I have been controlling my outdoor lighting via X10 wall switch modules for many years via plug-in timer/controllers with no problems/issues whatsoever. Since getting the WM100, I've experienced numerous instances of individual lights not turning on as scheduled, lighting on schedule but not turning off, etc. I had started out with all 3 lights set on unit address 1 to turn on and off together, as I had for years. But one or more lights did not turn on or off consistently, so I changed each light to its own individual address, and after some experimenting with different combinations, I've achieved modest improvement. My current status is that the lights set on unit addresses 2 and 5 turn on and off as scheduled. The light on address 8 turns on per schedule but does not turn off. All 3 lights respond well to discrete on/off commands via the iOS app, so the signals are getting through OK. Any ideas?
