Update, 05/09/2023: We’ve reviewed our recommendations and are confident these are still the best smart thermostats you can buy.

What to Look For in a Smart Thermostat in 2023

Shopping for a smart thermostat is a surprisingly complicated process. Not only do you have dozens of great products to choose from, but you also need to ensure your prospective purchase is compatible with your current smart home setup.

If a smart thermostat is the first part of your connected home, that’s less of a concern. Pick up any of the ones below, and you’re ready to rock. However, if you’ve already put together a smart ecosystem of lights, locks, and appliances, the last thing you want is a smart thermostat that doesn’t play well with your kit.

Thankfully, most smart home systems can effectively incorporate today’s top-selling smart thermostats. Whether you’re an avid Alexa user, love Google Assistant, or are piecing together an interconnected Apple Home, rest assured there’s a product with your name on it.

Beyond zeroing in on your smart home ecosystem, you’ll also have to consider a variety of other factors. Do you want to deal with C-wire installation? Are you open to adding additional sensors to your home? Do you need a smart thermostat with built-in microphones and speakers?

Choosing an expensive product typically means you’ll get all the bells and whistles—but not every home needs every feature. A budget option might be more than enough for what you need, as some even stand toe to toe with premium offerings.

Finding the right smart thermostat is highly dependent on your current setup, but some products stand head-and-shoulders above the competition. Here are the five best smart thermostats currently available based on performance, pricing, and ease of use.

Best Smart Thermostat Overall: ecobee Smart Thermostat Premium

Your smart thermostat is integral to making your house a smart home. That makes choosing one that is compatible with the rest of your smart home kit essential. The ease with which the ecobee Smart Thermostat Premium slots into almost any existing ecosystem is the first of many reasons it tops this list.

The thermostat has Alexa built into the device, so you can start using voice commands as soon as it is installed. It is also compatible with Google Assistant, SmartThings, IFTTT, and Apple HomeKit. If you have an Apple HomePod speaker, you can also link that up and use Siri commands.

The ecobee eco+ software, makes recommendations based on your schedule, household humidity, and on/off-peak pricing based on AI analyses. What it doesn’t do is try to impose those recommendations on you—automatic overriding of your settings is a sometimes frustrating feature of other smart thermostats that isn’t here.

There is a sensor for monitoring air quality, and the device checks the weather in real-time to give better temperature recommendations. How well the air-quality sensor works depends on where you position the thermostat. Indeed, it might have been better to have it on the much more portable SmartSensor bundled with it.

The ecobee Smart Thermostat Premium is not cheap, although the price is in line with similar devices. For your $250, you get a stylish, feature-rich smart thermostat made from quality materials. The large, bright display is a joy to use, and the clever software will help you save money on your energy bills.

Best Budget Smart Thermostat: Amazon Smart Thermostat

Don’t let its rock-bottom price tag fool you—the Amazon Smart Thermostat can hang with the best in the business. Although the thermostat is a newcomer to the smart home arena, Amazon leveraged over 130 years of experience by building it on the Honeywell Home platform.

The Amazon Smart Thermostat is more than just reliable and affordable, as you’ll find plenty of functionality packed into the handsome device. The product is officially Energy Star certified, meaning you can expect to save an average of $50 a year on your energy bills. Plus, its Alexa compatibility makes it easy to adjust the temperature when away from home.

Alexa Hunches can automatically change the temperature for you based on your preferences. Whether you’re home, away at work, or about to fall asleep, Alexa can tweak your home’s temperature without much input on your end.

The biggest drawback to Amazon Smart Thermostat is the required C-wire or power adapter, making the installation process more challenging. However, if you already have a C-wire installed, getting Amazon Smart Thermostat up and running is as simple as connecting a few cords, which takes a lot of the installation work out of it.

Anyone in the market for a capable smart thermostat that doesn’t break the bank could do a lot worse than Amazon’s latest invention.

Best Smart Thermostat for Apple Homekit: ecobee3 lite Smart Thermostat

Apple Homekit makes it easy to manage all your smart appliances with a single app. However, sometimes it can be difficult finding products that work seamlessly with Apple’s smart home ecosystem. Thankfully, the ecobee3 lite SmartThermostat should be a perfect fit for all your smart home needs.

Available for $170, the ecobee’s smart thermostat is surprisingly capable for a sub-$200 smart thermostat. Apple enthusiasts will love its built-in Apple Homekit support, and they’ll be even more pleased that it can save up to 23% annually on your heating and cooling bills.

Some of its most advanced features, such as managing hot and cold spots throughout your home, require a subscription to ecobee’s Smart Security plan and an additional SmartSensor room sensor. But beyond the big of extra cost, there’s not much to really complain about with the lite SmartThermostat.

Whether you’re just starting your Apple Homekit adventure or if a smart thermostat is the last item on your list, the ecobee3 lite is bound to be a perfect, money-saving addition to your home.

Best Smart Thermostat for Alexa: Amazon Smart Thermostat

The Amazon Smart Thermostat emerges once again, this time as the best pick for fans of Alexa. While it lacks built-in voice control or smart speakers, the smart appliance can easily connect to any other Alexa-enabled device in your home. Specifically, Echo Dot or Echo Show users will find Amazon’s Smart Thermostat perfect for their needs.

Although it requires the installation of a C-wire, there’s a good chance your current thermostat is already equipped with one.

And if you need to install a C-wire, the Amazon Smart Thermostat helps with guided instructions via the Alexa app on Android or iPhone.

Not only will Amazon’s new smart thermostat save you at least $50 a year on energy bills, but it also carries a paltry $60 price tag. That’s less than half the price of most competitors—yet it still manages to pull together an impressive list of features.

As long as you can look past its lack of built-in microphones and speakers, the Amazon Smart Thermostat is the perfect fit for your Alexa-powered home.
