I have an OP-IIe controller that controls my security, HVAC, and a small system of Simply-Automated UPB devices. Less than 20. Everything has been bullet-proof for years, then one day my lighting control stopped working. Everything else is fine. I can control every lighting device from the wall switch and from UpStart, as designed. I can also operate the first light in the system (Kitchen Main) from Snap-link and from the HAI panel. But nothing after that works with Snap-link. Also, I have very high signal strength and very low noise at every device. Even though I can operate one of the devices, I have assumed that the PIM was in good working order, but it was recently recommended that I should swap this out. It is an HAI PIM. Does this seem reasonable, or could something be messed up in the PCAccess programming, even though I have not changed anything in years.
Please keep in mind that I don't work on this on an everyday basis, so I consider myself a novice relative to you folks. So keep that in mind with your response. TIA
