Nest Thermostat - Forgot Pin

[Emikey1]

Device is offline & requesting PIN. 

PIN forgotten. It’s in a rented property which complicates the trouble shooting.

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.

We have order a cable and will follow steps outlined above and then get back in touch. Many thanks. Please bear in mind it’s at a rented property so I will need to liaise with the tenants to follow specific instructions.
