Nest thermostat shows N5 and cannot connect to the Nest app via Bluetooth during setup

Note: N5 occurs during initial setup or re-pairing.

• Move closer: Stand within a few feet of the Nest thermostat with your phone.
• Enable Bluetooth: Ensure Bluetooth is turned on in your phone's settings and that the Google Home or Nest app has Bluetooth permissions.
• Restart both devices: Reboot your phone and restart the Nest by holding the ring for 10 seconds.
• Clear app cache: On your phone, clear the cache/data for the Google Home/Nest app and try setup again.

If N5 continues, try using a different phone or tablet for setup.
