Hi. I have had several Centralite Zigbee in-wall light switches working perfectly in my house since day one of buying my ST hub. Yesterday, I added 2 new switches. Prior to pairing they worked fine. I could press the switches and the lights connected to them would turn on and off as expected. This morning, I paired both switches to the ST hub and after pairing them, only one would still allow me to press the switch to control the lights. They both paired fine and could be controlled via the ST app, but one was not able to be controlled manually (physical button press) any longer. If i defaulted the switch in question I’d regain manual control again. Pair it, lose control except through the app.
Sooooo, I figured maybe something was funny with that switch and I swapped it for another one I had. This time, the replacement switch worked manually AND through the app. I figured, problem solved! Not so much…about an hour later my daughter asked why the hall light switch stopped working (this one has been in since day 1 with no troubles). Sure enough, no manual control, but app control. So basically, I killed manual control of that switch by pairing the other!?
After some digging online I found someone else in a different HA solution had the same issue. Support for that product suggested “deleting the binding for that switch.” The customer stated they did and got it to start working again.
My question is, a)why did the first switch struggle with manual control, (b) why was the replacement able to pair and work as expected, and © why did pairing that replacement switch cause the hall light switch to fail for manual control? For what it’s worth, I was able to swap THAT switch for another one which paired and worked manually and through the app but THEN another Zigbee switch stopped manual control! Why are these switches knocking out other ones that were previously working perfectly?! Thanks!
