The `knx` climate platform is used as in interface with KNX thermostats.
The `knx` component must be configured correctly, see [KNX Component](/components/knx).
To use your KNX thermostats in your installation, add the following lines to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
climate:
- platform: knx
name: HASS-Kitchen.Temperature
temperature_address: '6/2/1'
setpoint_address: '5/1/2'
target_temperature_address: '5/1/1'
operation_mode_address: '5/1/3'
```
Alternatively, if your device has dedicated binary group addresses for frost/night/comfort mode:
```yaml
# Example configuration.yaml entry
climate:
- platform: knx
name: HASS-Kitchen.Temperature
temperature_address: '6/2/1'
setpoint_address: '5/1/2'
target_temperature_address: '5/1/1'
operation_mode_frost_protection_address: '5/1/3'
operation_mode_night_address: '5/1/4'
operation_mode_comfort_address: '5/1/5'
```
Configuration variables:
- **name** (*Optional*): A name for this device used within Home Assistant.
- **temperature_address**: KNX group address for reading current room temperature from KNX bus.
- **target_temperature_address**: KNX group address for reading current target temperature from KNX bus.
- **setpoint_address**: KNX group address for basis setpoint
- **operation_mode_address** (*Optional*): KNX address for operation mode (Frost protection/night/comfort).
- **operation_mode_state_address** (*Optional*): Explicit KNX address for reading operation mode
- **controller_status_address** (*Optional*): KNX address for HVAC controller status (in accordance with KNX AN 097/07 rev 3)
- **controller_status_state_address** (*Optional*): Explicit KNX address for reading HVAC controller status
- **operation_mode_frost_protection_address** (*Optional*): KNX address for switching on/off frost/heat protection mode.
- **operation_mode_night_address** (*Optional*): KNX address for switching on/off night mode.
- **operation_mode_comfort_address** (*Optional*): KNX address for switching on/off comfort mode.
`operation_mode_frost_protection_address` / `operation_mode_night_address` / `operation_mode_comfort_address` are not necessary if `operation_mode_address` was specified.
