Nest pioneered the smart thermostat category and the 4th Gen adds improved AI scheduling and a sleek design that works without a C-wire. The go-to pick for anyone deep in the Google ecosystem.
The best sub-$100 smart thermostat by a wide margin, with occupancy sensing and Alexa Hunches built in. A no-brainer for Alexa and Ring households.
All the core Ecobee reliability at roughly half the price of the Premium. Works flawlessly with Alexa, Google Home, and Apple HomeKit for users who don't need the built-in speaker or air quality monitor.
Comes with a remote room sensor in the box so you can monitor two areas of your home from day one. The best pick for larger homes where one thermostat can't tell the whole story.
