How does the Nest Thermostat work if I have multiple Nest Learning Thermostats in the same home?
If you have more than one Nest Learning Thermostat in your home, they work together to keep you comfortable and save energy.
If you have multiple thermostats in your home, you can replace any or all of them with a Nest Learning Thermostat. While Nest Thermostats work just fine with regular thermostats, your home benefits from additional features when every thermostat is a Nest Thermostat.
With more than one Nest Thermostat, you get the benefit of Nest Sense from each thermostat. Every Nest Thermostat contributes information to coordinate Auto-Away in your home. Only when every Nest Thermostat senses that you're away will the thermostats in your home go into Auto-Away. When one Nest Thermostat senses that you've returned, every thermostat will return to its usual schedule.
Note: Every Nest Thermostat in your home needs to be associated with the same location in the Nest app or on the Nest website for coordinated Auto-Away to work.
While Nest Thermostats will share what they sense in order to coordinate Auto-Away, each thermostat will learn a separate schedule (you can control thermostats separately on your Nest Account too). Since each Nest Thermostat learns a separate schedule, you can use your thermostats with zoned systems to create different temperatures in different parts of the house. So you can teach your thermostat in the kitchen to warm up in time for breakfast, just as the thermostat in the bedroom turns down for the day.
It's especially important to teach each Nest Thermostat to save: when the family is sleeping upstairs at night, the thermostats in the living room and the basement don't need to be set to comfort temperatures--so teach the downstairs Nest Thermostat to turn the heat down at nighttime.
