Setting up MQTT messaging
These settings are optional.
If you don’t need the MQTT feature, just disable it and leave the default values in the config as they are.
Do note though that Butler expects the configuration properties below to exist in the config file, but will ignore their values if the related features are disabled.
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.
