
- configfile
  Contains the name of the fhem configuration file. If save is called without argument, then the output will be written to this file.
- holiday2we
  If this attribute is set, then the $we variable will be true, if the value of the holiday variable referenced by this attribute is not none.
  Example:
  attr global holiday2we hessen
- lastinclude
  If this attribute is set, then the last command of the generated configfile (see the save command) will be
  include <lastinclude-value>
  This attribute is DEPRECATED, use notify, with the INITIALIZED event to execute commands after initialization.
- logfile
  Specify the logfile to write. You can use "-" for stdout, in this case the server won't background itself.
  The logfile name can also take wildcards for easier logfile rotation, see the FileLog section.
- modpath
  Specify the path to the modules directory `FHEM`. The path does not contain the directory FHEM. Upon setting the attribute, the directory will be scanned for filenames of the form NN_<NAME>.pm, and make them available for device definition under <NAME>. If the first device of type <NAME> is defined, the module will be loaded, and its function with the name <NAME>_Initialize will be called. Exception to this rule are modules with NN=99, these are considered to be utility modules containing only perl helper functions, they are loaded at startup (i.e. modpath attribute definition time).
- mseclog
  If set, the timestamp in the logfile will contain a millisecond part.
- nofork
  If set and the logfile is not "-", do not try to background. Needed on some Fritzbox installations.
- pidfilename
  Write the process id of the perl process to the specified file. The server runs as a daemon, and some distributions would like to check by the pid if we are still running. The file will be deleted upon shutdown.
- port
  Listen on the TCP/IP port `<number>` for incoming connections. To offer at least a little bit of security, the server will only listen for connections from the localhost per default. If there is a second value "global" then the server will listen for non-localhost connections too.
  To use IPV6, specify the port as IPV6:<number>, in this case the perl module IO::Socket:INET6 will be requested. On Linux you may have to install it with cpan -i IO::Socket::INET6 or apt-get libio-socket-inet6-perl; the OSX perl already has this module.
- statefile
  Set the filename where the state and certain at information will be saved before shutdown. If it is not specified, then no information will be saved.
- title
  Used by the web frontend fhemweb.pl (webpgm2) as a Page title.
- userattr
  A space separated list which contains the names of additional attributes. Without specifying them you will not be able to set them (in order to prevent typos).
- verbose
  Set the verbosity level. Possible values:
  - 0 - server start/stop
  - 1 - error messages or unknown packets
  - 2 - major events/alarms.
  - 3 - commands sent out will be logged.
  - 4 - you'll see whats received by the different devices.
  - 5 - debugging.
  Recommended level is 3 for normal use.
- dupTimeout
  Define the timeout for which 2 identical events from two different receiver are considered a duplicate. Default is 0.5 seconds.

### FHZ

Note: this module requires the Device::SerialPort or Win32::SerialPort module if the devices is connected via USB or a serial port.
Define

`define <name> FHZ <serial-device>`
Specifies the serial port to communicate with the FHZ1000PC or FHZ1300PC. The name(s) of the serial-device(s) depends on your distribution.
If the serial-device is called none, then no device will be opened, so you can experiment without hardware attached.
The program can service multiple devices, FS20 and FHT device commands will be sent out through the last FHZ device defined before the definition of the FS20/FHT device. To change the association, use the IODev attribute.
For GNU/Linux you may want to read our hints for GNU/Linux about multiple USB devices.
Note:The firmware of the FHZ1x00 will drop commands if the airtime for the last hour would exceed 1% (which corresponds roughly to 163 commands). For this purpose there is a command counter for the last hour (see list FHZDEVICE), which triggers with "TRANSMIT LIMIT EXCEEDED" if there were more than 163 commands in the last hour.
If you experience problems (for verbose 4 you get a lot of "Bad CRC message" in the log), then try to define your device as
`define <name> FHZ <serial-device> strangetty`

Set

`set FHZ <variable> [<value>]`
where `value` is one of:

FHTcode
initFS20
initHMS
stopHMS
initfull
raw
open
reopen
close
time

Notes:

- raw is used to send out "raw" FS20/FHT messages ("setters" only - no query messages!). See message byte streams in FHEM/00_FHZ.pm and the doc directory for some examples.
- In order to set the time of your FHT's, schedule this command every minute:
  `define fhz_timer at +*00:01:00 set FHZ time`
  See the loglevel to prevent logging of this command.
- FHTcode is a two digit hex number (from 00 to 63?) and sets the central FHT code, which is used by the FHT devices. After changing it, you must reprogram each FHT80b with: PROG (until Sond appears), then select CEnt, Prog, Select nA.
- If the FHT ceases to work for FHT devices whereas other devices (e.g. HMS, KS300) continue to work, a
  `set FHZ initfull`
  command could help. Try
  `set FHZ reopen`
  if the FHZ ceases to work completely. If all else fails, shutdown fhem, unplug and replug the FHZ device. Problems with FHZ may also be related to long USB cables or insufficient power on the USB - use a powered hub to improve this particular part of such issues. See our USB page for detailed USB / electromag. interference troubleshooting.
- `initfull` issues the initialization sequence for the FHZ device:

                  get FHZ init2
                  get FHZ serial
                  set FHZ initHMS
                  set FHZ initFS20
                  set FHZ time
                  set FHZ raw 04 01010100010000

- `reopen` closes and reopens the serial device port. This implicitly initializes the FHZ and issues the `initfull` command sequence.
- `stopHMS` probably is the inverse of `initHMS` (I don't have authoritative info on what exactly it does).
- `close` closes and frees the serial device port until you open it again with `open`, e.g. useful if you need to temporarily unload the ftdi_sio kernel module to use the bit-bang mode.

Get

`get FHZ <value>`
where `value` is one of:

init1
init2
init3
serial
fhtbuf

Notes:

- The mentioned codes are needed for initializing the FHZ1X00
- The answer for a command is also displayed by `list FHZ`
- The FHZ1x00PC has a message buffer for the FHT (see the FHT entry in the set section). If the buffer is full, then newly issued commands will be dropped, if the attribute fhtsoftbuffer is not set. `fhtbuf` returns the free memory in this buffer (in hex), an empty buffer in the FHZ1000 is 2c (42 bytes), in the FHZ1300 is 4a (74 bytes). A message occupies 3 + 2x(number of FHT commands) bytes, this is the second reason why sending multiple FHT commands with one set is a good idea. The first reason is, that these FHT commands are sent at once to the FHT.

Attributes

- do_not_notify
  Disable FileLog/notify/inform notification for a device. This affects the received signal, the set and trigger commands.
- dummy
- showtime
- loglevel
  Set the device loglevel to e.g. 6 if you do not wish messages from a given device to appear in the global logfile (FHZ/FS20/FHT). E.g. to set the FHT time, you should schedule "set FHZ time" every minute, but this in turn makes your logfile unreadable. These messages will not be generated if the FHZ attribute loglevel is set to 6.
- model (fhz1000,fhz1300)
- fhtsoftbuffer
  As the FHZ command buffer for FHT devices is limited (see fhtbuf), and commands are only sent to the FHT device every 120 seconds, the hardware buffer may overflow and FHT commands get lost. Setting this attribute implements an "unlimited" software buffer.
  Default is disabled (i.e. not set or set to 0).

### FS20

The FS20 protocol is used by a wide range of devices, which are either of the sender/sensor category or the receiver/actuator category. The radio (868.35 MHz) messages are either received through an FHZ or an CUL device, so this must be defined first.
Define

`define <name> FS20 <housecode> <button> [fg <fgaddr>] [lm <lmaddr>] [gm FF]`
The values of housecode, button, fg, lm, and gm can be either defined as hexadecimal value or as ELV-like "quad-decimal" value with digits 1-4. We will reference this ELV-like notation as ELV4 later in this document. You may even mix both hexadecimal and ELV4 notations, because FHEM can detect the used notation automatically by counting the digits.

- `<housecode>` is a 4 digit hex or 8 digit ELV4 number, corresponding to the housecode address.
- `<button>` is a 2 digit hex or 4 digit ELV4 number, corresponding to a button of the transmitter.
- The optional `<fgaddr>` specifies the function group. It is a 2 digit hex or 4 digit ELV address. The first digit of the hex address must be F or the first 2 digits of the ELV4 address must be 44.
- The optional `<lmaddr>` specifies the local master. It is a 2 digit hex or 4 digit ELV address. The last digit of the hex address must be F or the last 2 digits of the ELV4 address must be 44.
- The optional gm specifies the global master, the address must be FF if defined as hex value or 4444 if defined as ELV4 value.

Examples:

`define lamp FS20 7777 00 fg F1 gm F`
`define roll1 FS20 7777 01`
`define otherlamp FS20 24242424 1111 fg 4412 gm 4444`
`define otherroll1 FS20 24242424 1114`

Set

`set <name> <value> [<time>]`
where `value` is one of:

        dim06% dim12% dim18% dim25% dim31% dim37% dim43% dim50%
        dim56% dim62% dim68% dim75% dim81% dim87% dim93% dim100%
        dimdown
        dimup
        dimupdown
        off
        off-for-timer
        on                # dimmer: set to value before switching it off
        on-for-timer      # see the note
        on-old-for-timer  # set to previous (before switching it on)
        ramp-on-time      # time to reach the desired dim value on dimmers
        ramp-off-time     # time to reach the off state on dimmers
        reset
        sendstate
        timer
        toggle            # between off and previous dim val
        on-till           # Special, see the note

Examples:

`set lamp on`
`set lamp1,lamp2,lamp3 on`
`set lamp1-lamp3 on`
`set lamp on-for-timer 12`

Notes:

- Use reset with care: the device forgets even the housecode.
- As the FS20 protocol needs about 0.22 seconds to transmit a sequence, a pause of 0.22 seconds is inserted after each command.
- The FS20ST switches on for dim*%, dimup. It does not respond to sendstate.
- If the timer is set (i.e. it is not 0) then on, dim*, and *-for-timer will take it into account (at least by the FS20ST).
- The `time` argument ranges from 0.25sec to 4 hours and 16 minutes. As the time is encoded in one byte there are only 112 distinct values, the resolution gets coarse with larger values. The program will report the used timeout if the specified one cannot be set exactly. The resolution is 0.25 sec from 0 to 4 sec, 0.5 sec from 4 to 8 sec, 1 sec from 8 to 16 sec and so on. If you need better precision for large values, use at which has a 1 sec resolution.
- If the attribute follow-on-for-timer is set for the device and the on-for-timer command is sent to the device with a time parameter, the program automatically schedules a "setstate off" for the specified time.
- on-till requires an absolute time in the "at" format (HH:MM:SS, HH:MM or { <perl code> }, where the perl-code returns a time specification). If the current time is greater than the specified time, then the command is ignored, else an "on" command is generated, and for the given "till-time" an off command is scheduleld via the at command.

N/A

Attributes

- IODev
  Set the IO or physical device which should be used for sending signals for this "logical" device. An example for the physical device is an FHZ or a CUL. Note: Upon startup fhem assigns each logical device (FS20/HMS/KS300/etc) the last physical device which can receive data for this type of device. The attribute IODev needs to be used only if you attached more than one physical device capable of receiving signals for this logical device.
- eventMap
  Replace event names and set arguments. The value of this attribute consists of a list of space separated values, each value is a colon separated pair. The first part specifies the "old" value, the second the new/desired value. If the first character is slash(/) or komma(,) then split not by space but by this character, enabling to embed spaces. Examples:
  `attr store eventMap on:open off:closed
  attr store eventMap /on-for-timer 10:open/off:closed/
  set store open`
- do_not_notify
- dummy
  Set the device attribute dummy to define devices which should not output any radio signals. Associated notifys will be executed if the signal is received. Used e.g. to react to a code from a sender, but it will not emit radio signal if triggered in the web frontend.
- follow-on-for-timer
  the program automatically schedules a "setstate off" for the time specified as argument to the on-for-timer command (for the specified device only).
- loglevel
- showtime
- model
  The model attribute denotes the model type of the device. The attributes will (currently) not be used by the fhem.pl directly. It can be used by e.g. external programs or web interfaces to distinguish classes of devices and send the appropriate commands (e.g. "on" or "off" to a fs20st, "dim..%" to fs20du etc.). The spelling of the model names are as quoted on the printed documentation which comes which each device. This name is used without blanks in all lower-case letters. Valid characters should be `a-z 0-9` and `-` (dash), other characters should be ommited. Here is a list of "official" devices:
  Sender/Sensor: fs20fms fs20hgs fs20irl fs20kse fs20ls fs20pira fs20piri fs20piru fs20s16 fs20s20 fs20s4 fs20s4a fs20s4m fs20s4u fs20s4ub fs20s8 fs20s8m fs20sd fs20sn fs20sr fs20ss fs20str fs20tc1 fs20tc6 fs20tfk fs20tk fs20uts fs20ze
  Dimmer: fs20di fs20di10 fs20du
  Receiver/Actor: fs20as1 fs20as4 fs20ms2 fs20rgbsa fs20rst fs20rsu fs20sa fs20sig fs20sm4 fs20sm8 fs20st fs20su fs20sv fs20ue1 fs20usr fs20ws1
- ignore
  Ignore this device, e.g. if it belongs to your neighbour. The device won't trigger any FileLogs/notifys, issued commands will silently ignored (no RF signal will be sent out, just like for the dummy attribute). The device won't appear in the list command (only if it is explicitely asked for it), nor will it appear in commands which use some wildcard/attribute as name specifiers (see devspec). You still get them with the "ignored=1" special devspec.

Generated events:

From an FS20 device you can receive one of the following events.
- on
- off
- toggle
- dimdown
- dimup
- dimupdown
- on-for-timer Which event is sent is device dependent and can sometimes configured on the device.

### FHT

Fhem can receive FHT radio (868.35 MHz) messages either through an FHZ or an CUL device, so this must be defined first.
Define

`define <name> FHT <housecode>`
`<housecode>` is a four digit hex number, corresponding to the address of the FHT80b device.
Examples:

`define wz FHT 3232`

See the FHT section in set for more.

