Somfy Tahoma Binding

This binding integrates the Somfy Tahoma and Somfy Connexoon home automation systems.

Supported Things

Currently these things are supported:

  • bridge (Somfy Tahoma bridge, which can discover gateways, roller shutters, awnings, switches and action groups)
  • gateways (Somfy Tahoma gateway - gateway status)
  • roller shutters (UP, DOWN, STOP control of a roller shutter). IO Homecontrol devices are allowed to set exact position of a shutter (0-100%)
  • blinds (UP, DOWN, STOP control of a blind). IO Homecontrol devices are allowed to set exact position of a blinds (0-100%) as well as orientation of slats (0-100%)
  • screens (UP, DOWN, STOP control of a screen). IO Homecontrol devices are allowed to set exact position of a screen (0-100%)
  • garage doors (UP, DOWN, STOP control of a garage door). IO Homecontrol devices are allowed to set exact position of a garage door (0-100%)
  • awnings (UP, DOWN, STOP control of an awning). IO Homecontrol devices are allowed to set exact position of an awning (0-100%)
  • windows (UP, DOWN, STOP control of a window). IO Homecontrol devices are allowed to set exact position of a window (0-100%)
  • pergolas (UP, DOWN, STOP control of a pergola). IO Homecontrol devices are allowed to set exact position of a pergola (0-100%)
  • on/off switches (connected by RTS, IO protocol or supported by USB stick - z-wave, enocean, ..)
  • light switches (similar to on/off)
  • light sensors (luminance value)
  • occupancy sensors (OPEN/CLOSE contact)
  • smoke sensors (OPEN/CLOSE contact)
  • contact sensors (OPEN/CLOSE contact)
  • temperature sensor (get temperature)
  • door locks (LOCK/UNLOCK, OPEN/CLOSE commands)
  • heating systems (control temperature, set heating level)
  • alarms (both interior/external)
  • pods
  • action groups (scenarios which can execute predefined Tahoma group of steps, e.g. send to all roller shutters DOWN command, one by one)

Both Somfy Tahoma and Somfy Connexoon gateways have been confirmed working.

Discovery

To start a discovery, just

  • install this binding
  • open Paper UI
  • add a new thing in menu Configuration/Things
  • choose SomfyTahoma Binding and select Somfy Tahoma Bridge
  • enter your email (login) and password to the TahomaLink cloud portal

If the supplied TahomaLink credentials are correct, the automatic discovery starts immediately and detected roller shutters, awnings, switches and action groups appear in Paper UI inbox.

Thing Configuration

To manually configure the thing you have to specify bridge and things in *.things file in conf/addons directory of your openHAB 2.x installation. To manually link the thing channels to items just use the *.items file in conf/items directory of your openHAB 2.x installation. To retrieve thing configuration and url parameter, just add the automatically discovered device from your inbox and copy its values from thing edit page. (the url parameter is visible on edit page only) Please see the example below.

Channels

Thing Channel Note
bridge N.A bridge does not expose any channel
gateway status status of your Tahoma gateway
roller shutter, screen, venetian blind, garage door, awning, window, pergola control device controller which reacts to commands UP/DOWN/STOP + closure 0-100
venetian blind orientation percentual orientation of the blind's slats, it can have value 0-100). For IO Homecontrol devices only (non RTS)
action group execute_action switch which reacts to ON command and triggers the predefined Tahoma action
onoff, light switch reacts to standard ON/OFF commands
smoke sensor, occupancy sensor & contact sensor contact normal value is CLOSE, changes to OPEN when detection triggered
light sensor luminance light luminance value in luxes
pod cyclic_button_state pod cyclic button state
pod battery_status_state pod battery status state
pod lighting_led_pod_mod_state lighting led pod mod state
interior alarm alarm_command used for sending commands to Somfy alarm device
interior alarm intrusion_control used for alarm external intrusion controlling
interior alarm alarm_state state of the Somfy alarm
interior alarm target_alarm_state target state of the Somfy alarm
interior alarm intrusion_state intrusion state of the Somfy alarm
external alarm active_zones_state state of external alarm active zones
door lock lock switch representing unlocked/locked state
door lock open switch representing open/close state
on/off heating system target_heating_level target heating level (off, eco, comfort, frostprotection)
heating system current_temperature current temperature of the heating system
heating system current_state current state of the heating system
heating system target_temperature target temperature of the heating system
heating system battery_level battery level of the heating system
temperature sensor temperature temperature reported by the sensor

When roller shutter-like thing receives STOP command two possible behaviours are possible

  • when the roller shutter is idle then MY command is interpreted (the roller shutter/exterior screen/awning goes to your favourite position)
  • when the roller shutter is moving then STOP command is interpreted (the roller shutter/exterior screen/awning stops)

Awnings, garage doors, screens, blinds, and windows things have the same notation as roller shutters. Just use "awning", "garagedoor", "screen", "blind" or "window" instead of "rolleshutter" in thing definition.

Alexa compatibility

This binding is compatible with the official Alexa Smart Home Skill. Since Rolleshutter items are unsupported, only Dimmer with control channel can be used. Syntax in .item file is as follows:

Dimmer RollerShutterLivingD "Roller shutter living [%.1f]"  [ "Lighting" ] {channel="somfytahoma:rollershutter:237dbae7:87bf0403-a45d-4037-b874-28f4ece30004:control"}

Alexa can set the roller shutter (awning, blind, ...) to a specific position as well as send ON (interpretted as UP) and OFF commands (interpretted as DOWN).

Version: 2.4
