I have an X10 dimmer switch in my bedroom. Initially, it operated fine, 
no troulbe to speak of. Then, "all of a sudden", it started randomly 
turning on the main room light in the middle of the night.

I didn't notice this for a while, mainly because it doesn't bother me 
unless I'm already awake. But my wife mentioned that it wakes her up and 
she has to get up to turn it off. (The remote switch seems to have give 
out, but that could be the battery.)

I am remembering now, that one day I got mad at the power blinking out 
so I brought in a heavy duty (well, at least heavy, two part, average 
geek would only want to move one piece at a time) UPS for my asterisk box.

Could this be a symptom of the interference you spoke of?

What filters have you used?

Thanks.
