Hi @KG1277,
Thank you for posting in the community. I understand you'd like to know about setting up a minimum temperature setting and a 'lock' feature for your Nest Thermostat. That sounds like a great option to avoid getting your place too cold and to prevent unwanted people from accessing the thermostat's settings. I'm happy to help.
The closest feature for your request that we have available is the Hold a Temperature feature. This option works with the Nest Thermostat (2020) or the Nest Learning Thermostat (4th gen). Earlier versions of the Nest Learning Thermostat and the Nest Thermostat E don't have a dedicated 'hold' function, but you can still manually change the temperature, and the thermostat will learn from your adjustments.
To provide you with the most accurate assistance, please answer the following questions:
As for the lock feature, there's a way to lock and unlock your Nest Thermostat. You can lock your thermostat in the Settings menu on the device itself, or with the Home or Nest app. To unlock it, you'll need to enter the four-digit PIN code on the thermostat or use the app. When a Nest thermostat is locked, it will still heat or cool to any temperatures in your schedule, even if they are outside of the locked temperature range. It will also follow your Eco Temperatures
. You can learn more by visiting the article Lock and unlock your Nest thermostat.
Please keep me posted.
Best regards,
Anders
