I have just run across the same situation on all my wall switches. Last month they worked with remote, manually, and with the software. Then, I installed the dryer phase coupler (4826A Coupler - Repeater) last week to fix other issues I had, and now all of a sudden, the dimmers do not work with remote or the software (I have the latest AHP software with myHouse, OnAlert).
To be more specific, I can still manually dim the lights at the switch. However, if I use the software to dim the light to 50%, it begins to dim, and then drops to say 7 or 8%. If i try to dim it again by clicking at 50% on the software, it shoots up to 100%. The remotes do not dim the lights at all now.
Any ideas (since it seems that the phase coupler was not the issue in the first place...and obviously I can't simply remove it since I need it to fix the phase issue I have). Could it be that the coupler I got (which was pretty $$$) is also a repeater and maybe I should have cheaped out and just got the coupler with no repeater?
Anyone else seen this problem?
