How to get notifications when any device connects or disconnects? Using Nighthawk app on iPhone

[woodlaw809]

Hello all -- is there a way to configure the Nighthawk app so that I get notifications whenever any device connects and disconnects to wi-fi? I get notifications when a new device connects, but other than that, nothing.  We are a small office and it would be very helpful to me (all alone upstairs) to monitor who is coming & going (downstairs).  Any info is appreciated; thanks much.
