What if all the devices in your life could connect to the internet? Not just computers and smartphones, but everything: clocks, speakers, lights, doorbells, cameras, windows, window blinds, hot water heaters, appliances, cooking utensils, you name it. And what if those devices could all communicate, send you information, and take your commands? This is a reality. It is called the Internet of Things (IoT), and it's a key component of home automation and smart homes.

Home automation is exactly what it sounds like: automating the ability to control items around the house—from window shades to pet feeders—with a simple push of a button (or a voice command). Some activities, like setting up a lamp to turn on and off at your whim, are simple and relatively inexpensive. Others, like advanced surveillance cameras, may require a more serious investment of time and money.
