I started getting "send failed (no acknowledgment)" on certain inline relays with sense. I tried to replace the devices but the new ones are not being seen either. Most of the relays in same breaker work fine, but two of eight fail 100% of the time, while a third is 50/50. The buttons on the relay turn the lights on and off fine. This system has worked fine for over a decade. No work was done on it recently Any ideas how to diagnose? I assumed replacing device would work, but it didn't. Seems like some kind of interfercance, but not sure why some circuits in same breaker work and some don't?
