Can't connect Nest thermostat to Home app

For the last week my Nest thermostat has been working intermittently & showing a low battery (3rd Gen Nest hard wired).  All other Nest devices working properly.  Reset router anyway.  Selected device reset on thermostat & removed in the Home app.  Started setting up thermostat again without scanning QR code, entered 6 digit code in home app, went to next screen saying to select last 4 digits of S/N in Home app, but screen was blank.  Then tried setting up scanning the QR code & the received message "Unable to start device pairing.  Configuration not available".  This thermostat has been working since 2018.  I have not changed anything.  Can't get A/C to work & weather is very Hot! Please respond.

Although the thermostat will appear in the Home app, that's only after setup. For setup of that thermostat model, you need to use the Nest app, not the Home app.

  1. On the Nest app home screen, tap the Settings cog.
  2. Tap Add product. The app will switch to a camera view to scan the thermostat’s QR code.
  3. On the thermostat, press it to open the quick view menu and tap the Settings cog.
  4. Turn the ring to select Nest app and press to open it.
  5. Select QR code. Your thermostat will show you a unique QR code to scan with the app. If it doesn't, tap Continue without scanning in the app and select Get entry key on your thermostat instead.
  6. Follow the remaining steps in the Nest app.

If those steps don't work, try a factory reset of the thermostat and retry the setup steps.
