Looking for some help on a trigger I'm setting up. Can't seem to think of a straightforward way to do it and guessing others have been here long before me..
I have a beam sensor on my driveway (no gates or cameras yet!) and I want to get a text alert once it's triggered and both my wife and I are away. That bit is easy however I don't want to get a message when either of us are arriving home - I'm using the Unifi plugin to determine if we're home or not. What's the easiest way to trigger on beam sensor going "on" and that neither iPhones status becomes up within "x" minutes? So basically if neither phone becomes "up" after someone has come in the driveway I want to know. I plan to experiment with iBeacons at some stage but for now I'm sticking to the Unifi plugin which is working great - thanks Karl.
