What is a MQTT?
MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
This package aims to collect published MQTT messages by subscribing to an MQTT broker and subscribing to a topic. The MQTT v3.1.1 protocol is supported over unencrypted TCP connections with the optional use of username and password credentials.
The topic is used to classify data received and extract text and numeric indicators by class of topic.
