• ✅ Compact design – fits everywhere, does not take up space
• ✅ USB Host mode – connect additional Z-Wave devices, 4G modem or USB stick

3 What is SMHUB?

SMHUB is a series of advanced smart home hubs from the manufacturer SMLIGHT, operating on the basis of the proprietary SMHUB-OS system (based on Linux).

This is no ordinary Zigbee adapter – it is a complete platform for building a smart home that:

• 🔹 Runs local automation independent of external servers
• 🔹 Integrates multiple wireless protocols (Zigbee, Thread, Matter, Wi-Fi, Bluetooth)
• 🔹 Allows you to install dedicated applications as in the operating system
• 🔹 Works as a standalone server or home assistant extension

SMHUB-OS layered architecture:

1. Linux kernel – stability and access to hardware
2. Systems – smhub-web (interface) + smhub-services (background services)
3. Applications – Zigbee2MQTT, Node-RED, Matterbridge, Mosquitto, Z-Wave JS

4 Who is SMHUB for?

The SMHUB Nano MG24 is ideal for:

🔰 Beginner smart home users

• Who want a simple start without complicating installations
• They are looking for a ready solution instead of assembling the system from several devices
• They prefer intuitive graphical interface instead of command line

🔧 Advanced hobbyists

• Owning a Home Assistant and wanting to expand the infrastructure
• Planning local automation operating even after the main server failure
• Needing access to the terminal and the ability to install their own software

🏢 Professionals and integrators

• Implementing multi-location installations (multiple SMHUB → one Home Assistant)
• Requiring reliability and redundancy (MQTT Bridge Mode)
• Looking for a platform to prototype IoT solutions

5 How can SMHUB be used?

🔹 1. Zigbee coordinator for Home Assistant

The simplest application – replace the usual Zigbee adapter with a full-fledged hub:

• Run Zigbee2MQTT directly on SMHUB
• Connect to Home Assistant via MQTT (configuration in 2 minutes)
• All Zigbee devices will appear automatically in HA

🔹 2. Matter gateway for Google Home / Apple Home

Share Zigbee devices with Matter ecosystems without additional hubs:

• Install the Matterbridge application (one click in the interface)
• Zigbee2MQTT devices automatically displayed as Matter
• Control them through Google Home, Apple HomeKit, Alexa

🔹 3. Local automation server with Node-RED

Node-RED (preinstalled! ) allows you to create complex automations graphically:

• Drag and combine "blocks" instead of writing code
• Automation works locally on SMHUB even after the main server crashes
• Integrate third-party service APIs (weather, notifications, etc.)

🔹 4. Border Router for Thread/Matter

• Run OpenThread Border Router
• Create a mesh Thread network for Matter-over-Thread devices
• Extend coverage by combining multiple SMHUBs into a single Thread network

🔹 5. Hub Z-Wave (with additional USB adapter)

• Activate USB Host mode
• Connect the Z-Wave adapter via USB hub
• Run Z-Wave JS – control Z-Wave devices

🔹 6. Secure remote access (WireGuard/Tailscale)

• Built-in WireGuard and Tailscale clients
• Secure VPN tunnel without opening ports on router
• Full access to smart home from anywhere in the world

6 Home Assistant – step by step integration

Three ways to connect SMHUB to Home Assistant:

⚡ Option 1: Direct connection via Zigbee2MQTT (most popular)

1. Open SMHUB → Apps → Zigbee2MQTT
2. Enter the address of the MQTT broker: mqtt://IP_HOME_ASSISTANT:1883
3. Enter login credentials for MQTT
4. Enable Home Assistant Settings
5. Save and restart – ready!

Zigbee devices will automatically appear in the Home Assistant.

🔌 Option 1B: ZHA (Zigbee Home Automation) integration

ZHA is Zigbee’s built-in integration in Home Assistant – an alternative to Zigbee2MQTT.

Differences between Zigbee2MQTT and ZHA:

• ✅ Zigbee2MQTT – more advanced, more configuration options, richer network map, larger community, more frequent device database updates
• ✅ ZHA – simpler to set up, built into Home Assistant (no need to install MQTT), less resource consumption, ideal for beginners

How to connect SMHUB via ZHA:

1. In Home Assistant go to Settings → Devices and Services → Add integration
2. ZHA (Zigbee Home Automation)
3. Select connection type: Network (socket://)
4. Enter address: socket://IP_SMHUB:8888 (default port for EFR32)
5. Click Submit – Home Assistant will automatically detect the coordinator

💡 Which option is right for you?

• 🔹 Zigbee2MQTT – if you want maximum control, advanced features and the best compatibility with your devices
• 🔹 ZHA – if you prefer simplicity, minimalism and do not need advanced options

Both methods work great – the choice depends on your preferences!

🔄 Option 2: MQTT Bridge (for advanced)

Pros: SMHUB maintains its own MQTT broker that syncs with HA. Automations on SMHUB work even after Home Assistant server failure!

1. In SMHUB enable Bridge Mode in MQTT settings
2. Set up a remote broker (HA address)
3. Set Bridge theme: #both 1
4. Save and restart

This mode ensures maximum reliability and redundancy.

1 1 Why is SMHUB Nano the best first smart home hub?

If you are just starting your adventure with a smart home, you are faced with a dilemma: “Do you buy a simple Zigbee adapter or maybe a Raspberry Pi right away? "

SMHUB Nano solves this problem:

🎯 You don’t have to choose between simplicity and power

For starters: You use SMHUB as a regular Zigbee coordinator – simple interface, easy setup, “click and it works”.

After a while: You discover Node-RED, Matter, local automations, your own scripts – without buying new hardware!

🚀 Investment for years

• 📌 Thread/Matter ready – new standards already built in
• 📌 Regular updates – the manufacturer is actively developing SMHUB-OS
• 📌 Open platform – install your own applications, no limits
• 📌 Expansion without replacement – you add functions by installing the application, you do not buy new equipment

❤ Who is SMHUB NOT for?

Let’s be honest – SMHUB Nano is not for you if:

• ❌ If you only want Zigbee and nothing else – buy a regular adapter for PLN 150
• ❌ You do not have a router with an Ethernet port in range – then it is better SLZB-06 (Wi-Fi)
• ❌ Looking for a ready-made closed ecosystem (Philips Hue, IKEA) – this device for open standards

But if you want:

• ✅ Start straight and have the option to develop
• ✅ Avoid buying equipment "extended" which you will later throw away
• ✅ Have full control and independence from the clouds
• ✅ Save time (ready solution instead of RPi configuration)

...this SMHUB Nano is PERFECT to start with!
