If you have done it once, to program the radio-controlled sockets, everything works perfectly - even from a greater distance. However, the manual is a joke. This set is the third that I bought (various manufacturers). And I've never had problems with the commissioning. After endless tinkering is then succeeded somehow. If you stick strictly to the instructions, nothing happens. But as I said, boldly push the buttons, at some point it goes click audibly and then the system switches properly appliances on and off.
