3. Getting Started

This section explains how to unbox, power, and access your SMHUB for the first time. 

 

 3.1 Unboxing 

 Inside the SMHUB package, you will find: 

 

 

 SMHUB main unit 

 

 

 2x 5dB antennas 

 

 

 Quick start guide 

 

 

 (Optional, depending on order) PoE module , UPS module , or 4G/LTE module 

 

 

 ⚠️ Some accessories such as 18650 batteries (for UPS) , SIM card (for LTE) , or external antennas may need to be purchased separately. 

 

 3.2 Powering SMHUB 

 SMHUB supports multiple power options. Choose the one that fits your setup: 

 

 

 USB-C Power (default) 

 

 

 Connect the included USB-C cable to the USB-C (upstream/power) port on the back of the device. 

 

 

 Use a 5V/2A USB-C adapter. 

 

 

 

 

 PoE (Power over Ethernet) (requires PoE module) 

 

 

 Install the PoE add-on module. 

 

 

 Connect SMHUB to a PoE-enabled Ethernet switch (802.3af standard). 

 

 

 

 

 UPS Module with Batteries (optional) 

 

 

 Insert supported 18650 Li-ion cells into the UPS board. 

 

 

 Connect the UPS board to the main unit. 

 

 

 SMHUB will automatically switch to battery power during outages. 

 

 

 

 

 Solar/DC Input via UPS (optional) 

 

 

 If using the UPS module, SMHUB can also be powered from an external DC or solar supply. 

 

 

 

 

 ⚠️ Important: Thanks to integrated USB power switching logic , SMHUB automatically detects whether it should act as a host (powering peripherals) or device (drawing power). 

 

 3.3 Network Connection 

 You can connect SMHUB to your network in different ways: 

 

 

 Ethernet (recommended) 

 

 

 Connect an Ethernet cable to the LAN port. 

 

 

 SMHUB will obtain an IP address via DHCP. 

 

 

 

 

 Wi-Fi Client Mode 

 

 

 Connect via CLI/SSH (see section 3.4). 

 

 

 Use the nmcli command to scan and connect to your Wi-Fi network. 

 

 

 Web-based Wi-Fi setup is in development. 

 

 

 

 

 Wi-Fi Access Point Mode 

 

 

 On first boot, SMHUB may start in AP mode. 

 

 

 SSID: SMHUB-XXXX (last 4 characters of MAC). 

 

 

 Default password: smhub1234 . 

 

 

 Connect and then open the web UI. 

 

 

 

 

 

 3.4 First Access 

 Once powered and connected, you can access SMHUB in several ways: 

 Web Interface 

 On the first SMHUB models (with old firmware) the web interface will be on port 3000 To it access use: http://smhub.local:3000 

 If you have such a device, we strongly recommend that you immediately update it via USB according to this guide Old firmware has critical issues that have been fixed in the new version! 

 

 

 Open a browser and go to: 

 

 

 http://smhub.local (mDNS) 

 

 

 or the IP address assigned via DHCP. 

 

 

 

 

 SSH Access 

 

 

 Connect from a terminal:  ssh smlight@smhub.local

 

 

 

 Default credentials are user: smlight , password: smlight 

 

 

 Use SSH for advanced configuration and Wi-Fi setup until the web Wi-Fi interface is fully implemented. 

 

 

 USB-C Upstream Mode 

 

 

 If connected via the USB-C upstream port , SMHUB may appear as a network device to your host machine. 

 

 

 This allows direct connection without a router. 

 

 

 

 3.5 First Boot Behavior 

 

 

 The system automatically starts Zigbee2MQTT service. Other services like Matterbridge and Node-RED  could be run manually afterwards. 

 

 

 Service LEDs and RGB LEDs will indicate boot sequence and status. 

 

 

 On first login, you should: 

 

 

 Change the default password (via web UI or SSH). 

 

 

 Configure your preferred network connection (Ethernet or Wi-Fi). 

 

 

 Update system software (see Section 4). 

 

 

 

 

 

 3.6 Safety Notes 

 

 

 Always use certified power supplies when running from USB-C. 

 

 

 If using the UPS module, only install good quality18650 cells . 

 

 

 Ensure proper ventilation - SMHUB is designed for continuous 24/7 operation.
