The `knx` light component is used as in interface to switching/light actuators.
|
|
|
|
The `knx` component must be configured correctly, see [KNX Component](/components/knx).
|
|
|
|
To use your KNX light in your installation, add the following lines to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
light:
|
|
- platform: knx
|
|
name: Kitchen-Light-1
|
|
address: '1/0/9'
|
|
brightness_address: '1/0/11'
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **name** (*Optional*): A name for this device used within Home Assistant.
|
|
- **address**: KNX group address for switching the light on and off.
|
|
- **brightness_address** (Optional): KNX group address for dimming light.
|
|
- **state_address** (*Optional*): separate KNX group address for retrieving the switch state of the light.
|
|
- **brightness_state_address** (*Optional*): separate KNX group address for retrieving the dimmed state of the light.
|
|
- **color_address** (*Optional*): separate KNX group address for setting the color of the light.
|
|
|
|
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.