Set

`set <name> <valuetype> <value>`
where `value` is one of:

          desired-temp
          day-temp night-temp
          report1 report2
          refreshvalues
          mode
          holiday1 holiday2      # Not verified
          manu-temp              # No clue what it does.
          year month day hour minute
          time date
          lowtemp-offset         # Alarm-Temp.-Differenz
          windowopen-temp
          mon-from1 mon-to1 mon-from2 mon-to2
          tue-from1 tue-to1 tue-from2 tue-to2
          wed-from1 wed-to1 wed-from2 wed-to2
          thu-from1 thu-to1 thu-from2 thu-to2
          fri-from1 fri-to1 fri-from2 fri-to2
          sat-from1 sat-to1 sat-from2 sat-to2
          sun-from1 sun-to1 sun-from2 sun-to2

Examples:

`set wz desired-temp 22.5`
`set fl desired-temp 20.5 day-temp 19.0 night-temp 16.0`

Notes:

- Following events are reported (more or less regularly) by each FHT device: `measured-temp actuator actuator1...actuator8 warnings`
  You can use these strings for notify or FileLog definitions.
  - warnings can contain following strings: none, Battery low,Temperature too low, Window open, Fault on window sensor
  - actuator (without a suffix) stands for all actuators.
  - actuator or actuator1..8 can take following values:
    - <value>%
      This is the normal case, the actuator is instructed to open to this value.
    - offset <value>%
      The actuator is running with this offset.
    - lime-protection
      The actuator was instructed to execute the lime-protection procedure.
    - synctime
      If you select Sond/Sync on the FHT80B, you'll see a count down.
    - test
      The actuator was instructed by the FHT80b to emit a beep.
    - pair
      The the FHT80b sent a "you-belong-to-me" to this actuator.
- The FHT is very economical (or lazy), it accepts one message from the FHZ1x00 every 115+x seconds, where x depends on the housecode. Don't be surprised if your command is only accepted 10 minutes later by the device. FHT commands are buffered in the FHZ1x00/CUL till they are sent to the FHT, see the related `fhtbuf` entry in the `get` section.
  You can send up to 8 commands in one message at once to the FHT if you specify them all as arguments to the same set command, see the example above.
- time sets hour and minute to local time
- date sets year, month and date to local time
- refreshvalues is an alias for report1 255 report2 255
- All `*-temp` values need a temperature as argument, which will be rounded to 0.5 Celsius.
  Temperature values must between 5.5 and 30.5 Celsius. Value 5.5 sets the actuator to OFF, value 30.5 set the actuator to ON
- `mode` is one of `auto, manual, holiday or holiday_short.`
  If the mode is holiday, then
  - holiday1 sets the end-time of the holiday, in 10-minute steps
  - holiday2 sets the end-day of the holiday
  For holiday_short (party mode)
  - holiday1 sets the absolute hour to switch back from this mode (in 10-minute steps, max 144)
  - holiday2 sets the day of month to switch back from this mode (if holiday1 exceeds 144, subtract 144 and increase holiday2 with 1). Example:
    - current date is 29 Jan, time is 18:05
    - you want to switch to party mode until tomorrow 1:00
    - set holiday1 to 6 (6 x 10min = 1hour) and holiday2 to 30
- The `*-from1/*-from2/*-to1/*-to2` valuetypes need a time spec as argument in the HH:MM format. They define the periods, where the day-temp is valid. The minute (MM) will be rounded to 10, and 24:00 means off.
- To synchronize the FHT time and to "wake" muted FHTs it is adviseable to schedule following command:
  `define fht_sync at +*3:30 set TYPE=FHT time`
- `report1` with parameter 255 requests all settings for monday till sunday to be sent. The argument is a bitfield, to request unique values add up the following:
  - 1: monday
  - 2: tuesday
  - 4: thursday
  - 8: wednesday
  - 16: friday
  - 32: saturday
  - 64: sunday
  measured-temp and actuator is sent along if it is considered appropriate by the FHT.
  Note: This command generates a lot of RF traffic, which can lead to further problems, especially if the reception is not clear.
- `report2` with parameter 255 requests the following settings to be reported: day-temp night-temp windowopen-temp lowtemp-offset desired-temp measured-temp mode warnings. The argument is (more or less) a bitfield, to request unique values add up the following:
  - 1: warnings
  - 2: mode
  - 4: day-temp, night-temp, windowopen-temp
  - 64: lowtemp-offset
  measured-temp and actuator is sent along if it is considered appropriate by the FHT.
- `lowtemp-offset` needs a temperature as argument, valid values must be between 1.0 and 5.0 Celsius.
  It will trigger a warning if `desired-temp - measured-temp > lowtemp-offset` in a room for at least 1.5 hours after the last desired-temp change.
- FHEM optionally has an internal software buffer for FHT devices. This buffer should prevent transmission errors. If there is no confirmation for a given period, FHEM resends the command. You can see the queued commands with list <fht-device>. See the fhtsoftbuffer, retrycount and minfhtbuffer attributes for details.
- If a buffer is still in the softbuffer, it will be sent in the following order:
  `desired-temp,mode,report1,report2, holiday1,holiday2,day-temp,night-temp, [all other commands]`

Attributes

- ignore
- do_not_notify
- dummy
  Note:It makes sense to define an FHT device even for an FHT8b, else you will receive "unknown FHT device, please define one" message for each FHT8b as the CUL is reporting the 8b valve messages. But you should set the dummy attribute for these devices, else the internal FHT buffer of the CUL will be filled with data for the 8b's which is never consumed. If the buffer is full, you'll get "EOB" messages from the CUL, and you cannot transmit any data to the 80b's
- loglevel
- model (fht80b)
- showtime
- IODev
- eventMap
- retrycount
  If the fhtsoftbuffer attribute is set, then resend commands `retrycount` times if after 240 seconds no confirmation message is received from the corresponding FHT device.
  Default is 3.
- minfhtbuffer
  FHEM won't send commands to the FHZ if its fhtbuffer is below this value, default is 0. If this value is low, then the ordering of fht commands (see the note in the FHT section of set) has little effect, as only commands in the softbuffer can be prioritized. The maximum value should be 7 below the hardware maximum (see fhtbuf).
- lazy
  If the lazy attribute is set, FHEM won't send commands to the FHT if the current reading and the value to be set are already identical. This may help avoiding conflicts with the max-1%-time-on-air rule in large installations. Not set per default.
- tmpcorr
  Correct the temperature reported by the FHT by the value specified. Note: only the measured-temp value reported by fhem (used for logging) will be modified.

### FHT8V

Fhem can directly control FHT8V type valves via a CUL device without an intermediate FHT. This paragraph documents one of the building blocks, the other is the PID device.
Define

`define <name> FHT <housecode> [IODev]`
`<housecode>` is a four digit hex number, and must have the following relation to the housecode of the corresponding CUL device:

given the CUL housecode as AABB, then this housecode must be of the form CCBB, where CC is greater or equal to AA, but less then AA+8.

This form is chosen so that the CUL can update all FHT8V valve states within 2 minutes.
`<IODev>` must be specified if the last defined CUL device is not the one to use. Usually this is done voa the IODev attribute, but as the address checked is performed at the definition, we must use an exception here.
Examples:

`define wz FHT8V 3232`

Set

- set <name> valve <value;>
  Set the valve to the given value (in percent, from 0 to 100).
- set <name> pair
  Pair the valve with the CUL.

Get

- get <name> valve
  Read back the valve position from the CUL FHT buffer, and convert it to percent (from 0 to 100).

Attributes

- IODev
- loglevel
- ignore
- loglevel
- eventMap

### PID

The PID device is a loop controller, used to set the value e.g of a heating valve dependent of the current and desired temperature.
Define

`define <name> PID sensor[:reading:regexp] actor[:cmd:min:max] [p i d]`
`sensor[:reading:regexp]` specifies the sensor, which is an already defined fhem device, e.g. a S300TH temperature sensor. The reading and regexp fields are necessary only for unknown devices (currently CUL_WS and HMS devices are "known"). Reading specifies the READINGS field of the sensor, and the regexp extracts the number from this field. E.g. for the complete definition for a CUL_WS device is: `s300th_dev:temperature:([\d\.]*)`
`actor[:cmd:min:max]` specifies the actor, which is an already defined fhem device, e.g. an FHT8V valve. The cmd, min and max fields are necessary only for unknown devices (currently FHT8V is "known"). cmd specifies the command name for the actor, min the minimum value and max the maximum value. The complete definition for an FHT8V device is:`fht8v_dev:valve:0:100`
p, i and d are the parameters use to controlling, see also the this wikipedia entry. The default values are around 25.5, 3 and 5.88, you probably need to tune these values. They can be also changed later.
Examples:

`define wz_pid PID wz_th wz_fht8v`

Set

- set <name> factors p i d
  Set the p, i and d factors, as described above.
- set <name> desired <value>
  Set the desired value (e.g. temperature). Note: until this value is not set, no command is issued.

### CUL_FHTTK

This module handles messages from the FHT80 TF "Fenster-Tür-Kontakt" (Window-Door-Contact) which are normally only acted upon by the FHT80B. With this module, FHT80 TFs are in a limited way (see Wiki for detailed explanation of TF's mode of operation) usable similar to HMS100 TFK. The name of the module was chosen as a) only CUL will spill out the datagrams and b) "TF" designates usually temperature+humidity sensors (no clue, why ELV didn't label this one "TFK" like with FS20 and HMS).
As said before, FHEM can receive FHT80 TF radio (868.35 MHz) messages only through an CUL device, so this must be defined first.
Define

`define <name> CUL_FHTTK <devicecode>`
`<devicecode>` is a six digit hex number, given to the FHT80 TF during production, i. e. it is not changeable. (Yes, it keeps this code after changing batteries as well.)
Examples:

`define TK_TEST CUL_FHTTK 965AB0`

### HMS

Define

`define <name> HMS <housecode>`
`<housecode>` is a four digit hex number, corresponding to the address of the HMS device.
Examples:

`define temp HMS 1234`

Notes:

- There is _NO_ guarantee that the code will work as expected in all circumstances, the authors are not liable for any damage occuring as a result of incomplete or buggy code
- Currently supported devices are the HMS100-T HMS100-TF HMS100-WD HMS100-MG HMS100-TFK HMS100-CO HMS100-FIT RM100-2 RM100-3
- The housecode of the HMS devices may change if the battery is renewed. In order to make life easier, you can define a "wildcard" device for each type of HMS device. First the real device-id will be checked, then the wildcard device id. The wildcards are:
  - 1000 for the HMS100-TF
  - 1001 for the HMS100-T
  - 1002 for the HMS100-WD
  - 1003 for the RM100-2
  - 1004 for the HMS100-TFK/li>
  - 1006 for the HMS100-MG
  - 1008 for the HMS100-CO
  - 100e for the HMS100-FIT
- Some battery low notifications are not yet implemented (RM100, HMS100WD).
- Please test your installation before relying on the functionality.

### HMLAN

The HMLAN is the fhem module for the eQ-3 HomeMatic LAN Configurator.
The fhem module will emulate a CUL device, so the CUL_HM module can be used to define HomeMatic devices.
In order to use it with fhem you must disable the encryption first with the "HomeMatic Lan Interface Configurator" (which is part of the supplied Windows software), by selecting the device, "Change IP Settings", and deselect "AES Encrypt Lan Communication".
This device can be used in parallel with a CCU and (readonly) with fhem. To do this:

- start the fhem/contrib/tcptee.pl program
- redirect the CCU to the local host
- disable the LAN-Encryption on the CCU for the Lan configurator
- set the dummy attribute for the HMLAN device in fhem

Define

`define <name> HMLAN <ip-address>[:port]`
port is 1000 by default. If the ip-address is called none, then no device will be opened, so you can experiment without hardware attached.

### CUL

The CUL/CUR/CUN is a family of RF devices sold by busware.de. With the opensource firmware (see this link) they are capable to receive and send different 868MHz protocols (FS20/FHT/S300/EM/HMS). It is even possible to use these devices as range extenders/routers, see the CUL_RFR module for details. Some protocols (FS20, FHT and KS300) are converted by this module so that the same logical device can be used, irrespective if the radio telegram is received by a CUL or an FHZ device. Other protocols (S300/EM) need their own modules. E.g. S300 devices are processed by the CUL_WS module if the signals are received by the CUL, similarly EMWZ/EMGZ/EMEM is handled by the CUL_EM module. It is possible to attach more than one device in order to get better reception, fhem will filter out duplicate messages. Note: this module may require the Device::SerialPort or Win32::SerialPort module if you attach the device via USB and the OS sets strange default parameters for serial devices. |

Define

`define <name> CUL <device> <FHTID>`
USB-connected devices (CUL/CUR/CUN):

<device> specifies the serial port to communicate with the CUL or CUR. The name of the serial-device depends on your distribution, under linux the cdc_acm kernel module is responsible, and usually a /dev/ttyACM0 device will be created. If your distribution does not have a cdc_acm module, you can force usbserial to handle the CUL by the following command:

modprobe usbserial vendor=0x03eb product=0x204b

In this case the device is most probably /dev/ttyUSB0.
You can also specify a baudrate if the device name contains the @ character, e.g.: /dev/ttyACM0@38400
If the baudrate is "directio" (e.g.: /dev/ttyACM0@directio), then the perl module Device::SerialPort is not needed, and fhem opens the device with simple file io. This might work if the operating system uses sane defaults for the serial parameters, e.g. some Linux distributions and OSX.

Network-connected devices (CUN):

<device> specifies the host:port of the device. E.g. 192.168.0.244:2323

If the device is called none, then no device will be opened, so you can experiment without hardware attached.
The FHTID is a 4 digit hex number, and it is used when the CUL/CUR talks to FHT devices or when CUR requests data. Set it to 0000 to avoid answering any FHT80b request by the CUL.

Set

- raw
  Issue a CUL firmware command. See the this document for details on CUL commands.
- freq / bWidth / rAmpl / sens
  SlowRF mode only.
  Set the CUL frequency / bandwidth / receiver-amplitude / sensitivity
  Use it with care, it may destroy your hardware and it even may be illegal to do so. Note: the parameters used for RFR transmission are not affected.
  - freq sets both the reception and transmission frequency. Note: although the CC1101 can be set to frequencies between 315 and 915 MHz, the antenna interface and the antenna of the CUL is tuned for exactly one frequency. Default is 868.3MHz (or 433MHz)
  - bWidth can be set to values between 58kHz and 812kHz. Large values are susceptible to interference, but make possible to receive inaccurate or multiple transmitters. It affects tranmission too. Default is 325kHz.
  - rAmpl is receiver amplification, with values between 24 and 42 dB. Bigger values allow reception of weak signals. Default is 42.
  - sens is the decision boundery between the on and off values, and it is 4, 8, 12 or 16 dB. Smaller values allow reception of less clear signals. Default is 4dB.
- hmPairForSec
  HomeMatic mode only.
  Set the CUL in Pairing-Mode for the given seconds. Any device set into pairing mode in this time will be paired with fhem.
- hmPairSerial
  HomeMatic mode only.
  Try to pair with the given device. The argument is a 10 character string, usually starting with letters and ending with digits, printed on the backside of the device. It is not necessary to put the given device in learning mode if it is a receiver.
- led
  Set the CUL led off (00), on (01) or blinking (02).

Get

- version
  return the CUL firmware version
- uptime
  return the CUL uptime (time since CUL reset).
- raw
  Issue a CUL firmware command, and wait for one line of data returned by the CUL. See the CUL firmware README document for details on CUL commands.
- fhtbuf
  CUL has a message buffer for the FHT. If the buffer is full, then newly issued commands will be dropped, if the attribute fhtsoftbuffer is not set. Instead, a "EOB" message is issued. `fhtbuf` returns the free memory in this buffer (in hex), an empty buffer in the CUL-V2 is 74 bytes, in CUL-V3/CUN 200 Bytes. A message occupies 3 + 2x(number of FHT commands) bytes, this is the second reason why sending multiple FHT commands with one set is a good idea. The first reason is, that these FHT commands are sent at once to the FHT.
- ccconf
  Read some CUL radio-chip (cc1101) registers (frequency, bandwidth, etc), and display them in human readable form.

Attributes

- do_not_notify
- dummy
- showtime
- loglevel
- model (CUL,CUN,CUR)
- sendpool
  If using more than one CUL/CUN for covering a large area, sending different events by the different CUL's might disturb each other. This phenomenon is also known as the Palm-Beach-Resort effect. Putting them in a common sendpool will serialize sending the events. E.g. if you have three CUN's, you have to specify following attributes:
  attr CUN1 sendpool CUN1,CUN2,CUN3
  attr CUN2 sendpool CUN1,CUN2,CUN3
  attr CUN3 sendpool CUN1,CUN2,CUN3
- addvaltrigger
  Create triggers for additional device values. Right now these are RSSI and RAWMSG for the CUL family and RAWMSG for the FHZ.
- rfmode
  Configure the RF Transceiver of the CUL (the CC1101). Available arguments are:
  - SlowRF
    To communicate with FS20/FHT/HMS/EM1010/S300/Hoermann devices @1kHz datarate. This is the default.
  - HomeMatic
    To communicate with HomeMatic type of devices @20kHz datarate
- hmId
  Set the HomeMatic ID of this device. If this attribute is absent, the ID will be F1<housecode>. Note 1: after setting or changing this attribute you have to relearn all your HomeMatic devices. Note 2: the value _must_ be a 6 digit hex number, and 000000 is not valid. fhem wont complain if it is not correct, but the communication won't work.
- hmProtocolEvents
  Generate events for HomeMatic protocol messages.

### CUL_WS

The CUL_WS module interprets S300 type of messages received by the CUL.
Define

`define <name> CUL_WS <code> [corr1...corr4]`
<code> is the code which must be set on the S300 device. Valid values are 1 through 8.
corr1..corr4 are up to 4 numerical correction factors, which will be added to the respective value to calibrate the device. Note: rain-values will be multiplied and not added to the correction factor.

