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 moisture sensor allows you to receive alerts, or set connected devices to turn off when a water leak is detected. 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.
