Great, very reliable function and simple coding, so the simplest wireless pairing between the transmitter (wall or hand-on / off) and receiver (REDIAL. Socket between the socket o. Hardwired version)! In fact, the compatibility promises the manufacturer is maintained properly with all other products of this series, where I (because of bad experience with a competitor's product) was initially quite skeptical about this statement. The radio adapter socket used in combination with this switch by me do not even need a special setting of coding options on the transmitter (even if, as this can be similarly called by removing the switch cover and the underlying [. "DIP switches", oa scherzh . "Mice piano" called] Wählrastern, very easy carry). The pairing is done in my case, by only simple operating the on switch within the first 5 seconds after plugging the receiver into an electrical outlet - that's what you want ?! The only complaint is, to my regret, unfortunately the form or size incompatibility with existing, conventional switch / socket combinations from the hardware store, so I for one star rating depart! Too good would have been if the wireless wall switch had integrated into existing switch combinations can be with! Perhaps there is even compatible form, conventional switches? This look, or exchange them for existing, existing series, although I consider as most perfect solution - but yet too expensive and a bit exaggerated ...
