Our Story
How We Started
BluSENSE was born out of frustration.
When water physicist Dr. Markus Lenger and building science expert Gary Klein were tasked with monitoring heat pump water heater performance across four buildings in San Bernardino, California, they assumed the hard part would be the analysis. It wasn't. The hard part was finding technology that actually worked.
They tested solution after solution.
So they built their own.
Starting from first principles, Markus and Gary designed a system around one idea: that building data should be accurate, secure, accessible, and owned by the people who collected it. Edge computing — processing and storing data on site rather than routing everything through the cloud — became the foundation. No vendor lock-in. No data held hostage. No timestamp errors from server delays. Just clean, precise, real-time data from every sensor in the building.
Water physicist and electrical engineer with over 35 years of experience in wastewater and building systems. His patented monitoring systems formed the technical foundation for BluSENSE.
Building science expert whose field experience in hot water systems and energy performance shaped the real-world design philosophy behind every BluSENSE product.
A 30-year IoT veteran whose expertise in embedded systems and data management transformed a working prototype into a scalable platform — bringing BluSENSE the security, latency performance, and reliability that demanding deployments require.
The result is a hardware platform built the way Markus and Gary wished something had existed when they needed it — flexible enough to handle hundreds of sensors, powerful enough for the most complex building environments, and simple enough to deploy without an army of specialists.
Our Mission
Why We Do It
At BluSENSE, our mission is simple: to build building performance monitoring hardware that actually works — and that professionals at every budget level can afford to deploy. No compromises on accuracy. No vendor lock-in. No data held hostage. Just reliable, field-tested technology that gives you the visibility to make better decisions about the buildings you manage, own, or commission.
Our Core Principles
What We Believe
Data is only valuable when it tells you something you can act on. We build systems that don't just collect readings — they give you the clarity to understand what your building is actually doing, and why it matters.
Proprietary platforms, vendor lock-in, and data held on someone else's servers are industry norms we reject. BluSENSE works with the sensors, protocols, and platforms you choose — and your data lives on your hardware, not ours.
When you pay for a monitoring system, the data it generates is yours — not a resource for someone else's business model. We process and store everything locally, on your device. What you do with it from there is entirely your decision.
BluSENSE was born in the field, not a product roadmap. Every design decision is shaped by actual buildings, actual deployments, and professionals who need hardware that performs when conditions aren't perfect.
The Name Behind the Brand
What Blu Means
Blu isn't just a name — it's a commitment to three things every professional who relies on building data deserves.
Raw sensor data is noise. BluSENSE turns it into something you can understand, trust, and act on — giving you a clear picture of how your building is really performing.
Sensors, systems, buildings, and people — all linked. BluSENSE bridges the gap between field hardware and the professionals who depend on that data to make decisions.
Always on. No gaps, no interruptions, no data lost to power cuts or network failures. The insight you need is there when you need it — not just when conditions are perfect.
Where We Are Today
From One Project to a Commercial Platform
BluSENSE has evolved from a custom-built solution for a single project into a commercial hardware platform trusted by leading organisations across the building performance, water efficiency, and energy management sectors.
Our product line — BluCORE, BluNODE, and BluPULSE — is designed to work together seamlessly or independently, giving professionals the flexibility to monitor exactly what they need, at the scale they need it.
Every product we make is designed, built, and tested in California. Your data stays on your hardware. And we're just getting started.
