PRESENCE

    The PRESENCE module provides several possibilities to check the presence of mobile phones or similar mobile devices such as tablets.

    This module provides several operational modes to serve your needs. These are:

    • lan-ping - A presence check of a device via network ping in your LAN/WLAN.
    • fritzbox - A presence check by requesting the device state from the FritzBox internals (only available when running FHEM on a FritzBox!).
    • local-bluetooth - A presence check by searching directly for a given bluetooth device nearby.
    • function - A presence check by using your own perl function which returns a presence state.
    • shellscript - A presence check by using an self-written script or binary which returns a presence state.
    • event - A presence check by listening to FHEM events of other definitions.
    • lan-bluetooth - A presence check of a bluetooth device via LAN network by connecting to a presenced or collectord instance.

    Each mode can be optionally configured with a specific check interval and a present check interval.

    • check-interval - The interval in seconds between each presence check. Default value: 30 seconds
    • present-check-interval - The interval in seconds between each presence check in case the device is present. Otherwise the normal check-interval will be used.


    Define

      Mode: lan-ping

      define <name> PRESENCE lan-ping <ip-address> [ <check-interval> [ <present-check-interval> ] ]

      Checks for a network device via PING requests and reports its presence state.

      Example

      define iPhone PRESENCE lan-ping 192.168.179.21

      Mode: fritzbox

      define <name> PRESENCE fritzbox <device-name/mac-address> [ <check-interval> [ <present-check-interval> ] ]

      Checks for a network device by requesting the internal state on a FritzBox via ctlmgr_ctl. The device-name must be the same as shown in the network overview of the FritzBox or can be substituted by the MAC address with the format XX:XX:XX:XX:XX:XX

      This check is only applicable when FHEM is running on a FritzBox! The detection of absence can take about 10-15 minutes!

      Example

      define iPhone PRESENCE fritzbox iPhone-6
      define iPhone PRESENCE fritzbox 00:06:08:05:0D:00

      Mode: local-bluetooth

      define <name> PRESENCE local-bluetooth <bluetooth-address> [ <check-interval> [ <present-check-interval> ] ]

      Checks for a bluetooth device and reports its presence state. For this mode the shell command "hcitool" is required (provided with a bluez installation under Debian via APT), as well as a functional bluetooth device directly attached to your machine.

      Example

      define iPhone PRESENCE local-bluetooth 0a:8d:4f:51:3c:8f

      Mode: function

      define <name> PRESENCE function {...} [ <check-interval> [ <present-check-interval> ] ]

      Checks for a presence state via perl-code. You can use a self-written perl function to obtain the presence state of a specific device (e.g. via SNMP check).

      The function must return 0 (absent) or 1 (present). An example can be found in the FHEM-Wiki.

      Example

      define iPhone PRESENCE function {snmpCheck("10.0.1.1","0x44d77429f35c")}

      Mode: shellscript

      define <name> PRESENCE shellscript "<path> [<arg1>] [<argN>]..." [ <check-interval> [ <present-check-interval> ] ]

      Checks for a presence state via shell script. You can use a self-written script or binary in any language to obtain the presence state of a specific device (e.g. via SNMP check).

      The shell must return 0 (absent) or 1 (present) on console (STDOUT). Any other values will be treated as an error

      Example

      define iPhone PRESENCE shellscript "/opt/check_device.sh iPhone"

      Mode: event

      define <name> PRESENCE event <absent-regexp> <present-regexp>

      Listens for events of other FHEM definitions to determine a presence state. You must provide two event regexp's in the same style as for the notify module.

      If an event matches one of the provides regexps, the presence state will be changed.

      Example

      define Presence_John PRESENCE event Door_Switch:off Door_Switch:on

      Mode: lan-bluetooth

      Checks for a bluetooth device with the help of presenced or collectord. They can be installed where-ever you like, just must be accessible via network. The given device will be checked for presence status.

      define <name> PRESENCE lan-bluetooth <bluetooth-address> <ip-address>[:port] [ <check-interval> ]

      The default port is 5111 (presenced). Alternatly you can use port 5222 (collectord)

      Example

      define iPhone PRESENCE lan-bluetooth 0a:4f:36:d8:f9:89 127.0.0.1:5222

      presenced

        The presence is a perl network daemon, which provides presence checks of multiple bluetooth devices over network. It listens on TCP port 5111 for incoming connections from a FHEM PRESENCE instance or a running collectord.
        Usage:
          presenced [-d] [-p <port>] [-P <filename>]
          presenced [-h | --help]
        
        
        Options:
          -p, --port
             TCP Port which should be used (Default: 5111)
          -P, --pid-file
             PID file for storing the local process id (Default: /var/run/presenced.pid)
          -d, --daemon
             detach from terminal and run as background daemon
          -n, --no-timestamps
             do not output timestamps in log messages
          -v, --verbose
             Print detailed log output
          -h, --help
             Print detailed help screen
        
        It uses the hcitool command (provided by a bluez installation) to make a paging request to the given bluetooth address (like 01:B4:5E:AD:F6:D3). The devices must not be visible, but still activated to receive bluetooth requests.

