Then in your python application:

from led_indicator_messager_package import led_messager

#mClient = led_messager.LEDMessager(username, password, "GREEN") # initialise for paid version with colours

mClient = led_messager.LEDMessager(username, password) #initialise for free version "LED"

mClient.connect()

mClient.send()

The host is ledmqtt.devsoft.co.za and the port is 9001

Sending MQTT from the front end is possible but not secure as your username and password will be visible in the console
