The MQTT connection parameters are given by the hostname, port, username, password, version, usetls and topic attributes. If no authentification is needed, username and password need to be empty. The version attribute excepts three values: 3 for MQTT 3.1, 4 for MQTT 3.1.1 and 5 for MQTT 5.0. If the MQTT connection is TLS encrypted the usetls attribute should be set to true, false otherwise. The MQTT topic can be filtered with the topic attribute, the default value is # (everything).