        If a device is present, this is send to FHEM, as well as the device name as reading.

        The presenced is available as:



      lepresenced

        lepresenced is a Perl network daemon that provides presence checks of multiple bluetooth devices over network. In contrast to presenced, lepresenced covers Bluetooth 4.0 (low energy) devices, i. e. Gigaset G-Tags, FitBit Charges. lepresenced listens on TCP port 5333 for connections of a PRESENCE definition or collectord.
        Usage:
            lepresenced --bluetoothdevice <bluetooth device> --listenaddress <listen address> --listenport <listen port> --loglevel <log level> --daemon
            lepresenced -b <bluetooth device> -a <listen address> -p <listen port> -l <log level> -d
        
        valid log levels:
            LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG. Default: LOG_INFO
        
        Examples:
            lepresenced --bluetoothdevice hci0 --listenaddress 127.0.0.1 --listenport 5333 --daemon
            lepresenced --loglevel LOG_DEBUG --daemon
        
        To detect the presence of a device, it uses the command hcitool lescan (package: bluez) to continuously listen to beacons of Bluetooth LE devices.

        If a device is present, this is send to FHEM, as well as the device name as reading.

        The presenced is available as:



      collectord

        The collectord is a perl network daemon, which handles connections to several presenced installations to search for multiple bluetooth devices over network.

        It listens on TCP port 5222 for incoming connections from a FHEM presence instance.
        Usage:
          collectord -c <configfile> [-d] [-p <port>] [-P <pidfile>]
          collectord [-h | --help]
        
        
        Options:
          -c, --configfile <configfile>
             The config file which contains the room and timeout definitions
          -p, --port
             TCP Port which should be used (Default: 5222)
          -P, --pid-file
             PID file for storing the local process id (Default: /var/run/collectord.pid)
          -d, --daemon
             detach from terminal and run as background daemon
          -n, --no-timestamps
             do not output timestamps in log messages
          -v, --verbose
             Print detailed log output
          -l, --logfile <logfile>
             log to the given logfile
          -h, --help
             Print detailed help screen
        
        Before the collectord can be used, it needs a config file, where all different rooms, which have a presenced detector, will be listed. This config file looks like:

            # room definition
            # ===============
            #
            [room-name]              # name of the room
            address=192.168.0.10     # ip-address or hostname
            port=5111                # tcp port which should be used (5111 is default)
            presence_timeout=120     # timeout in seconds for each check when devices are present
            absence_timeout=20       # timeout in seconds for each check when devices are absent
        
            [living room]
            address=192.168.0.11
            port=5111
            presence_timeout=180
            absence_timeout=20
        
        If a device is present in any of the configured rooms, this is send to FHEM, as well as the device name as reading and the room which has detected the device.

        The collectord is available as:




    Set
    • statusRequest - Schedules an immediatly check.
    • power - Executes the given power command which is set as attribute to power (on or off) the device (only when attribute "powerCmd" is set)
    • overrideInterval - Override the check interval to the given number of seconds. (not applicable in mode "event" and "lan-bluetooth")

    Attributes

    • do_not_notify
    • readingFnAttributes

    • disable
    • If this attribute is activated, an active check will be disabled.

      Possible values: 0 => not disabled , 1 => disabled
      Default Value is 0 (not disabled)

    • absenceThreshold

    • (not applicable in mode "event" )
      The number of checks that have to result in "absent" before the state of the PRESENCE definition is changed to "absent". This can be used to verify the absence of a device with multiple check runs before the state is finally changed to "absent". If this attribute is set to a value >1, the reading state and presence will be set to "maybe absent" during the absence verification.

      Default Value is 1 (no absence verification)

    • presenceThreshold

    • (not applicable in mode "event" )
      The number of checks that have to result in "present" before the state of the PRESENCE definition is changed to "present". This can be used to verify the permanent presence of a device with multiple check runs before the state is finally changed to "present". If this attribute is set to a value >1, the reading state and presence will be set to "maybe present" during the presence verification.

