Sensor notification

Is there way to set up a notification that an entry sensor has activated during armed away status , and I should expect a disarm signal to follow , or call police, or would the crash and Smash detection essentially cover and take care of that for me?

You can set up notifications for sensor activity, but yes you are essentially describing the purpose of Crash and Smash detection, which is not something that requires active monitoring by the user, it is automatic.
