"Hey, Alexa, can you turn the temperature down to 68º?" Of course she can, at least in the millions of homes that have smart thermostats and digital assistants.
Thanks to the Internet of Things (IoT), you can turn down the heat, turn on the lights, adjust the shades, and lock the doors simply by tapping a phone app or talking to a digital assistant. It's the kind of technology you might have dreamed of while watching the Jetsons or a sci-fi movie, but now it's becoming commonplace.
However, the smart home technology is still evolving, so it's important to check compatibility.
