Google's most affordable smart thermostat, the Nest Thermostat, is currently on sale for $100 (it's usually $130). With a typical retail price at more than double the Amazon Smart Thermostat, the Nest Thermostat really needs to offer something unique to make it worthwhile. 

Overall, it's a solid smart thermostat that works in the Google Home app and with both Alexa and Google Assistant smart speakers and displays. However, like the Amazon Smart Thermostat, it doesn't work with Apple HomeKit. (At least, not yet.)

Its main standout feature is the design. The Nest Thermostat has the same rounded shape as the flagship Nest Learning Thermostat and comes in four finishes: snow (white), sand (rose gold), fog (a light blue-green gray) and charcoal (dark gray). The touch control on the right side of the thermostat isn't as functional for lefties as the Learning Thermostat's dial, but it worked well enough in my testing. 

This is also an excellent option if you're set on Nest as your smart home platform of choice. That way, you can control all of your various connected devices from the same Google Home app and even create advanced automations in the app or with a Google Assistant voice command.
