Udemy – Unified Namespace: MQTT, OPC UA & Sparkplug B Masterclass

In this hands-on masterclass, you will build a complete industrial data pipeline on your own laptop using entirely free tools. No vendor lock-in. No cloud subscription required. No hardware needed. Just your machine, a working internet connection, and the same open-source stack that real plants are deploying right now.

WHAT YOU WILL BUILD:

• A complete end-to-end Unified Namespace — from OPC UA source through
• Sparkplug B encoding, MQTT brokering, Python subscribers, time-series
• storage, and live Grafana dashboards. Every layer. Every connection.
• Every failure mode tested.

THE STACK YOU WILL MASTER:

• Ignition Edge — as OPC UA client and Sparkplug B publisher
• HiveMQ Community Edition — as your MQTT broker
• Eclipse Tahu — the Sparkplug B reference library
• Python with paho-mqtt — custom publishers and subscribers
• Node-RED — low-code MQTT subscriber in five minutes
• InfluxDB v2 — time-series historian for plant data
• Grafana — live plant dashboards from real data
• Azure IoT Hub — cloud bridge for multi-site analytics