### CUL_EM

The CUL_EM module interprets EM type of messages received by the CUL, notably from EMEM, EMWZ or EMGZ devices.
Define

`define <name> CUL_EM <code> [corr1 corr2 CostPerUnit BasicFeePerMonth]`
<code> is the code which must be set on the EM device. Valid values are 1 through 12. 1-4 denotes EMWZ, 5-8 EMEM and 9-12 EMGZ devices.
corr1 is used to correct the current number, corr2 for the total number.

- for EMWZ devices you should specify the rotation speed (R/kW) of your watt-meter (e.g. 150) for corr1 and 12 times this value for corr2
- for EMEM devices the corr1 value is 0.01, and the corr2 value is 0.001

CostPerUnit and BasicFeePerMonth are used to compute your daily and mothly fees. Your COST will appear in the log, generated once daiy (without the basic fee) or month (with the bassic fee included). Your definition should look like E.g.:

        define emwz 1 75 900 0.15 12.50

and the Log looks like:

        CUM_DAY: 6.849 CUM: 60123.4 COST: 1.02
        CUM_MONTH: 212.319 CUM: 60123.4 COST: 44.34

Tipp: You can configure your EMWZ device to show in the CUM column of the STATE reading the current reading of your meter. For this purpose: multiply the current reading (from the real device) with the corr1 value (RperKW), and substract the RAW CUM value from it. Now set the basis reading of your EMWZ device (named emwz) to this value.

### CUL_IR

The CUL_IR module interprets Infrared messages received by the CUN/CUNO/CUNOv2/TuxRadio. Those devices can receive Infrared Signals from basically any Remote controller and will transform that information in a so called Button-Code
Define

`define <name> CUL_IR <IODev>`
<IODev> is the devicename of the IR-receivung device, e.g. CUNO1.
Your definition should look like E.g.:

        define IR-Dev CUL_IR CUNO1

Set

- irLearnForSec
  Sets the CUL_IR device in an IR-Code Learning mode for the given seconds. Any received IR-Code will be stored as a Button attribute for this devices. The name of these attributes is dependent on the two attributes learncount and learnprefix.
  Attention: Before learning IR-Codes the CUL_IR device needs to be set in IR-Receiving mode by modifying the irReceive attribute.
- irSend
  Sends out IR-commands via the connected IODev. The IR-command can be specified as buttonname according to Button.* or as IR-Code directly. If a buttonname is specified, the corresponding IR-Code will be sent out.
  Example:

      set IR-Dev irSend ButtonA001

  If defining an IR-Code directly the following Code-Syntax needs to be followed:

      IRCode: <PP><AAAA><CCCC><FF>

  with P = Protocol; A = Address; C = Command; F = Flags
  With the Flags you can modify IR-Repetition. Flags between 00-0E will produce 0-15 IR-Repetitions. You can type the IR-Code as plain as above, or with a heading "I" as learnt for the buttons.
  Example:
  `set IR-Dev irSend 0A07070F0F02
  set IR-Dev irSend I0A07070F0F00`

Get

N/A

Attributes

- do_not_notify
- showtime
- loglevel
- irReceive
  Configure the IR Transceiver of the <IODev> (the CUNO1). Available arguments are:
  - OFF
    Switching off the reception of IR signals. This is the default.
  - ON
    Switching on the reception of IR signals. This is WITHOUT filtering repetitions. This is not recommended as many remote controls do repeat their signals.
  - ON_NR
    Switching on the reception of IR signals with filtering of repetitions. This is the recommended modus operandi.
- Button.*
  Button.* is the wildcard for all learnt IR-Codes. IR-Codes are learnt as Button-Attributes. The name for a learnt Button - IR-Code is compiled out of three elements:

              Button<learnprefix><learncount>

  When the CUL_IR device is set into learning mode it will generate a new button-attribute for each new IR-Code received.This is done according to the following syntax:

              <Button-Attribute-Name> <IR-Code>

  Examples of learnt button-attributes with EMPTY <learnprefix> and <learncount> starting from 1:

              Button001   I02029A000000
              Button002   I02029A000001

  To make sure that something happens when this IR-code is received later on one has to modify the attribute and to add commands as attribute values. Examples:

              Button001   I02029A000000   set WZ_Lamp on
              Button002   I02029A000001   set Switch on

  The syntax for this is:

              attr <device-name> <attribute-name> <IR-Code> <command>

- Group.*
  Group.* is the wildcard for IR-Code groups. With these attributes one can define IR-Code parts, which may match to several Button-IR-Codes.
  This is done by defining group-attributes that contain only parts of the IR-Code. The syntax is:

              <Group-Attribute-Name> <IR-Code>

  Examples of a group-attribute is:

              Group001   I02029A

  With this all IR-Codes starting with I02029A will match the Group001.
- learncount
  learncount is used to store the next button-code-number that needs to be learned. By manually modifying this attribute new button sequences can be arranged.
- learnprefix
  learnprefix is a string which will be added to the button-attribute-name.
  A button-attribute-name is constructed by:

              Button<learnprefix><learncount>

  If learnprefix is empty the button-attribute-name only contains the term "Button" and the actual number of learncount.

### ESA2000

The ESA2000 module interprets ESA2000 type of messages received by the CUL, currently only for ESA2000 LED devices.
Define

`define <name> ESA2000 <code> [base1 base2]`
<code> is the 4 digit HEX code identifying the devices.
base1/2 is added to the total kwh as a base (Hoch- und Niedertarifzählerstand).

### CUL_HM

Support for eQ-3 HomeMatic devices via the CUL or the HMLAN.
Prerequisites:

- If the interface is a CUL device, the rfmode attribute of the corresponding CUL/CUN device must be set to HomeMatic. Note: this mode is BidCos/Homematic only, you will not receive FS20/HMS/EM/S300 messages via this device. Previously defined FS20/HMS etc devices must be assigned to a different input device (CUL/FHZ/etc).
- The protocol used by HomeMatic devices (BidCos, known as AskSin in the culfw) must be enabled in the culfw firmware. This is done for all CUN and for newer CUL (i.e. V3.0 and greater) devices with culfw firmware version 1.38 and newer. For CUL hardware version before 3.0 there is a separate firmware with HomeMatic support which lacks FHT support.

Notes

- Currently supported device families: remote, switch, dimmer, blindActuator, motionDetector, smokeDetector, threeStateSensor, THSensor, winmatic. Special devices: KS550, HM-CC-TC and the KFM100.
- Device messages can only be interpreted correctly if the device type is known. fhem will extract the device type from a "pairing request" message, even if it won't respond to it (see hmPairSerial and hmPairForSec to enable pairing). As an alternative, set the correct subType and model attributes, for a list of possible subType values see "attr hmdevice ?".
- The so called "AES-Encryption" is in reality a signing request: if it is enabled, an actor device will only execute a received command, if a correct answer to a request generated by the actor is received. This means:
  - Reaction to commands is noticably slower, as 3 messages are sent instead of one before the action is processed by the actor.
  - Every command and its final ack from the device is sent in clear, so an outside observer will know the status of each device.
  - The firmware implementation is buggy: the "toggle" event is executed before the answer for the signing request is received, at least by some switches (HM-LC-Sw1-Pl and HM-LC-SW2-PB-FM).
  - The HMLAN configurator will answer signing requests by itself, and if it is configured with the 3-byte address of a foreign CCU (the address is part of the signing request), it is able to answer signing requests correctly. In the reality this will only work reliably if the foreign CCU is switched off, else it will also answer to the signing request in parallel, and the actor will not receive a clear confirmation.
  - AES-Encryption is not useable with a CUL device as the interface, but it is supported with a HMLAN. Due to the issues above I do not recommend using Homematic encryption at all.

Define

`define <name> CUL_HM <6-digit-hex-code>`
Normally this command is generated by the autocreate module, together with the necessary hmClass and subType attributes. Usually you issue a hmPairForSec command and press the corresponding button on the device to be paired, or issue a hmPairSerial set command if the device is a receiver and you know its serial number. Autocreate will then create a fhem device and set all necessary attributes. Without pairing the device will not accept messages from fhem.
If you cannot use autocreate, then you have to specify:

- the <6-digit-hex-code>
  which is the hardcoded address of the device (no, you cannot choose it arbitrarily like for FS20 devices). You may detect it by inspecting the fhem log.
- the hmClass attribute
  which is either sender or receiver
- the subType attribute
  which is one of switch dimmer blindActuator remote sensor swi pushButton threeStateSensor motionDetector keyMatic winMatic smokeDetector
  Without these attributes fhem won't be able to decode device messages appropriately.

Set

Note: devices which are normally send-only (remote/sensor/etc) must be set into pairing/learning mode in order to receive the following commands.
General commands (available to most hm devices):

- statusRequest
  Send a status request to the device.
- reset
  Factory reset the device. You need to pair it again to use it with fhem.
- pair
  Pair the device again with its known serialNumber (e.g. after a device reset).
- unpair
  "Unpair" the device, i.e. make it available to pair with other master devices.
- sign [on|off]
  Activate or deactivate signing (also called AES encryption, see the note above). Warning: if the device is attached via a CUL, you won't be able to switch it (or deactivate signing) from fhem before you reset the device directly.

subType (i.e family) dependent commands:

- switch
  - on - set the switch on
  - off - set the switch off
  - on-for-timer sec - set the switch on for the given seconds. Note: the protocol does not support an off-for-timer like FS20.
  - toggle - toggle the switch.
- dimmer, blindActuator
  - 0 - 100 with a resolution of 0.5:
    set the dimmer / blindActuator to the given value (in percent).
  - on / off
    this corresponds to 100 or 0 %.
- remotes
  devicepair hmDevice
  Pair a remote directly with a switch. The command for the switch is sent out directly, the remote must be set into learning mode first.
- 4Dis (HM-PB-4DIS-WM)
  - text <btn_no> [on|off] <text1> <text2>
    Set the text on the display of the device. To this purpose issue this set command first (or a number of them), and then choose from the teach-in menu of the 4Dis the "Central" to transmit the data. Example:
    set 4Dis text 1 on On Lamp
    set 4Dis text 1 off Kitchen Off
- Climate-Control (HM-CC-TC)
  - day-temp <tmp>
    night-temp <tmp>
    party-temp <tmp>
    desired-temp <tmp>
    Set different temperatures. Temp must be between 6 and 30 Celsius, and precision is half a degree.
  - tempListSat HH:MM temp ... 24:00 temp
    tempListSun HH:MM temp ... 24:00 temp
    tempListMon HH:MM temp ... 24:00 temp
    tempListTue HH:MM temp ... 24:00 temp
    tempListThu HH:MM temp ... 24:00 temp
    tempListWed HH:MM temp ... 24:00 temp
    tempListFri HH:MM temp ... 24:00 temp
    Specify a list of temperature intervals. Up to 24 intervals can be specified for each week day, the resolution is 10 Minutes. The last time spec must always be 24:00.
    Example: set th tempListSat 06:00 19 23:00 22.5 24:00 19

Debugging:

- raw <data> ...
  Only needed for experimentation. send a list of "raw" commands. The first command will be immediately sent, the next one after the previous one is acked by the target. The length will be computed automatically, and the message counter will be incremented if the first two charcters are ++. Example (enable AES):

         set hm1 raw ++A001F100001234560105000000001\
                     ++A001F10000123456010802010AF10B000C00\
                     ++A001F1000012345601080801\

### CUL_HOERMANN

The CUL_HOERMANN module registers the 868MHz Hoermann Garage-Door-Opener signals received by the CUL. Note: As the structure of this signal is not understood, no checksum is verified, so it is likely to receive bogus messages.

### CUL_RFR

The CUL_RFR module is used to "attach" a second CUL to your base CUL, and use it as a repeater / range extender. RFR is shorthand for RF_ROUTER. Transmission of the data uses the CC1101 packet capabilities with GFSK modulation at 250kBaud after pinging the base CUL at the usual 1kBaud. When configured, the RFR device can be used like another CUL connected directly to fhem. Before you can use this feature in fhem, you have to enable/configure RF ROUTING in both CUL's: First give your base CUL (which remains connected to the PC) an RFR ID by issuing the fhem command "set MyCUL raw ui0100". With this command the base CUL will get the ID 01, and it will not relay messages to other CUL's (as the second number is 00). Now replace the base CUL with the RFR CUL, and set its id by issuing the fhem command "set MyCUL raw ui0201". Now remove this CUL and attach the original, base CUL again. The RFR CUL got the id 02, and will relay every message to the base CUL with id 01. Take the RFR CUL, and attach it to an USB power supply, as seen on the image. As the configured base id is not 00, it will activate RF reception on boot, and will start sending messages to the base CUL. Now you have to define this RFR cul as a fhem device: |

Define

`define <name> CUL_RFR <own-id> <base-id>`
<own-id> is the id of the RFR CUL not connected to the PC, <base-id> is the id of the CUL connected to the PC. Both parameters have two characters, each representing a one byte hex number.
Example:

`set MyCUL raw ui0100`
# Now replace the base CUL with the RFR CUL
`set MyCUL raw ui0201`
# Reattach the base CUL to the PC and attach the RFR CUL to a USB power supply
`define MyRFR CUL_RFR 02 01`

Set

Same as for the CUL.

### EnOcean

Devices sold by numerous hardware verndors (e.g. Eltako, Peha, etc), using the RF Protocol provided by the EnOcean Alliance.
Define

`define <name> EnOcean <ID>`
Define an EnOcean device, connected via a TCM. The <ID> parameter is an 8 digit hex number. For remotes and sensors the autocreate module may help you.
Example:

`define switch1 EnOcean ffc54500`

Set

- MD15 commands. Note: The command is not sent until the MD15 wakes up and sends a mesage, usually every 10 minutes.
  - actuator <value>
    Set the actuator to the specifed percent value (0-100)
  - desired-temp <value>
    Use the builtin PI regulator, and set the desired temperature to the specified degree. The actual value will be taken from the temperature reported by the MD15 or from the attribute actualTemp if it is set
  - unattended
    Do not regulate the MD15.
- all other:
  `set switch1 <value>`
  where `value` is one of A0,AI,B0,BI,C0,CI,D0,DI, combinations of these and released, in fact we are trying to emulate a PTM100 type remote.
  If you define an eventMap attribute with on/off, then you'll be able to easily set the device from the WEB frontend.
  In order to control devices, you cannot reuse the ID's of other devices (like remotes), instead you have to create your own, which must be in the allowed ID-Range of the underlying IO device. For this first query the TCM with the "`get <tcm> idbase`" command. You can use up to 128 ID's starting with the base shown there. If you are using an ID outside of the allowed range, you'll see an ERR_ID_RANGE message in the fhem log.
  Example:
  `set switch1 BI
  set switch1 B0,CI
  attr eventMap BI:on B0:off
  set switch1 on
  `

### EM

Define

`define <name> EM <em1010pc-device>`
Define a EM1010PC USB device. As the EM1010PC was not designed to be used with a PC attached to it all the time, it won't transmit received signals automatically, fhem has to poll it every 5 minutes.
Currently there is no way to read the internal log of the EM1010PC with fhem, use the program em1010.pl in the contrib directory for this purpose.
Examples:

`define em EM /dev/elv_em1010pc`

Set

`set EM <value>`
where `value` is either time or reset.
If time has arguments of the form YYYY-MM-DD HH:MM:SS, then the specified time will be set, else the time from the host.
Note: after reset you should set the time.

Get

`get EM <value>`
where `value` is either version or time.

Attributes

- model (em1010pc)
- dummy
- loglevel

### EMWZ

Define

`define <name> EMWZ <device-number>`
Define up to 4 EM1000WZ attached to the EM1010PC. The device number must be between 1 and 4. Defining an EMWZ will schedule an internal task, which reads the status of the device every 5 minutes, and triggers notify/filelog commands.
Example:

`define emwz EMWZ 1`

Set

`set EMWZdevice <param> <value>`
where param is one of:

- rperkw
  Number of rotations for a KiloWatt of the EM1000WZ device (actually of the device where the EM1000WZ is attached to). Without setting this correctly, all other readings will be incorrect.
- alarm
  Alarm in WATT. if you forget to set it, the default value is rediculously low (random), and if a value above this threshold is received, the EM1010PC will start beeping once every minute. It can be very annoying.
- price
  The price of one KW in EURO (use e.g. 0.20 for 20 Cents). It is used only on the EM1010PC display, it is of no interest for FHEM.

