The SMHUB is a professional, Linux-based smart home controller by SMLIGHT, designed to provide stable and full-featured operation for locally hosted control software and automation platforms – all within a single, compact hub. The goal is to enable automation applications (e.g., Zigbee2MQTT, Node-RED, MQTT broker), manage multiple radio networks, and ensure cloud-independent local control from one device.
Unlike traditional gateways that support only one radio and protocol, the SMHUB includes multiple radio modules (Zigbee, Thread, Bluetooth, Wi-Fi) and is optionally expandable with further modules (Z-Wave, 4G/LTE, PoE). It can also run automation apps directly on the hub — no separate server or Raspberry Pi required.
This makes it the ideal choice for advanced users, integrators, and professionals seeking a reliable, modular, high-performance, and future-proof central hub. The SMHUB can even replace a full smart home system while remaining compatible with the most popular platforms and open-source tools.
Brand Introduction – SMLIGHT
SMLIGHT is an innovative brand developing smart home devices with a focus on multi-protocol communication (Zigbee, Thread, Wi-Fi, Bluetooth) and open, local control. Their product range includes gateways, multi-radio adapters, and now full-featured hubs compatible with a wide array of platforms and software such as Home Assistant, Node-RED, or MQTT-based systems. The brand aims to provide seamless integration and cloud-independent automation.
