Okay here goes..... I have 6 recessed lighting fixtures and they are all on the same circut, with 2, 3 way switches..... I recently purchased 6 of the screw in the socket type of X10 controllers, sl575. I want to control the 4 at the front of the room and then the 2 in the back of the room. Dim the front 4 to off and dim the rear 2 to a low level. Anyway I don't seem to be able to get them to work at all.... Can I do this???? Is my problem related to the Bridge refered to in the forum????? I have all of the addresses set correctly and I am using a ir543 to control them. Thanks ahead of time.
