v2.0 — MyGeotab Add-In

One click. 30 seconds.
Tells your fleet manager exactly who to call, what to fix,
and by when — with dollar amounts attached.

Zero Infrastructure Single JSON File 30-Second Audit

Built by Sanjaya • February 2026

The Problem

100+ reports.
Zero action plans.

MyGeotab tells you what happened. A fleet manager still has to open 5–6 reports,
cross-reference manually, figure out what matters, decide who handles it,
and somehow track if anything got done.

Key Breakthrough

3-Way Fault Classifier

Cross-validation found 3 vehicles misclassified as mechanical failures —
actually accelerometer mounting issues. Wrong classification sends a mechanic for a firmware problem.

🔧
Mechanical
Real engine DTCs from FaultData API. Recurring codes = component failure.
→ SEND TO MECHANIC
Demo-32: Low Priority Warning Light ×2
Demo-19: Low Priority Warning Light ×4
📱
Device Noise
Accelerometer triggers from loose Geotab GO device. Looks like faults — isn't.
→ SEND TO IT / GEOTAB
Demo-39: 15 Engine Fault Exceptions
Demo-40, 41, 42: all accelerometer
👤
Driver Behavior
Speeding, hard braking, cornering from ExceptionEvent rules.
→ COACHING SESSION
Speeding · Harsh Cornering
Hard Acceleration events
Evidence-Backed

Every finding has proof.

Not just "Demo-31 idles too much" — the tool shows when, how long, and the pattern.

🔥 Demo-31 — Top Idler
