Let’s take an in-depth look at using multiple Nest Thermostats in one house.

How Many Nest Thermostats Can You Have in a Home?

According to Google, users can have up to 20 Nest Thermostats and 18 temperature sensors in a home. 

It’s a good idea to install multiple Nest Thermostats if you want to control the heating and air conditioning system from any room in your smart home. 

Advantages of Having Multiple Nest Thermostats

There are a few reasons why homeowners decide to use multiple Nest Thermostats in their homes. The most common include:

  • They have multiple thermostats already. Most modern homes already have multiple thermostats, and Nest can replace each one.
  • They want to adjust the temperature on different floors. Multiple Nest Thermostats allow you to precisely control the temperature on each floor of your home.
  • More zone controls. Multiple Nest Thermostats allow control of different heating and cooling “zones,” or areas where a Nest device is installed.
