Good solution with no holes in the wall

This switch is especially recommended where you want to put any installation can, for example, because it would include running lines or impair the statics. It is so light that it stops the wallpaper with commercial Power Band - assuming this is well glued. Screws can be him of course, which is still less work is auszustemmen as a can opening. Of course, one also needs a switching relay from the HomeMatic series. The switch has only the function to transmit a radio signal and to acknowledge the execution by the switching relay.

The process of programming each component is well described in the instructions and goes quickly out of hand. It is operated with me about the HMLAN interface on the PC, so I can not tell you how he works directly with a receiver or with the HomeMatic CCU. Initially, I had the problem that the indicator is always lit red only. After any update of the software but now light up green all the switches, as originally planned. On the switching function of this behavior had no effect.

The batteries last for not really frequent use long, I had to at day 3-6 switching operations not change after one year. Transmission problems there despite several partitions have hardly. Very rarely I had to press several times to trigger the switching process - perhaps an interference signal the reason or the interface was briefly overloaded because I so pursuing some HomeMatic components.

Remain only to mention that you stated for the purchase of this switch to the HomeMatic system that is compatible with my knowledge no other home automation system. But it has in my opinion a good compromise between functionality and price, and there are a variety of applications.
