As probably many people have pets playing outside once in a while, I'm looking to find a way to know when my cat is at our door or window to get back inside.
During the summer I leave our back window open and our cat can freely go in and out, but with the winter coming I'd rather prefer to keep the window closed to not lose heat.
Then there is also the problem that other animals can get inside, we had a ginger cat visiting us while on vacation and our cat unknowingly still somewhere outdoors, later on when we were back home that cat kept visiting us.
Since I work from home it'll be nice to have a sensor that warns me of any motion or presence with a sound/chime when my cat is next to the window, it's a window where nobody is supposed to be except our cat, so any motion of a live animal could be detected.
As I don't want any false alarms I think a bluetooth BLE solution with a BLE tag would be ideal.
I've seen some products online using batteries and wireless 433 MHz signal, but I'd prefer something more robust and future proof, and not consuming too much power.
Some other ideas/links, but I would prefer to have something working with Shelly devices eco-system.

I was thinking
Some links of BLE projects or similar questions:

So, two options I guess:
1) A classic outdoor sensor which is powered by 230V + Shelly i3
Can such a sensor simulate a pushbutton for example?
2) Bluetooth Low Energy
A BLE sender/receiver setup. When cat with the tag is in range, a chime our notification on my phone via the Shelly app for example...
Anyone here already made something similar in a weather and pet proof way yet?
