I’m not using any third-party integrations, I added this through SmartThings using whatever native handlers it has.
This was working happily for a few days, but suddenly (today) SmartThings is showing the inside temp as 106°. The thermostat display shows 70°. SmartThings says it is “connected” and it does allow me to change setpoints successfully. But as long as SmartThings shows it at 106°, my heat won’t work.
