I’ve recently been using Smartthings to help keep an eye on my elderly parents. My mother’s doing mostly ok, but my father has moderate dementia.
I’ve been using a presence sensor combined with door sensors to make sure that if he tries to leave the house in the middle of the night, it’ll turn on a few lights and alert my mother (and myself remotely through my phone). So far, that works great! (and so far, he hasn’t left - just opens and closes the door at night - phew!).
But what I’d REALLY love, is a SmartApp that would let me set an alert if my father leaves the house WITHOUT my mother. Obviously it’s fine if they go out together, but I’m worried about my dad leaving on his own - either in the middle of the night again, or during the day when my Mom’s left him alone to run errands or something.
I.E. An alert if one of two presence sensors departs the area without the other one - maybe with a variable time window I could set (likely a few minutes). Or, if presence sensor A leaves after presence sensor B has already left outside of another variable window.
Does that make sense? Can anyone lend a hand here?
