Independent Measurement · Continuous Telemetry · Verified Field Work
Bluefin puts its own sensors on your mechanical equipment and reads physical reality directly — over cellular, with no building network involved. When a contractor works on that equipment, the visit can't be filed without evidence, and it lands in your portal attached to the machine. Both halves are running on real equipment today. The same units also serve Bluefin's commissioning work — deployed to verify or troubleshoot equipment during a project, or left in place for ongoing monitoring.
Real readings from Bluefin units on working equipment, captured Aug 21, 2026 with both machines under load. This page shows a saved snapshot — the live view lives in the owner portal, not on this website.
Running today
A condensing unit and a gas furnace have been streaming continuously for months — every five minutes, eight to nine channels each. One is a refrigeration cycle; the other is combustion and air handling. The field unit on both is the same board. What changes between them is configuration, not hardware — and that interchangeability is the point. The readings below were captured on a 90°F afternoon with both machines working.
A control system can be told a comfortable lie. A jumpered freezestat reports "satisfied" no matter what the air is actually doing, and a trend log pulled from that controller will agree with it. Bluefin's sensors don't ask the controller anything — they measure the air, the current, and the machine itself.
That's a different claim from reading a building's own data, and it's the one worth paying for when the question is whether equipment is genuinely performing.
During commissioning & troubleshooting
The same independent measurement that runs continuously in the owner portal is also a field instrument. On a commissioning project or a troubleshooting call, Bluefin puts its own units directly on the equipment — reading physical reality, independent of the building's controls — to prove a system performs, or to find out why it doesn't.
During functional testing, a control system can report a sequence as satisfied while the equipment behaves otherwise. A unit on the machine measures the physical result — temperature, current, pressure, vibration — across the full test window, independent of the BAS. The evidence is the equipment's own behavior, not a trend the controller agreed with.
When a machine short-cycles, won't hold setpoint, or trips intermittently, the answer is often in data the building never logged. Put a unit on it and watch continuously — every few minutes, for as long as it takes — until the fault shows itself. Intermittent problems a spot reading misses surface in a continuous record.
After a repair, a rebalance, or a sequence change, the same unit shows whether behavior actually changed — before-and-after on the real signals, not a paper sign-off. The record stays, attached to the equipment, if the building is one Bluefin keeps monitoring.
Getting equipment data the usual way means coordinating the controls vendor, getting onto the building network, and hoping the right points were ever trended. A Bluefin unit needs none of it — no vendor, no IT ticket, no BAS integration; just physical access to the equipment. It mounts on the machine and streams over its own cellular link, so it's deployed and collecting the relevant data in a single visit.
The hardware measures; the reading is Bluefin's — an experienced commissioning engineer interprets what the signals mean and what to do next.
Proven end to end
Monitoring tells you something changed. This is the other half: making sure the work that follows actually happened, and that you can see it. The full path below has been run on real hardware over cellular — tag to portal.
An NFC tag on the equipment opens the right job on the technician's phone. No app store, no login hunt, no typing an asset number into a form — the machine identifies itself.
A guided checklist specific to that equipment type, with photo capture built in. Required evidence is enforced: the visit can't be closed without it.
Signal drops in basements and on roofs. A submitted visit is written to the phone and holds there until it can upload, so a dropout on the way out of the building doesn't cost the technician the report. Sync status is visible on screen, so the technician knows before leaving site whether anything hasn't reached the office.
The completed visit appears against that piece of equipment, attributed to the right contractor and the right technician — with the photographs attached.
How it works
Temperature, current and vibration measured directly at the equipment. Cellular-connected, configured per equipment type, no building IT involvement.
Every reading lands in a secure cloud every five minutes and is kept — months of per-channel history, queryable rather than sampled during a site visit.

Physical-impossibility checks run hourly against both machines — a discharge line colder than the suction line, a condenser rejecting no heat. They need no baseline and no tuning, so they work from the day a unit is installed, and they have found nothing wrong in thirty days. They evaluate only while a machine is running, because that is the only time they can be true or false.
What is not running is the part that reaches you. Per-unit baselines are being computed but nothing reads them yet, degradation trending is not built, and nothing sends you a notification — an alert today is something you would have to go and look at.
Where the line is
Bluefin's whole value is independent verification. It would be a strange way to earn that to overstate the product. So, plainly:
Same machine, same morning. With the compressor off, the vibration channel sits at 0.004 g. Five minutes later, drawing 7.1 A, it reads 0.276 g — a 69× separation, and the channel tracks every cycle of the compressor without being told the compressor is running. That's a clean, trendable signal for "this machine is behaving differently than it was."
It is not a diagnosis. Overall RMS tells you something changed; it does not tell you which bearing, or when it will fail. Anyone selling you the second thing on a sensor like this is selling you something else.
On the roadmap
Monitoring and the field service record are running. The list below is in development — undated on purpose, because a date on this page would be a guess.
Physical checks run today and write a real alert; the path was proven by constructing a check that had to fail. Baseline and rate-of-change detection, and pushing a notification to a person rather than leaving it in the portal, are what remain.
Each machine compared against its own normal, binned by operating condition, so a hot afternoon isn't mistaken for a fault. The baselines are being computed; the checks that read them are not switched on.
Long-run drift on the channels that matter, surfaced as a trajectory rather than a single reading.
A commissioning professional reads your building's data and tells you plainly what it means and what to do next — judgment on top of the numbers.
Turning a flagged issue into a scoped request that carries the equipment context and data a contractor needs — then collecting and awarding bids against it.
Before-and-after data confirming the fix actually changed the machine's behaviour — proof rather than a paper sign-off.
Adaptable by design
Because Bluefin measures the signals every mechanical system shares — temperature, current, vibration — a condensing unit and a furnace run on the same board with different sensor populations. That's already demonstrated across two live units, not a design intention. Adding an equipment type is a configuration job.
Who it's for
You subscribe, and you own the record. See what your equipment is actually doing, and see every service visit against the machine it happened on — with photographs, a technician's name, and a timestamp. No engineering report required to read it.
Invite the contractors who already service your building. They get a phone tool that opens the right job from a tap on the equipment — no account hunt, no asset number to type. Their work is documented against real data, and they remain users in your building.
Early access
Monitoring and the verified field record are running on real equipment today. Early-access buildings get instrumented first and help shape what the intelligence layer flags — and what it stays quiet about.
