Power and wifi outage

[Ctorlish]

We have a power and Wi-Fi outage. Have generator power but thermostats are saying offline with y1 error message e80. This happens whenever we lose power how do you recover

Hey Ctorlish,

Thanks for reaching out. If you recently experienced a brownout or blackout, you can try turning off and on your HVAC system to refresh the connection. 

You can use this link on how to Troubleshoot Nest thermostat help codes.

Thanks,
