The idea of a home that can take care of its inhabitants has been around for over 100 years. But only in the last few decades have we seen technological breakthroughs that can make smart homes a reality. In the first episode of a 7-part series on the future of the smart home, Andrew traces the history of the smart home and presents a vision of its future as a multitude of devices are being connected to the Internet. Interviewee Episode Excerpt The Long Awaited Smart Home Revolution It’s the dead of winter and you’re driving home. In my case, it’s to my house outside of New York City on the eastern end of Long Island. I remember coming home in the dead of winter and huddling with blankets on the couch until the place warmed up. The use case for a thermostat that could be accessible over the Internet was so obvious, I wondered why it took until 2011 for Nest to launch. It would have been prohibitively expensive for me to heat a weekend home throughout the week, and a timer wouldn’t work, as I was never really sure I was going to be at the house on a weekend. The perfect solution: a thermostat that could be remotely accessed from a smartphone over the Internet to turn on the heat as I’m on the highway and still a couple of hours away from getting home. That’s what Nest does. It’s a thermostat that is connected to the wireless network in your home. There’s a corresponding downloadable app for your Android or iPhone that, when you open it, shows you the temperature of the room. If you have multiple zones in your house, you can see the temperature in each zone. You can even see the temperature outside of your house. Best of all, there’s a friendly interface that allows you to adjust the temperature upwards or downwards. In my case, I typically pull over in traffic on the Long Island Expressway about an hour away from my home to adjust the temperature. You’d be forgiven if you thought that the Nest was the first instance of a connected device that was part of the smart home. The truth is that people have been talking about and building some variation of a smart home for decades. When I refer to a smart home, I’m referring to a house featuring “intelligent” technology that simplifies and automates everyday activities such as turning on lights, locking the door, lowering shades, and, yes, changing the settings on your thermostat. You can call any device “smart” that is capable of doing something autonomously. A smart thermostat automatically adjusts the heat downward if there isn’t any motion in my house. That’s what makes it autonomous. Smart devices are almost always also devices that are connected to a network. The first connected locks and light switches introduced to the home more than a decade before Nest weren’t even connected to the Internet. They were connected to a stand-alone device in the house (called a bridge) that you could operate remotely only if you were in the house. The catch: they were connected from the lock or the light switch to the bridge using protocols like Z-Wave and Zigbee. Think of a protocol as a language for one device to speak to another. WiFi is also a protocol, but it couldn’t be found in these early devices. In 2004, you could operate connected locks and connected lights from a mobile device, but not an iPhone, because the iPhone wasn’t launched until 2007. It’s not hard to see why your average consumer had difficulty getting excited about this type of configuration. First, you needed a dedicated remote control to make these devices work. Second, they only worked when you were inside of your house. Fast forward to 2011 and Nest and a time when most people you knew had a smart phone. While Nest wasn’t the first smart thermostat, they captured the tech community’s imagination with a clever interface and by putting a WiFi chip inside their thermostat that connected it to the Internet.
