After I set up a new device with my Logitech Harmony One (Any kind of CD player, but could be anything) I could teach the Funksteckdosen with the codes of the CD player. Now start with the first of Harmony imaginary CD player, making the wireless socket gets to turn on the signal before the other devices are set up. Finally I can take with one keystroke the entire facility into operation with a remote control! The cable of the receiver is long enough to make the sight even from behind the closet can. A great thing!
