OK folks...this is a strange one. First off, let me say that I have not started the "real" problem diagnosing yet...that will be either tonight or this weekend.
I have PCS UPB switches throughout my house. I probably have 100+ switches and they were installed about 6 months ago. The switches are a mixture of keypads, Dimmers, and Slaves.
PROBLEM: During the night, and sometimes during day, I can hear a buzz from every switch. And...(fasten your seatbelts, folks)...lights that are on will begin to fade up and/or down quickly. Lights that were off will turn on. My wife says this occurs during the day but I've only seen this at night.
The problem begins usually after midnight and generally stops by 7am (times are rough guesses). Last night was a prime example. I started hearing the buzzing around 12:30am. Somewhere around 2am I notices lights on outside of my bedroom. It was the foyer chandelier and the laundry room light. I got up and turned them off...went to the bathroom...and they were back on. And they were flickering (or dimming up and down quickly).
I went to the gym from 6:30am to 7:30am. When I left the problem was still happening. When I returned at 7:30am the problem was gone...no flickering...no buzzing...nothing.
My first guess is a bad switch somewhere. But I can't figure out why the problem shows up mostly at night.
If the problem occurs this evening then I'll start diagnosing it...but I've never seen it occur before midnight. And I gotta sleep! I may have to wait until Friday night to start on this.
Anyone have any ideas to help my start diagnosing this? Oh, I have not [yet] run UpStart to look for noise. Also, I do not keep my PIM connected so it's not that.
Once it occurs again I figured I would start turning off breakers and see if I can isolate an area with a possible bad switch.
