I'm working on a send alerts throw E-mails when a car has enter the geofence.
To do that I have INPUT as IVMS data then we have FILTER ( geometry enter geofence ) and that will give us an OUTPUT as E-mails.
But I facing a problem that when the car dosen't enter the geofence and stay inside (not exit) the geofence and the data refreshed in IVMS database I got the same e-mails over and over again from the same car.
I just want one e-mail when the car enter the geofence even if it is not get out from the geofence.?
