Nest Rush Hour automatically adjusts the current temperature by 3 to 4 degrees based on the current temperature setting. This adjustment should be based, or consider, the current outside temperature.
Case: my thermostat is set at 80 degrees during the day--August in Texas. The auto adjustment set the thermostat to 85 degrees. This is not a safe temperature for elderly or pets.
Recommendation: make adjustments based on outside temp. Of course, Nest and energy companies track usage hourly. There should be data for use in determining the Rush Hour degree adjustment.
