Smart Things allows everyday household objects to be connected to the internet and controlled remotely via a hub and mobile apps. It uses various wireless protocols like Zigbee and Z-Wave to connect devices like motion sensors, door/window sensors, lights and more. The SmartThings hub acts as the central brain that communicates with SmartThings cloud services and paired devices. Users can then monitor and automate devices with SmartApps that trigger actions based on sensor readings or other events. Smart Things aims to make home automation solutions more accessible and user-friendly for broad consumer adoption.
