I noticed my display was strange… I was only seeing half of the number zero, and 8 was just a block of static. Tried re powering, that didn’t help. Then went into settings, and tried “resetting”. That seemed to brick the unit. The display is stuck on WYZE… repowering doesn’t work… Sometimes if I hold the button down, I will get the “reset” no/yes screen. No takes you back to WYZE, Yes tries to reset, and you guessed it. I get WYZE.
That is the thermostat’s pairing screen. The reset function will factory reset the thermostat and disconnect it from the app. Have you tried adding it back to the Wyze app?
