Dave W, Wasnt thinking about the NEW Transformer, Was thinking of the lightening strike that blew the Transformer and sent a surge through my wiring, Well anyway just looking at motives, because everything had been working fine until a few weeks ago and so far I have found the eco-i-light had gone bad and was sucking x10 signal, then found a led night light in my daughters bedroom that was also blocking signal, moved CFL blubs around trying to get them off the troubled circuits, unplugged cell phone transformers that weren't being used, etc. etc.
I'm not using the RR501 anymore, But put a TM751 on the same circuit as the couch lamps and the porch lights and thats the reason I can control the couch/porch lights with an RF signal but for some reason something is still sucking up the signal via the CM15A, I thought it was the CFL bulbs in the bedroom lamps so I removed them and I had control of the couch lamps again with the timers, then last night and today the timers didnt turn on or off the couch lamps, as far as I know nothing has been changed or added this weekend that would be blocking the x10 signal so I guess just like eco-i- light its getting worse day by day so I'm just waiting for it to go out....
