Around 4:00 EST yesterday, all ZigBee in my setup went kaput. I have 10 SmartThings Moisture sensors, 3 Kwikset locks, and 5 Peanut plugs. None of them work now and are marked “offline” in the IDE. Generally has worked well for the past several months, so I’m having a hard time troubleshooting this one.
So far I’ve done the following:
(1) Determined ZigBee channel was 15. I hardcoded my wifi channel to 11. I don’t think interference was an issue since it worked without issue for months, but went ahead and did this after reading other posts about ZigBee devices going offline
(2) Hub is connected to a network switch, nowhere near my router or any access points. Just pointing this out because I know this can be another source of interference.
(3) Unplugged and removed batteries from my hub for twenty minutes and then plugged everything back in. I did this 14 hours ago and don’t see any improvement.
(4) Tried removing and replacing batteries on the sensors didn’t help (flashes red and green now). Removing and replacing the Peanut plugs had no effect either.
(5) I have two new Peanut plugs that I never paired before. Tried to include those and that didn’t work (i.e., nothing happens on the add device screen)
(6) Checked the ZigBee status in IDE and the state is “Functional”
(7) Health check is turned off (and has been off)
(8) Contacted support this morning
Is there anything else I can do that I haven’t covered above?
I’m completely baffled by this issue. I’ve had SmartThings for about 5 years (4 at an old house and 1 at my new house). My setup is mostly z-wave which continues to work fine. I’ve had the usual problems over the years that everyone complains about, but I can usually resolve those with resets, power cycling, repairing, etc. Never had such a large-scale failure though. Really hoping that the ZigBee module/antenna did not die…
Thanks for any advice!
