Ex was owner of device & he moved

[SamOle]

My ex was the account holder for the Nest and he has since moved out. We are no contact and I don’t know how to transfer to my name to control the thermostat.

Hi @SamOle 

Not to worry, here's what you need to do next.

First check which model of thermostat you have:
How to tell which Nest thermostat you have - Google Nest Help

Important: In case you need to reset the thermostat, I would recommend you write down the wiring information so you can easily enter your thermostat's wiring if needed. On your thermostat, go to Settings > Equipment. You might want to do this for other settings, such as system heating type, and safety temperature as well.

Nest Thermostat (2020), Nest Learning Thermostat (4th gen)

1. If the thermostat hasn’t been reset by the previous owner, on the thermostat, go to Settings > Account > Disconnect.
2. Follow the setup steps: Get started with your Nest Thermostat - Google Nest Help

Setup these models using the Google Home app. The QR code and setup key are physically printed on the back of the thermostat for Nest Thermostat (2020) and will be displayed on screen for Nest Learning Thermostat (4th gen).

Nest Thermostat E, Nest Learning Thermostat (3rd gen)

1. If the thermostat hasn’t been reset by the previous owner, on the thermostat, go to Settings > Reset > Account connection. If you don't see this option, you'll need to select All settings.
2. Follow the setup steps: Add your Nest thermostat to the Nest app - Google Nest Help

Setup these models using the Nest app. The QR code and setup key are in the settings on the thermostat itself and are not printed on the device.
