Newer models of the iRobot Roomba no longer move randomly through rooms, but track next to track. To do this, the camera must orient itself to the ceiling. This works best with a little light.
This applet helps the Roomba by switching on the light when the hoover starts.
The applet sends the start information to the Timberwolf Server. The server switches on the light when it is dark. Via KNX, but also via DMX, 1-Wire, MQTT, HTTP-API etc.
