Nest foiling my attempts to NOT run AC during peak times

I live in Phoenix, and use APS for power. Finally able to get enough information to truly understand how the rate plan worked, discovered that if I simply DON'T run the AC during peak (4-7) I will literally save hundreds of dollars each month in the summer. I scheduled the NESTs to supercool until 3:45, then start back up at 7:15. Was working great. Today I found both my ACs running at 6 pm...saying they were pre-cooling. The system isn't respecting the schedule, and think it has to run at 6 to get to temp at 7:15.

Anybody know how to defeat this behavior? If they run for just a half hour during peak my bill goes up by over $200 for the month...Agh!

In the home app go to settings -temperature preferences and turn off "early on"

Thank you - that setting is already set to off. If I was a conspiracy theorist, I might think the power company is reaching out to my thermostats to defeat my rate plan optimization. Hmm.

@ssorensonaz

Nope, the Learning Thermostat is just doing what it is designed to do. It learned that it needs to turn the AC on at 6 to get the home cooled to the set temperature by 7:15.

It can take the average AC one hour to cool a room by just one degree Fahrenheit.
