I'm looking for a way to detect when my cat enters a specific room of the house.
My ideal set up would some sort of sensor in the doorway that triggers a notification of some sort when it recognizes that she has crossed it. I have a dog too, and I don't want him or anyone else to trigger it. Seems like attaching something to her collar that triggers it would work best.
I have a couple of door sensors in my house so that I get an alert when my doors are opened or closed. Something like that seems like it could be a step in the direction I want. But for those, she would have to pass right by the sensor to set it off. I'd want something that would work no matter what part of the doorway she enters.
I've considered pressure mats, doorway chimes like shopkeepers have, just a regular smart sensor, but all of those would result in false alarms. I looked into metal detectors but they don't seem practical. I'm trying to avoid any kind of shock/static collars.
Just curious if anyone has any ideas or knows where else I can look?
