The best smart thermostats
Cnet rating: 4.5 stars out of 5
The good: It has a responsive display, a remote sensor and tons of smart integrations, including a built-in Amazon Alexa speaker. The bad: The price is high, particularly if you don’t care about the Alexa speaker or the Ecobee4’s other smart capabilities. The cost: $219 to $234 The bottom line: The best smart thermostat available today.
Nest Learning Thermostat
Cnet rating: 4 stars out of 5
The good: It has a larger display, better resolution and a far-field sensor for viewing time and temperature information from a distance. It works with Google Assistant and Alexa — and Nest finally sells a temperature sensor as an optional accessory. The bad: It isn’t compatible with Apple HomeKit. The cost: $215 to $249 The bottom line: Nest is a solid smart thermostat, but the Ecobee4 offers more home integrations and a better overall value.
Honeywell Lyric T5
Cnet rating: 4 stars out of 5 The good: The geofencing feature worked consistently well, it automated our Home and Away settings every time without complaint, and it sent prompt notifications alerting us to the changes.
The bad: While we like the general design, the font and layout of the touch-screen interface looks dated. We would like to see integrations with Google Home, Samsung SmartThings, Wink and IFTTT. The cost: $140 The bottom line: Honeywell’s Siri-, Alexa-, and geofencing-enabled Lyric T5 is smart, it works well and it offers a better value than other connected thermostats.
Cnet rating: 4 stars out of 5 The good: A responsive touch-screen and integrations with Amazon Alexa, Apple HomeKit, Samsung SmartThings, Wink and IFTTT give the lower-priced Ecobee3 serious appeal.
The bad: “Smart” is a bit of a stretch for the Ecobee3 Lite, since it doesn’t rely on activity-tracking sensors or any other sort of adaptive tech to learn your routine. It is still a lot to spend, especially on a programmable thermostat. The cost: $155 to $170 The bottom line: No other Wi-Fi thermostat available today offers this many smart home partnerships for this low of a price, but you should weigh the importance of the integrations against the price — many seven-day app-enabled programmable thermostats cost just $100.
