Setting up MQTT messaging

Butler SOS can use MQTT as a channel for pub-sub style M2M (machine to machine) messages. This page describes how to configure MQTT in Butler SOS.

What’s this?

MQTT is a light weight messaging protocol based on a publish-subscribe metaphore. It is widely used in Internet of Things and telecom sectors.

MQTT has features such as guaranteed delivery of messages, which makes it very useful for communicating between Sense and both up- and downstream source/destination systems.

Butler SOS can be configured to forward metrics and events from Sense as MQTT messages.

Settings in main config file

  # MQTT config parameters
    enable: false
    # Items below are mandatory if mqttConfig.enable=true
    brokerHost: <IP of MQTT broker/server>
    brokerPort: 1883
    baseTopic: butler-sos/          # Topic should end with /
