The IIoT stack has new voices — and they’ve been here since the beginning.

We’ve just launched a major update to unpluggediiot.com — new sponsor partnerships, a live architecture explainer, a free resource library, and more. Here’s what’s new, why it matters, and what you should explore first.

● MEET OUR COMMUNITY SPONSORS

INDUSTRIAL DATA OPERATIONS

Canary Labs

Canary Labs is an industrial data operations platform that makes it easy to collect, visualize, and share operational data — without the enterprise price tag. If you’re capturing time-series data from PLCs, OPC-UA, or MQTT sources, Canary is built for that workflow.

MQTT INFRASTRUCTURE

Cirrus Link Solutions

Cirrus Link was co-founded by Arlen Nipper — the co-inventor of MQTT itself. They build the infrastructure that lets industrial systems speak MQTT at scale: brokers, Ignition MQTT modules, and Sparkplug B implementations trusted in critical facilities worldwide.

● FROM THE ARCHIVES — ARLEN NIPPER

Arlen Nipper co-invented MQTT in 1999. He’s appeared on Unplugged three times — and every episode still holds up. If you missed them, now is the perfect moment to listen.

EPISODE 1 · MQTT · DATA COMMUNICATION

Simplifying Data Communication with MQTT

The episode that started it all. Arlen explains how MQTT became the standard for lightweight, reliable machine-to-machine data transport — and why IIoT teams still build on it today.

EPISODE 18 · UNS · IIOT ARCHITECTURE

How UNS Transforms IIoT

Arlen joins Dylan Dufresne to break down the Unified Namespace — the architectural pattern reshaping how industrial organisations think about data flow. Essential listening if you’re designing or inheriting an IIoT stack.

EPISODE 24 · UNS · MQTT · HANDS-ON

Build a UNS Demo

Arlen returns to walk through building a working UNS demo — practical, hands-on, and approachable. If you want to move from theory to implementation, start here.

● NEW ON THE SITE

IIoT Architecture — How the Stack Works

We’ve built an animated, interactive explainer that walks you through the full industrial IoT stack — from edge devices and MQTT Sparkplug B, through the historian layer, all the way to the Node-RED ecosystem. You’ll also see where our partners fit at each layer. It’s the clearest picture of how operational data actually moves.
