If I move the ir543 to a different room(different circuit) all the switches work. In my den(where I need it) the ir543 only the leviton switches work. Will the amplifier coupler solve my problems? Is there IR to much IR noise in the den(all my AV equipment)? I really like the switchlincs, but I want to be able to control everything from my Pronto. One other question, Smartlinc came out with a flourescent switch, can I use that for on/off for my ceiling fan and be able to control the speed with the pull chain on the fan?
