Google’s currently under fire for a recent decision to phase out support for older smart thermostats, but this model isn’t affected and will do the job quite well. In our 2020 review, we found it visually appealing, with a minimal but informative design, and were impressed by its bevy of smart features, including accurate energy monitoring and suggestions for increasing efficiency. It’s a breeze to install, works with many smart home automation systems, and supports scheduling but not AI-powered learning.
