Problem: The Google Nest Learning Thermostat continues to randomly alter the heating setpoint overnight, typically (but not exclusively) between Midnight (0000 hrs) to 6am (0600 hrs). The number of times when temperature setpoints are altered can vary from day to day. The problem was so pervasive that the decision was reached to do a Factory Restart. This erased all history, auto-schedule points as well as forcing the thermostat to be reinstalled. To further ensure that all operational anomalies were removed, the thermostat was removed from the Nest App. The software installation process (with selections shown below) was followed meticulously after the thermostat rebooted. As an initial test, the thermostat was set manually for one time and then again in the evening. No other changes were made during the day or overnight. Still the Energy History showed two Temperature Setpoint Changes made at approximately 3am when we were asleep. Therefore, with every “Learning Function” and “Home/Away Assist” turned OFF, the thermostat still indicates multiple changes in the temperature setpoint. What else can be done to eliminate this problem?