Get

`get EMWZ status`
This is the same command which is scheduled every 5 minutes internally.

### EMGZ

Define

`define <name> EMGZ <device-number>`
Define up to 4 EM1000GZ attached to the EM1010PC. The device number must be between 9 and 12. Defining an EMGZ will schedule an internal task, which reads the status of the device every 5 minutes, and triggers notify/filelog commands.
Example:

`define emgz EMGZ 9`

Set

`set EMGZdevice <param> <value>`
where param is:

- price
  The price of one KW in EURO (use e.g. 0.20 for 20 Cents). It is used only on the EM1010PC display, it is of no interest for FHEM.

### KM271

KM271 is the name of the communication device for the Buderus Logamatic 2105 or 2107 heating controller. It is connected via a serial line to the fhem computer. The fhem module sets the communication device into log-mode, which then will generate an event on change of the inner parameters. There are about 20.000 events a day, the FHEM module ignores about 90% of them, if the all_km271_events attribute is not set.
Note: this module requires the Device::SerialPort or Win32::SerialPort module.
Define

`define <name> KM271 <serial-device-name>`
Example:

`define KM271 KM271 /dev/ttyS0`

Set

`set KM271 <param> [<value>]`
where param is one of:

- hk1_nachtsoll <temp>
  (0.5 celsius resolution)
- hk1_tagsoll <temp>
  (0.5 celsius resolution)
- hk1_betriebsart [automatik|nacht|tag]

- Brenneransteuerung
- Brennerlaufzeit
- Brennerschalttemperatur
- Heizkennlinie
- Kesselbetrieb
- Kesselintegral
- Ladepumpe
- Raumsolltemperatur_HK1

All of these events are reported directly after initialization (or after requesting logmode), along with some 60 configuration records (6byte long each). About 20 parameters from these records are reverse engeneered, they all start with CFG_.

### KS300

Fhem can receive the KS300 radio (868.35 MHz) messages through FHZ, WS300 or an CUL device, so one of them must be defined first.
This module services messages received by the FHZ device, if you use one of the other alternetives, see the WS300 or CUL_WS entries.
Note: The KS555 is also reported to work.
Define

`define <name> KS300 <housecode> [ml/raincounter [wind-factor]]`
`<housecode>` is a four digit hex number, corresponding to the address of the KS300 device, right now it is ignored. The ml/raincounter defaults to 255 ml, but it must be specified if you wish to set the wind factor, which defaults to 1.0.
Examples:

`define ks1 KS300 1234`

- rainadjustment
  If this attribute is set, fhem automatically accounts for rain counter resets after a battery change and random counter switches as experienced by some users. The raw rain counter values are adjusted by an offset in order to flatten out the sudden large increases and decreases in the received rain counter values. Default is off.

### CM11

Note: this module requires the Device::SerialPort or Win32::SerialPort module.
Define

`define <name> CM11 <serial-device>`
CM11 is the X10 module to interface X10 devices with the PC.
The current implementation can evaluate incoming data on the powerline of any kind. It can send on, off, dimdown and dimup commands.
The name of the serial-device depends on your distribution. If serial-device is none, then no device will be opened, so you can experiment without hardware attached.
If you experience problems (for verbose 4 you get a lot of "Bad CRC message" in the log), then try to define your device as
`define <name> FHZ <serial-device> strangetty`
Example:

`define x10if CM11 /dev/ttyUSB3`

Set

`set <name> reopen`
Reopens the serial port.

Get

`get <name> fwrev`
Reads the firmware revision of the CM11 device. Returns `error` if the serial connection to the device times out. Can be used for error detection.
`get <name> time`
Reads the internal time of the device which is the total uptime (modulo one year), since fhem sets the time to 0.00:00:00 if the device requests the time to be set after being powered on. Returns `error` if the serial connection to the device times out. Can be used for error detection.

Attributes

- do_not_notify
- dummy
- loglevel
- model (CM11)

### X10

Define

`define <name> X10 <model> <housecode> <unitcode>`
Defines an X10 device via its model, housecode and unitcode.
Notes:

- `<model>` is one of
  - `lm12`: lamp module, dimmable
  - `lm15`: lamp module, not dimmable
  - `am12`: appliance module, not dimmable
  - `tm12`: tranceiver module, not dimmable. Its unitcode is 1.
  Model determines whether a dim command is reasonable to be sent or not.
- `<housecode>` ranges from A to P.
- `<unitcode>` ranges from 1 to 16.

Examples:

`define lamp1 X10 lm12 N 10`
`define pump X10 am12 B 7`
`define lamp2 X10 lm15 N 11`

Set

`set <name> <value> [<argument>]`
where `value` is one of:

        dimdown           # requires argument, see the note
        dimup             # requires argument, see the note
        off
        on
        on-till           # Special, see the note
        on-for-timer      # Special, see the note

Examples:

`set lamp1 dimup 10`
`set lamp1,lamp2 off`
`set pump off`
`set lamp2 on-till 19:59`
`set lamp2 on-for-timer 00:02:30`

Notes:

- Only switching and dimming are supported by now.
- Dimming is valid only for a dimmable device as specified by the `model` argument in its `define` statement.
- An X10 device has 210 discrete brightness levels. If you use a X10 sender, e.g. a remote control or a wall switch to dim, a brightness step is 100%/210.
- `dimdown` and `dimup` take a number in the range from 0 to 22 as argument. It is assumed that argument 1 is a 1% brightness change (microdim) and arguments 2 to 22 are 10%..100% brightness changes. The meaning of argument 0 is unclear.
- This currently leads to some confusion in the logs as the `dimdown` and `dimup` codes are logged with different meaning of the arguments depending on whether the commands were sent from the PC or from a remote control or a wall switch.
- `dimdown` and `dimup` from on and off states may have unexpected results. This seems to be a feature of the X10 devices.
- `on-till` requires an absolute time in the "at" format (HH:MM:SS, HH:MM) or { <perl code> }, where the perl code returns a time specification). If the current time is greater than the specified time, then the command is ignored, else an "on" command is generated, and for the given "till-time" an off command is scheduleld via the at command.
- `on-for-timer` requires a relative time in the "at" format (HH:MM:SS, HH:MM) or { <perl code> }, where the perl code returns a time specification).

### LIRC

Use infrared signals received by an lirc device as toggle events.
Note: this module needs the Lirc::Client perl module.
Define

define <name> LIRC <lircrc_file>
Example:

define Lirc LIRC /etc/lirc/lircrc

Note: In the lirc configuration file you have to define each possible event. If you have this configuration

        begin
          prog = fhem
          button = pwr
          config = IrPower
        end

and you press the pwr button the IrPower toggle event occures at fhem.

        define IrPower01 notify IrPower set lamp toggle

turns the lamp on and off. If you want a faster reaction to keypresses you have to change the defaultvalue of readytimeout from 5 seconds to e.g. 1 second in fhem.pl

### WS300

Define

`define WS300Device WS300 <serial device>`
or
`define <devname> WS300 [0-9]`
The first line is mandatory if you have a WS300 device: it defines the input device with its USB port. The name of this device is fixed and must be WS300Device. It must be the first defined WS300 device.
For each additional device (with number 0 to 9) you have to define another WS300 device, with an arbitrary name. The WS300 device which reports the readings will be defined with the port number 9, an optional KS300 with the port number 8.
Examples:

          define WS300Device  WS300   /dev/ttyUSB1
          define ash2200.1    WS300   0
          define ks300        WS300   8
          define ws300        WS300   9

### Weather

Define

`define <name> Weather <location> [<interval> [en|de|fr|es]]`
Defines a virtual device for weather forecasts. You need to have the perl module Weather::Google installed to use this device. If you do not have it, use cpan -i Weather::Google to install it.
A Weather device periodically gathers current and forecast weather conditions from the Google Weather API.
The parameter `location` is any string that is recognized as a location, either a town name or a zip code. Browse to the URL `http://www.google.de/ig/api?weather=location&hl=en` to see the raw output for your location.
The optional parameter `interval` is the time between subsequent updates in seconds. It defaults to 3600 (1 hour).
The optional language parameter may be one of `en`, `de`, `fr`, `es`. It determines the natural language in which the forecast information appears. It defaults to en. If you want to set the language you also have to set the interval.
Examples:

          define MyWeather Weather "Frankfurt,HE"
          define Forecast Weather "Amsterdam,NL" 1800
          define weather Weather "30000,France" 3600 fr

city | name of town returned for location
condition | current condition, one of Sunny, Clear, Partly Cloudy, Mostly Cloudy, Overcast, Chance of Rain
current_date_time | last update of forecast on server
fc?_condition | forecast condition
fc?_day_of_week | day of week for day +?
fc?_high_c | forecasted daily high in degrees centigrade
fc?_icon | relative path for forecast icon, prefix with `http://www.google.com` to form a valid URL for display in web interfaces
fc?_low_c | forecasted daily low in degrees centigrade
humidity | current humidity

### USF1000

Fhem can receive your tank's fill level from the USF1000S device through a FHZ device, so one must be defined first. The state contains the fill level in % (lower case v in the device state) and the current volume in liters (upper case V in the device state). Measured distance to the liquid's surface, fill level, volume and warnings (Test mode, Battery low) are available. Due to the design of the USF1000S protocol, you can have only one USF1000S in range of your FHZ as these devices cannot be distinguished.
Define

`define <name> USF1000 <geometry>`
`<geometry>` determines the form of the tank and the position of the sensor. The following geometries are currently supported:

- `cub <length> <width> <height> <offset>`
- `cylv <diameter> <height> <offset>`

`cub` stands for a cuboid whose base is <length> × <width>. `cylv` stands for a vertical cylinder whose diameter is <diameter>. <height> is the distance of the surface of the liquid from the ground if the tank is full. <offset> is the distance of the sensor relative to the surface of the liquid. All quantities are expressed in meters.
Example:

`define MyTank USF1000 cylv 2 1 0.3`: a cylindrical water tank with 2 meters diameter. The water stands 1 meter high if the tank is full. The sensor is fixed 1,3 meters above ground.

### BS

The module BS allows to collect data from a brightness sensor through a FHZ device. For details on the brightness sensor see busware wiki. You can have at most nine different brightness sensors in range of your FHZ.
The state contains the brightness in % (reading `brightness`) and the brightness in lux (reading `lux`). The `flags` reading is always zero. The meaning of these readings is explained in more detail on the above mentioned wiki page.
Define

`define <name> BS <sensor#> [<RExt>]`
`<sensor#>` is the number of sensor in the brightness sensor address system that runs from 1 to 9.
`<RExt>` is the value of the resistor on your brightness sensor in Ω (Ohm). The brightness reading in % is proportional to the resistance, the lux reading is proportional to the resistance squared. The value is optional. The default resistance is RExt= 50.000Ω.
Example:

`define bs1 BS 1 40000`

### SCIVT

Define

`define <name> SCIVT <SCD-device>`
Define a SCD series solar controler device. Details see here. You probably need a Serial to USB controller like the PL2303.
Defining an SCIVT device will schedule an internal task, which reads the status of the device every 5 minutes, and triggers notify/filelog commands.
Note: Currently this device does not support a "set" function, only a single get function which reads the device status immediately.
Example:

`define scd SCIVT /dev/ttyUSB2`

Set

N/A

Get

`get SCVIT data`

Attributes

- loglevel
- model (SCD)

### ECMD

Any physical device with request/response-like communication capabilities over a TCP connection can be defined as ECMD device. A practical example of such a device is the AVR microcontroller board AVR-NET-IO from Pollin with ECMD-enabled Ethersex firmware.

A physical ECMD device can host any number of logical ECMD devices. Logical devices are defined as ECMDDevices in fhem. ADC 0 to 3 and I/O port 0 to 3 of the above mentioned board are examples of such logical devices. ADC 0 to 3 all belong to the same device class ADC (analog/digital converter). I/O port 0 to 3 belong to the device class I/O port. By means of extension boards you can make your physical device drive as many logical devices as you can imagine, e.g. IR receivers, LC displays, RF receivers/transmitters, 1-wire devices, etc.

Defining one fhem module for any device class would create an unmanageable number of modules. Thus, an abstraction layer is used. You create a device class on the fly and assign it to a logical ECMD device. The class definition names the parameters of the logical device, e.g. a placeholder for the number of the ADC or port, as well as the get and set capabilities. Worked examples are to be found in the documentation of the ECMDDevice device.
Note: this module requires the Device::SerialPort or Win32::SerialPort module if the module is connected via serial Port or USB.
Define

`define <name> ECMD telnet <IPAddress:Port>`
or
`define <name> ECMD serial <SerialDevice>[<@BaudRate>]`
Defines a physical ECMD device. The keywords `telnet` or `serial` are fixed.
Examples:

`define AVRNETIO ECMD telnet 192.168.0.91:2701`
`define AVRNETIO ECMD serial /dev/ttyS0`
`define AVRNETIO ECMD serial /sev/ttyUSB0@38400`

Set

`set <name> classdef <classname> <filename>`
Creates a new device class `<classname>` for logical devices. The class definition is in the file `<filename>`. You must create the device class before you create a logical device that adheres to that definition.
Example:

`define AVRNETIO classdef /etc/fhem/ADC.classdef`

`set <name> reopen`
Closes and reopens the device. Could be handy if connection is lost and cannot be reestablished automatically.

Get

`get <name> raw <command>`
Sends the command `<command>` to the physical ECMD device `<name>` and reads the response.

Attributes

- classdefs
  A colon-separated list of <classname>=<filename>. The list is automatically updated if a class definition is added. You can directly set the attribute.

Class definition

The class definition for a logical ECMD device class is contained in a text file. The text file is made up of single lines. Empty lines and text beginning with # (hash) are ignored. Therefore make sure not to use hashes in commands.
The following commands are recognized in the device class definition:

- `params <parameter1> [<parameter2> [<parameter3> ... ]]`
  Declares the names of the named parameters that must be present in the definition of the logical ECMD device.
- `set <commandname> cmd { <perl special> }`
  Declares a new set command `<commandname>`.
- `get <commandname> cmd { <perl special> }`
  Declares a new get command `<commandname>`.
- `set <commandname> postproc { <perl command> }`
  `get <commandname> postproc { <perl command> }`
  Declares a postprocessor for the command `<commandname>`.
- `set <commandname> params <parameter1> [<parameter2> [<parameter3> ... ]]`
  `get <commandname> params <parameter1> [<parameter2> [<parameter3> ... ]]`
  Declares the names of the named parameters that must be present in the set or get command `<commandname>`. Be careful not to use a parameter name that is already used in the device definition (see `params` above).

The perl specials in the definitions of the set and get commands can contain macros. Apart from the rules outlined in the documentation of perl specials in fhem, the following rules apply:

- The character @ will be replaced with the device name. To use @ in the text itself, use the double mode (@@).
- The macro `%NAME` will expand to the device name (same as `@`).
- The macro `%<parameter>` will expand to the current value of the named parameter. This can be either a parameter from the device definition or a parameter from the set or get command.
- The macro substitution occurs before perl evaluates the expression. It is a plain text substitution.
- If in doubt what happens, run the commands with loglevel 5 and observe the log file.

Neither apply the rules outlined in the documentation of perl specials for the `<perl command>` in the postprocessor definitions nor can it contain macros. This is to avoid undesired side effects from e.g. doubling of semicolons.
The `perl command` acts on `$_`. The result of the perl command is the final result of the get or set command.

