SMLight has released the SMHUB Nano Mg24, a compact Linux-based smart home hub that eliminates the need for a separate Raspberry Pi or mini PC to run home automation software. The device combines a SOPHGO SG2000 RISC-V SoC with a Silicon Labs EFR32MG24 wireless MCU, creating an all-in-one solution that runs Zigbee2MQTT, Node-RED, and other automation tools directly on the hardware.
The SG2000 processor offers either a 1GHz C906 RISC-V core or a 1GHz Arm Cortex-A53 core selectable at boot, paired with 512MB of RAM and 8GB of eMMC storage. The MG24 wireless chip handles Zigbee, Thread, Matter, and Bluetooth connectivity with transmission power up to 19.5 dBm. The hub also includes 10/100Mbps Ethernet with PoE support, WiFi 6, and a USB-C port for expansion. An optional UPS module accepts standard 18650 batteries and can even connect to a solar panel for off-grid installations.
The device runs SMHUB-OS, a Linux distribution that comes pre-installed with Zigbee2MQTT, Node-RED, Matterbridge, Mosquitto MQTT, Z-Wave JS UI, and WireGuard. Users can write automations in Bash, Python, or Node.js, or create visual flows with Node-RED. Beyond standalone operation, the hub can serve as a Matter bridge to Google or Apple ecosystems, or function as a remote coordinator for platforms like Home Assistant. The SMHUB Nano Mg24 measures 16 cm (6.3 inches) long and is available now starting at $43 (€40).
