Hi both,
Confirming what I suspect you've read elsewhere but I'll include the advice in full the benefit of others that may land on this topic.
If you can't control the thermostat using the app anymore and/or it's disconnected/cannot be reconnected to the Wi-Fi network it was connected to, 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, you should see technicalinfo.PLIST file. As you mentioned already getting this far, I've asked a community specialist to assist with next steps, as these can't be shared publicly in the community. Alternatively, you're welcome to contact Google Nest support directly using the steps below and they can also support.
- Go to Contact Us - Google Nest Help
- Select an appropriate product or category, type a brief description of the issue, then click Next.
- Click Other, then click Next step.
- In the Resources section, click Next step.
- Choose to get a phone call, call or chat with the team, depending on availability in your country.
