The sockets was delivered in such a small box that you might think it would be only one outlet in the box. But there are in fact three sockets, a description and the hand-held transmitter. The sockets are so compact that they do not stand out in the apartment. The transmitter functions reliably. The switching capacity should be taken into account! Maximum 1000Watt. Now at Christmas time are the outlets with a "click" to switch on the Christmas lights, since I put the house and socket code on a button. When Christmas is over, then comes back to the RaspberryPi turn, because there I have a 433MHz transmitter, and the sockets can turn with it. Then each outlet gets its own code again. Can set Easy on the back of the socket is yes, jumper pin is the supply by!
