Hello @Lady5
Thanks for reaching out to our Nest Community. I apologize for all the inconvenience of controlling your Nest Thermostat. Don't worry; I'm happy to help you with this situation.
Follow these steps to unlock your Nest thermostat with the Nest app:
- Tap the Nest thermostat that you'd like to unlock.
- Tap the Settings Nest settings at the top-right corner.
- Scroll to the bottom of the menu and tap Unlock.
If you can't control it using the app anymore, you'll need to reset it using a computer.
- Connect the Nest Thermostat display via USB to a computer.
- 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 help you with next steps, as these can't be shared publicly in the community.
Feel free to keep us posting, we're here to find a solution for you.
Best regards,
Douglas.
