SMHUB is SMLIGHT's professional, Linux-based smart home control center, which provides stable, full-fledged operation for locally running control software and automation platforms - all in a single, compact hub. The manufacturer's goal is to be able to run automation applications from a single device (e.g. Zigbee2MQTT, Node-RED, MQTT broker), manage multiple radio networks and ensure cloud-independent, local control.

Unlike traditional gateways, which support only one radio and protocol, SMHUB has several radio modules (Zigbee, Thread, Bluetooth, Wi-Fi) and can optionally be expanded with additional modules (Z-Wave, 4G/LTE, PoE), and can also run local applications that perform automation directly on the hub — no separate server or Raspberry Pi is needed behind the systems.

It is therefore an ideal solution for advanced users, integrators and professionals looking for a hub that is reliable, modular, high-performance and future-proof. SMHUB can even replace a complete smart home system, while being compatible with the most popular smart home platforms and open source automation tools.
