KNX Switch

The knx switch component is used as in interface to switching actuators.

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

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

switch:
  - platform: knx
    name: Kitchen.Coffee
    address: '1/1/6'

• name (Optional): A name for this device used within Home Assistant.
• address: KNX group address for switching the switch on/off
• state_address: (Optional) separate KNX group address for retrieving the switch state.

Some KNX devices can change their state internally without any messages on the KNX bus, e.g., if you configure a timer on a channel. The optional state_address can be used to inform Home Assistant about these state changes. If a KNX message is seen on the bus addressed to the given state address, this will overwrite the state of the switch object. For switching actuators that are only controlled by a single group address and can’t change their state internally, you don’t have to configure the state address.
