mqtt-panel
A simple web interface for subscribing to MQTT topics and displaying real-time IoT data.
What is mqtt-panel?
mqtt-panel is a web interface that subscribes to MQTT topics and displays real-time data from IoT devices or sensors. It solves the problem of monitoring MQTT-based systems by providing a simple, browser-based dashboard for observing states like temperature, door sensors, or other telemetry.
IoT developers, hobbyists, and system administrators who need to visualize data from MQTT brokers in smart home, industrial, or monitoring setups.
Developers choose mqtt-panel for its minimal setup, responsive design, and focus on real-time data display without the overhead of complex control systems or proprietary solutions.
Overview
A web interface for MQTT
Use Cases
Best For
- Monitoring IoT sensor data in a smart home environment
- Visualizing real-time MQTT messages from industrial equipment
- Creating a simple dashboard for hobbyist IoT projects
- Observing device states without needing control functionality
- Testing MQTT message flows with included sample data
- Deploying a lightweight, self-hosted MQTT web client
Not Ideal For
- Projects requiring interactive control or command publishing to IoT devices
- Teams wanting a modern, component-based dashboard built with frameworks like React or Vue.js
- Environments where MQTT brokers lack WebSocket support or use non-standard protocols
- Applications needing built-in user authentication, data logging, or advanced visualization charts
Pros & Cons
Pros
Host, port, and topic settings are centralized in 'js/index.js', allowing quick setup by editing a few lines without complex build steps or dependencies.
Uses MQTT.js to subscribe to topics and dynamically refresh the web interface as messages arrive, enabling live monitoring as shown in the demo video.
Built with Bootstrap, the dashboard adapts to various screen sizes, evidenced by the mobile screenshot in the README.
Provides a Python script ('test-messages.py') to generate sample MQTT messages, simplifying testing without external data sources.
Cons
Focused solely on monitoring with no functionality to publish messages or control devices, restricting use to passive data display.
Requires an MQTT broker with WebSocket support, which may not be default in all brokers and adds deployment complexity compared to standard MQTT.
Relies on jQuery and older Bootstrap versions, which can lead to integration challenges with modern web apps and potential security vulnerabilities.
