Once you’ve adjusted the temperature just by talking to your Amazon Echo, it’s hard to go back to the barbaric old ways of using an app or a dial.
Look for the words “Works With Alexa” to find smart thermostats that you can control through a separate Alexa-enabled device, such as an Amazon Echo, Echo Dot, on the same WiFi network.
“Works with Alexa” smart thermostats are easy to find. Here are some of our favorites:
Look for “Alexa-enabled” to find smart-thermostats that have Alexa built right into their hardware. As of this writing (September 2017) the ecobee4 is the only major thermostat with Alexa built right into the hardware.
How Alexa works with your thermostat
Example Alexa smart thermostat commands
- “Alexa, set the bedroom temperature to 65 degrees”
- “Alexa, raise the temperature by 4 degrees.”
- “Alexa, set the ‘thermostat name’ to 75 degrees”
Manufacturer-specific Alexa commands:
A closer look at some of our top choices
Rather than give orders to an Alexa-enabled device elsewhere in your home, the ecobee4 has Alexa built right in. This means you can speak directly to your ecobee4 thermostat, which would have made you look crazy 20 years ago but totally futuristic and modern today. It even has its own little blue light across the top to indicate that Alexa is speaking or thinking.
Aside from Alexa integration, the ecobee4 is virtually identical to the ecobee3, which has enjoyed a multi-year run as our overall top smart thermostat pick.
Ecobee3 (Works with Alexa)
Long our overall top-pick, the ecobee3 smart thermostat uses individual “room sensors” to detect motion and temperature on a room-by-room basis, helping put an end to chronically under-heated or under-cooled rooms. With Alexa integration, all you have to say is “Alexa, set the temperature to 72” to an Alexa-enabled device (such as an Echo or a Dot) and ecobee3 can take it from there.
Emerson Sensi (Works with Alexa)
The Emerson Sensi is far easier on the budget than most smart thermostats, but not much lighter on features. It even runs without a C-wire in many systems, making it a popular alternative for homes that lack the wiring to run some of the fancier touch-screen thermostats.
With added Alexa support, the Sensi continues to keep up with its pricier competition .
Nest Learning Thermostat (Works with Alexa)
It’s the granddaddy of the smart thermostat family with its iconic click-wheel design and bright circular interface. Nest Learning Thermostat’s claim to fame has always been its “hands off” ease of use (you don’t even have to program the thing, it just tries to “learn” your schedule on its own), and that ease of use just got even easier with Alexa integration.
Honeywell RTH9580WF Smart Touchscreen Thermostat (Works with Alexa)
Honeywell’s answer to the Nest, the RTH9580WF (wish they gave it a catchier name!) features a beautiful, high resolution touch screen and more nuanced control over your HVAC system and schedules than the Nest does. It’s been on the market for a while, but that doesn’t mean Honeywell hasn’t been keeping it up to date with new things like Alexa support.
