Having the same issue here with the Nest Thermostat E! Tried everything!

I'm in the same boat. Connect properly first time and deleted thermostat from home due to moving. Now sensor gives error above.

I sat on a chat with nest for 2 hours and it didn’t do anything. I deleted the thermostat from the nest app; reset the nest thermostat to factory default; I also removed the battery from the sensor overnight and then tried it 24 hours later and it’s been up and running since.
