Nest thermostat setup showing wrong serial number

[Ramzzm]

I bought a nest thermostat about a year ago and successfully set it up. This week I was painting my house and removed it. On trying to plug it back in, I keep getting no power issues. I factory reset it and now keep getting “Continue Setup in app”. 

While setting up, it asks me to pick the last 4 characters of the device’s serial number. Unfortunately it shows the wrong serial number. 

I tried the home app on iOS, and also on my wife’s Android device. It’s getting really cold and it’s very frustrating that a simple setup is making me lose my mind.

Hi Ramzzm,

Thanks for reaching out to the community. I'm sorry to hear that you are having problems setting up the thermostat in your app and are showing you the wrong serial number. I'm happy to assist you right now.

• What type of Nest thermostat do you have?
• Where was the thermostat installed before, in the Google Home App or the Nest App?
• When you had power issues, did you have an error code in the thermostat screen?

Any additional details you can provide will be helpful.

Regards,

Gabriela
