Purchased a home in 2012. The previous owner had installed several X10 transmitters with the xp4d-w switches on them.
One controlled my kitchen lights and has worked fine (after I figured out how to use it
The other one controls my foyer light and the two outside porch lights. Last week my lights starting simply blinking (fast) and the switch wouldn't dim them or turn them off - in other words I lost complete control of my outside lights. I've had to 'unscrew' the bulbs to get them to stay off.
Not knowing what I'm doing, I purchased a replacement switch (Xp4d-w) and of course, nothing works on it now (won't control anything).
So, I know at some point I have to program something somewhere, but am not even sure if it was the switches failure (since the other light (foyer) on the switch continues to work just fine as well as dimming, etc).
Help? Suggestions?
