Share

A major week for fleet intelligence — fuel monitoring with automatic fill and drain alerts, a completely overhauled trip detection engine, a new start/stop trip report, automated ignition calibration, and significant improvements to real-time tracking reliability.


Fuel Monitoring and Alerts

Automatic fuel event detection

The platform now detects fuel fill and drain events in real time. When your vehicle's fuel level changes significantly during or between trips, the system automatically generates an alert and logs a fuel entry in your account — no manual input required.

Configurable alert types

Two new alert types — Fuel Fill and Fuel Drain — are available in your alert configuration. You can enable them per vehicle or fleet-wide, and they appear alongside your existing alerts in the dashboard and notification channels. Drain alerts are particularly useful for detecting potential fuel theft.

Trip fuel estimation

Each trip now includes an estimated fuel consumption figure, calculated from the vehicle's fuel sensor data and tank capacity. This gives you a per-trip cost breakdown without needing to manually log fuel stops.


Trip Detection Overhaul

More accurate trip data

The trip detection engine has been rebuilt for accuracy. Average speed calculations are now correct, odometer readings are captured at trip start and end, and validation gates prevent false trips from being recorded. The result is cleaner trip history with reliable distance and duration figures.

Driver behaviour in trips

Driver behaviour events — harsh braking, rapid acceleration, sharp cornering — are now linked directly to the trip they occurred in. This makes it easy to review driving quality on a per-trip basis rather than checking separate reports.

Improved reliability

Several edge cases have been resolved: trips that were left open due to connection drops now close automatically, race conditions during cleanup have been eliminated, and GPS outlier detection has been relaxed for buffered messages received after a device restart.


Start/Stop Trip Reports

New report type

A new Start/Stop Trip report is now available in the Reports section. It pulls data from the trip history table and shows each trip with start time, end time, duration, distance, and fuel consumption. The report is available in JSON, PDF, and Excel formats, and can be scheduled like any other report.


Ignition Auto-Calibration

Automated threshold tuning

For supported devices (FMC003 and FMB003), the platform now automatically calibrates the ignition detection threshold. The system reads the current device voltage profile, compares it against known patterns, and applies the optimal setting — eliminating false ignition events caused by voltage fluctuations.

Voltage profile sync

Device voltage profiles are synced daily from the tracking server and used to assign devices to the correct calibration group. Pending calibrations are applied automatically, with full audit trail visible to your account administrator.


Tracker Command Improvements

Better retry logic

Tracker commands now have configurable retry limits with exponential backoff, preventing commands from being sent indefinitely to offline devices. You can also manually override a pending command if the automatic retries are not needed.

SMS command fixes

SMS commands sent to trackers now include the correct device credentials, resolving an issue where some commands were rejected by devices that require authentication.


AVL Maintenance Notifications

Real-time maintenance status

When the tracking server undergoes maintenance, you now see a clear banner in the dashboard indicating the current status. Notifications are debounced to avoid repeated alerts during brief interruptions, and a polling fallback ensures you stay informed even if the WebSocket connection drops.

Channel toggles

Administrators can now control which notification channels are used for maintenance alerts — in-app banners, push notifications, email, and WhatsApp — from the admin panel.


Real-Time Tracking Reliability

Out-of-order update protection

A fix prevents stale location updates from reverting a vehicle's status. Previously, if messages arrived out of order (e.g., an older "idle" message arriving after a newer "moving" message), the vehicle could briefly show the wrong status. The system now checks timestamps and discards outdated updates.

Ignition debounce fix

Ignition state changes triggered by the device itself (OnChange events) now bypass the debounce timer, ensuring that real ignition events are reflected immediately on the map without delay.


Additional Improvements

Health check reliability

Health check notification emails now validate recipient addresses before sending. Invalid email addresses are automatically disabled, preventing delivery failures from blocking the entire notification batch.

Billing enforcement

Overdue invoice enforcement banners now redirect to the correct billing page, and the enforcement logic properly respects per-account overrides set by administrators.
