nest thermostat

[Verity]

I have read all the reconnection instructions time and again.  My thermostat is locked, I have lost the pin, I can find the thermostat on the app.  I can plug it in via USB to my computer but the I understand I need to contact Nest for a reset.  Where is the link, or how do I do that?  I am 83 and sick of going round and round in circles.

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:

Only if you can't control it using the app anymore do you need reset it using a computer. Those steps are below.

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.
