Lighting & Power
Lightbulb
Use the Lightbulb accessory to control lights. Depending on the type of light, select the appropriate channel setting.
Channel Settings
The Lightbulb accessory supports four channel settings. Each one requires different KNX group addresses depending on the capabilities of the light.
Switchable
For lights that can only be turned on and off.

INFO
HSV Color (DPT 232.600) is a single 3-byte datapoint that carries hue, saturation, and brightness in one value. A separate dimming address is not needed because brightness is already included in the HSV value.

Implementation Tip
We recommend implementing a garage in KNX with a relay actuator that sends a short impulse, and a binary input connected to a reed contact that closes when the garage door is fully closed.
If you measure the time the garage needs to fully open, you can add this turn-off delay to the binary input to get an "open" notification in the app only after the door is physically open.
