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.
