The tellstick component integrates TellStick devices into Home Assistant. This integration allows users to add switches, lights, and sensors which are communicating with 433 MHz. There are a number of vendors (Capidi Elro, Intertechno, Nexa, Proove, Sartano, and Viking) who are selling products that work with TellStick. For more details, please check the TellStick protocol list.


To get started, add the devices to your configuration.yaml file.

# Example configuration.yaml entry

For users there is a TellStick add-on available.

# Example configuration.yaml entry for with the TellStick add-on
  host: core-tellstick
  port: [50800, 50801]

Configuration Variables


(integer)(Optional)Because the TellStick sends its actions via radio and from most receivers it’s impossible to know if the signal was received or not. Therefore you can configure the switch and light to try to send each signal repeatedly.

Default value: 1


(string)(Inclusive)If you run TellStick on another server or with the add-on.


(list)(Inclusive)Needed with the host configuration variable. Must be port pair, for example [50800, 50801].
