Best Smart Home Devices of 2021

Consumer Reports has no financial relationship with advertisers on this site.

The “home of the future” has been promised for decades, but smart home devices like the Nest Learning Thermostat and Amazon Echo are finally making it a reality. By 2025 it’s estimated that there will be more than 70 million smart homes in the U.S., and yours might very well be one of them.

Here at Consumer Reports, we put these products through rigorous tests, such as analyzing the sound quality of smart speakers, judging the cleaning capabilities of robotic vacuums, and evaluating the data security of cameras and doorbells to help you avoid hacks.

The result of all that work? Our in-depth ratings for smart speakers, wireless security cameras, video doorbells, DIY security systems, smart locks, smart thermostats, robotic vacuums, and smart sprinkler controllers.
