nest learning thermometer won't give an entry

Community Member

Hello, I    have followed other advice on here.  Reset my nest learning thermometer completely (losing all my historical data and my longtime schedule, btw).   I    have uninstalled and reinstalled my app.   Both devices are connected to at home wifi and I    am at home.   The learning thermometer will not give me an entry key.

Also, this never was a problem for me for many years, before Google showed up.

Thank you,

Try these steps:

  1. If the thermostat had a previous owner and hasn’t been reset yet, factory reset the thermostat. If you're not sure, factory reset it anyway.
  2. If you haven’t already, download the Nest app on a phone or tablet.
  3. On the Nest app home screen, tap the Settings cog.
  4. Tap Add product. The app will switch to a camera view to scan the thermostat’s QR code.
  5. On the thermostat, press it to open the quick view menu and tap the Settings cog.
  6. Turn the ring to select Nest app and press to open it.
  7. 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.
  8. Follow the remaining steps in the Nest app.
