Recording your data isn't the same as understanding it
Vigilia records every point in your BACnet network. Keywey turns those recordings into answers — automatically surfacing equipment that fights itself, where your energy actually goes, and which zones never hold setpoint. No extra hardware, any controller brand, and every view is a link you can share.
See it on a real building
This dashboard is built live on the public demo building's BACnet data — heat/cool conflicts, where the energy goes, and zone comfort, all derived from recordings.
What Keywey does
Find faults automatically
Keywey flags problems hiding in the trends — heating and cooling running at the same time, zones that never reach setpoint, short-cycling equipment — so you fix issues instead of hunting for them.
See where the energy goes
Break whole-building power into base load, fans, and plant; integrate kW into kWh; normalize consumption against outdoor temperature. Find waste without installing a single new meter.
Build the data your BAS never had
Create virtual points your controllers never exposed — energy from flow, efficiency ratios, conflict flags, comfort compliance — computed from the data you already record.
Analytics you can share
Sunbursts, regressions, status timelines, composite overlays — assembled into dashboards you send as a link or embed in a page, exactly like the demo above.
Vigilia records. Keywey explains.
Vigilia is the recorder: it captures your entire BACnet network, keeps a year of history, and harmonizes it into clean timeseries. Keywey is the analyst: it reads that harmonized data and tells you what it means. Together they take you from raw trends to decisions.
Why Keywey
Lighter than enterprise FDD
Enterprise fault-detection suites are powerful but heavy — costly, complex, and usually consultant-driven. Keywey delivers the high-value diagnostics right in your browser, with no training curve.
Smarter than generic dashboards
Generic BI tools are flexible but HVAC-blind — you build every formula, unit, and rule yourself. Keywey is HVAC-aware out of the box and reads BACnet semantics directly.
Not locked to one vendor
BAS-native tools tie you to one manufacturer and one building. Keywey works across any BACnet system Vigilia records, from any browser.
