SMHUB Nano Mg24 compact Linux-based Zigbee/Thread Smart Hub combines SG2000 RISC-V SoC with MG24 wireless MCU

SMLight’s SMHUB Nano Mg24 may look like the company’s earlier SLZB-06p Zigbee to Ethernet/WiFi/USB coordinators, but it’s a more powerful Linux-based Zigbee/Thread Smart Hub that pairs SOPHGO SG2000 RISC-V SoC with Silicon Labs MG24 multi-protocol wireless MCU.

Unlike traditional Zigbee/Thread adapters that connect to a host through USB or Ethernet, the SMHUB Nano Mg24 is an all-in-one solution that runs all major automation apps directly on the device, eliminating the need for a Raspberry Pi, Mini PC, or other hardware server.

The Nano Mg24 smart hub runs SMHUB-OS Linux distribution (likely based on OpenWrt since it relies on opkg package manager) with Zigbee2MQTT, Node-RED, Matterbridge, Mosquitto MQTT, Z-Wave JS UI, WireGuard, and other packages. It supports upgrades through OTA or opkg, and runs automations using Bash, Python, NodeJS, or Node-RED flows.

As previously noted, it’s designed as a complete standalone hub, but it could also be used as a Matter bridge to Google/Apple ecosystems, or a remote radio coordinator for platforms like Home Assistant, OpenHub, HomeSeer, and so on.

The SMHUB Nano Mg24 can be purchased for $42.99 on the SmartLight shop and $44.99 on AliExpress’s Smlight or ANTVLED shops. It might be cheaper on AliExpress for Black Friday/Cyber Monday 2025, as you can use coupon codes like CNX04USA or CNX04W to receive a $4 discount. Finally, it might eventually show up on Amazon with other products from the company.
