The SmartThings Hub v3 acts as the local brain for a Samsung smart home ecosystem, enabling device-to-device automation that works even without an internet connection. It supports Z-Wave, Zigbee, and Wi-Fi devices from hundreds of brands, reducing the need for multiple manufacturer hubs. Scenes, routines, and automations are set up in the SmartThings app on iOS or Android. Native integration with Samsung TVs, appliances, and Galaxy devices creates a seamless whole-home connected experience. SmartThings Find uses the hub to help locate devices in the home.
