Smart home control units, or hubs, are devices that act as coordinators between different devices and systems in a smart home. These hubs allow different smart devices such as smart lights, smart thermostats, smart security systems and other smart appliances to communicate with each other.

Hubs can use a variety of wireless protocols, such as Zigbee, Z-Wave or Bluetooth, and usually provide a single, centralised interface for managing the various functions of a smart home. Hubs allow users to create automations and schedules, monitor the status of devices and control them remotely via smartphone apps or voice commands.

It is important to choose a hub that is compatible with your devices, as different manufacturers and devices may use different protocols. In addition, smart home hubs may have various additional features such as voice control, security features or integration with large smart home platforms.
