https://www.googlenestcommunity.com/t5/Nest-Thermostats/thermostat-passcode/m-p/5392#M1103 <P>Lost wifi connection and then my thermostat froze. I read about removing it and re-adding it. I went to re add it and it asked for my passcode on the thermostat. I can't remember the passcode on the thermostat. I can't re add it to the app without the passcode to unlock the thermostat. I have access to my app ect. just not the passcode on the thermostat itself. The thermostat is no longer a listed device to access its settings. Please help&nbsp;</P> Sat, 04 Sep 2021 02:30:54 GMT bernadette 2021-09-04T02:30:54Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/thermostat-passcode/m-p/5392#M1103 <P>Lost wifi connection and then my thermostat froze.
