# FHEM module to commmunicate with 1-Wire adressable switches DS2413, DS206, DS2408
#
# Attention: This module may communicate with the OWX module,
# but currently not with the 1-Wire File System OWFS
#
# TODO: Kanalattribute ändern zur Laufzeit.
#
#
# Prefixes for subroutines of this module:
# OW = General 1-Wire routines Peter Henning)
# OWX = 1-Wire bus master interface (Peter Henning)
# OWFS = 1-Wire file system (??)
#
# Prof. Dr. Peter A. Henning, 2012
#
# Version 2.24 - October, 2012
#
# Setup bus device in fhem.cfg as
#
# define <name> OWSWITCH [<model>] <ROM_ID> [interval]
#
# where <name> may be replaced by any name string
#
# <model> is a 1-Wire device type. If omitted, we assume this to be an
# DS2413. Allowed values are DS2413, DS2406
# <ROM_ID> is a 12 character (6 byte) 1-Wire ROM ID
# without Family ID, e.g. A2D90D000800
# [interval] is an optional query interval in seconds
#
# get <name> id => FAM_ID.ROM_ID.CRC
# get <name> present => 1 if device present, 0 if not
# get <name> interval => query interval
# get <name> input <channel-name> => state for channel (name A, B or defined channel name)
# note: this value reflects the measured value, not necessarily the one set as
# output state, because the output transistors are open collector switches. A measured
# state of 1 = OFF therefore corresponds to an output state of 1 = OFF, but a measured
# state of 0 = ON can also be due to an external shortening of the output.
# get <name> gpio => values for channels
#
# set <name> interval => set period for measurement
# set <name> output <channel-name> ON|OFF => set value for channel (name A, B or defined channel name)
# note: 1 = OFF, 0 = ON in normal usage. See also the note above
# set <name> gpio value => set values for channels (3 = both OFF, 1 = B ON 2 = A ON 0 = both ON)
# set <name> init yes => re-initialize device
#
# Additional attributes are defined in fhem.cfg, in some cases per channel, where <channel>=A,B
# Note: attributes are read only during initialization procedure - later changes are not used.
#
# attr <name> event on-change/on-update = when to write an event (default= on-update)
#
# attr <name> <channel>Name <string>|<string> = name for the channel | a type description for the measured value
# attr <name> <channel>Unit <string>|<string> = values to display in state variable for on|off condition
# attr <name> <channel>stateS <string> = character string denoting external shortening condition

#
# FHEM module to commmunicate with 1-Wire temperature sensors DS1820, DS18S20, DS18B20, DS1822
#
# Attention: This module may communicate with the OWX module,
# and also with the 1-Wire File System OWFS
#
# Prefixes for subroutines of this module:
# OW = General 1-Wire routines (Martin Fischer, Peter Henning)
# OWFS = 1-Wire file system (Martin Fischer)
# OWX = 1-Wire bus master interface (Peter Henning)
#
# Prof. Dr. Peter A. Henning, 2012
# Martin Fischer, 2011
#
# Version 2.24 - October, 2012
#
# Setup bus device in fhem.cfg as
#
# define <name> OWTHERM [<model>] <ROM_ID> [interval]
#
# where <name> may be replaced by any name string
#
# <model> is a 1-Wire device type. If omitted, we assume this to be an
# DS1820 temperature sensor
# Currently allowed values are DS1820, DS18B20, DS1822
# <ROM_ID> is a 12 character (6 byte) 1-Wire ROM ID
# without Family ID, e.g. A2D90D000800
# [interval] is an optional query interval in seconds
#
# get <name> id => OW_FAMILY.ROM_ID.CRC
# get <name> present => 1 if device present, 0 if not
# get <name> interval => query interval
# get <name> temperature => temperature measurement
# get <name> alarm => alarm temperature settings
#
# set <name> interval => set period for measurement
# set <name> tempLow => lower alarm temperature setting
# set <name> tempHigh => higher alarm temperature setting
#
# Additional attributes are defined in fhem.cfg
# Note: attributes "tempXXXX" are read during every update operation.
#
# attr <name> event on-change/on-update = when to write an event (default= on-update)
#
# attr <name> stateAL "<string>" = character string for denoting low alarm condition, default is red down triangle
# attr <name> stateAH "<string>" = character string for denoting high alarm condition, default is red up triangle
# attr <name> tempOffset <float> = temperature offset in degree Celsius added to the raw temperature reading
# attr <name> tempUnit <string> = unit of measurement, e.g. Celsius/Kelvin/Fahrenheit or C/K/F, default is Celsius
# attr <name> tempLow <float> = value for low alarm
# attr <name> tempHigh <float> = value for high alarm