      Default Value is 1 (no presence verification)

    • absenceTimeout

    • (only in mode "event" applicable)
      The timeout after receiving an "absent" event, before the state of the PRESENCE definition is switched to "absent". This can be used to verify the permanent absence by waiting a specific time frame to not receive an "present" event. If this timeout is reached with no "present" event received in the meantime, the presence state will finally be set to "absent". The timeout is given in HH:MM:SS format, where hours and minutes are optional. If this attribute is set to a valid value, the reading state and presence will be set to "maybe absent" during the absence verification.

      Default Value is 0 (no absence verification)

    • presenceTimeout

    • (only in mode "event" applicable)
      The timeout after receiving an "present" event, before the state of the PRESENCE definition is switched to "present". This can be used to verify the permanent presence by waiting a specific time frame to not receive an "absent" event. If this timeout is reached with no "absent" event received in the meantime, the presence state will finally be set to "present". The timeout is given in HH:MM:SS format, where hours and minutes are optional. If this attribute is set to a valid value, the reading state and presence will be set to "maybe present" during the presence verification.

      Default Value is 0 (no presence verification)

    • retryInterval

    • (Not applicable in mode "event" or "lan-bluetooth")
      The check interval in case a check is prematurely aborted and was unable to check the presence. In this case, PRESENCE reschedules the next check as retry within the given retry interval in seconds (usually lower than the regular check interval).

      Default Value is 10 seconds

    • retryCount

    • (Not applicable in mode "event" or "lan-bluetooth")
      The maximum number of checks to perform within the retryInterval in case a check is prematurely aborted and was unable to check the presence. PRESENCE will try to retry after a failed check to a maximum of the given number of tries. If all retries fails also, it will uses afterwards the regular check interval.

      Default Value is 3 (number of check retries)

    • pingCount
    • (Only in mode "ping" applicable)
      Changes the count of the used ping packets to recognize a present state. Depending on your network performance sometimes a packet can be lost or blocked.

      Default Value is 4 (packets)

    • bluetoothHciDevice
    • (Only in Mode "local-bluetooth" applicable)
      Set a specific bluetooth HCI device to use for scanning. If you have multiple bluetooth modules connected, you can select a specific one to use for scanning (e.g. hci0, hci1, ...).

    • fritzboxCheckSpeed
    • (Only in Mode "fritzbox" applicable)
      When this attribute is enabled, the network speed is checked in addition to the device state.
      This only makes sense for wireless devices connected directly to the FritzBox.

      Possible values: 0 => do not check speed, 1 => check speed when device is active
      Default value is 0 (no speed check)

    • powerCmd

    • Define a FHEM command, which powers on or off the device.

      When executing the powerCmd (set command: power) following placeholders will be replaced by there corresponding values:

PRESENCE

    Das PRESENCE Module bietet mehrere Möglichkteiten um die Anwesenheit von Handys/Smartphones oder anderen mobilen Geräten (z.B. Tablets) zu erkennen.

    Dieses Modul bietet dazu mehrere Modis an um Anwesenheit zu erkennen. Diese sind:

    • lan-ping - Eine Erkennung auf Basis von Ping-Tests im lokalen LAN/WLAN
    • fritzbox - Eine Erkennung aufgrund der internen Abfrage des Status auf der FritzBox (nur möglich, wenn FHEM auf einer FritzBox läuft)
    • local-bluetooth - Eine Erkennung auf Basis von Bluetooth-Abfragen durch den FHEM Server. Das Gerät muss dabei in Empfangsreichweite sein, aber nicht sichtbar sein
    • function - Eine Erkennung mithilfe einer selbst geschriebenen Perl-Funktion, welche den Anwesenheitsstatus ermittelt.
    • shellscript - Eine Erkennung mithilfe eines selbst geschriebenen Skriptes oder Programm (egal in welcher Sprache).
    • event - Eine Erkennung basierend auf Events einer anderen Definition in FHEM.
    • lan-bluetooth - Eine Erkennung durch Bluetooth-Abfragen via Netzwerk (LAN/WLAN) in ein oder mehreren Räumen

    Jeder Modus kann optional mit spezifischen Prüf-Intervallen ausgeführt werden.

    • check-interval - Das normale Prüfinterval in Sekunden für eine Anwesenheitsprüfung. Standardwert: 30 Sekunden
    • present-check-interval - Das Prüfinterval in Sekunden, wenn ein Gerät anwesend (present) ist. Falls nicht angegeben, wird der Wert aus check-interval verwendet


    Define

      Modus: lan-ping

      define <name> PRESENCE lan-ping <IP-Addresse oder Hostname> [ <Interval> [ <Anwesend-Interval> ] ]

      Prüft ob ein Gerät über Netzwerk (üblicherweise WLAN) auf Ping-Anfragen reagiert und setzt entsprechend den Anwesenheitsstatus.

