Fledge South MQTT Publisher plugin, Default MQTT version is v3.3.3; Use either MQTTv31 or MQTTv311.

The MQTT broker service should be running.

The example given here are tested using mosquitto http://test.mosquitto.org/

$ sudo apt install -y mosquitto
$ sudo systemctl enable mosquitto.service

Install paho-mqtt pip package.

python3 -m pip install -r python/requirements.txt

Install plugin in your local Fledge installation

sh install-plugin.sh

Run Subsciber Test Script

$ mosquitto_sub -t "YourTopic" -h "localhost" -p 1883
{
    "operation":"YourTopic",
    "parameters":[{
        "name":"example",
        "value":{...}
    }]
}

The mosquitto_sub command should be ran right after installing and initializing Fledge and will await MQTT payloads from the specified host. The South MQTT Publisher will await MQTT commands from the active North plugin and send them to the subscribed clients, such as the mosquitto example client.
