Is it possible to combine the FBs with 2 sets? For example, switch on 1/2/3/4 with 1 FB in the kitchen and switch off 1/2/3/4 with the other FB in the bedroom?
From my experience...if the receivers are too close together, the remote control cannot separate them clearly. This means, for example, that receiver 1 and 3 switch even though only receiver 1 was pressed.
