This radio-controlled sockets are a useful technical relief which helps to save electric energy by using them makes sense. The idle consumption I have not yet measured. The outlet is slightly warm, so consumed something for their own operational readiness. The gear changes are perfect after it has adjustment of doses and the two remote controls performed correctly. Here you have to think a little and requires a screwdriver. That "house code" or similar bedeitet that you have to bring this series of four plus two remote controls on a common attitude that one can choose is important. Apparently you can use as another four sets independently. Then each of the 4 doses must be given a unique number and you're done. I would recommend this product very well to control lamps with plugs and foot.
