IoT Hub: MQTT Broker Service

Turn your Android device into a reliable, lightweight MQTT Broker. Perfect for IoT developers, home automation enthusiasts, and quick testing without needing a Raspberry Pi or a dedicated MQTT server.

IoT Hub is built for stability and efficiency. Leveraging Android's Foreground Services and Wake Locks, this MQTT Server keeps running seamlessly in the background or when the screen is off, ensuring your ESP32, Arduino, Home Assistant, Tasmota, or smart sensors stay connected without interruption.

Whether you are developing a smart home system, monitoring IoT sensors, or need a local server for testing, this app provides the robust connectivity you need.

Key Features:

✅ Persistent Background Service: The MQTT Broker runs reliably even when the UI is closed or the device is locked.

✅ Custom Port: Set your preferred TCP port (default 1883).

✅ Live Logs: View client connections, message payloads, and subscriptions in real-time. Crucial for debugging.

✅ Screen Always On: Optional mode to prevent device sleep during monitoring.

✅ Smart Power Management: Designed to handle Android's battery optimizations and auto-restarts for long-running sessions.

✅ Local & Private: Runs entirely on your local Wi-Fi network. No cloud required, ensuring data privacy for your Smart Home.

Compatibility & Use Cases:

Built on the robust MQTTnet library, the app fully supports MQTT v3.1.1 and MQTT v5.0 protocols. It is tested and compatible with:

Microcontrollers: ESP32, ESP8266, Arduino with Ethernet/WiFi shields, Raspberry Pi, Pico W.

Home Automation Software: Home Assistant, Node-RED, OpenHAB, Domoticz.

Firmware: Tasmota, ESPHome, Shelly devices.

Use this app as a portable gateway or a permanent local server for your network.

Note: This application acts as a Broker (Server). You will need MQTT Clients (like sensors or mobile apps) to connect to it.