### ECMDDevice

Define

`define <name> ECMDDevice <classname> [<parameter1> [<parameter2> [<parameter3> ... ]]]`
Defines a logical ECMD device. The number of given parameters must match those given in the class definition of the device class `<classname>`.
Examples:

`define myADC ECMDDevice ADC`
`define myRelais1 ECMDDevice relais 8`

Set

`set <name> <commandname> [<parameter1> [<parameter2> [<parameter3> ... ]]]`
The number of given parameters must match those given for the set command `<commandname>` definition in the class definition.
If `set <commandname>` is invoked the perl special in curly brackets from the command definition is evaluated and the result is sent to the physical ECMD device.
Example:

`set myRelais1 on`

Get

`get <name> <commandname> [<parameter1> [<parameter2> [<parameter3> ... ]]]`
The number of given parameters must match those given for the get command `<commandname>` definition in the class definition.
If `get <commandname>` is invoked the perl special in curly brackets from the command definition is evaluated and the result is sent to the physical ECMD device. The response from the physical ECMD device is returned and the state of the logical ECMD device is updated accordingly.
Example:

`get myADC value 3`

Example 1

The following example shows how to access the ADC of the AVR-NET-IO board from Pollin with ECMD-enabled Ethersex firmware.
The class definition file `/etc/fhem/ADC.classdef` looks as follows:
`get value cmd {"adc get %channel"}
get value params channel
`
In the fhem configuration file or on the fhem command line we do the following:
`define AVRNETIO ECMD telnet 192.168.0.91:2701 # define the physical device
set AVRNETIO classdef ADC /etc/fhem/ADC.classdef # define the device class ADC
define myADC ECDMDevice ADC # define the logical device myADC with device class ADC
get myADC value 1 # retrieve the value of analog/digital converter number 1
`
The get command is evaluated as follows: `get value` has one named parameter `channel`. In the example the literal `1` is given and thus `%channel` is replaced by `1` to yield `"adc get 1"` after macro substitution. Perl evaluates this to a literal string which is send as a plain ethersex command to the AVR-NET-IO. The board returns something like `024` for the current value of analog/digital converter number 1.

Example 2

The following example shows how to switch a relais driven by pin 3 (bit mask 0x08) of I/O port 2 on for one second and then off again.
The class definition file `/etc/fhem/relais.classdef` looks as follows:
`params pinmask
set on cmd {"io set ddr 2 ff\nioset port 2 0%pinmask\nwait 1000\nio set port 2 00"}
set on postproc {s/OK;OK;OK;OK/success/; "$_" eq "success" ? "ok" : "error"; }
`
In the fhem configuration file or on the fhem command line we do the following:
`define AVRNETIO ECMD telnet 192.168.0.91:2701 # define the physical device
set AVRNETIO classdef relais /etc/fhem/relais.classdef # define the device class relais
define myRelais ECMDDevice 8 # define the logical device myRelais with pin mask 8
set myRelais on # execute the "on" command
`
The set command is evaluated as follows: `%pinmask` is replaced by `8` to yield `"io set ddr 2 ff\nioset port 2 08\nwait 1000\nio set port 2 00"` after macro substitution. Perl evaluates this to a literal string which is send as a plain ethersex command to the AVR-NET-IO line by line.
For any of the four plain ethersex commands, the AVR-NET-IO returns the string `OK`. They are concatenated and separated by semicolons. The postprocessor takes the result from `$_`, substitutes it by the string `success` if it is `OK;OK;OK;OK`, and then either returns the string `ok` or the string `error`.

### M232

Define

`define <name> M232 <m232-device>`
Define a M232 device. You can attach as many M232 devices as you like. A M232 device provides 6 analog inputs (voltage 0..5V with 10 bit resolution) and 8 bidirectional digital ports. The eighth digital port can be used as a 16 bit counter (maximum frequency 3kHz). The M232 device needs to be connected to a 25pin sub-d RS232 serial port. A USB-to-serial converter works fine if no serial port is available.
Examples:

`define m232 M232 /dev/ttyUSB2`

Set

`set <name> stop`
Stops the counter.
`set <name> start`
Resets the counter to zero and starts it.
`set <name> octet`
Sets the state of all digital ports at once, value is 0..255.
`set <name> io0..io7 0|1`
Turns digital port 0..7 off or on.

Get

`get <name> [an0..an5]`
Gets the reading of analog input 0..5 in volts.
`get <name> [io0..io7]`
Gets the state of digital ports 0..7, result is 0 or 1.
`get <name> octet`
Gets the state of all digital ports at once, result is 0..255.
`get <name> counter`
Gets the number of ticks of the counter since the last reset. The counter wraps around from 65,535 to 0 and then stops. See M232Counter for how we care about this.

Attributes

- loglevel
- model (m232)

### M232Counter

Define

`define <name> M232Counter [unit [factor [deltaunit [deltafactor]]]]`
Define at most one M232Counter for a M232 device. Defining a M232Counter will schedule an internal task, which periodically reads the status of the counter, and triggers notify/filelog commands. `unit` is the unit name, `factor` is used to calculate the reading of the counter from the number of ticks. `deltaunit` is the unit name of the counter differential per second, `deltafactor` is used to calculate the counter differential per second from the number of ticks per second.
Default values:

- unit: ticks
- factor: 1.0
- deltaunit: ticks per second
- deltafactor: 1.0

Note: the parameters in square brackets are optional. If you wish to specify an optional parameter, all preceding parameters must be specified as well.
Examples:

`define counter M232Counter turns`
`define counter M232Counter kWh 0.0008 kW 2.88` (one tick equals 1/1250th kWh)

Do not forget to start the counter (with `set .. start` for M232) or to start the counter and set the reading to a specified value (with `set ... value` for M232Counter).
To avoid issues with the tick count reaching the end point, the device's internal counter is automatically reset to 0 when the tick count is 64,000 or above and the reading basis is adjusted accordingly.

Set

`set <name> value <value>`
Sets the reading of the counter to the given value. The counter is reset and started and the offset is adjusted to value/unit.
`set <name> interval <interval>`
Sets the status polling interval in seconds to the given value. The default is 60 seconds.

Get

`get <name> status`
Gets the reading of the counter multiplied by the factor from the `define` statement. Wraparounds of the counter are accounted for by an offset (see reading `basis` in the output of the `list` statement for the device).

Attributes

- dummy
- loglevel
- model (M232Counter)

### M232Voltage

Define

`define <name> M232Voltage [an0..an5] [unit [factor]]`
Define as many M232Voltages as you like for a M232 device. Defining a M232Voltage will schedule an internal task, which reads the status of the analog input every minute, and triggers notify/filelog commands. `unit` is the unit name, `factor` is used to calibrate the reading of the analog input.
Note: the unit defaults to the string "volts", but it must be specified if you wish to set the factor, which defaults to 1.0.
Example:

`define volt M232Voltage an0`
`define brightness M232Voltage an5 lx 200.0`

Set

N/A

Get

`get <name> status`

### xxLG7000

Define

`define <name> xxLG7000 <serial-device>`
Defines a serial link to a TV set of LG's xxLG70yy (e. g. 47LG7000) series and similar TV sets from LG. As of January 2010, the following TV sets should be compatible:

- `xxLG7000`, e. g. 47LG7000 (tested)
- `xxPG7000`, e. g. 50PG7000 (same Manual as 47LG7000 ;))
- `PS3000/6000/7000/8000 series` (according to LG brochure; no liabilities assumed)
- `PQ3000/6000 series` (see PS3000)
- `LU4000/5000 series` (not LU7000; see PS3000)
- `LH2000/3000/4000/5000 series` (see PS3000)
- `SL9500/9000/8000 series` (see PS3000)

These TV sets feature a serial connector which can officially be used to control the TV set (see your Onwer's Manual, there's an Appendix labelled "External Control Device setup", referening to cabling and command set). The xxLG7000 module is the FHEM module to actually utilize this. (BTW, those TVs run Linux internally ;))
To exercise control over your TV set, use the LGTV module and bind it ("attr <LGTV-name> IODev <xxLG7000-name>") to xxLG7000.
Examples:

`define myLG7k xxLG7000 /dev/ttyUSB1`

Set

Not used, nothing to set directly.

Get

Not used, nothing to get directly.

Attributes

- loglevel
- SetID (1, 2, ...; see your TV's Owner's Manual how to set it. Defaults to 1 if unset.)

### LGTV

Define

`define <name> LGTV`
This module is expected to work with xxLG7000 as it's IODev. With LGTV and a compatible hardware module (currently, there's only xxLG7000), you are able to power your TV set on and off, query it's power state, select the input (AV, RGB, Composites, analogue TV, DVB-T, HDMI) or mute/unmute the volume.
Defining a LGTV device will schedule an internal task, which periodically reads the status of the TV set (power state; if power is on, query the selected input) and triggers notify/filelog commands.
Example:

`define 47LG7000 LGTV`
`attr 47LG7000 IODev myLG7k`

Set

`set <name> <what> <value>`
Currently, the following commands are defined; not all may be available on a given TV set. An error messages should be recorded if e. g. the input in question is not usable.

    power on
    power off
    input AV1
    input AV2
    input AV3
    input AV3
    input Component
    input RGB
    input HDMI1
    input HDMI2
    input HDMI3
    input HDMI4
    input DVBT
    input PAL
    audio mute
    audio normal

Get

`get <name> <what>`
Currently, the following commands are defined; not all may be available on a given TV set. An error messages should be recorded if e. g. the input in question is not usable.

    power
    input
    audio

Attributes

- dummy
- loglevel

Implementator's note

The commands listed above are send 1:1 to the underlying IODev (e. g. xxLG7000); that IODev is responsible for translation into whatever means to invoke the function on the TV. It is my hope that other's will adopt this idea and write compatible low level drivers for other TV sets, to make this module (even ;)) more useful.

### OREGON

The OREGON module interprets Oregon sensor messages received by a RFXCOM receiver. You need to define a RFXCOM receiver first. See RFXCOM.
Define

`define <name> OREGON <deviceid>`
<deviceid> is the device identifier of the Oregon sensor. It consists of the sensors name and a one byte hex string (00-ff) that identifies the sensor. The define statement with the deviceid is generated automatically by autocreate. The following sensor names are used: BTHR918, BTHR918N, PCR800 RGR918, RTGR328N, THN132N, THGR228N, THGR328N, THGR918, THR128, THWR288A, THGR810, UV138, UVN800, WGR918, WGR800, WTGR800_A, WTGR800_T.
The one byte hex string is generated by the Oregon sensor when is it powered on. The value seems to be randomly generated. This has the advantage that you may use more than one Oregon sensor of the same type even if it has no switch to set a sensor id. For exampple the author uses three BTHR918 sensors at the same time. All have different deviceids. The drawback is that the deviceid changes after changing batteries.
Example:
`define Kaminzimmer OREGON BTHR918N_ab`

Set

### OWFS

OWFS is a suite of programs that designed to make the 1-wire bus and its devices easily accessible. The underlying priciple is to create a virtual filesystem, with the unique ID being the directory, and the individual properties of the device are represented as simple files that can be read and written.
Note: You need the owperl module from http://owfs.org/.
Define

`define <name> OWFS <owserver-ip:port> <model> [<id>]`
Define a 1-wire device to communicate with an OWFS-Server.
`<owserver-ip:port>`

IP-address:port from OW-Server.

`<model>`

Define the type of the input device. Currently supportet: `DS1420, DS9097 (for passive Adapter)`

`<id>`

Corresponding to the id of the input device. Only for active Adapter.

Note:
If the `owserver-ip:port` is called `none`, then no device will be opened, so you can experiment without hardware attached.
Example:

`#define an active Adapter:
define DS9490R OWFS 127.0.0.1:4304 DS1420 93302D000000`

`#define a passive Adapter:
define DS9097 OWFS 127.0.0.1:4304 DS9097`

Set

  The entire 64-bit unique ID. address starts with the family code.
  Given as upper case hexidecimal digits (0-9A-F).
- `crc8` (read-only)
  The 8-bit error correction portion. Uses cyclic redundancy check. Computed from the preceeding 56 bits of the unique ID number.
  Given as upper case hexidecimal digits (0-9A-F).
- `family` (read-only)
  The 8-bit family code. Unique to each type of device.
  Given as upper case hexidecimal digits (0-9A-F).
- `id` (read-only)
  The 48-bit middle portion of the unique ID number. Does not include the family code or CRC.
  Given as upper case hexidecimal digits (0-9A-F).
- `locator` (read-only)
  Uses an extension of the 1-wire design from iButtonLink company that associated 1-wire physical connections with a unique 1-wire code. If the connection is behind a Link Locator the locator will show a unique 8-byte number (16 character hexidecimal) starting with family code FE.
  If no Link Locator is between the device and the master, the locator field will be all FF.
- `present` (read-only)
  Is the device currently present on the 1-wire bus?
- `type` (read-only)
  Part name assigned by Dallas Semi. E.g. DS2401 Alternative packaging (iButton vs chip) will not be distiguished.

### RFXCOM

RFXCOM sells RF receivers and transmitters for a variety of protocols. The 433.92MHz receivers supports many protocols like Oregon Scientific weather sensors, RFXMeter devices, X10 security and lightning devices adn others. This module supports receiving messages for the USB attached receivers (see http://www.rfxcom.com/receivers.htm). For testing purposes you may also use the LAN based receivers. However the code for LAN access is not fault tolerant. I recommend to use the USB attached receiver. Currently the following parser modules are implemented: 41_OREGON.pm (see device OREGON): Process messages Oregon Scientific weather sensors. See http://www.rfxcom.com/oregon.htm of Oregon Scientific weather sensors that could be received by the RFXCOM receivers. See http://www.rfxcom.com/sensors.htm. Until now the following Oregon Scientific weather sensors have been tested successfully: BTHR918N, THGR810, THR128, THWR288A, PCR800, WTGR800. It will probably work with many other Oregon sensors supported by RFXCOM receivers. Please give feedback if you use other sensors. 42_RFXMETER.pm (see device RFXMETER): Process RFXCOM RFXMeter devices. 43_RFXX10REC.pm (see device RFXX10REC): Process X10 security and X10 lightning devices. 44_RFXELSE.pm: Process and display all other messages. This module shows you messages that could not be handled by the other modules. It is useful to see RF receiption problems. Note: this module requires the Device::SerialPort or Win32::SerialPort module if the devices is connected via USB or a serial port. Define `define <name> RFXCOM <device> [noinit]` USB-connected (80002): <device> specifies the USB port to communicate with the RFXCOM receiver. Normally on Linux the device will be named /dev/ttyUSBx, where x is a number. For example /dev/ttyUSB0. Example: `define RFXCOMUSB RFXCOM /dev/ttyUSB0` Network-connected devices: <device> specifies the host:port of the device. E.g. 192.168.1.5:10001 noninit is optional and issues that the RFXCOM device should not be initialized. This is useful if you share a RFXCOM device. It is also useful for testing to simulate a RFXCOM receiver via netcat. Example: `define RFXCOMTCP RFXCOM 192.168.1.5:10001 `define RFXCOMTCP2 RFXCOM 192.168.1.121:10001 noinit``

### RFXMETER

The RFXMETER module interprets RFXCOM RFXMeter messages received by a RFXCOM receiver. You need to define an RFXCOM receiver first. See the RFXCOM.
Define

`define <name> RFXMETER <deviceid> [<scalefactor>] [<unitname>]`
<deviceid> is the device identifier of the RFXMeter sensor and is a one byte hexstring (00-ff).
<scalefactor> is an optional scaling factor. It is multiplied to the value that is received from the RFXmeter sensor.
<unitname> is an optional string that describes the value units. It is added to the Reading generated to describe the values.
Example:
`define RFXWater RFXMETER 00 0.5 ltr`
`define RFXPower RFXMETER 01 0.001 kwh`
`define RFXGas RFXMETER 02 0.01 cu_m`

### RFXX10REC

The RFXX10REC module interprets X10 security and X10 lightning messages received by a RFXCOM RF receiver. Reported also to work with KlikAanKlikUit. You need to define an RFXCOM receiver first. See RFXCOM.
Define

`define <name> RFXX10REC <type> <deviceid> <devicelog> [<deviceid> <devicelog>]`
`<type>`

specifies the type of the X10 device:
X10 security devices:

- `ds10a` (X10 security ds10a Door/Window Sensor or compatible devices. This device type reports the status of the switch [Open/Closed], status of the delay switch [min|max]], and battery status [ok|low].)
- `ms10a` (X10 security ms10a motion sensor. This device type reports the status of motion sensor [normal|alert] and battery status [ok|low].))
- `sd90` (Marmitek sd90 smoke detector. This device type reports the status of the smoke detector [normal|alert] and battery status [ok|low].)
- `kr18` (X10 security remote control. Report the Reading "Security" with values [Arm|Disarm], "ButtonA" and "ButtonB" with values [on|off] )

X10 lightning devices:

- `ms14a` (X10 motion sensor. Reports [normal|alert] on the first deviceid (motion sensor) and [on|off] for the second deviceid (light sensor))
- `x10` (All other x10 devices. Report [on|off] on both deviceids.)

