Hi all,
First post here, though I've been lurker for answers to problems often.
I have an X10 home automation setup that was working like a champ 6 months ago. 3 lamp modules (2 plug in, 1 wall socket), security system, AHP. Everything was working fine, after I added the above signal coupler to bridge the phases back in 2006. Since then I added some noise filters to improve signal reception on the power lines. Then about 6 months ago I replaced the lamp modules (1 of which is on the opposite phase from AHP and the other one) with mechanical timers as I wanted to go to CFL lamps. I planned to get appliance modules to replace them, but it took me a while.
Anyway, I get the appliance modules in and they work fine on the primary phase, but the one on the other phase will not trigger there. It works fine on the same phase as the AHP transceiver. No new appliances since then, so I don't suspect a new noise villain. The Smarthome Signalinc plug-in coupler is 30 months old, so 6 months past warranty. I opened it up (easy to do) and everything looks fine. Nice heavy wiring and nothing burnt or out of place.
Do these things go bad quietly, or do they fail spectacularly? I've checked the system quite a bit, but I'm looking for ideas on things I might have missed.
Thanks!
