The parameter which allows you to prevent the accidental triggering of the notification caused by tracker errors (for example, in case of false exits from the geofence). You can also use this parameter, for example, to specify the minimum duration of speeding or other alarm states for which a notification should be triggered.

Specify the minimum duration of the alarm state in seconds, minutes or hours and select a unit of time in the drop-down list. The maximum allowed value is 24 hours (1440 minutes, 86,400 seconds).

The maximum number of times the notification can be triggered. When this limit is reached, the notification is automatically disabled.

The option is applied to all notification triggers of all the units or unit groups controlled by this notification. For example, 5 is indicated in the Max triggers field of the notification that controls 2 units. The notification is disabled when the sum of triggers for both units reaches 5.

You can set a time limitation for this parameter (icon ). In this case, the limit on triggers is applied only to the specified intervals, that is, the notification can be triggered any number of times outside of these intervals.

Generate notification*

The parameter which allows you to select when the notification should be triggered. Two options are available: For all messages and Only when state changed.

"For all messages" option

To receive the notification each time the unit device sends a triggering message, select the For all messages option.

"Only when state changed" option

To receive the notification only when a certain state of the unit changes, select the Only when state changed option. If you select this option, make sure the unit state is not triggering at the moment you enable the notification. 

The system monitors state changes by comparing every unit message with the previous one. If the last received message contains a parameter value which matches the conditions for triggering the notification and the previous message contains one which doesn't, the notification will be triggered. In the case of the notifications of the Sensor value and Parameter in a message, if the previous message doesn't contain the required parameter or its value is invalid, the system analyses the 5 messages received before the last one. If there is a message with a valid value among them, it is used instead of the previous message.

The Only when state changed option applies to all the notification triggering conditions at once. 

Example. There is a notification of the Geofence type which tracks the unit location within a geofence. Advanced options, such as Speed and Sensor value, are specified for the notification so that it is triggered when the speed is higher than 60 km/h and a custom sensor value is from 5 to 10. The Only when state changed option is selected. Such a notification is triggered in the following cases:

• when the unit enters the geofence at a speed exceeding 60 km/h, and the custom sensor value falls within the range of 5 to 10;
• when the unit has been in the geofence for some time, its speed is higher than 60 km/h, and the custom sensor value, which wasn't within the specified range, changes to one that falls into it. 
• when the unit has been in the geofence for some time, the custom sensor value falls within the range of 5 to 10, and the unit speed, which was lower than 60 km/h, changes to one that exceeds 60 km/h. 

The parameter which allows you to prevent unnecessary triggering. Available if the Only when state changed option is selected for the Generate notification parameter.

If the time which passes before the beginning of the alarm state is equal to or greater than specified in this parameter, a notification is triggered. This prevents repeated triggering in cases where the alarm state is interrupted for a short period of time.

Specify the minimum duration of the previous state in seconds, minutes or hours, and select a unit of time in the drop-down list. The maximum allowed value is 24 hours (1440 minutes, 86,400 seconds).

Example. A user has configured a notification of the Speed type with the range of allowed speed from 0 to 60 km/h. The specified minimum duration of the previous state is 2 minutes. This means that if the speed is exceeded, the notification will be triggered only if there have been no speed limit violations for at least 2 minutes after the last triggering.

If a time limitation is configured for the notification and the beginning of the previous state falls within this limitation (is outside the specified time frame), the system takes into account the entire interval of the previous state. That is, the notification will be triggered if this interval is greater than the specified value.

The setting which allows you to specify the time and select the days and/or months during which the notification parameters should be controlled. For example, they can be controlled only on weekdays and within working hours, or only on odd days, and so on. You can learn how to set a time limitation below.

Unlike the time limitation applied to the Max triggers parameter, this setting takes into account the time the message was generated, and not the time it was registered on the server. Therefore, even if a message generated on the specified day or interval is unloaded from the black box at a time when the notification parameters shouldn’t be controlled, the notification is still triggered. The exceptions are the notifications of the Alarm and Connection loss types where the time of the message registration on the server is taken into account.
