I have been using X10 wall switches and outlets for about 6 months now and have come to the conclusion that it is a waste of time and unsafe. Outdoor spotlights would come on when we wash clothes. Garage lights would come on at times when running the clothes drier. After trying multiple addresses and finding the same results, I yanked out all the X10. It is a waste of time and a system as unreliable as this should not even be marketted. Anyone looking for lots of headaches, I have lots of X10 crap for sale at a really, really good price.
