I just installed several wall switches (Powerhouse) and all work fine save one. It will turn on from the switch but not from the remote or pc controller (Home Director). When turned on at the switch however, it will turn off from the remote and the pc. I swapped the switch with one that tested ok and got the same result. I have installed a Leviton phase coupler and all the other modules in the house work fine. Small house (<2000 sf). Any suggestions?
