The Z-Wave doorbell consists of a wireless doorbell and a bell button which acts as a controller and transmitter. By pushing the bell button it starts to light up and sends a radio signal to the doorbell, which also lights up and plays one of five eligible ringing tones. In addition to these five stored ringing tones it is possible to record own tones as a Wav file.
While the door bell bundle works well together and the bell alone and easily be integrated in IP Gateways the button controller can not be operated as secondary controller. Solution: Use different controller to control the door bell.
