I have two cats and want to track in which of the 6 rooms of my flat (about 96 square meters) they currently are. Later I would like to trigger an alarm if they get into a "forbidden" room. The cats are currently not wearing a collar, but I tried it once and it could work, even though they are not very thrilled about it.
I would prefer an affordable solution and if possible no equipment on the cat itself - especially nothing that need to be charged.
I first thought of RFID, placing a passive tag on each cat and a sensor on each door. But I don't have any experience with it and don't know if it is even possible to detect if the cat is sitting in front of the door or actually crossing it - and how the direction (entering of leaving the room) could be tracked as well.
Another idea was to use small Wifi modules like the ESP8266, track the signal strength of two independent WiFi networks and calculate the position, but I don't think it's accurate enough, and there are many APs around here.
Do you have any idea what might work?
After some misunderstandings I'd like to clarify some parts
- I'm not looking (necessarily) for a cat-specific solution. It doesn't need to reasonable as well (neither it has to be the next big thing). I want this, even though everyone may think it's stupid.
- Yes, cat's can somehow be trained. That's not the point. I want to look on some display and check where they are. That's all.
- It should be (if possible) const- and energy efficient. (i.e. no autonomes patroling drones ;))
