MQTT IoT Controller

This app uses the MQTT protocol (v3.1.1 & 5.0) to control and monitor your IoT devices. It provides a complete set of features for efficient and flexible device management:

🔗 Connect to multiple MQTT brokers simultaneously.

🔖 Save multiple connections: Switch between them with a single tap.

📌 Subscribe to multiple topics per broker: Easily follow different channels at once.

🔔 Background & Push Notifications: The app stays reliably connected in the background. Subscribe to specific topics and receive real-time push alerts for the events that matter most to you.

📤 Publish to multiple topics per broker: Send several messages in parallel to the connected broker.

💾 Automatic saving of subscriptions and messages: Pick from the list and re-publish with a single tap, faster and more convenient.

👀 Broker-specific view: Only the subscriptions and messages of the connected broker are shown. When you switch broker, you’ll only see that broker’s data.

🧩 Create customizable widgets: Dynamically add, edit, and remove widgets to customize your dashboard exactly as you like.

⏱️ Session Expiry Interval (MQTT 5.0): Take full control of your connection by defining exactly how long the broker should retain your session state after a disconnection.

🏷️ User Properties (MQTT 5.0): Attach custom key-value pairs to your message headers, allowing for advanced metadata handling and routing.

⏳ Message Expiry Interval (MQTT 5.0): Set a strict lifespan for your published messages to ensure that outdated commands or data are never delivered late.
