Smart thermostats do so much more than let you change the temperature through your smartphone. Different models can detect when you’re home, target temperatures to the room you’re in, adjust to your schedule and more. Here are three of our favorites, based on professional reviews and each thermostat’s features.
Learns from You: The Nest, $249
The Nest Learning Thermostat (3rd Generation)‘s biggest draw is its ability to learn your schedule. It will adjust over time so your house is at your preferred temperature throughout the day. You can buy optional Nest sensors to place in different rooms so you can target the temperature to the sensor you prioritize at different times, although they lack motion sensors to automatically tell where you are. The Nest is consistently one of the top picks on review sites and gets higher than four stars in customer reviews across multiple retailers. Check out these other smart home devices you’ll love.
Built-in Smart Speaker: ecobee, $249
The ecobee 4 Smart Thermostat includes a built-in, fully-functioning Alexa. The thermostat comes with a temperature sensor with motion detector so the thermostat can target occupied rooms; additional sensors cost $79 per two-pack. A combination of geofencing (in other words, where your phone is) and the motion sensors let the thermostat know whether you’re home. It won’t learn your schedule like the Nest, but you can program home, away and sleep events. This thermostat is consistently a top pick among professional reviewers.

Budget Pick: Honeywell, $199
The Honeywell Home T9 Smart Thermostat with Sensor comes with one motion-sensing temperature sensor so you can target the temperature to occupied rooms; you can buy additional sensors for $40, or $75 for a two-pack. It uses geofencing, but only to tell when you’re not home, and you can set a schedule, but this thermostat won’t learn your schedule like the Nest. This model, and the older Honeywell Lyric T5, are frequent budget picks on review sites.
Keep in Mind
Before you pick a smart thermostat, evaluate your home’s setup to make sure a specific thermostat will work for you. It may be helpful to know top problems with smart home technology.
Mind the C-wire: Most smart thermostats require a C-wire, or common wire, connected to the HVAC system to provide a return path for power to the thermostat. An existing C-wire isn’t always in the wall, especially in older homes. You can install a C-wire or adapt your setup if you want to install a thermostat that requires a C-wire.
Will it work with your HVAC?: Check the types of heating and cooling systems a thermostat is compatible with before you buy. If you have dual zones in your home, or separate heating and cooling systems, see whether you’ll need multiple thermostats.
Other integrations: If you already use smart home devices, see whether your chosen thermostat integrates with your ecosystem, or if it will require additional setup.
