I have this adapter plug currently in my aquarium for switching the lighting operates in conjunction with the FHEM. What can I say, works great. I'm going to soon be another connector set for the washer and the dryer, for example. And my TV and stereo components in the living room I will soon be equipped with it. If the price were not so high, I would certainly provide more vil more things with it. The one point deduction, there is for the price. I think 35 EUR would do it ...
