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