    May also be specified with the MQTTUI_RETAIN environment variable.

-v, --verbose
    Show full MQTT communication

-b, --broker=URL [default: mqtt://localhost]
    URL which represents how to connect to the MQTT broker. Examples: `mqtt://localhost` `mqtt://localhost:1883` `mqtts://localhost` `mqtts://localhost:8883` `ws://localhost/path` `ws://localhost:9001/path` `wss://localhost/path` `wss://localhost:9001/path`

    Username to access the mqtt broker. Anonymous access when not supplied.

    May also be specified with the MQTTUI_CLIENT_CERTIFICATE environment variable.

--client-key=FILEPATH
    Path to the TLS client private key. Used together with --client-cert to enable TLS client authentication. The file has to be a DER-encoded ASN.1 file in PKCS#8 form serialized to PEM.

--insecure
    Allow insecure TLS connections

-h, --help
    Print help (see a summary with '-h')
