Depending on the conditions of triggering, notifications in Wialon are divided into types which you can select when creating the notification. 

The measurement system applied to the settings of each notification is the same as the measurement system of the resource to which the notification belongs.

Below are all the possible notification types and the parameters available for them.

Speed

For this purpose, configure the following options:

Below are the steps to configure a notification of the Geofence type.

1. Select when the notification should be triggered:
   • when the unit enters the geofence (Inside geofence);
   • when the unit leaves the geofence (Outside geofence).
2. Select the resource whose geofences should be displayed in the list (select All available to view the geofences of all available resources).
3. In the left list, select the geofences or groups of geofences (displayed in square brackets) for which the notification should be triggered. You can use the dynamic filter above the list to search.
4. Using the icon , move the items from the left list to the right one.
   
5. In the Advanced options section, if necessary, specify the additional conditions under which the notification should be triggered. It can be the range of speed values (the Speed option), and/or the range or the difference of the selected sensor values (the Sensor value option).
6. Select the logical operator on the basis of which the notification should be triggered if several geofences are selected. The OR and AND operators are available.
   

Logical operators for a unit inside the geofence

Logical operators for a unit outside the geofence

Sensor Value

• Value range. Allows specifying a range of sensor values to control whether the received values fall in it or not.
• Value change. Allows specifying one value to control whether the received values exceed it or not.

For the Value range method, follow these steps:

1. In the drop-down list, select the sensor type and/or in the Sensor name field, specify the name mask using special characters (* and ?).
2. In the Similar sensors drop-down list, select one of the available options:
   • Sum up values. The values of all sensors of the selected type and/or sensors with the same name mask are summed up. Thus, the sum of all values is taken into account before the notification is activated.
   • Calculate separately. The values of all sensors of the selected type and/or sensors with the same specified name mask are controlled separately.
3. Specify the minimum and maximum values of the sensor.
4. Select the activation type:
   • In range. The notification is activated when receiving values which fall in the specified range, including the values specified as minimum and maximum ones.
   • Out of range. The notification is activated when receiving values which don’t fall in the specified range.

For the Value change method, open the same-name tab on the right and follow steps 1 and 2 from the instruction above. In the Delta field, specify a difference when exceeding which the notification should be triggered. The sensor values can be increased or decreased because the specified delta is compared with the module (for example, |12 − 10| = 2 and |10 − 12| = 2).

Connection Loss

1. Select when the notification should be triggered: when the connection is lost or restored. You can select both options.

2. Select in what way the connection loss should be detected:
   

   Control type	Description
   No coordinates	If this option is selected, the connection loss refers to the absence of coordinates in the unit messages or the absence of the messages themselves. It may happen that messages with sensor data are sent but they don't contain data on the unit location (for example, if the GPS antenna is closed).
   No data	If this option is selected, the connection loss refers to the absense of any messages from the unit.

3. In the Time interval field, specify how long the connection loss should last in order for the notification to be triggered. The maximum allowed value is 999,999,999 minutes.
4. If necessary, specify if the unit should be inside or outside a certain geofence as an additional condition for triggering the notification. To configure the Geofences option, follow steps 1–4 from the guide on configuring the notification of the same name.
   

Off Time

In the Max allowed off time field, you should specify for how long a vehicle can be parked; and in the Speed, no more than field, you should indicate what speed shouldn't be exceeded during off time.

To avoid situations where the notification is triggered because of the device inaccuracy, it is advisable to specify a speed value of more than 0 km/h, for example, 1–5 km/h.

If the Sensor value option is activated, the notification is triggered only if all the specified conditions are met: off time duration, speed, and the sensor value. For example, you can receive notifications when the unit is parked with the engine or attachments running. This option is configured in the same way as the notification type of the same name.

SMS

Interposition of Units

To configure a notification, follow the steps below.

1. Select when you want to receive the notification: when the unit is moving away from another unit or approching it.
   
2. Move the units you want to monitor to the right part of the window. To find the required unit, use the dynamic filter above the list.
   
   
   

3. In the Radius field, specify the distance between the units upon the reduction or increase in which the notification should be triggered.

4. If necessary, set additional conditions for the notification: unit speed and sensor value. The latter option is configured in the same way as the notification type of the same name.
5. In the Logic operator section, select how the specified conditions should be applied in case several units are selected. If the OR option is enabled, the notification is triggered when the unit approaches or moves away from any of the selected units. If the AND option is enabled, the notification is triggered when the unit approaches or moves away from all the selected units simultaneously.
   

Address

Excess of Messages

To configure a notification, follow the steps below.

1. Select the type of messages: data messages or SMS messages.
2. In the Reset counter each field, specify the time interval for which you want to set a limit on messages. 
3. In the Limit of messsages field, specify the number of messages after exceeding which the notification should be triggered.

In the example from the image above, the notification is triggered if 3 or more SMS messages are received from the unit within 24 hours.

Fuel Filling

In the Sensor masks option, you can specify one or several masks of the sensors that should be used for detecting fuel fillings and their volume.

If the Ignore recalculated data option is enabled, the notification is received only once after a filling is detected.

If the Geofence option is enabled, it is an additional trigger condition whether the unit is inside or outside a certain geofence during the filling. To configure the option, follow steps 1–4 from the guide to the same-name notification type.
