Device Health Extended Report
Track the communication status and usage data from connected telemetry devices, as well if the multiple devices connected to the asset are at the same place.
Overview
The Device Health Extended report provides a concise summary of each asset’s last communication with Perspio and the total distance between multiple devices connected to the same asset.
This report is designed to help users identify devices that may have been installed in different assets, helping correct installation mistakes. If the devices are installed in the same asset, the last column will display a distance of 0 km between the devices, possibly indicating that the devices have been installed in the same asset.
Report Structure
The generated report includes the following data columns:
| Column Name | Description |
|---|---|
| Asset Id | Unique identifier for the asset. Helps distinguish assets across the platform and external systems. |
| Asset Name | The configured display name of the asset. Often includes asset type, registration, or function. |
| Device Ids | List of all telemetry device serial numbers assigned to the asset. Useful for diagnostics, inventory, or replacement tracking. |
| Last Communicated | The most recent timestamp when any assigned device communicated with Perspio. Indicates data freshness and device connectivity. |
| Distance (km) | The total distance between devices connected to the same asset. The closer to 0km, indicates that the devices are most likely in the same asset. |
At the bottom of the report, a generation timestamp confirms when the report was produced, including the local timezone for context.
How to Generate the Report
-
Navigate to Reports → Device Health Extended.
-
Use the asset selector dropdown to choose All Assets or filter by specific assets.
-
Click Run Report.
-
Once generated, results are displayed in a table and can be exported as PDF, PDF/A, XLSX or CSV.
Applicability and Use Cases
The Device Health Extended report is ideal for diagnostics, asset status auditing, and operational data hygiene. Below are typical use cases:
1. Device Communication Audits
Identify devices that have not reported data recently. This can help detect connectivity issues, hardware failure, or power loss.
2. Asset Inactivity Validation
Zero distance travelled in the report indicates that the asset was unused or disconnected, helping support utilisation analysis and resource planning.
3. Device Mapping and Inventory Checks
Cross-check assigned devices by serial number for auditing purposes or prior to device swaps and provisioning.
4. Maintenance Planning
Frequent communication gaps may suggest the need for inspections, power wiring reviews, or replacement of failing devices.
5. Support & Troubleshooting
Useful during support investigations when telemetry data is missing or erratic. Confirms whether communication was established and if motion data was recorded and that the devices are installed in the correct asset.
Interpreting the Data
-
Recent Communication with Zero Distance: The device is online but the asset may not have moved.
-
Old Last Communication Timestamp: Suggests possible disconnection, power cut, or SIM/network failure.
-
Multiple Device IDs: Indicates assets with more than one telemetry unit assigned (e.g., for multi-zone temp tracking or redundancy).
-
Zero Communication & Zero Distance: Asset may be archived, unused, or the device may be decommissioned or faulty. Zero distance indicates the devices are most likely installed correctly, while a distance value over 0 km may indicate that the wrong devieces are linked to the asset.
Summary
The Device Health Extended report gives a deeper operational insight into telemetry uptime and Devices VS Assets Location. It is a critical tool for diagnosing device issues, auditing fleet activity, and supporting proactive maintenance planning. Use it routinely to maintain telemetry reliability and ensure high-quality data across your operations.
