I have a Gen 3 thermostat with checked - Model Display-3.7 being reposted from the nest app.
When i try to pair a Gen 1 temp sensor in the Nest app it says
this nest temperature sensor won't work with your thermostat
It then lists the ones it is compatible with.
I have tryed to restarting the thermostate and taking the battery out of the temp seneor for 10 mins and retrying.
My network is fine and works with everything else and bluetooth was turned on, on the phone.
The senero was a few CM's away from the theromostate and could hardly get any closer.
