MQTT Sparkplug Lens

MQTT Sparkplug Lens is a tiny command line utility that dumps all the Sparkplug messages in colored JSON format. This tool makes it easy to view and analyze MQTT Sparkplug messages in a human-readable format.

Usage

Before using the tool, you need to set the environment variable MQTT_BROKER in the following format:

MQTT_BROKER=tcp://test.mosquitto.org:1883

You can replace the value with your broker's URL. Currently, the tool only supports MQTT brokers without any authentication. You can run the tool using the following command:
