This morning I had a thermostat “flip” out of ECO to operating mode (unexpectedly)
There are multiple thermostats in the location
Structure is set away. All thermostats were away, then one flipped to running
Nest Home / Away Assist is on, but the devices and phones are set to NO for adjusting. Home away assist is set for ECO when away, and on when home.
Any thoughts on why a thermostat is randomly switching out of ECO, in a empty home. (No one has been there for weeks).
