Telldus Tellstick

Below is an example of how to capture events from Telldus Tellstick and forward them to the openhab bus as events through REST. The example works for on/off switches and wireless sensors but can easily be extended to dimmers, etc. Events are sent to openhab regardless if a telldus state change originates from a wireless remote or from other software (e. g. Switchking or Telldus Center). In other word, the script keeps openhab in sync with telldus states.

You need:

• Tellstick Duo (RF Transmitter/Receiver)
• Telldus Core software from here: http://developer.telldus.se/
• Tellcore Python lib: https://pypi.python.org/pypi/tellcore-py

See wiki section Binding configurations for the outbound example (openhab to tellstick).

Tested on Ubuntu Server 13.04.
