Our houses—or, at least, the houses of the tech-savviest among us—are getting closer to running autonomously. Now, it’s not just that you can open your garage door or turn on your living room lights from a smartphone app. Today, many home devices actually are beginning to communicate with each other. Lock the door on your way out and your thermostat shuts off. Or, if you come home and open the garage door, the kitchen lights turn on and the clothes dryer turns up its heat to dewrinkle the clothes that you left in there. Welcome to the brave new world of the Internet of Things (IoT).
