Have had my thermostat loose connection a couple of times now. Don’t remember what was going on the first time, but this time it occurred after the new firmware update. The first time, the only way that I could get it to reconnect was to remove the thermostat from the Wyze app and re-add it. A pain in the ass! Last night that wasn’t even working. Just sat there and said pairing.
Okay, here is what finally worked for me and maybe try it before removing the thermostat. Go into settings, apps, go to the Wyze app and Force Stop it. I did it twice just to make sure it stopped. Reopened the Wyze app and it was working.
BTW, I am using an android phone and am on Spectrum with their Technicolor modem/wifi router.
Hope this works for everyone and maybe it will give the Wyze Support Crew an insight into the problem.
Let me know if this helps.
