The demo of a smart home from Alex Hawkinson was about the biggest I’ve ever seen. It took up a whole house. Alex, CEO of SmartThings, walked me from room to room in a large Las Vegas home as the house reacted to his presence. In the kitchen, it turned on the coffee maker and announced the weather forecast through a Sonos speaker. It even set the Philips LED lightbulbs to various colors based on how well his stock holdings were doing.
