As our society moves towards energy-efficient technology, we are always looking for ways to improve energy efficiency and sustainability. The Nest thermostat, an Energy Star-certified device, is designed to reduce heating and cooling costs while saving energy. With this in mind, I wanted to research if it’s possible to have two Nest thermostats in one house to maximize efficiency.

If you decide to use the Nest Thermostat in your house, you are not limited to one device. Multiple Google Nest thermostats in the same home will successfully work together to maintain consistent levels of temperature monitoring and energy efficiency.

In this article, we’ll take an in-depth look at using multiple Nest thermostats in one house, including some tips for customizing your setup.

How Many Nest Devices Can You Have in a Home?

Given that you can have multiple Nest Thermostats in one house, you may be wondering how many Nest devices are supported in a single residence. According to Google, users can have up to 20 Nest Thermostats and 18 temperature sensors (6 per thermostat) in a home.

It’s highly unlikely that you’ll need this many Nest devices, but it’s good to know that if you ever wanted to be able to control the temperature of every single room in your home, the Nest has you covered!

A Quick Look at Nest Thermostats

The Nest Thermostat is a smart home “learning” device designed to provide advanced levels of customizability with your home’s temperature and environmental conditions. Additionally, the thermostat has adaptive learning with behavior patterns and desired temperatures for specific scenarios (certain days or times of the week, etc.).

The device is also easy to install and works with most existing HVAC (heating, ventilation, and air condition) systems, requiring little setup. Nest Thermostats also operate with energy-saving settings, so you aren’t overusing your system.

The table below illustrates some of the thermostat’s core features and specifications to give a better idea of how the system operates:

Display480×480 Resolution 24-bit color LCD
ConnectivityWi-Fi Connection 802.11b at 2.4GHz or 5 GHz Bluetooth Low Energy (BLE)
BatteryBuilt-in Rechargeable Lithium-ion Battery
Power Consumption< 1 kWH Per Month

Nest Thermostats will work with most 24V systems and all common fuel types (gas, oil, and electricity).

Now that we have a better understanding of what the Nest Thermostat has to offer, let’s discuss the advantages of using multiple devices in one house and some tips for adding a second thermostat.

Advantages of Having Multiple Nest Devices

There are a few reasons why homeowners may decide to use multiple Nest Thermostats:

  • Multiple Existing Thermostats: It is not uncommon for many modern homes to already have multiple thermostats on their property, and Nest can be used to replace any or all existing devices.
  • Multi-Story Homes: If you have a multiple-story house, having the ability to control the temperature independently on each floor can significantly reduce energy costs.
  • ·         Zone Control: With multiple Nest Thermostats in your house, you can control different “zones” (or areas where the Nest device is installed). Have a family member who likes their room cold but the living room warm? Since Nest controls heating and cooling independently, you can customize the temperatures of different “zones” in the same house.

How to Add a Second Nest to Your Home

If you’ve decided that you want to add another Nest Thermostat to your house, fortunately, the process is intuitive and straightforward. You can add Nest devices using the associated Nest app.

Even if you’re not the homeowner, friends and family can be given “shared access” to customize the devices as well.

Here’s a quick guide to get you started adding a second Nest Thermostat to your home:

  1. Open the Nest app (Android or iOS).
  2. Press the menu button in the top left corner of the main screen.
  3. Next, select the home or location you are adding the device to.
  4. Press the “Settings” icon in the top right corner.
  5. Select the Add Product “Plus” button.

Once you’ve added the associated thermostat, the app will walk you through the initial setup steps. Additionally, if you are unfamiliar with the initial configuration (or are installing your first Nest Thermostat), Google offers a helpful guide on their support page with diagrams to get you started.

Final Thoughts

For many homeowners, saving money and energy with frequently used devices is often at the forefront of their minds. We try to find the balance between the amount of features technology can provide while still being mindful of its impact on our environment.

Google’s Nest Thermostat is one such product that successfully blends both functionality and energy efficiency. Not only can homeowners use multiple Nest Thermostats in their homes, but it can be used to save more money in the long run.
