Im working with an older HomeWorks QS system that has both wired and RF devices on it. Recently several wired HWD-8ANS switches (sconces and deck lights) stopped responding to commands from wired 6 button keypads throughout the house. These two switches are only part of the entire scene assigned to this keypad button (exterior lights) and the rest of the devices assigned to exterior lights, all of which are wired HWD-8ANS's, work just fine. The two switches work when they are physically activated so they are getting power and technically function. Ive gone into programming to try reprogramming the exterior lights button but when I try assigning loads the sconce and deck light switches say they are not communicating or connecting to the processor despite being physically connected to it and other wired devices on the same QS Link working just fine. Ive been on the phone with tech support several times, and they weren't able to help. Any and all help is very much appreciated!
