Not controlling it with any software for now. I originally programmed the modules addresses and dim rates to 100% at 0 secs (because I'm using non dimmable CFL's until compatible dimmable CFL's are available). I'm just controlling the lights using the wallplate switches and the lights flicker. Can't determine whether the problem is coming from the powerline, something within the internal circuit (it's a new empty house with only a computer plugged into the power circuit) or if the modules themselves are the problem. I will try using an incandescent light to see if it also flickers which I expect it won't.
