Using multiple Nest thermostats in the same home

If you have more than one Google Nest thermostat in your home, they’ll work together to try to keep you comfortable and help save energy.

If you have multiple thermostats in your home, you can replace any or all of them with a Nest thermostat. You won’t need to replace all of your current thermostats, they’ll keep controlling your system just like they always have. You shouldn’t need to change any settings.

If you’re only going to replace one of your current thermostats with a Nest thermostat, it's recommended that you replace the one in your main living area. That way it can better tell when you’re home, learn what temperatures you prefer, and automatically help you save energy.

How Nest thermostats learn

Your Nest thermostats will learn separate schedules

Nest thermostats in the same home don’t share temperature schedules. Each Nest thermostat learns a separate schedule for the zone that it controls. So you can teach your thermostat downstairs to warm up the kitchen in time for breakfast, while the thermostat upstairs turns down for the day.

Eco Temperatures can help save energy

Your phone's location and Nest product sensor data are used to tell when your home is empty or occupied. So all of the Nest thermostats in your home can switch to Eco Temperatures when you’re away, and back to your regular temperature schedule when you return.

You can also set Eco Temperatures manually on any of your Nest thermostats to save energy in one part of your home. Your other Nest thermostats will continue to run their normal temperature schedule to keep you comfortable.
