Unit history

The prerequisites for accessing the unit history are listed on the Monitoring page.

The History tab provides historical unit data, including trip details, parking intervals, fuel filling, consumption and drains, battery charges and consumption, and events registered after triggered notifications.

To access the unit history:

1. Open the Monitoring tab in the navigation bar.
2. Tap the required unit section.
3. Select the History tab.

The History tab provides the following historical unit data for the selected day:

• Trips, parking intervals, and ignition intervals
• Fuel and battery data: fillings, drains, charges, and consumption
• Events registered by means of notifications

The full-day unit track is shown on the map automatically when you open the tab. For details on viewing and managing tracks, see the Unit track on the map section.

From the History tab, you can also access the unit menu by tapping the icon .

You can adjust the History tab layout. Expand either the unit history or the map by dragging the history section up or down.

The application uses data obtained as a result of message processing in real-time.

The history shows data for the last 300 days.

The data on the tab is presented in chronological order and is formed on the basis of the messages received in the last 24 hours. The data is not formed on the basis of the messages generated more than 24 hours ago (after they are unloaded from the black box).

By default, the data is displayed for the current day. You can get the data for another day in one of the ways described below.

• Select the required day in the calendar.
• Swipe down or up to add the previous or next day to the list. If necessary, repeat the action to add more days.

The top row shows summary information for the day. Tapping this row shows or hides the full-day track on the map.

The summary row includes the following data:

• Trip duration
•  Track length in trips
• Parking duration
•  Total fuel consumption in trips if there is a fuel level sensor
•  Average fuel consumption per 100 km or mi in trips if there is a fuel level sensor
•  Total battery consumption if there is a battery level sensor
•  Average battery consumption per 100 km or mi in trips if there is a battery level sensor

• Fuel and battery data are calculated according to those sensors in the properties of which the Calculate data by the sensor option is enabled in the web version of Wialon. If the option is enabled in the properties of several sensors of one type, their readings are summed up.
• When a trip starts on one day and ends on the next, all the fuel consumed during such a trip is attributed proportionally to both the first and second day at the same time.

• When detecting trips, the Wialon mobile application uses the trip detection settings.
• When a trip starts on one day and ends on the next, its mileage is split into two parts. The first part is added to the summary total for the first day, and the second part is added to the summary total for the next day. This rule applies only to the daily summary (top row). See the Detailed data for the day section for how individual trip data is displayed.

The trip mileage on the History tab may differ from the mileage on the Tracks tab and the Wialon web version. This can occur due to the rounding of values in the mobile app and different data processing methods: for the History tab, data is processed in real time, while for the Tracks tab and most reports in the web version, messages from the database are used upon request. In case of such discrepancies, the value on the History tab is more accurate.

Below is the information displayed for each type of data. To see the place that corresponds to them on the map, tap the required line in the list. The icon in the selected line is displayed in a contrasting color. For example, the icon of a fuel filling changes from  to .

When a trip starts on one day and ends on the next, that trip row is displayed on both the first and second days. Its data, such as mileage, fuel, and duration, is not split and is shown in full. See the Summary information for a day section to learn how the summary total values are calculated in this case.

Icon	Type of data	Available information
	Trip	General information Start time of the trip Duration Track length Maximum vehicle speed Speeding details Indicates that the vehicle exceeded the speed limit. Speed limit. Determined by road limits or a custom value depending on the Advanced tab settings in the web version. Violation duration Speed at the time of the maximum speeding, that is, at the moment of the greatest difference between the permitted and actual speed. May differ from the maximum speed. Difference between the permitted and actual speed at the moment of the maximum speeding Fuel and battery consumption Fuel consumed during the trip: its amount () and average consumption per 100 km () or miles per gallon () for U.S. and imperial measurement systems Battery energy consumed during the trip: its amount () and average consumption per 100 km () or miles The amount of fuel consumed during the trip is determined by the fuel level sensor (FLS); the amount of consumed energy, by the battery level sensor. If there are several sensors of one type, the sum of their values is displayed. The amount of fuel in the application may differ slightly from the resulting data in the reports executed in the web version of Wialon. This can be caused by the following reasons: the fluctuations of the FLS analog data; particularities of division into intervals, and the use of grouping in reports; peculiarities of the algorithm used for calculating and rounding fuel values in the mobile application, which differs from the algorithm in the web version. For details on viewing trip tracks on the map and opening them on the Tracks tab, see the Unit track on the map section.
	Parking	Start time of the parking Duration Parking time with the ignition on Location
	Ignition	Sensor name Time of turning the ignition on Time that has passed since the ignition was turned on This information is displayed if the unit has had the ignition on according to the sensor, but no trip has been detected. The information about ignition is available if the unit has an ignition sensor. To determine the time intervals during which the ignition sensor was on or off, the system takes into account the values of the Maximum interval between messages option in the unit properties and the Timeout option in the ignition sensor properties. The smaller of the two values is used. Learn how sensor operation intervals are determined in the Timeout option description.
	Fuel filling	Time of the fuel filling (time of the greatest difference in fuel level) Amount of filled fuel Location
	Fuel drain	Time of the fuel drain (time of the greatest difference in fuel level) Amount of drained fuel Location If fillings and drains are marked as false in the monitoring system, they are excluded from the history.
	Battery charge	Time of the battery charge (time of the greatest difference in battery level) Amount of charged energy Location

When you open the History tab or select a different day, the full-day track covering all trips is shown on the map automatically. To show or hide the full-day track, tap the summary row for the day.

To see the track for a specific trip, tap the trip row in the detailed data list.

To open the track on the Tracks tab for playback and viewing events, tap the icon . The app navigates to the Tracks tab with the time period preselected: the full day if the summary row is selected, or the trip period if a specific trip is selected.

The History tab can display all events registered by means of notifications with the Register event for unit action. To enable this, activate the Events from notifications in unit history switch in the Notifications section of the settings. You can create and configure such notifications only in the web version of Wialon. See more about the notification notification types.

Depending on the notification type, the registered events are indicated by the following icons:

Icon	Event
	Speed
	Alarm (SOS)
	Parameter in a message
	Connection loss
	SMS
	Address
	Fuel filling or battery charge
	Route progress
	Trailer
	Passenger alarm
	Geofence
	Digital input
	Sensor value
	Idling
	Interposition of units
	Excess of messages
	Fuel drain
	Driver
	Passenger activity
	Maintenance

To see an event on the map, tap the required line in the list. The icon in the selected line is displayed in a contrasting color. For example, the icon of the event for the Speed notification type changes from  to . If the event is registered by means of a notification, the event information displays the notification text.

The icons  and  are used to indicate the beginning and end of the trip, respectively. The segments of the track where speeding was detected are coloured in red.