`<deviceid>`

specifies the first device id of the device. X10 security have a a 16-Bit device id which has to be written as a hex-string (example "5a54"). A X10 lightning device has a house code A..P followed by a unitcode 1..16 (example "B1").

`<devicelog>`

is the name of the Reading used to report. Suggested: "Window" or "Door" for ds10a, "motion" for motion sensors, "Smoke" for sd90.

`<deviceid2>`

is optional and specifies the second device id of the device if it exists. For example sd90 smoke sensors can be configured to report two device ids. ms14a motion sensors report motion status on the first deviceid and the status of the light sensor on the second deviceid.

`<devicelog2>`

is optional for the name used for the Reading of `<deviceid2>`.

Example:
`define livingroom_window RFXX10REC ds10a 72cd Window`
`define motion_sensor1 RFXX10REC ms10a 55c6 motion`
`define smoke_sensor1 RFXX10REC sd90 54d3 Smoke 54d3 Smoketest`

### WS2000

Define

`define <name> WS2000 <device_to_connect>`
Define a WS2000 series raw receiver device sold by ELV. Details see here. Unlike 86_FS10.pm it will handle the complete device communication itself and doesnt require an external program. For this reason you can now use this also on windows.
This Device will be usually connect to a serial port, but you can also define a raw network redirector like lantronix XPORT(TM).
Note: Currently this device does not support a "set" function

### WS3600

Define

`define <name> WS3600 </path/to/fetch3600>`
Define a WS3600 series weather station (Europe Supplies, technotrade, etc; refer to Wetterstationen.info (german) for details on this model); the station is queried by means of an external program, fetch3600. It talks to the attached weather station (several WS do supply an RS323 interface but seem to use some kind of "morse code" on the RTS, CTS wires instead of using propper serial communication (RX, TX); it's no use to recode that crap into FHEM when there is a stable package of tools to talk to the station available: open3600) and delivers the current readings line by line as reading-value-pairs. These are read in and translated into more readable names for FHEM by the module WS3600.pm.
As the WS3600 is rather similar to the WS2300 and open3600 basically is a modified offspring of open2300, by exchanging the /path/to/fetch3600 with /path/to/fetch2300 this module should be able to handle the WS2300 was well.
Currently, it is expected that the WS is attached to the local computer and fetch3600 is run locally. Basically the executable called needs to supply on stdout an output similar to what fetch3600 returns; how to implement a "networked setup" is left as an excercise to the reader.
For the records, this is an output of fetch3600:

There is no expectation on the readings received from the fetch3600 binary; so, in essence, if you have a similar setup (unsupported, attached weather station and a means to get it's reading into an output similar to above's), you should be able to use WS3600.pm with a custom written script to interface FHEM with your station as well. WS3600.pm only recognizes the above readings (and translates these into, e. g., `Temp-inside` for `Ti` for use within FHEM), other lines are silently dropped on the floor.
fetch3600 is available as binary for the Windows OS as well, but I haven't tested operation under that OS, use it at your own risk and you mileage may vary ...
Note: Currently this device does not support a "set" function nor anything to "get". The later would be possible to implement if neccessary, though.
Implementation of WS3600.pm tries to be nice, that is it reads from the pipe only non-blocking (== if there is data), so it should be safe even to use it via ssh or a netcat-pipe over the Internet, but this, as well, has not been tested yet.

### SISPM

Define

`define <name> SISPM </path/to/sispmctl>`
PLEASE NOTE: This module is still work in progess; please treat it as such. (That is, don't but your central heating on SISPM in a cold winter just yet ;))
Further tests should be done regarding the interaction between "set" commands and the sheduled status reading. (Testing with FIFOs seems as if it's working without blocking nor interference, but that's on a mostly unloaded, fast system.)
When using multiple SIS PMs on one host, sispmctl up to and including V 2.7 has a bug:

Defines a path to the program "sispmctl", which is used to control (locally attached) "Silver Shield Power Manager" devices. Usually these are connected to the local computer via USB, more than one "sispm" device per computer is supported. (Please note that, due to neglections in their USB driver, AVM's Fritz!Box 7170 (and derivates, like Deutsche Telekom's Speedport W901V) is not able to talk to these devices ...) The communication between FHEM and the Power Manager device is done by using the open source sispmctl program. Thus, for the time being, THIS functionality is only available running FHEM on Linux (or any other platform where you can get the sispmctl program compiled and running). On the bright side: by interfacing via commandline, it is possible to define multiple SISPM devices, e. g. with a wrapper that does execute sispmctl on a remote (Linux) system. And: sispmctl runs happily on Marvells SheevaPlug ;) Please note: if you're not running FHEM as root, you most likely have to make sispmctl setuid root (`chmod 4755 /path/to/sispmctl`) or fiddle with udev so that the devices of the Power Manager are owned by the user running FHEM. After defining a SISPM device, a first test is done, identifying attached PMs. If this succeeds, an internal task is scheduled to read the status every 30 seconds. (Reason being that someone else could have switched sockets externally to FHEM.) To actually control any power sockets, you need to define a SIS_PMS device ;) If autocreate is enabled, those should be autocreated for your convenience as soon as the first scan took place (30 seconds after the define). Implementation of SISPM.pm tries to be nice, that is it reads from the pipe only non-blocking (== if there is data), so it should be safe even to use it via ssh or a netcat-pipe over the Internet, but this, as well, has not been tested extensively yet.

### SIS_PMS

This module is responsible for handling the actual sockets (power on, power off, toggle) on a "Silver Shield Power Manager", see SISPM for how to define access to one (SIS_PMS stands for "Silver Shield Power Manager Socket").
Define

`define <name> SIS_PMS <serial> <socket>`
To securely distinguish multiple attached Power Manager devices, the serial number of those is used. You get these with "sispmctl -s" - or just let autocreate define the sockets attached for you.

- `<serial>` is the serial number of the Power Manager device, see above.
- `<socket>` is a number between 1 and 4 (for a 4 socket model)

Examples:

`define lamp SIS_PMS 01:02:03:04:05 1`
`define otherlamp SIS_PMS 01:02:03:04:05 3`
`define tv SIS_PMS 01:01:38:44:55 1`

Set

`set <name> <value> [<time>]`
where `value` is one of:

        off
        on
        toggle
        on-till           # Special, see the note
        off-till          # Special, see the note

Examples:

`set lamp on`
`set lamp1,lamp2,lamp3 on`
`set lamp1-lamp3 on`
`set hql_lamp on-till 18:45`

Notes:

- As an external program is used, a noticeable delay may occur.
- *-till requires an absolute time in the "at" format (HH:MM:SS, HH:MM or { <perl code> }, where the perl-code returns a time specification). If the current time is greater than the specified time, then the command is ignored, else an "on" or "off" command, respectively, is generated, and for the given time an "off"/"on" command is scheduleld via the at command.

### IPWE

Define

`define <name> IPWE <hostname> [<delay>]`
Define a IPWE network attached weather data receiver device sold by ELV. Details see here. It's intended to receive the same sensors as WS300 (8 T/H-Sensors and one kombi sensor), but can be accessed via http and telnet.
For unknown reason, my try to use the telnet interface was not working neither with raw sockets nor with Net::Telnet module. Therefore i choosed here the "easy" way to simple readout the http page and extract all data from the offered table. For this reason this module doesnt contain any option to configure this device.
Note: You should give your sensors a name within the web interface, once they a received the first time.
To extract a single sensor simply match for this name or sensor id
Attributes:

- `delay`: seconds between read accesses(default 300s)

Example:

`define ipwe IPWE ipwe1 120`

`attr ipwe delay 600` : 10min between readouts

Set

### ITACH_RELAY

Note: this module needs the Net::Telnet module.
Define

`define <name> ITACH_RELAY <ip-address> <port>`
Defines an Global Cache iTach Relay device (Box with 3 relays) via its ip address.
Examples:

`define motor1 ITACH_RELAY 192.168.8.200 1`

Set

`set <name> <value>`
where `value` is one of:

        off
        on
        toggle

Examples:

`set motor1 on`

Notes:

- Toggle is special implemented. List name returns "on" or "off" even after a toggle command

### USBWX

The USBWX module interprets the messages received by the ELV USB-WDE1 weather receiver. This receiver is compaptible with the following ELV sensors: KS200/KS300, S300IA, S300TH, ASH2200, PS50. It also known to work with Conrad weather sensors KS555, S555TH and ASH555.
This module was tested with ELV S300TH, ELV ASH2200, ELV KS300, Conrad S555TH and Conrad KS555.
Readings and STATE of temperature/humidity sensors are compatible with the CUL_WS module. For KS300/KS555 sensors STATE is compatible with the KS300 module. The module is integrated into autocreate to generate the appropriate filelogs and weblinks automatically.
Note: this module requires the Device::SerialPort or Win32::SerialPort module if the devices is connected via USB or a serial port.
Define

`define <name> USBWX <serial device>`
Defines USB-WDE1 attached via usb.
`define <name> USBWX <code> [corr1...corr4]`
<code> is the code which must be set on the sensor. Valid values are 1 through 8.
9 is used as the sensor id of the ks300 sensor.
corr1..corr4 are up to 4 numerical correction factors, which will be added to the respective value to calibrate the device. Note: rain-values will be multiplied and not added to the correction factor.
Example:

        define USBWDE1 USBWX /dev/ttyUSB0
        define USBWX_1 USBWX 1
        define USBWX_livingroom USBWX 2
        define USBWX_ks300 USBWX 9

### TCM

The TCM module serves an USB or TCP/IP connected TCM120 or TCM310 EnOcean Transceiver module. These are mostly packaged together with a serial to USB chip and an antenna, e.g. the BSC BOR contains the TCM120, the EUL from busware contains a TCM310. See also the datasheet available from www.enocean.com.
As the TCM120 and the TCM310 speak completely different protocols, this module implements 2 drivers in one. It is the "physical" part for the EnOcean module.
Define

`define <name> TCM [120|310] <device>`
First you have to specify the type of the EnOcean Transceiver Chip , i.e either 120 for the TCM120 or 310 for the TCM310.
`device` can take the same parameters (@baudrate, @directio, TCP/IP, none) like the CUL, but you probably have to specify the baudrate: the TCM120 should be opened with 9600 Baud, the TCM310 with 57600 baud. Example:

`define BscBor TCM 120 /dev/ttyACM0@9600
define TCM310 TCM 310 /dev/ttyACM0@57600
`

### weblink

Define

`define <name> weblink [link|fileplot|image|iframe] <argument>`
This is a placeholder used with webpgm2 to be able to integrate links into it, and to be able to put more than one gnuplot/SVG picture on one page. It has no set or get methods. Examples:

`define homepage weblink link http://www.fhem.de`
`define webcam_picture weblink image http://w.x.y.z/current.jpg`
`define interactive_webcam weblink iframe http://w.x.y.z/webcam.cgi`
`define MyPlot weblink fileplot <logdevice>:<gnuplot-file>:<logfile>`

Notes:

- Normally you won't have to define fileplot weblinks manually, as FHEMWEB makes it easy for you, just plot a logfile (see logtype) and convert it to weblink. Now you can group these weblinks by putting them into rooms. If you convert the current logfile to a weblink, it will always refer to the current file, even if its name changes regularly (and not the one you originally specified).

- fixedrange
- plotsize
- plotmode
- label
  Double-Colon separated list of values. The values will be used to replace <L#> type of strings in the .gplot file, with # beginning at 1 (<L1>, <L2>, etc.). Each value will be evaluated as a perl expression, so you have access e.g. to the Value functions.
  If the plotmode is gnuplot-scroll or SVG, you can also use the min, max, avg, cnt, sum, lastv (last value) and lastd (last date) values of the individual curves, by accessing the corresponding values from the data hash, see the example below:
  - Fixed text for the right and left axis:
    - Fhem config:
      attr wl_1 label "Temperature"::"Humidity"
    - .gplot file entry:
      set ylabel <L1>
      set y2label <L2>
  - Title with maximum and current values of the 1st curve (FileLog)
    - Fhem config:
      attr wl_1 label "Max $data{max1}, Current $data{currval1}"
    - .gplot file entry:
      set title <L1>
- title
  A special form of label (see above), which replaces the string <TL> in the .gplot file. It defaults to the filename of the logfile.

### FHEM2FHEM

FHEM2FHEM is a helper module to connect separate fhem installations.
Define

`define <name> FHEM2FHEM <host:portnr> [LOG:regexp|RAW:devicename]`
Connect to the remote fhem on host. portnr is the global port attribute of the remote fhem. The next parameter specifies the connection type:

- LOG
  Using this type you will receive all events generated by the remote fhem, just like when using the inform on command, and you can use these events just like any local event for FileLog or notify. The regexp will prefilter the events distributed locally, for the syntax see the notify definition.
  Drawbacks: the remote devices wont be created locally, so list wont show them and it is not possible to manipulate them from the local fhem. It is possible to create a device with the same name on both fhem instances, but if both of them receive the same event (e.g. because both of them have a CUL attached), then all associated FileLogs/notifys will be triggered twice.
- RAW
  By using this type the local fhem will receive raw events from the remote fhem device devicename, just like if it would be attached to the local fhem. Drawback: only devices using the Dispatch function (CUL, FHZ, CM11, SISPM, RFXCOM, TCM, TUL) generate raw messages.
  devicename must exist on the local fhem server too with the same name and same type as the remote device, but usually with the device-node "none", so it is only a dummy device. All necessary attributes (e.g. rfmode if the remote CUL is in HomeMatic mode) must also be set for the local device.

Examples:

`define ds1 FHEM2FHEM 192.168.0.1:7072 LOG:.*`
`define ds2 FHEM2FHEM 192.168.0.1:7072 RAW:CUL`

### FHEMWEB

FHEMWEB is the builtin web-frontend (webpgm2). It implements a simple web server (optionally with Basic-Auth and HTTPS), so no additional program is needed.
Define

`define <name> FHEMWEB <tcp-portnr> [global]`
Enable the webfrontend on port <tcp-portnr>. If global is specified, then requests from all interfaces (not only localhost / 127.0.0.1) are serviced.
To enable listening on IPV6 see the comments here.
Feature: http://host:port/fhem/icons/<devicename> will return the icon associated with the current status of <devicename>.

