<p class='note warning'>
**This platform has been deprecated in favor of a "[climate](/components/climate.knx/)" platform and will be removed in the future. Please use the climate platform.**
</p>
The `knx` thermostat 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:
```yaml
thermostat:
- platform: knx
name: KNX Thermostat
temperature_address: 0/1/1
setpoint_address: 0/1/0
```
- **name** (*Optional*): A name for this devices used within Home assistant
- **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) (see http://www.knx.org/fileadmin/template/documents/downloads_support_menu/KNX_tutor_seminar_page/Advanced_documentation/05_Interworking_E1209.pdf)
- **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.
With the current version of the module, no advanced KNX thermostat functionalities (e.g. HVAC mode) are supported.
