KNX Thermostat


The knx climate platform is used as in interface with KNX thermostats.

KNX thermostats use at least 2 group addresses: one for the current temperature and one for the target temperature (named set-point in KNX terms).

To use your KNX thermostats in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
climate:
  - platform: knx
    address : KNX_ADDRESS
    temperature_address: 0/1/1
    setpoint_address: 0/1/0
  • address (Required): The KNX group address that is used to turn on/off this actuator channel.
  • temperature_address (Required): The group address that is used to communicate the current temperature. Data format must be datapoint type 9.001 DPT_Value_Temp (2-Octet float value), check details.
  • setpoint_address (Required): The group address that is used to set/read the target temperature. Data format must be datapoint type 9.001 DPT_Value_Temp (2-Octet float value). Make sure, you set the read-flag for the thermostat to allow Home Assistant to read the target temperature.
  • name (Optional): A name for this devices used within Home Assistant.

With the current version of the module, no advanced KNX thermostat functionalities (e.g. HVAC mode) are supported.