Set

N/A

Get

N/A

Attributes

- webname
  Path after the http://hostname:port/ specification. Defaults to fhem, i.e the default http address is http://localhost:8083/fhem
- refresh
  If set, a http-equiv="refresh" entry will be genererated with the given argument (i.e. the browser will reload the page after the given seconds).
- plotmode
  Specifies how to generate the plots:
  - gnuplot
    Call the gnuplot script with each logfile. The filename specification of the FileLog device will determine what is in the plot. The data is converted into an image on the backend with gnuplot.
  - gnuplot-scroll
    Fhemweb will offer zoom and scroll buttons in order to navigate in the current logfile, i.e. you can select just a part of the data to be displayed. The more data is contained in a single logfile, the easier you can navigate. The recommendation is to store the data for a whole year in one logfile. The data is converted into an image on the backend with gnuplot.
  - SVG
    The same scrolling as with gnuplot scroll, but the data is sent as an SVG script to the frontend, which will compute the image: no need for gnuplot on the backend. This is the default. Note: SVG is supported on the Android platform by Opera/Firefox and the Internet Explorer before 9 needs a plugin.
  See also the attribute fixedrange. Note: for gnuplot & gnuplot-scroll mode the gnuplot output is redirected to the file gnuplot.err in the /tmp directory
- plotsize
  the default size of the plot, in pixels, separated by comma: width,height. You can set individual sizes by setting the plotsize of the weblink. Default is 800,160 for desktop, and 480,160 for smallscreen.
- fixedrange
  Can be applied to weblink devices (FHEMWEB).
  Contains two time specs in the form YYYY-MM-DD separated by a space. In plotmode gnuplot-scroll or SVG the given time-range will be used, and no scrolling for this weblinks will be possible. Needed e.g. for looking at last-years data without scrolling.
  If the value is one of day, week, month, year than set the zoom level for this weblink independently of the user specified zoom-level. This is useful for pages with multiple plots: one of the plots is best viewed in with the default (day) zoom, the other one with a week zoom.
- smallscreen, touchpad
  Optimize for small screen size (i.e. smartphones) or for touchpad devices (i.e. tablets)
  Note: The default configuration installed with make install-pgm2 installs 2 FHEMWEB instances: port 8083 for desktop browsers and port 8084 for smallscreen browsers, both using SVG rendering. On Android SVG is supported by Opera/Firefox.
  WebApp suppport if specifying one of the above options: After viewing the site on the iPhone or iPad in Safari, add it to the home-screen to get full-screen support.
- plotfork
  If set, generate the logs in a parallel process. Note: do not use it on Windows and on systems with small memory foorprint.
- basicAuth, basicAuthMsg
  request a username/password authentication for access. You have to set the basicAuth attribute to the Base64 encoded value of <user>:<password>, e.g.:
  # Calculate first the encoded string with the commandline program
  $ echo -n fhemuser:secret | base64
  ZmhlbXVzZXI6c2VjcmV0
  fhem.cfg:
  attr WEB basicAuth ZmhlbXVzZXI6c2VjcmV0
  You can of course use other means of base64 encoding, e.g. online Base64 encoders. If basicAuthMsg is set, it will be displayed in the popup window when requesting the username/password.
- HTTPS
  use HTTPS instead of HTTP. This feature requires the perl module IO::Socket::SSL, to be installed with cpan -i IO::Socket::SSL or apt-get install libio-socket-ssl-perl; the OSX perl already has this module.
  A local certificate has to be generated into a directory called certs, this directory must be in the working directory (pwd) of fhem, which is not necessarily the modpath directory. To generate it:
  mkdir certs
  cd certs
  openssl req -new -x509 -nodes -out server-cert.pem -days 3650 -keyout server-key.pem
- stylesheetPrefix
  prefix for the files style.css, svg_style.css and svg_defs.svg. If the file with the prefix is missing, the default file (without prefix) will be used. These files have to be placed into the FHEM directory, and can be selected directly from the "Select style" FHEMWEB menu entry. Example:
  attr WEB stylesheetPrefix dark
  Referenced files:
  darksvg_defs.svg
  darksvg_style.css
  darkstyle.css
- hiddenroom
  Komma separated list of rooms to "hide", i.e. not to show. Special values are input and detail, in which case no input areas or link to the detailed views are shown (although they still can be addressed through url manipulation). The list can also contain values from the additional "Howto/Wiki/FAQ" block.
- longpoll
  Affects devices states in the room overview only.
  In this mode status update is refreshed more or less instantaneously, and state change (on/off only) is done without requesting a complete refresh from the server.
- webCmd
  Colon separated list of commands to be shown in the room overview for a certain device. Example:
  attr lamp webCmd on:off:on-for-timer 10
  On smallscreen devices only the first value is accessible.

### at

Start an arbitrary fhem.pl command at a later time.
Define

`define <name> at <timespec> <command>`
`<timespec>` format: [+][*{N}]<timedet>

The optional `+` indicates that the specification is relative(i.e. it will be added to the current time).
The optional `*` indicates that the command should be executed repeatedly.
The optional `{N}` after the * indicates,that the command should be repeated N-times only.
<timedet> is either HH:MM, HH:MM:SS or {perlfunc()}, where perlfunc must return a HH:MM or HH:MM:SS date.

Examples:

        # absolute ones:
        define a1 at 17:00:00 set lamp on                            # fhem command
        define a2 at 17:00:00 { Log 1, "Teatime" }                   # Perl command
        define a3 at 17:00:00 "/bin/echo "Teatime" > /dev/console"   # shell command
        define a4 at *17:00:00 set lamp on                           # every day

        # relative ones
        define a5 at +00:00:10 set lamp on                  # switch on in 10 seconds
        define a6 at +00:00:02 set lamp on-for-timer 1      # Blink once in 2 seconds
        define a7 at +*{3}00:00:02 set lamp on-for-timer 1  # Blink 3 times

        # Blink 3 times if the piri sends a command
        define n1 notify piri:on.* define a8 at +*{3}00:00:02 set lamp on-for-timer 1

        # Switch the lamp on from sunset to 11 PM
        define a9 at +*{sunset_rel()} set lamp on
        define a10 at *23:00:00 set lamp off

        # More elegant version, works for sunset > 23:00 too
        define a11 at +*{sunset_rel()} set lamp on-till 23:00

        # Only do this on weekend
        define a12 at +*{sunset_rel()} { fhem("set lamp on-till 23:00") if($we) }

        # Switch lamp1 and lamp2 on from 7:00 till 10 minutes after sunrise
        define a13 at *07:00 set lamp1,lamp2 on-till {sunrise(+600)}

        # Switch the lamp off 2 minutes after sunrise each day
        define a14 at +{sunrise(+120)} set lamp on

        # Switch lamp1 on at sunset, not before 18:00 and not after 21:00
        define a15 at *{sunset(0,"18:00","21:00")} set lamp1 on

Notes:

- if no `*` is specified, then a command will be executed only once, and then the `at` entry will be deleted. In this case the command will be saved to the statefile (as it considered volatile, i.e. entered by cronjob) and not to the configfile (see the save command.)
- if the current time is greater than the time specified, then the command will be executed tomorrow.
- For even more complex date handling you either have to call fhem from cron or filter the date in a perl expression, see the last example and the section Perl special.

Attributes

- disable
  Can be applied to at/watchdog/notify/FileLog devices.
  Disables the corresponding at/notify or FileLog device. Note: If applied to an at, the command will not be executed, but the next time will be computed.
- skip_next
  Used for at commands: skip the execution of the command the next time.

### autocreate

Automatically create not yet defined fhem devices upon reception of a message generated by this device. Note: devices which are polled (like the EMEM/EMWZ accessed through the EM1010PC) will NOT be automatically created.
Define

`define <name> autocreate`

It makes no sense to create more than one instance of this module. By defining an instance, the global attribute autoload_undefined_devices is set, so that modules for unknnown devices are automatically loaded. The autocreate module intercepts the UNDEFINED event generated by each module, creates a device and optionally also FileLog and weblink entries.
Note 1: devices will be created with a unique name, which contains the type and a unique id for this type. When renaming the device, the automatically created filelog and weblink devices will also be renamed.
Note 2: you can disable the automatic creation by setting the disable attribute, in this case only the rename hook is active, and you can use the createlog command to add FileLog and weblink to an already defined device.

Example:

        define autocreate autocreate
        attr autocreate autosave
        attr autocreate device_room %TYPE
        attr autocreate filelog test2/log/%NAME-%Y.log
        attr autocreate weblink
        attr autocreate weblink_room Plots

Set

N/A

Get

N/A

Attributes

- autosave
  After creating a device, automatically save the config file with the command save command.
- device_room
  "Put" the newly created device in this room. The name can contain the wildcards %TYPE and %NAME, see the example above.
- filelog
  Create a filelog associated with the device. The filename can contain the wildcards %TYPE and %NAME, see the example above. The filelog will be "put" in the same room as the device.
- weblink
  Create a weblink associated with the device/filelog.
- weblink_room
  "Put" the newly weblink in this room. The name can contain the wildcards %TYPE and %NAME, see the example above.
- disable
- ignoreTypes
  This is a regexp, to ignore certain devices, e.g. you neighbours FHT. You can specify more than one, with usual regexp syntax, e.g.
  attr autocreate ignoreTypes CUL_HOERMANN.*|FHT_1234|CUL_WS_7

createlog

Use this command to manually add a FileLog and a weblink to an existing device. E.g. if a HomeMatic device is created automatically by something else then a pairing message, the model is unknown, so no plots will be generated. You can set the model/subtype attribute manually, and then call createlog to add the corresponding logs.

### average

Compute additional average_day and average_month values.
Define

`define <name> average <regexp>`

The syntax for <regexp> is the same as the regexp for notify.
If it matches, and the event is of the form "eventname number", then this module computes the daily and monthly average, and generates an event of the form

<device> <eventname>_avg_day: <computed_average>

and

<device> <eventname>_avg_month: <computed_average>

at the beginning of the next day or month respectively.
The current average and the cumulated values are stored in the device readings.

Example:

        # Compute the average for the temperature events of the ws1 device
        define avg_temp_ws1 average ws1:temperature.*

        # Compute the average for each temperature event
        define avg_temp_ws1 average .*:temperature.*

        # Compute the average for all temperature and humidity events
        # Events:
        # ws1 temperature: 22.3
        # ws1 humidity: 67.4
        define avg_temp_ws1 average .*:(temperature|humidity).*

        # Hunt only for the humidity: take the value from the first
        # parenthesis ($1 in perl regexp) if it is a number
        # Event: ws1 T: 52.3  H: 67.4
        define avg_temp_ws1 average ws1:.*H:.([-\d\.]+)

### holiday

Define

`define <name> holiday`
Define a set of holidays. The module will try to open the file <name>.holiday in the modpath/FHEM directory. If an entry in the holiday file matches the current day, then the STATE of this holiday instance displayed in the list command will be set to the holiday, else the state is set to the text none. Most probably you'll want to query this value in some perl script: see Value() in the perl section or the global attribute holiday2we.
The file will be reread once every night, to compute the value for the current day, and by each get command (see below).
Holiday file definition:
The file may contain comments (beginning with #) or empty lines. Significant lines begin with a number (type) and contain some space separated words, depending on the type. The different types are:

- 1
  Exact date. Arguments: <MM-DD> <holiday-name>
  Exampe: 1 12-24 Christmas
- 2
  Easter-dependent date. Arguments: <day-offset> <holiday-name>. The offset is counted from Easter-Sunday.
  Exampe: 2 1 Easter-Monday
  Sidenote: You can check the easter date with: fhem> { join("-", western_easter(2011)) }
- 3
  Month dependent date. Arguments: <nth> <weekday> <month <holiday-name>.
  Examples:
  3 1 Mon 05 First Monday In May
  3 2 Mon 05 Second Monday In May
  3 -1 Mon 05 Last Monday In May
  3 0 Mon 05 Each Monday In May
- 4
  Interval. Arguments: <MM-DD> <MM-DD> <holiday-name> .
  Example:
  4 01-06 31-06 Summer holiday
- 5
  Date relative, weekday fixed holiday. Arguments: <nth> <weekday> <month> <day> < holiday-name>
  Note that while +0 or -0 as offsets are not forbidden, their behaviour is undefined in the sense that it might change without notice.
  Examples:
  5 -1 Wed 11 23 Buss und Bettag (first Wednesday before Nov, 23rd)
  5 1 Mon 01 31 First Monday after Jan, 31st (1st Monday in February)

See also he.holiday in the contrib directory for official holidays in the german country of Hessen, and by.holiday for the Bavarian definition.

### notify

Define

`define <name> notify <pattern> <command>`
Execute a command when received an event for the definition `<pattern>`. If <command> is enclosed in {}, then it is a perl expression, if it is enclosed in "", then it is a shell command, else it is a "plain" fhem.pl command (chain). See the trigger command for testing it. Examples:

`define b3lampV1 notify btn3 set lamp %`
`define b3lampV2 notify btn3 { fhem "set lamp %" }`
`define b3lampV3 notify btn3 "/usr/local/bin/setlamp "%""`
`define b3lampV3 notify btn3 set lamp1 %;;set lamp2 %`
`define wzMessLg notify wz:measured.* "/usr/local/bin/logfht @ "%""`
`define LogUndef notify global:UNDEFINED.* "send-me-mail.sh "%""`

Notes:

- The character `%` will be replaced with the received event, e.g. with `on` or `off` or `measured-temp: 21.7 (Celsius)`
  It is advisable to put the `%` into double quotes, else the shell may get a syntax error.
- The character `@` will be replaced with the device name.
- To use % or @ in the text itself, use the double mode (%% or @@).
- Instead of `%` and `@`, the parameters `%EVENT` (same as `%`), `%NAME` (same as `@`) and `%TYPE` (contains the device type, e.g. `FHT`) can be used. The space separated event "parts" are available as %EVTPART0, %EVTPART1, etc. A single `%` looses its special meaning if any of these parameters appears in the definition.
- `<pattern>` may also be a compound of `definition:event` to filter for events.
- `<pattern>` must completely (!) match either the device name, or the compound of the device name and the event. The event is either the string you see in the list output in paranthesis after the device name, or the string you see when you do a detailed list of the device.
- To use database logging, copy the file contrib/91_DbLog.pm into your modules directory, and change the $dbconn parameter in the file.
- Following special events will be generated for the device "global"
  - INITIALIZED after initialization is finished.
  - DEFINED <devname> after a device is defined.
  - DELETED <devname> after a device was deleted.
  - RENAMED <old> <new> after a device was renamed.
  - UNDEFINED <defspec> upon reception of a message for an undefined device.
- Notify can be used to store macros for manual execution. Use the trigger command to execute the macro. E.g.
  `fhem> define MyMacro notify MyMacro { Log 1, "Hello"}`
  `fhem> trigger MyMacro`

Set

N/A

Attributes

- disable
- loglevel
- forwardReturnValue
  Forward the return value of the executed command to the caller, default is disabled (0). If enabled (1), then e.g. a set command which triggers this notify will also return this value. This can cause e.g FHEMWEB to display this value, when clicking "on" or "off", which is often not intended.

### sequence

Define

`define <name> sequence <re1> <timeout1> <re2> [<timeout2> <re3> ...]`
A sequence is used to allow to trigger events for a certain combination of button presses on a remote. E.g. to switch on a lamp when pressing the Btn1:on, then Btn2:off and at last Btn1:on one after the other you could define the following:

`define lampseq sequence Btn1:on 0.5 Btn2:off 0.5 Btn1 on
define lampon notify lampseq:trigger set lamp on`

### structure

Define

`define <name> structure <struct_type> <dev1> <dev2> ...`
The structure device is used to organize/structure a devices in order to set groups of them at once (e.g. switching everything off in a house).
The list of attached devices can be modified through the addstruct / delstruct commands. Each attached device will get the attribute <struct_type>=<name>
when it is added to the list, and the attribute will be deleted if the device is deleted from the structure. The structure devices can also be added to a structure, e.g. you can have a building consisting of levels which consists of rooms of devices.
Example:

- define kitchen structure room lamp1 lamp2
- addstruct kitchen TYPE=FS20
- delstruct kitchen lamp1
- define house structure building kitchen living
- set house off

Set

Every set command is propagated to the attached devices. Exception: if an attached devices has an attribute structexcluse, and the attribute value matches (as a regexp) the name of the current structure.

Get

get is not supported through a structure device.

Attributes

- structexclude
  exclude the device from set operations, see the set command above.

### watchdog

Define

`define <name> watchdog <regexp1> <timespec> <regexp2> <command>`
Start an arbitrary fhem.pl command if after <timespec> receiving an event matching <regexp1> no event matching <regexp2> is received.
The syntax for <regexp1> and <regexp2> is the same as the regexp for notify.
<timespec> is HH:MM[:SS]
<command> is a usual fhem command like used int the at or notify
Examples:

        # Talk to the FHT80 if we do not receive any message for 15 Minutes
        define w watchdog FHT80 00:15:00 SAME set FHT80 time

        # Shout if the HMS100-FIT is not alive
        define w watchdog HMS100-FIT 01:00:00 SAME "alarm-fit.sh"

        # Send mail if the window is left open
        define w watchdog contact1:open 00:15 contact1:closed "mail_me close window1"
        attr w regexp1WontReactivate

Notes:

- if <regexp1> is . (dot), then activate the watchdog at definition time. Else it will be activated when the first matching event is received.
- <regexp1> reactivates a running watchdog, to avoid it use the regexp1WontReactivate attribute.
- if <regexp2> is SAME, then it will be the same as the first regexp, and it will be reactivated, when it is received. This is probably the normal operation.
- trigger <watchdogname> . will activate the trigger if its state is defined, and set it into state defined if its state is triggered

- a generic watchdog (one watchdog responsible for more devices) is currently not possible.

