Not sold on Nest? Here's the best alternatives that you can buy today!

Nest's Learning Thermostat is the go-to solution for many folks looking to add smarts to their heating and cooling systems. That said, it's not for everyone — particularly for those who've gone all-in on HomeKit. That's where the best smart thermostats like the excellent ecobee SmartThermostat come into play. This thermostat may not be as flashy, but it includes almost all smarts, works with HomeKit, and comes with a handy remote sensor. Here's a look at some of the best Nest thermostat alternatives that you can buy today.

Best overall: ecobee SmartThermostat with Voice Control

Not only is it our pick for the best smart thermostat, but the ecobee SmartThermostat also happens to be one of our favorite smart home accessories. This is due in large part to the ever-so-clever remote sensors that independently measure temperature and sense motion. You can use these sensors to give your thermostat a better idea of the temperature in your home (averaged out across the various sensors) as well as whether or not anyone is home.

The ecobee SmartThermostat comes with Amazon's Alexa voice assistant built-in, thanks to embedded microphones that feature far-field voice recognition. That means, on top of working with Apple's HomeKit, remote RoomSensors, and energy-saving benefits, you can use the ecobee SmartThermostat in the same way you'd use an Echo device. Ask Alexa to set a timer, adjust the lighting, remind you to take out the trash, or play some music — you can do it all right from your smart thermostat.

Pros:

  • Easy installation
  • Remote RoomSensor included
  • Supports Alexa, Google Assistant, and HomeKit

Cons:

  • Expensive
  • Requires internet connection for non-HomeKit use
  • Doesn't learn from usage

Best design: Emerson Sensi Touch Wi-Fi Smart Thermostat with Touchscreen Color Display

The Emerson Sensi Touch is a fantastic-looking smart thermostat with a gigantic, color touchscreen display, but it offers more than just good looks. This thermostat has installation-friendly touches such as a backlight, built-in level, and spring-loaded wiring terminals that help to get you up and running in minutes.

Best compatibility: Honeywell Home RCHT8612WF T5 Plus Wi-Fi Touchscreen Smart Thermostat

The Lyric T5+ is an Energy Star certified thermostat that features scheduling controls and location-based temperature settings. That means you'll be able to set a seven-day schedule for your heating and cooling system, and it also lets you control your system with geofences. To add to its smarts, the Lyric T5 also includes a feature called adaptive recovery that keeps track of the time it takes to reach your desired temperature; the more you use it, the better it gets.

The Lyric T5+ is compatible with HomeKit, Alexa, and the Google Assistant, giving you the option to set the temperature using your voice or with a tap. The best part, though, is that it includes a c-wire power adapter even with its low price, which allows for installation in homes that do not have the elusive wire behind their thermostat.

Pros:

  • Adaptive recovery feature
  • Includes c-wire power adapter

Go smart with the best Nest thermostat alternatives

Nest may be the most familiar name for smart heating and air, but it isn't always the best fit. If you are living that sweet HomeKit life, or if you don't want to shell out for the premium design, the best Nest thermostat alternatives are just as good, if not better.

The ecobee SmartThermostat is our go-to pick thanks to its excellent use of wireless RoomSensors, HomeKit compatibility, and easy installation. It may not have all of the smart learning capabilities, but it does come with Alexa baked right-in, and those RoomSensors can offer levels of comforts that Nest cannot match.

If you want to save a little upfront or if you don't like the idea of having an always-on microphone in your thermostat, then the ecobee Lite SmartThermostat is the one for you. With the ecobee Lite, you get access to all of the smarts at an affordable price — and with the ability to add RoomSensors later, you can test drive it before making a full-blown commitment.
