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 presence sensor allows you to receive alerts if your pet leaves unexpectedly, set connected devices to turn on and off as people come and go, 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.
