I wanted to share my pet project and first open-source contribution with everyone here!

Here's a summary of what the tool does:

The tool was mainly developed to provide an easy way to integrate Personal Computers into Home Automation and offers a simple, but functional, GUI to connect to an MQTT Broker and listen to a topic.

The user is able to define commands and parameters that should be part of the payload of the MQTT messages received from the broker. For each command/parameter combination the user can then define an executable that should be launched once a certain command/parameter combination is received.

The tool is neatly integrating into the users' environment by sitting in the tray area as a tray icon.

It comes with a Qt5-based GUI and is licensed under the GPLv3+.

If you have any questions about, just ask!

Thanks.
