Your smart home needs a brain, so get started with a SmartThings hub. It connects wirelessly with a wide range of smart devices and makes them work together. Next, add some smart devices and put your home to work. For example, the SmartThings multi sensor allows you to check whether you closed the front door, window or garage, receive an alert if doors or windows open unexpectedly, set connected lights, speakers, cameras, and thermostats to turn on and off as you open doors or windows, and much more. Finally, use the SmartThings app or Amazon Alexa to control your smart home. Teach your house the tricks by telling it what to do when you are asleep, awake, away, and back home.
