MQTT Manager

MQTT Manager


MQTT Manager is a general-purpose application to read and write topics on a MQTT broker through a friendly interface based on widgets.

The application is organized in 4 tabs and each tab can contain any number of widgets. Widgets are chosen between the available ones.


The application includes:

  • a complete user manual

  • documentation to learn the MQTT basics

  • the documentation to install a private MQTT broker on:

    • Raspberry Pi

    • Linux

    • macOS

  • the documentation to use the Adafruit IO service instead of your MQTT broker. This allows to get started in a few minutes, without installing additional software

  • Arduino ESP32, Arduino MEGA, Arduino Nano 33 IoT and MKR1000 sketches to create a MQTT node which sends data to the application and can be controlled by it
