If you’re a Nest thermostat owner, you may want to know how to lock your Nest thermostat to prevent others from changing the temperature or accessing your settings.
Locking your Nest thermostat can be helpful if you have kids who like to play with the temperature or if you’re renting out your property.
Fortunately, locking your Nest thermostat is a simple process that can be done using the Nest app or directly on the thermostat.
To lock your Nest thermostat using the app, you’ll need to enter a four-digit PIN code. Once your thermostat is locked, it will still heat or cool to any temperature within the range you set.
You can also unlock your thermostat using the app or by entering the PIN code on the thermostat.
If you have the latest model of Nest thermostat from 2020, unfortunately, it doesn’t have the PIN lock/unlock feature, and you won’t be able to control it with the Google Nest app as it can only be controlled in the Google Home app.
If you prefer to lock your Nest thermostat directly on the device, you can do so by tapping on the gear icon at the top right corner of the screen, scrolling down, and selecting “Lock.” Then, type in a four-digit PIN code to lock your thermostat.
You can also set the locked range, which means that while locked, the temperature can only be adjusted within this range. Once you’ve set everything up, tap on the “Lock” button to save your settings.
