Installation of MQTT Explorer

MQTT Explorer is an open-source MQTT client that provides a graphical user interface to communicate with MQTT brokers. It offers convenient ways of configuring and establishing connections, creating subscriptions or publishing on topics. The program presents all data clearly and in well organized sections but also enables the user to select which data should appear on the monitor, should be hid or dumped in a file. Additionally it provides tools to decode the payload of messages, execute scripts or track the broker status.
