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.

I'm obsessed with smart home tech and channel my obsession into new stories for Consumer Reports. When I'm not writing about products, I spend time either outside hiking and skiing or up in the air in small airplanes. For my latest obsessions, follow me on Facebook and Twitter (@danwroc).
