Temperature autochanging

I've sorted through most of the posts where the Nest thermostat version 3 is not following the schedule. I can't seem to stop it from cooling at 72 degrees, even though the schedule is a simple Cool at 78 degrees, every day.

• Nest has been following the schedule for years now, but within the last week it flat ignores the schedule at night
• No events show an override to temperature, but history does show it's kicking off the lower temperature in the middle of the night.
• ALL options such as learning, ECO, Home and Away, etc. have been disabled.
  I've deleted the simple one temperature per day schedule and replaced it with a similar one.

I've read the post that suggests I change the mode from Cool - to Heat and Cool...but that makes no sense. The thermostat has been following the schedule forever. Heat pump is 5 years old, cools well when needed.

What has changed that is telling nest to initiate a unrequested cooling temperature of 72 degrees in the middle of the night, and what do I do the get Nest to follow the program?

What has changed is Nest Renew has recently been released and it is changing temps/turning AC on/off based on when NEST determines your local power mix is cleaner/dirtier.

I had similar experience/history as you, but recently I turned off all scheduling through NEST and went to Google Home Automations to manage my AC based on my local on/off peak rates (higher/lower).

From another response/thread, but this is the third night I have caught Nest turning off my AC at night even though I have all the functions turned off, as you noted.

"The new Nest "Peak Time" function activated twice last night and turned off my pre-cooling, which is quite annoying.  It shows up in the activity log for GHA if one is not watching NEST 24/7 while sleeping to see "Peak Time until ##.## [time]""

Here are 2 images, one from Nest activating ‘Peak Time’ and another from Google Home Assistant’s activity log.

Hi everyone,

@billnye427, thanks for reaching out here in the Community. To confirm, do you have a Nest Renew subscription? Do you have a routine set up from your Google Home app? If so, try checking for Nest Thermostat actions and remove or edit it when needed. Hit this link for more information.

I appreciate your response, HansWT.

Regards,

Emerson

Hey billnye427,
