How It Works with Plaspy
When connected to Plaspy the TK121‑S transmits location and event data so fleet managers can view live positions, receive alerts, and generate reports. Plaspy ingests GPS and LBS positions, ignition status, and alarm events and presents them through dashboards, route playback, and notification rules to support operational oversight.
- Real time location updates delivered to Plaspy for live map visualization and fleet monitoring
- ACC ignition status reporting to support engine cycle tracking and ignition based rules
- Displacement, speed, and geofence alarms to trigger immediate alerts and event logs within Plaspy
- Optional relay control for immobilizer workflows that can be managed through the platform or via remote commands
- Remote configuration and firmware friendly operation to reduce onsite maintenance and speed deployments
Typical Use Cases
- Fleet management for light commercial vehicles monitoring routes, speed behavior, and ignition events
- Anti theft and immobilizer workflows that combine ignition detection with remote relay control
