You don’t have to turn your lights on anymore, they’re already on for you. And off when you’re not around.
In just about ten minutes, I programmed our living room lights to be fully automated. Using smart plugs, door sensors, and motion sensors, our lights turned on right when the door opened, and stayed on until there was no motion in the room for 30 minutes. It sounds a bit more complicated than it was; imagine swiping through a friendly mobile app and selecting a few “if this, then that” scenarios. Largely painless. SmartThings also seamlessly networks with a range of lightbulbs — so it's as easy as screwing in a lightbulb, literally.
