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

The knx component must be configured correctly, see KNX Component.

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

# Example configuration.yaml entry
climate:
   - platform: knx
     name: HASS-Kitchen.Temperature
     temperature_address: '5/1/1'
     setpoint_shift_address: '5/1/2'
     setpoint_shift_state_address: '5/1/3'
     target_temperature_address: '5/1/4'
     operation_mode_address: '5/1/5'

Alternatively, if your device has dedicated binary group addresses for frost/night/comfort mode:

# Example configuration.yaml entry
climate:
  - platform: knx
    name: HASS-Kitchen.Temperature
    temperature_address: '5/1/1'
    setpoint_shift_address: '5/1/2'
    setpoint_shift_state_address: '5/1/3'
    target_temperature_address: '5/1/4'
    operation_mode_frost_protection_address: '5/1/5'
    operation_mode_night_address: '5/1/6'
    operation_mode_comfort_address: '5/1/7'

If you want to overwrite the supported operation modes use:

# Example configuration.yaml entry
climate:
  - platform: knx
    name: HASS-Kitchen.Temperature
    temperature_address: '5/1/1'
    setpoint_shift_address: '5/1/2'
    setpoint_shift_state_address: '5/1/3'
    target_temperature_address: '5/1/4'
    operation_mode_frost_protection_address: '5/1/5'
    operation_mode_comfort_address: '5/1/7'
    override_supported_operation_modes:
      - "Night"
      - "Standby"
      - "Comfort"

operation_mode_frost_protection_address / operation_mode_night_address / operation_mode_comfort_address are not necessary if operation_mode_address is specified.

override_supported_operation_modes is an array that can contain any of the following values:
