Nest thermostat

[LB1949]

I had an electrical outage and now my thermostat is locked.  I don't know the pin number.  How can I get it to unlock?

If your thermostat is still connected to Wi-Fi and you can see it in the Nest app or Home app, you can unlock and reset the PIN using the app:

Lock and unlock your Nest thermostat - Google Nest Help

If you can't control it using the app anymore, you'll need to reset it using a computer.

1. Connect the Nest Thermostat display via USB to a computer.
   
   
2. Verify that the Nest Thermostat mounts (appears as an attached drive icon).

• If the Nest drive will not mount: Restart the thermostat and the computer.
• If the Nest drive still won't mount: Connect another device to the cable to see if it appears as an installed device.
• If it doesn't appear, use a different cable/port/computer.

If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.

Thank you, but I gave up and purchased another thermostat. 

Again thank you for your response.
