In the list of supported devices of zigbee adapter I found a switch of Paulmann. After the friendly postman delivered the order I determined that I have ordered the wrong part. The supported switch has the article number 500.44 (dimmable switch) and I have ordered 500.43 (non-dimmable).

But I tried to pair the switch with the zigbee adapter, but not successfully, device was unknown. I tried to solve this problem by contacting the community....
