1. Introduction

Enterprise-Ready Smart Home Platform

SMHUB is a Linux-based smart home hub designed for reliability, scalability, and openness.
It runs a lightweight Linux OS layer with Node.js preinstalled, making it capable of running major open-source smart applications such as:

• Zigbee2MQTT (Z2M) → enterprise-proven Zigbee integration with MQTT backbone.

• Matterbridge → bridging Zigbee and Thread devices into the Matter ecosystem (Google Home, Apple Home, Amazon Alexa).

• Node-RED → a flow-based automation tool for building powerful automations and integrations.

This software stack ensures SMHUB can be deployed in enterprise projects, system integrator environments, and large-scale smart installations while remaining flexible for continuous growth.

Modular and Scalable

Unlike fixed-function consumer hubs, SMHUB is hardware- and software-extensible:

• Additional radios (Z-Wave, 4G/LTE) can be added via modules or USB dongles.

• System apps can be extended with Node.js libraries or Python scripts.

• Storage options include onboard eMMC and expandable SD card storage.

• Remote management is possible through SSH, VPN (WireGuard), and DDNS services.

This makes SMHUB suitable for smart buildings, multi-site enterprise deployments, and integrators who need a universal controller.

For Home Users & DIY Enthusiasts

While SMHUB is enterprise-ready, it is also accessible to enthusiasts:

• Preinstalled apps → Zigbee2MQTT, Matterbridge, Node-RED work out of the box.

• Web interface → intuitive dashboard for system monitoring and configuration.

• USB passthrough → attach external dongles (Zigbee, Thread, Z-Wave, etc.) for custom setups.

• Ambilight LEDs, IR transmitter/receiver, buzzer, and audio for interactive smart home features.

Whether you’re an integrator managing hundreds of devices across buildings or a DIY user running Home Assistant in your living room, SMHUB adapts to your use case.
