Hello @Clemmer1967
Welcome to our Nest Community. We're happy to see you here. I will help you with your Nest Thermostat.
I completely understand your situation. If your Nest App shows the Nest Thermostat is already connected, you can try these steps:
Reset Account Connection: On your Thermostat, go to Settings > Reset > Account Connection.
After you reset the account connection, you'll still find your Thermostat in the app. However, your Thermostat will be listed as "offline," and you'll no longer be able to control it with the app. To remove it from your account and app, you'll need to go to your thermostat's settings.
Get the QR code: On your Thermostat go to Settings > Nest App > Select QR code.
Follow the normal setup process, and you will control your Thermostat and throw your cellphone again.
If the first steps don't change anything, try a factory reset. Settings > Reset > All Settings and follow the setup process.
Feel free to keep us posting. I'm happy to help you with your situation.
Best regards,
Douglas.
