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.
