Need X10 help. I am trying to control x10 wall modules using and ir543 and x10 remote. Results are sporadic at best. I read on line about phase coupling problems, noise on the power lines, and power sucking that can all cause problems. I don't quite understand all this information. I need to determine definitively the exact cause of my problem or problems before I can start working on a solution. How can I figure out exactly what is causing my poor x10 performance? Just for the record sending x10 ir signals to the ir543 and pressing directly on a command button on the ir543 both produce the same results which is poor at best. Thanks for any help.
