I finished off my basement a few years ago. I thought it would be cool to add a little high tech flash, so I put all of the basement lighting on X10. It was nice because I only had to run one wire to a bank of X10 dimmer switches that lets me adjust all the lights from a single spot. Cool.
Until a few months ago.
Now my lights turn on and off by themselves, and I don’t know how to diagnose the problem. I cannot think of any new electronic devices in my home…my assumption is that some signal is coming in from outside the house. It started with one particular light, then over the subsequent weeks the other lights in the basement started turning on and off by themselves. A light may switch on or off every 15-30 minutes now.
Maybe my house is haunted. Nah, that’s a stupid theory.
Do I need a Whole House Blocking Coupler? I’m reluctant to spend $75 and rip into my main breaker box based on a hunch. Is there any way to know what is causing this problem before I start buying new devices?
