Hi, @Kesh1973!

Thank you for reaching out to the community. I apologize that your thermostat is turning on randomly, even with a schedule in place. I understand how important it is to maintain a consistent temperature, especially during colder months. I’m happy to help.

To provide the best assistance, please answer the following questions:

• What type of thermostat do you have? 
• When did the problem start?
• What other strange symptoms have you experienced since the problem started?
• Are there any error messages?
• Would you mind sharing a picture of your wiring configuration?
• When was the last maintenance check for your HVAC system?
• Have there been any recent changes or upgrades to your HVAC system?
• Does the issue happen on heating only, cooling only, or both?
• Is this the first time you're activating heating or cooling since the season changed?

In the meantime, please check the following: 

• Since you have a schedule set up and the heating is turning on randomly, there might be other hidden automations or routines affecting your thermostat. Refer to this article for instructions: How to change your thermostat's temperature schedule.
• Check the Google Home app routines. Ensure no Google Assistant routines are interfering with your thermostat settings. Check out this article: Change Home & Away Routines settings.
• Also, the temperature might be changing on its own because of a Nest Renew subscription or you are enrolled in the Rush Hour program. Please check this information by selecting the links.

Please keep me posted.

Best regards,

Ana
