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. Too proprietary. Too expensive. Too unreliable. Communication was a constant battle. The data was never quite right. For two people who had spent careers demanding precision, it was unacceptable.
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.
To get the firmware and communications architecture right, they brought in Daryl Miller — a 30-year IoT veteran whose expertise in embedded systems and data management transformed what was a working prototype into a scalable platform. With Daryl on board, BluSENSE gained the data 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.
BluSENSE exists because the right tool didn't. Now it does.
Our Mission
“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.”
Complete Solutions
From hardware to data — we provide everything you need to monitor, analyse, and act on building performance. No gaps, no guesswork.
Our Core Principles
Open Hardware
We believe you deserve flexibility and choice. BluSENSE works with a wide range of sensors, communication protocols, and platforms. You are never locked into proprietary technology or a single vendor.
You Own the Data
The data our tools gather belongs solely to you. Always. We process and store it locally on your hardware — and you decide what happens to it from there.
Where We Are Today
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.
