How It Works with Plaspy
Integrating the PT23 with Plaspy gives parents and operators a streamlined monitoring experience. The watch sends location and status messages over TCP, UDP or SMS to iStartek’s server or directly to Plaspy-compatible endpoints. Plaspy ingests those messages to provide live maps, alerts and historical playback so you can respond quickly to SOS events, geo-fence breaches or routine check-ins.
- Real-time location and telemetry updates sent via TCP/UDP or SMS for live tracking on Plaspy dashboards.
- Two-way audio and remote voice monitoring available for direct communication and situational assessment.
- SOS events: dedicated button triggers immediate alerting and call capabilities integrated into Plaspy workflows.
- Smart geo-fence alerts and historical route playback (up to three months) for route review and attendance verification.
- Device status telemetry (battery level, reporting mode) and configurable triggers (time, distance, mileage, low-battery) for automated notifications.

Why Choose This Tracker with Plaspy
The PT23 paired with Plaspy offers a focused solution for child-centered tracking that balances accuracy, durability and cost-effectiveness. Its multi-mode positioning and MTK GNSS chipset deliver reliable outdoor accuracy, while Wi‑Fi and LBS provide indoor fallback so Plaspy can present comprehensive location data. Two-way voice, SOS and configurable alerts give you actionable events instead of raw coordinates, and iStartek’s server access model eliminates ongoing platform fees — you only cover local 2G SIM costs.
While the PT23 is purpose-built as a wearable GPS tracker for kids and does not include features such as fuel monitoring, ignition control or immobilizer functions, Plaspy supports a broad range of telemetry and control features for other compatible devices. That makes the PT23 a straightforward Plaspy compatible choice for organizations and families who need dependable real-time tracking, geo-fence protection, and simple integration into existing monitoring workflows.
