I once was on the X-10 kick and used them in every room in the house. Placed a motion sensor in the hall and bathroom to turn on the lights at night. Hint do not place a motion sensor were you rely on it to see. Do not work very well when you are in the shower or well you get the idea. Lasted one day in there. Friends thought it was cool anyway. Great stuff but after awile you get to were you just want to flip a switch.