Set

Get

N/A

Attributes

- disable
- regexp1WontReactivate
  When a watchdog is active, a second event matching regexp1 will normally reset the timeout. Set this attribute to prevents this.

### DbLog

Define

`define <name> DbLog <configfilename> <regexp>`
Log events to a database. The database connection is defined in `<configfilename>` (see sample configuration file `db.conf`). The configuration is stored in a separate file to avoid storing the password in the main configuration file and to have it visible in the output of the list command.
You must have `93_DbLog.pm` in the `FHEM` subdirectory to make this work. Additionally, the modules `DBI` and `DBD::<dbtype>` need to be installed (use `cpan -i <module>` if your distribution does not have it).
`<regexp>` is the same as in FileLog.
Sample code to create a MySQL database is in `fhemdb_create.sql`. The database contains two tables: `current` and `history`. The latter contains all events whereas the former only contains the last event for any given reading and device. The columns have the following meaning:

1. TIMESTAMP: timestamp of event, e.g. `2007-12-30 21:45:22`
2. DEVICE: device name, e.g. `Wetterstation`
3. TYPE: device type, e.g. `KS300`
4. EVENT: event specification as full string, e.g. `humidity: 71 (%)`
5. READING: name of reading extracted from event, e.g. `humidity`
6. VALUE: actual reading extracted from event, e.g. `71`
7. UNIT: unit extracted from event, e.g. `%`

The content of VALUE is optimized for automated post-processing, e.g. `yes` is translated to `1`.
The current values can be retrieved by means of the perl script `fhemdb_get.pl`. Its output is adapted to what a Cacti data input method expects. Call `fhemdb_get.pl` without parameters to see the usage information.
Examples:

`# log everything to database`
`define logdb DbLog /etc/fhem/db.conf .*:.*`

### FileLog

Define

`define <name> FileLog <filename> <regexp>`
Log events to `<filename>`. The log format is

          YYYY:MM:DD_HH:MM:SS <device> <event>

The regexp will be checked against the (complete!) device name or against the (complete!) devicename:event combination.
`<filename>` may contain one or more of the following wildcards (a subset of the Unix date command arguments):

- `%d` day of month (01..31)
- `%m` month (01..12)
- `%Y` year (1970...)
- `%w` day of week (0..6); 0 represents Sunday
- `%j` day of year (001..366)
- `%U` week number of year with Sunday as first day of week (00..53)
- `%V` week number of year with Monday as first day of week (01..53)

Examples:

`define lamplog FileLog /var/tmp/lamp.log lamp`
`define wzlog FileLog /var/tmp/wz-%Y-%U.log wz:(measured-temp|actuator).*`

Set

`set <name> reopen`
Used to reopen a FileLog after making some manual changes to the logfile.

Get

`get <name> <infile> <outfile> <from> <to> <column_spec>`
Read data from the logfile, used by frontends to plot data without direct access to the file.

- <infile>
  Name of the logfile to grep. "-" is the current logfile, or you can specify an older file (or a file from the archive).
- <outfile>
  If it is "-", you get the data back on the current connection, else it is the prefix for the output file. If more than one file is specified, the data is separated by a comment line for "-", else it is written in separate files, numerated from 0.
- <from> <to>
  Used to grep the data. The elements should correspond to the timeformat or be an initial substring of it.
- <column_spec>
  For each column_spec return a set of data in a separate file or separated by a comment line on the current connection.
  Syntax: <col>:<regexp>:<default>:<fn>
  - <col> The column number to return, starting at 1 with the date. If the column is enclosed in double quotes, then it is a fix text, not a column nuber.
  - <regexp> If present, return only lines containing the regexp. Case sensitive.
  - <default>
    If no values were found and the default value is set, then return one line containing the from value and this default. We need this feature as gnuplot aborts if a dataset has no value at all.
  - <fn> One of the following:
    - int
      Extract the integer at the beginning og the string. Used e.g. for constructs like 10%
    - delta-h or delta-d
      Return the delta of the values for a given hour or a given day. Used if the column contains a counter, as is the case for the KS300 rain column.
    - everything else
      The string is evaluated as a perl expression. @fld is the current line splitted by spaces. Note: The string/perl expression cannot contain spaces, as the part after the space will be considered as the next column_spec.

Example:

    get outlog out-2008.log - 2008-01-01 2008-01-08 4:IR:int: 9:IR::

Attributes

- archivecmd / archivedir / nrarchive
  When a new FileLog file is opened, the FileLog archiver wil be called. This happens only, if the name of the logfile has changed (due to time-specific wildcards, see the FileLog section), and there is a new entry to be written into the file.
  If the attribute archivecmd is specified, then it will be started as a shell command (no enclosing " is needed), and each % in the command will be replaced with the name of the old logfile.
  If this attribute is not set, but nrarchive and/or archivecmd is set, then all superfluous logfiles will be moved to archivedir (or deleted if archivedir is not set).
- disable
- logtype
  Used by the pgm2 webfrontend to offer gnuplot/SVG images made from the logs. The string is made up of tokens separated by comma (,), each token specifies a different gnuplot program. The token may contain a colon (:), the part before the colon defines the name of the program, the part after is the string displayed in the web frontend. Currently following types of gnuplot programs are implemented:
  - fs20
    Plots on as 1 and off as 0. The corresponding filelog definition for the device fs20dev is:
    define FileLog fslog fs20dev /var/log/fs20dev-%Y-%U.log
  - fht
    Plots the measured-temp/desired-temp/actuator lines. The corresponding filelog definitions (for the FHT device named fht1) looks like:
    `define fhtlog1 FileLog fht1:.*(temp|actuator).* /var/log/fht1-%Y-%U.log`
  - temp4rain10
    Plots the temperature and rain (per hour and per day) of a ks300. The corresponding filelog definitions (for the KS300 device named ks300) looks like:
    define FileLog ks300log ks300:.*H:.* /var/log/ks300-%Y-%U.log
  - hum6wind8
    Plots the humidity and wind values of a ks300. The corresponding filelog definition is the same as above, both programs evaluate the same log.
  - text
    Shows the logfile as it is (plain text). Not gnuplot definition is needed.
  Example:
  attr ks300log1 logtype temp4rain10:Temp/Rain,hum6wind8:Hum/Wind,text:Raw-data

### dummy

### SUNRISE_EL

This module is used to define the functions

    sunrise, sunset,
    sunrise_rel, sunset_rel
    sunrise_abs, sunset_abs
    isday

perl functions, to be used in at or FS20 on-till commands.
First you should set the longitude and latitude global attributes to the exact longitude and latitude values (see e.g. maps.google.com for the exact values, which should be in the form of a floating point value). The default value is Frankfurt am Main, Germany.
The default altitude ($altit in SUNRISE_EL.pm) defines the sunrise/sunset for Civil twilight (i.e. one can no longer read outside without artificial illumination), which differs from sunrise/sunset times found on different websites. See perldoc "DateTime::Event::Sunrise" for alternatives.
sunrise()/sunset() returns the absolute time of the next sunrise/sunset, adding 24 hours if the next event is tomorrow, to use it in the timespec of an at device or for the on-till command for FS20 devices.
sunrise_rel()/sunset_rel() returns the relative time to the next sunrise/sunset.
sunrise_abs()/sunset_abs() return the absolute time of the corresponding event today (no 24 hours added).
All functions take up to three arguments:

- The first specifies an offset (in seconds), which will be added to the event.
- The second and third specify min and max values (format: "HH:MM").

isday() can be used in some notify or at commands to check if the sun is up or down.

Attributes

- latitude
  If set, this latitude is used to calculate sunset/sunrise
  Notation need to be in decimal format (for example Berlin = 52.666) As default Frankfurt/Main, Germany (50.112) is used.
- longitude
  If set, this longitude is used to calculate sunset/sunrise
  Notation need to be in decimal format (for example Berlin = 13.400) As default Frankfurt/Main, Germany (8.686) is used.
Note: these are global attributes, e.g.

attr global latitude 50.112
attr global longitude 8.686

### FHEMRENDERER

The FHEMRENDERER module is intended to render (draw) graphics based on the FHEM Log-Files. This can be done either based on a timer (used in the module) or based on a direct call of GET. The rendered graphics will be stored in a pre-defined directory with a predefined prefix of the files. The renderer can also work in a multi-process mode, which doesn't block the main FHEM-Loop.
Define

`define <name> FHEMRENDERER [global]`
This defines a new "device", that is of type FHEMRENDERER. The option 'global' can be used if needed for sorting reasons. Otherwise this option has no real meaning for FHEMRENDERER.
As a side-effect of defining this "device" the following attributes will be set for this "device":
plotmode gnuplot
plotsize 800,200
refresh 00:10:00
room Unsorted
status off
tmpfile /tmp/
multiprocess off
NOTE: The Logfile will report (with LogLevel 2) that the FHEMRENDERER has been defined.

Set

`set <name> <value>`
Set either on or off.
This switches the timer-based rendering on/off. The attribute 'status' will be modified accordingly.
NOTE: only WebLink based graphics will be rendered.

Get

`get <name> <[[file-name] device type logfile [pos=zoom=XX&off=YY]]>`
The get function supports different sets of arguments:
Arguments:
NONE: all WebLink based FilePlots will be rerendered
The resulting filename will be '.png'
THREE: device type logfile
In this case only one specific graphic will be rendered:
A graphic will be rendered for 'device', where device is a FileLog, based on the type 'type' based on the given 'logfile'
The resulting filename will be 'attr-tmpfile logfile.png'
FOUR: file-name device type logfile
In this case only one specific graphic will be rendered:
A graphic will be rendered for 'device', where device is a FileLog, based on the type 'type' based on the given 'logfile'
The resulting filename will be 'attr-tmpfile file-name.png'
FIVE: file-name device type logfile pos=zoom=XX&off=YYY
In this case only one specific graphic will be rendered assuming that plotmode is 'gnuplot-scroll':
A graphic will be rendered for 'device', where device is a FileLog, based on the type 'type' based on the given 'logfile'
The 'zoom' will be either qday/day/week/month/year (same as used in FHEMWEB).
The offset 'off' is either 0 (then the second part can be omitted), or -1/-2.... to jump back in time.
The resulting filename will be 'attr-tmpfile file-name.png'
NOTE: If you want to use zoom AND offset then you have to concatenate via '&' !!
NOTE: combinations are possible in limited ranges:
meaning: you can add the 'pos=zoom=XX&off=YY' to any of the first three sets.
This may e.g. result in rendering all WebLinks with a specific zoom or offset
(if you just pass the 'pos=zoom=xx&off=yy' parameter);
Any rendered image (one or all WebLinks) will be stored in 'attr-tmpfile' followed by a 'filename.png'. The filename will be either derived (from weblink-name or logfile-name) or, for single files, can be assigend.

Attributes

- plotmode
  Specifies how to generate the plots:
  - gnuplot
    Call the gnuplot script with each logfile. The filename specification of the FileLog device will determine what is in the plot. The data is converted into an image on the backend with gnuplot.
  - gnuplot-scroll
    FHEMRENDERER will offer zoom and offset possibilities in order to navigate in the current logfile, i.e. you can select just a part of the data to be displayed. The more data is contained in a single logfile, the easier you can navigate. The recommendation is to store the data for a whole year in one logfile. The data is converted into an image on the backend with gnuplot.
- plotsize
  the default size of the plot, in pixels, separated by comma: width,height. You can set individual sizes by setting the plotsize of the weblink.
- status
  Reflects the status, if the renderer timer has been set to ON or OFF. By reading the status, you can detect, if the timer is running, or not.
- refresh
  This defines the time-interval in which a new rendering of the defined WebLinks will be done.
- tmpfile
  This gives the path and a possible prefix for the rendered filenames.
  You can specify a path to which the files will be rendered. If you also specify a prefix, this will be used to build the resulting filename.
- multiprocess
  This defines if the Renderer works in a multiprocessing mode.
  You can set multiprocessing either to on / off and the renderer will draw the time-scheduled tasks either in multiprocessing mode, or not. NOTE: Direct GET calls, except for a general GET (for all weblinks) will be renderer in an interactive mode, meaning that the FHEM-Loop will be block as long as the graphics are rendered. If you want to use multiprocessing, set the RENDERER and multiprocessing to on and the weblink-graphics will be rendered in the background.

### Perl specials

If you want to automate some tasks via fhem, then you'll probably use at or notify. For more complex tasks you'll use either a shell-script or a perl "oneliner" as the at/notify argument. This chapter gives some tips in using the perl oneliners.
- To test perl oneliners, type them on the telnet prompt (or FHEMWEB text input) by enclosing it in {}, one line at once. The last line will only write something in the logfile, the output of the other lines is directly visible.
  { "Hello" }
  { 1+3*4 }
  { `ls /etc` }
  { Log 1, "Hello" }
- Perl expressions are separated by ;, in fhem oneliners they have to escaped with ;;
  { my $a = 1+1;; Log 1, "Hello $a" }
- To use fhem commands from the perl expression, use the function fhem(), which takes a string argument, this string will be evaluated as a fhem command:
  { fhem "set light on" }
  define n1 notify piri:on { fhem "set light on" }
- Notify can be used to store macros for manual execution. Use the trigger command to execute the macro:
  define MyMacro notify MyMacro { Log 1, "Hello"}
  trigger MyMacro
  define MacroWithArg notify MyMacro { Log 1, "Hello %"}
  trigger MyMacro MyArg
- To make date and time handling easier, the variables $sec, $min, $hour, $mday, $month, $year, $wday, $yday, $isdst are available in the perl oneliners (see also perldoc -f localtime). Exceptions: $month is in the range of 1 to 12, and $year is corrected by 1900 (as I would expect).
  Additionally the variabe $we is 1 if it is weekend (i.e $wday == 0 or $wday == 6), and 0 otherwise. If the holida2we global attribute is set, $we is 1 for holidays too.
  define n2 notify piri:on { if($hour > 18 || $hour < 5) { fhem "set light on" } }
  define roll_en *07:45:00 { fhem "trigger SwitchAllRoll on" if(!$we) }
  define roll_en *08:30:00 { fhem "trigger SwitchAllRoll on" if($we) }
- The following helper functions are defined in 99_Util.pm (which will be loaded automatically, as every module with prefix 99):
  - min(a,b), max(a,b)
  - time_str2num("YYYY-MM-DD HH:MM:SS") returns a numerical value, which makes computation of time differences easier
  - abstime2rel("HH:MM:SS") converts an absolute time to a relative one
- To access the device states/attributes, use the following functions:
  - Value(<devicename>)
    returns the state of the device (the string you see in paranthesis in the output of the list command).
  - OldValue(<devicename>)
  - OldTimestamp(<devicename>)
    returns the old value/timestamp of the device.
  - ReadingsVal(<devicename>,<reading>,<defaultvalue>)
    Return the reading (the value in the Readings section of "list device")
  - AttrVal(<devicename>,<attribute>,<defaultvalue>)
    Return the attribute of the device
    { Value("wz") }
    { OldValue("wz") }
    { time_str2num(OldTimestamp("wz")) }
    { ReadingsVal("wz", "measured-temp", "20")+0 }
    { AttrVal("wz", "room", "none") }
- By using the 99_SUNRISE_EL.pm module, you have access to the following functions:
  sunset($offset, $min, $max)
  sunrise($offset, $min, $max)
  isday()
  offset is in seconds, and the format of min/max is "HH:MM" or "HH:MM:SS". isday returns 1 if the sun is visible, and 0 else.
