The device that serves as the central point for connected smart home devices is often referred to as a smart hub. This hub acts as a command center, allowing users to control multiple devices through a single interface, often via a mobile app. Smart hubs facilitate communication between devices utilizing various protocols like Zigbee or Z-Wave. They enable automation routines, integrating security cameras, lights, thermostats, and more, enhancing convenience and efficiency. This centralization helps simplify user interactions, offering greater control over the smart home environment.
