5. Network & Connectivity

SMHUB provides robust and flexible networking options to ensure reliable operation in both enterprise environments and home setups . It can connect via Ethernet, Wi-Fi (2.4/5 GHz), Bluetooth , and optionally via VPN tunnels and DDNS services for secure remote access. 

 

 5.1 Ethernet 

 

 

 Primary interface for stable operation. 

 

 

 Supports 100Mb Ethernet via onboard RJ-45 port. 

 

 

 Recommended for enterprise and multi-device deployments. 

 

 

 Provides lowest latency and highest reliability compared to wireless options. 

 

 

 

 5.2 Wi-Fi 

 SMHUB includes dual-band Wi-Fi with both 2.4 GHz and 5 GHz support. 

 

 

 2.4 GHz 

 

 

 Longer range, higher wall penetration. 

 

 

 Ideal for IoT-heavy environments with many legacy devices. 

 

 

 

 

 5 GHz 

 

 

 Higher throughput. 

 

 

 Less interference in crowded environments. 

 

 

 Suitable for high-speed data transfers and local automations. 

 

 

 

 

 Operating Modes: 

 

 

 Client Mode 

 

 

 SMHUB connects to an existing Wi-Fi network. 

 

 

 Configurable via CLI ( nmcli ) or SSH. 

 

 

 Web UI configuration will be available in upcoming updates. 

 

 

 

 

 Access Point Mode (in development) 

 

 

 SMHUB creates its own Wi-Fi network. 

 

 

 Default SSID: SMHUB-XXXX (last 4 MAC digits). 

 

 

 Default password: smhub1234 . 

 

 

 Useful for first-time setup or when no LAN is available. 

 

 

 

 

 

 5.3 Bluetooth 

 

 

 Bluetooth 5.0 with BLE (Bluetooth Low Energy) support. 

 

 Future updates will expand Bluetooth integration into the web interface. 

 

 

 5.4 VPN (WireGuard) 

 SMHUB includes WireGuard VPN for secure tunneling. 

 

 

 Provides encrypted remote access to SMHUB and connected devices. 

 

 

 Suitable for enterprise remote deployments or secure home use. 

 

 

 Configuration available via CLI or SSH. 

 

 

 Can be combined with DDNS for access without a static IP. 

 

 

 

 5.5 USB Networking 

 When connected via USB-C upstream , SMHUB can act as a network device to the host PC: 

 

 

 Appears as an Ethernet-over-USB adapter. 

 

 

 Provides direct access without needing an external router or switch. 

 

 

 Useful for initial setup, debugging, or portable use cases.
