 ## Exposing entity states, entity attributes or time to KNX bus
 
 KNX integration is able to expose entity states or attributes to KNX bus. The integration will broadcast any change of the exposed value to the KNX bus and answer read requests to the specified group address. It is also possible to expose the current time.
