"Beware that this remote control extension only allows you to control all 4 sockets on-off in one go. It does not allow you to control the 4 sockets separately. Although the remote control has 4 separate on-off button, you cannot use them to control the 4 sockets separately. You can only program one of the button to control the entire panel. I was misled by the picture and have now refunded it.
Note: there is no battery included in the remote and so you will need to buy those special A32 battery from some other places."
