6 Best Smart Thermostats in 2024

In our tests, this advanced smart thermostat from Ecobee was a cinch to install using the mobile app’s illustrated guide. It has a sleek design and it's loaded with features, including geofencing technology that detects when you’re home and adjusts the temperature accordingly. There's also a built-in air quality monitor, voice control and music streaming through its built-in speaker via Bluetooth or Spotify. It comes with one wireless temperature sensor that independently measures the climate of any room you place it in.

We found the device’s touchscreen display and the Ecobee app easy to use. The system did a fine job of learning our tester’s habits and creating a customized temperature schedule for his family’s needs. It’s on the pricier side, but you get a lot for your buck.

Wyze’s reputation for value-driven smart devices continues with its smart thermostat. In our hands-on review, the device didn’t win any beauty awards, but if you’re looking for a no-nonsense thermostat that’s relatively easy to install with intuitive controls, Wyze is the way to go.

Even at its bargain price, the thermostat has several features our engineers like, including voice control, geofencing and sharing access if you want to give temperature control to long-term visitors.

Nest is the leading name among smart thermostats, and it’s now part of the Google smart home ecosystem. The third-generation version was one of the favorites from our tests due to its capability to learn your habits over time.

Another standout feature is its ability to alert you if your HVAC is acting up or if there is a danger of your pipes bursting due to freezing temperatures. Similar to the Ecobee, the Nest can track energy usage and provide energy-saving tips. It's not cheap, however one tester found that the Nest learned when they came home and was able to adjust the temperature accordingly, which ended up saving them money on their heating bill.

The display screen offers helpful information like the time, temperature and weather. We also love that it comes in a variety of designs and finishes. One tester did have issues with integrating the wiring of the device into their current heating and cooling system and had to call in professional help. Be sure to ensure the installation compatibility matches your current setup (more on that below).

The Bosch smart thermostat has many of the features we appreciate, including Alexa integration. It's also popular with HVAC professionals because it’s such a robust device, controlling not just the temperature, but other air conditioning equipment that may be installed in the home, such as ventilation systems or whole-house dehumidifiers.

Its large touchscreen is great for viewing info like the time, temperature and local weather. While this thermostat is compatible with most HVAC systems including heat pumps and conventional systems, it does require a Wi-Fi connection and a C-wire, which provides continuous power to the digital display. If your home is not already equipped with a C-wire, one would need to be professionally installed.

Smart thermostats used to be hard to come by for homes with baseboard electric heating, which is why our experts like the Mysa Smart Thermostat for electric baseboard heaters. (There’s also a version specifically designed for electric in-floor heating.) We found the app experience to be similar to what you’ll find with other smart devices, and one of our testers loved that she could plan ahead for her day and come home to a comfortable temperature.

We liked its ability to remotely control the system, chart energy consumption and set up geofencing options. While the Mysa doesn't control cooling equipment, it plays nicely with smart home assistants including Apple HomeKit, Amazon Alexa and Google Assistant.

The Nest E smart thermostat has most of the same features as its more expensive counterpart, just in a more affordable yet sleek design. For example, its frosted display only tells you the temperature, whereas the mirrored glass display on the premium Nest also shows you the time and weather.

But the Nest E is still loaded with helpful attributes like geofencing, alerts and energy tracking. Consumer feedback on the frosted display was split — some found it aesthetically appealing, and others found it difficult to read. Also important to note: If you live in an older home that doesn’t have a C-wire, you might have to bring in a professional to install one.
