About Mr. IIoT

We don't just talk IIoT. We build it.

Mr. IIoT is an industrial IoT and systems engineering firm — the people manufacturers call when they're growing faster than their systems can keep up. We connect the machines, integrate the software, and automate the busywork, so the team you already have can do more.

Why Mr. IIoT

More than IIoT — a systems engineering partner.

We engineer the whole system

Sensors, protocols, software, dashboards, and the ERP/EDI plumbing behind them — we design and build the entire pipeline, not just one box.

We span IT and OT

25+ years bridging the plant floor and the enterprise — the rare team fluent in both controls and code.

We're vendor-neutral

Open standards, JSON and MQTT, no lock-in. Your data is yours, and you can change platforms without breaking connectivity.

We're open by reputation

Manufacturers find us through our open-source work on GitHub and stay for the depth behind it.

We solve, not sell

"Experts who are here to help us solve a problem, not just to sell a product." We embed with your team and get it done.

We speak every machine

Fanuc, Haas, Siemens, Yaskawa, PLCs, robots, CNCs, databases — 50+ protocols, normalized into one coherent picture.

The founder

Chris Misztur, President & Founder

Mr. IIoT is led by Chris Misztur, who brings 25+ years of industrial IoT and Industry 4.0 experience from the Greater Chicago Area. His philosophy is simple: policies created at the boundary — the edge where machines meet information — are the key to digital transformation and to manufacturers truly owning their data.

That hands-on, problem-first approach is why clients describe working with Mr. IIoT as gaining "a hired gun" — technical expertise that complements their own engineering team.
