How It Works with Plaspy
When used as a Plaspy compatible tracker, the OTK02-4G sends GNSS positions and OBD-sourced telemetry to the Plaspy platform (via cellular data or SMS). Plaspy ingests location, event and diagnostic messages into dashboards and alerts so fleet managers and vehicle owners can monitor status, trigger alarms and generate reports in real time.
- Real-time location and telemetry updates delivered to Plaspy’s web and mobile apps for live monitoring.
- Engine on/off and ignition status detected through the OBD II interface — available in Plaspy event logs.
- Mileage and trip history reported via OBD for maintenance planning and utilization tracking.
- Alarms (geo-fence, towing/movement, overspeed, battery low) forwarded as instant notifications through Plaspy.
- Offline logging: 2 MB flash stores data during GSM/GPRS blind spots and syncs when connection resumes.

Why Choose This Tracker with Plaspy
The OTK02-4G combines simple OBD II plug-and-play deployment with robust telemetry and offline resilience, making it a practical Plaspy compatible option for both single vehicles and scaled fleets. Its OBD diagnostics deliver actionable data — mileage, engine on/off events and trip logs — while AGPS and the device’s offline logger reduce data gaps for reliable real-time tracking and historical playback. For fleet managers seeking dependable telemetry, anti-theft alerts, and easy integration into Plaspy’s dashboards, the OTK02-4G offers a low-friction solution backed by a free platform, OEM support and a two-year warranty. It complements broader monitoring strategies (including fuel monitoring workflows and Bluetooth sensor deployments available through Plaspy integrations) without requiring complex hardware installation.
