status.tpms

This section provides detailed explanations of each field contained in the Tire Pressure Monitoring System (TPMS) status event. These descriptions help integrators and end‑users understand the meaning and purpose of each data element transmitted through Raw Message Streaming (RMS).

Field level Description

FieldTypeDescription
eventSubscriptionIdString (UUID)A unique identifier representing the subscription through which this event was delivered. It ensures traceability between the event and the organization's registered RMS subscription.
eventTypeStringIndicates the category of event generated by the system. For this payload, status.tpms identifies the event as a Tire Pressure Monitoring System status update.
eventIdString (UUID)A globally unique identifier assigned to this specific event instance. Useful for event deduplication, tracking, and audit logging.
assetIdString (UUID)Identifies the physical asset (e.g., vehicle, trailer, equipment) associated with this event. Used to correlate telemetry with a specific asset in fleet management systems.
unitIdStringA unique identifier of the telematics device generating the event. It often includes a namespace (e.g., traxee:) followed by the device's serial or IMEI-like identifier.
eventDataObjectThe eventData section contains sensor readings and associated metadata captured at the time of the TPMS event.
registeredOnDateTime (ISO 8601 timestamp, UTC)The timestamp indicating when the TPMS data was recorded by the system. This value uses Coordinated Universal Time to ensure consistent synchronization across applications.
tpmsArrayA collection of TPMS sensor readings. Each element provides detailed status information for a single wheel or sensor location on the asset.
locationIntegerNumerical identifier representing the sensor's mounting position on the asset. The specific mapping (e.g., "17" → tire position) follows the manufacturer's tire layout configuration.
pressureNumber (Decimal)The measured tire pressure at the time the event was generated. This value enables monitoring of inflation levels for safety and efficiency.
pressureStatusStringIndicates the interpreted status of the tire pressure relative to defined thresholds. Examples include:
extremeOverPressure - Pressure is extremely high compare to recommended limits
overPressure — Pressure exceeds recommended limits
normal — Pressure is within optimal range
underPressure — Pressure is below acceptable limits
extremeUnderPressure - Pressure is extremely low compare to acceptable limits
temperatureNumber (°C)The temperature reading from the tire's TPMS sensor. Monitoring tire temperature helps detect anomalies such as overheating or possible structural issues.