      Beispiel

      define iPhone PRESENCE lan-ping 192.168.179.21

      Modus: fritzbox

      define <name> PRESENCE fritzbox <Gerätename/MAC-Adresse> [ <Interval> [ <Anwesend-Interval> ] ]

      Prüft ob ein Gerät welches per WLAN mit der FritzBox verbunden ist, erreichbar durch Abfrage des Status mit dem Befehl ctlmgr_ctl. Der Gerätename (Parameter: <Gerätename>) muss dem Namen entsprechen, welcher im Menüpunkt "Heimnetz" auf der FritzBox-Oberfläche angezeigt wird oder kann durch die MAC-Adresse im Format XX:XX:XX:XX:XX:XX ersetzt werden.

      Dieser Modus ist nur verwendbar, wenn FHEM auf einer FritzBox läuft! Die Erkennung einer Abwesenheit kann ca. 10-15 Minuten dauern!

      Beispiel

      define iPhone PRESENCE fritzbox iPhone-6
      define iPhone PRESENCE fritzbox 00:06:08:05:0D:00

      Modus: local-bluetooth

      define <name> PRESENCE local-bluetooth <Bluetooth-Adresse> [ <Interval> [ <Anwesend-Interval> ] ]

      Prüft ob ein Bluetooth-Gerät abgefragt werden kann und meldet dies als Anwesenheit. Für diesen Modus wird der Shell-Befehl "hcitool" benötigt (wird durch das Paket bluez bereitgestellt), sowie ein funktionierender Bluetooth-Empfänger (intern oder als USB-Stick)

      Beispiel

      define iPhone PRESENCE local-bluetooth 0a:4f:36:d8:f9:8

      Modus: function

      define <name> PRESENCE function {...} [ <Interval> [ <Anwesend-Interval> ] ]

      Prüft den Anwesenheitsstatus mithilfe einer selbst geschriebenen Perl-Funktion (z.B. SNMP Abfrage).

      Diese Funktion muss 0 (Abwesend) oder 1 (Anwesend) zurückgeben. Ein entsprechendes Beispiel findet man im FHEM-Wiki.

      Beispiel

      define iPhone PRESENCE function {snmpCheck("10.0.1.1","0x44d77429f35c")

      Mode: shellscript

      define <name> PRESENCE shellscript "<Skript-Pfad> [<arg1>] [<argN>]..." [ <Interval> [ <Anwesend-Interval> ] ]

      Prüft den Anwesenheitsstatus mithilfe eines selbst geschrieben Skripts oder Programmes (egal in welcher Programmier-/Skriptsprache)

      Der Aufruf dieses Skriptes muss eine 0 (Abwesend) oder 1 (Anwesend) auf der Kommandozeile (STDOUT) ausgeben. Alle anderen Werte/Ausgaben werden als Fehler behandelt.

      Beispiel

      define iPhone PRESENCE shellscript "/opt/check_device.sh iPhone"

      Mode: event

      define <name> PRESENCE event <Abwesend-Regexp> <Anwesend-Regexp>

      Lauscht auf Events von anderen Definitionen innerhalb von FHEM um die Anwesenheit darzustellen. Die regulären Ausdrücke für An- und Abwesenheit entsprechen dabei der Syntax von notify.

      Sobald innerhalb von FHEM ein Event gefeuert wird, welches auf die Abwesend-Regexp bzw. Anwesend-Regexp passt, wird der Status entsprechend in PRESENCE gesetzt.

      Beispiel

      define Anwesenheit PRESENCE event Tuerschalter:off Tuerschalter:on

      Modus: lan-bluetooth

      Prüft ein Bluetooth-Gerät auf Anwesenheit über Netzwerk mit Hilfe von presenced oder collectord. Diese können auf jeder Maschine installiert werden, welche eine Standard-Perl-Umgebung bereitstellt und über Netzwerk erreichbar ist.

      define <name> PRESENCE lan-bluetooth <Bluetooth-Adresse> <IP-Adresse>[:Port] [ <Interval> ]

      Der Standardport ist 5111 (presenced). Alternativ kann man den Port 5222 (collectord) nutzen. Generell ist der Port aber frei wählbar.

