Thermostats have come a long way since the days of manually adjusting a little dial when the room felt too warm or too cold. Now, smart thermostats create a digital experience that allows you to control so much more than the temperature of a room to the precise degree. They are also equipped with other convenient functions, like touchscreens, WiFi capability, and multiple room control.

One of the biggest benefits of setting up a smart thermostat, however, is energy reduction. Many smart thermostats operate on their own by adapting to your schedule and routines and adjusting the temperature accordingly. That means your home won't be cooling or heating (and racking up a high energy bill) when it's not being used.

What to Look for in a Smart Thermostat

Before buying a smart thermostat, you should double-check that it is compatible with your heating, ventilation, and air conditioning (HVAC) system. Not all thermostats are capable of controlling the full system, so it's a good idea to take note of your system and cross-reference that with the thermostat you're interested in purchasing.

A few things to keep in mind when shopping for the best smart thermostat for your home are its smart features, overall style, and integrations with your current smart home setup, which could be Google Home, Alexa, or Apple HomeKit. You should also keep in mind how often you'll be away from the house and consider the app's usability so you can easily adjust the temperature from wherever you are.

The best overall smart thermostat marries high-quality features with an approachable price tag. The Google Nest Thermostat E is a lighter version of the original Google Nest Learning Thermostat, but there are actually very few differences between the two aside from price and appearance. This one comes equipped with voice control (which works with Google Assistant and Alexa), can be controlled from anywhere using the Nest app, and saves energy by powering off when not in use. Additionally, the Google Nest Thermostat E is made with plastic instead of glass and steel. But customers note that the white exterior makes it more minimal in design and allows it to blend in seamlessly with its surroundings. "Easy to install, program, and use," wrote a reviewer.

Best Rated: Google Nest Learning 3rd Generation Thermostat

Since its inception in 2011, the Google Nest Learning Thermostat has consistently been given high ratings and glowing reviews by customers on Amazon, and it's easy to see why. This smart thermostat is the complete package, combining style and function into one sleek and easy-to-use tool. In addition to its bright high-res color display—that shows the time and weather in addition to the room temperature—the Nest is programmable and adapts to your schedule in order to save energy and money. Customers praise the thermostat for its cool design and ease of use. "I can easily pull everything up on my phone, and often do, to change the temperature, whether I am on the couch or in bed already. It is perfect," said one reviewer.

Best Affordable: Honeywell Home Wi-Fi Programmable Thermostat

For under $100, this Honeywell smart thermostat is the most affordable one you will find. But thousands of positive online reviews mean this budget-friendly smart thermostat is still highly rated. What it lacks in aesthetically pleasing design, it makes up for in function and smart capabilities, including WiFi integration, voice control, and smart alerts that notify you about temperature changes and the air filter status. It also allows you to set up a seven-day schedule with up to four different programs per day, which provides the flexibility to create an optimal environment depending on time of day or day of the week. A customer wrote, "I have purchased five of this exact model off of Amazon and absolutely cannot be more pleased with the product, the price, and how it functions."

Best for Alexa: Ecobee Smart Thermostat with Voice Control

Similar in design to the Nest, Ecobee's top-rated smart thermostat has a sleek exterior with an easy-to-read touch display and a glass finish. It even comes with a smart sensor.

Easily use your voice to control the temperature, or take advantage of Alexa's other capabilities, like getting updates on the weather or playing music. "The integrated Alexa voice service makes this already great smart thermostat even smarter," said one customer. Another reviewer praised the Alexa integration: "Alexa works perfectly on the Ecobee and, honestly, even better than some of the other devices I own that offer Alexa control."
