I purchased the AHP w/CM15A interface. So far most of the WS467 wall switches will only turn off, but not on. I would guess a noise problem. But, I just install a WS4777 wall switch with to CS277 companion switches. Again, the light will only turn off from AHP, but also I cannot get the light to turn on locally from the companion switches. They will turn the light off, but not on, and the SW4777 will turn the light both on and off locally. Anyone have any ideas where I should look, or is should this be piled into that ol' noise problem bin.
