What is controlling your ALC switches? Do you find it to be fast enough for scenes involving 10 or more switches? The fact that my "Basement all-off" scene turns all of the lights off within milliseconds of each other makes me think that the ALC protocol isn't the problem. I suspect that my OmniPro (Aegis 2000 really) or its bundled ALC controller is just too slow at processing the commands.My alc switches are not 8 years old. Maybe thats why I have not had one single problem mentioned above. Never fails, never breaks. Always works. Wouldnt consider anything else for my next house than ALC. Although, Vantage is looking appealing now after reviewing it last week.
Are you able to control a single CFL bulb with one of your ALC relays? I think they fixed this problem with their relay switches sometime around 2002. They also didn't have any of the ALC scene switches or quad aux switches back then - just dimmers, relays, and single aux switches
