mqtt-panel

A simple web interface which is able to subscribe to a MQTT topic and display the information.

The screenshot shows an example how to keep track on what's going in your apartment or your house. It's not about controlling, this setup is about observing various states.

The web page is using bootstrap with jQuery.

Prerequisites/Installation

Get the files

Clone the mqtt-panel repository

$ git clone git@github.com:fabaff/mqtt-panel.git

Dependencies

mqtt-panel is using the listed projects to provide its functionality:

• paho-mqtt
• mqtt
• socket.io

If you are using Fedora and want to generate MQTT messages, install the paho-mqtt Python bindings.

$ sudo dnf -y install python-paho-mqtt

MQTT broker/server

A MQTT broker/server is needed to run on localhost on port 3000 and providing websocket support.

• hbmqtt - MQTT broker with build-in websockets capabilities
• mosca - A multi-transport MQTT broker for node.js
• mosquitto - An Open Source MQTT v3.1 broker

Running mqtt-panel

1. Make sure that your MQTT broker/server is running and listening. Or run ./mqtt-server.py to use mqtt-panel with hbmqtt (make sure that you installed it with pip3 install hbmqtt).
2. Adjust var host = '127.0.0.1'; and var port = 3000; in the file index.html to match your setup.
3. Open index.html.

Running mqtt-panel with node.js

If you are using Fedora, just use dnf to install node.

$ sudo dnf -y install node npm

then

$ npm install mqtt socket.io

1. Launch ./runner.sh which will start the node server on port 3000 for the standard node.js example.
2. Adjust var host = '127.0.0.1'; and var port = 3000; in the file index.html to match your setup.
3. Open index-node.html with your browser.

Generate MQTT messages

Start the ./test-messages.py script to publish test messages if you have no other source for messages. Depending on your broker you may need to set the supported version. On line 33: protocol=mqtt.MQTTv311

For manually sending messages to your MQTT broker/server you can use mosquitto_pub from mosquitto or hbmqtt_pub.

$ mosquitto_pub -V mqttv311 -h localhost -d -t home/front/door -m "false"

To check if the messages are are ok, subscribe to the topic home/# with mosquitto_sub.

$ mosquitto_sub -V mqttv311 -h localhost -d -t home/#
