Sections in detailed unit information
Detailed unit information is based on the unit properties and can only be edited in the web version. After a long tap on the line with the property, its value is copied to the clipboard.
This information can include the following sections:
| Tab | Description |
|---|---|
| Custom fields | The custom fields added on the same-name tab in the web version of Wialon. |
| Sensors | The sensors for which the Visible option is enabled on the Sensors tab in the web version of Wialon. The order of sensors depends on their order configured on the tab. Tap on a sensor row to view a chart with historical sensor values. See the Viewing sensor data section for more details. If filtration is configured for a fuel level sensor, the unit information shows its filtered value. The unit section, by contrast, displays the raw value. You can choose how fractional values of sensors should be rounded in the user settings in the Wialon web version. |
| Profile | The unit characteristics specified on the Profile tab in the web version of Wialon. |

Viewing sensor data
Unit details provide historical sensor data in an interactive chart format. This feature allows you to monitor equipment activity, analyze trends, and diagnose issues, like engine overheating or fuel drain.
To access historical sensor data, navigate to the Info tab and tap the row of the required sensor. The data is displayed in a chart with the x-axis representing time and the y-axis representing the sensor value. The chart can display only numerical values.
Once you’re viewing the chart, you can perform the following actions:
- Select a date: Tap a specific date to view the data for that day. If there is no data, the page displays No data.
- View exact values: Tap a point on the chart to see its precise value and timestamp. These values are displayed according to the filtering and rounding settings from the web version and include units of measurements if they are configured for the sensor.
- Zoom: Use a pinch gesture to zoom in or out on the chart.
- Navigate the chart: To navigate a zoomed chart, swipe left or right on the screen.
- Expand view: Drag the page border up or down to switch between a full-screen view and a split view showing both the map and the chart.
