# Somfy Tahoma Binding

This binding integrates the Somfy Tahoma (opens new window) and Somfy Connexoon (opens new window) 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)
  • gates (control gate, get state)
  • 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)
  • dimmer lights (light switches with intensity setting)
  • light sensors (luminance value)
  • occupancy sensors (OPEN/CLOSE contact)
  • smoke sensors (OPEN/CLOSE contact, alarm check)
  • contact sensors (OPEN/CLOSE contact)
  • temperature sensors (get temperature)
  • electricity sensors (get energy consumption)
  • door locks (LOCK/UNLOCK, OPEN/CLOSE commands)
  • heating systems (control temperature, set heating level)
  • valve heating systems (control temperature, derogation mode and temperature)
  • exterior heating systems (set heating level)
  • alarms (both interior/external)
  • pods
  • docks (battery info, siren control)
  • sirens (battery status full/low/normal/verylow, siren control ON/OFF, setting memorized volume)
  • action groups (scenarios which can execute predefined Tahoma group of steps, e.g. send to all roller shutters DOWN command, one by one)
  • thermostats (read status and battery level)

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

# Discovery

To start a discovery, just

  • Add a new Somfy Tahoma bridge thing.
  • Configure the bridge with your email (login) and password to the TahomaLink cloud portal.

If the supplied TahomaLink credentials are correct, the automatic discovery can be used to scan and detect roller shutters, awnings, switches and action groups that will appear in your Inbox.

# Thing Configuration

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.

# Remarks

All things which have a RSSI (relative received signal) state, expose a channel "rssi".

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

  • 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)

If you want to set the MY position of a roller shutter and you don't care the possible movement, try sending the MOVE command (OH2 does not know MY, so it stands for "move to MY position")


Blinds and adjustable slats roller shutters can control their closure and orientation by sending a comma separated string consisting of closure (0-100) and orientation (0-100) to the "closure_orientaion" channel.

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).