      Beispiel

      define iPhone PRESENCE lan-bluetooth 0a:4f:36:d8:f9:89 127.0.0.1:5222

      presenced

        Der presenced ist ein Perl Netzwerkdienst, welcher eine Bluetooth-Anwesenheitserkennung von ein oder mehreren Geräten über Netzwerk bereitstellt. Dieser lauscht standardmäßig auf TCP Port 5111 nach eingehenden Verbindungen von dem PRESENCE Modul oder einem collectord.
        Usage:
          presenced -d [-p <port>] [-P <filename>]
          presenced [-h | --help]
        
        
        Options:
          -p, --port
             TCP Port which should be used (Default: 5111)
          -P, --pid-file
             PID file for storing the local process id (Default: /var/run/presenced.pid)
          -d, --daemon
             detach from terminal and run as background daemon
          -v, --verbose
             Print detailed log output
          -h, --help
             Print detailed help screen
        
        Zur Bluetooth-Abfrage wird der Shell-Befehl "hcitool" verwendet (Paket: bluez) um sogenannte "Paging-Request" an die gewünschte Bluetooth Adresse (z.B. 01:B4:5E:AD:F6:D3) durchzuführen. Das Gerät muss dabei nicht sichtbar sein, allerdings ständig aktiviert sein um Bluetooth-Anfragen zu beantworten.

        Wenn ein Gerät anwesend ist, wird dies an FHEM übermittelt zusammen mit dem Gerätenamen als Reading.

        Der presenced ist zum Download verfügbar als:



      lepresenced

        lepresenced ist ein Perl Netzwerkdienst, der analog zu presenced eine Bluetooth-Anwesenheitserkennung von ein oder mehreren Geräten über Netzwerk bereitstellt. Im Gegensatz zu presenced unterstützt lepresenced Bluetooth 4.0 (Low Energy) Geräte wie z. B. Gigaset G-Tags, FitBit Charges. lepresenced lauscht standardmäßig auf TCP Port 5333 und wartet auf eingehende Verbindungen des PRESENCE-Moduls bzw. von collectord.
        Usage:
            lepresenced --bluetoothdevice <bluetooth device> --listenaddress <listen address> --listenport <listen port> --loglevel <log level> --daemon
            lepresenced -b <bluetooth device> -a <listen address> -p <listen port> -l <log level> -d
        
        valid log levels:
            LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG. Default: LOG_INFO
        
        Examples:
            lepresenced --bluetoothdevice hci0 --listenaddress 127.0.0.1 --listenport 5333 --daemon
            lepresenced --loglevel LOG_DEBUG --daemon
        
        Zur Bluetooth-Abfrage wird der Befehl hcitool lescan (Paket: bluez) verwendet, der fortwährend auf die Beacons der Bluetooth-LE-Geräte lauscht.

        Wenn ein Gerät anwesend ist, wird dies an FHEM übermittelt zusammen mit dem Gerätenamen als Reading.

        Der le presenced ist zum Download verfügbar als:



      collectord

        Der collectord ist ein Perl Netzwerk Dienst, welcher Verbindungen zu mehreren presenced-Instanzen verwaltet um eine koordinierte Suche nach ein oder mehreren Bluetooth-Geräten über Netzwerk durchzuführen.

        Er lauscht auf TCP port 5222 nach eingehenden Verbindungen von einem PRESENCE Modul.
        Usage:
          collectord -c <configfile> [-d] [-p <port>] [-P <pidfile>]
          collectord [-h | --help]
        
        
        Options:
          -c, --configfile <configfile>
             The config file which contains the room and timeout definitions
          -p, --port
             TCP Port which should be used (Default: 5222)
          -P, --pid-file
             PID file for storing the local process id (Default: /var/run/collectord.pid)
          -d, --daemon
             detach from terminal and run as background daemon
          -v, --verbose
             Print detailed log output
          -l, --logfile <logfile>
             log to the given logfile
          -h, --help
             Print detailed help screen
        
        Bevor der collectord verwendet werden kann, benötigt er eine Konfigurationsdatei in welcher alle Räume mit einem presenced-Agenten eingetragen sind. Diese Datei sieht wie folgt aus:

            # Raum Definitionen
            # =================
            #
            [Raum-Name]              # Name des Raumes
            address=192.168.0.10     # IP-Adresse oder Hostname
            port=5111                # TCP Port welcher benutzt werden soll (standardmäßig 5111)
            presence_timeout=120     # Prüfinterval in Sekunden für jede Abfrage eines Gerätes, welches anwesend ist
            absence_timeout=20       # Prüfinterval in Sekunden für jede Abfrage eines Gerätes, welches abwesend ist
        
            [Wohnzimmer]
            address=192.168.0.11
            port=5111
            presence_timeout=180
            absence_timeout=20
        

        Wenn ein Gerät in irgend einem Raum anwesend ist, wird dies an FHEM übermittelt, zusammen mit dem Gerätenamen und dem Raum, in welchem das Gerät erkannt wurde.

        Der collectord ist zum Download verfügbar als:
