Notification Time Filters help prevent excessive, unnecessary alerts. The Time Filters hold back the alerts for a certain period, and send out the notification after the sensor status has been in effect for a configurable period of time, this results in canceling alerts if their status returns to normal within a predefined time period.

In the above illustration, the Time Filter is set to 10 seconds. In the first picture, the temperature sensor senses a temperature of 67 degrees, which has been defined as a Critical status. However, the status only stays Critical for 6 seconds before returning to Warning and then Normal. Therefore, no alarm will be sent out. The second picture indicates the temperature level in a Critical status for longer than 10 resulting in a notification being sent to targeted people.
