How It Works with Plaspy
The AT-20 transmits location and vehicle telemetry to Plaspy using its LTE and GSM/GPRS links over TCP/GPRS and SMS. Plaspy ingests those feeds for real-time tracking, alerts and historical route playback. Integration is straightforward: GPS positions, timestamped telemetry, alarm events and input states arrive in standard telematics formats and are rendered in Plaspy dashboards, maps and reports.
- Real-time location and telemetry updates delivered to Plaspy via 4G/LTE or quad-band GPRS.
- Vehicle status: ACC (ignition) on/off detection and motion events are reported for fleet workflows.
- Event alerts: geofence entry/exit, over-speed, SOS emergency messages and motion alarms appear as Plaspy notifications.
- Fuel monitoring: remote fuel cutoff supported and optional fuel sensor integration reports fuel telemetry to Plaspy.
- Historical track playback provided to Plaspy for trip analysis and compliance reporting.
