If you can’t get them to work at all, you are probably having a “bridge” problem. Try plugging the IR543 into another plug on the other side of the room or in a different room. This may help since a different plug may be on the same side of your circuit box. You could turn your cloths dryer on and try it. This will sometimes connect the phases of your electrical system through your dryer. If it works, you could leave your dryer on all the time, connect the phases of your electrical system or use another plug that works with the lights (if you can find one). You may also be having a noise problem. If you have any surge protectors, unplug them then try the lights. I know for a fact that Panamax surge protectors are bad for stopping X-10 signals and require a plug in filter to allow the X-10 to work. If it still doesn’t work, you may be having an X-10 IR code problem. I have seen some instances where the IR543/pronto combo will only send out unit codes but no command (on/off/dim/bright). Try using the X-10 direct on/off codes or double the on and off commands in the macro.
