- dimming actuators
|

- LED controllers
|

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/light 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.

Many KNX devices can change their state internally without a message to the switch address on the KNX bus, e.g., if you configure a scene or 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` (in most cases from the light actuator), it will overwrite the state of the switch object.
|
||||
|
||||
For switching/light actuators that are only controlled by a single group address and don't have dedicated state communication objects you can set `state_address` to the same value as `address`.
|
||||
|
||||
*Note on tunable white:* Home-Assistant uses Mireds as the unit for color temperature, whereas KNX typically uses Kelvin. The Kelvin/Mireds relationship is reciprocal, not linear, therefore the color temperature pickers (sliders) in Home-Assistant may not align with ones of KNX visualizations. This is the expected behavior.
