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: * Display: Shows a numeric value or text (scrolling it) * Gauge: Shows a numeric value over a graded scale * LED: Shows the value of a topic as a LED on or off * Graph: Shows the values of a topic as a graph * Switch: Writes a value to the topic depending on the switch position * Secure Switch: Similar to the Switch Widget. To operate the switch, the protection has to be remove with a click on the yellow bands though * Switch & LED: Writes a value to a topic and shows its value as a LED on or off * Knob: Writes a value to a topic proportional to the position of the knob * Slider: Writes a value to a topic proportional to the position of the slider * Push Button: Writes a value to a topic when the button is pushed and another value when it is released * Text: Writes the value entered by the user to a topic 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 * documentation to use the Adafruit IO service instead of your MQTT broker.
