diehard79/WiFi-People-Detection-System ? reverse-engineered prompt

Build me a WiFi based people detection app that can tell when a room is empty or occupied, and also estimate how many people are there, using RSSI signal changes from a few routers.

I want it to work in real time, with a simple API that can return the latest detection, accept feature data for prediction, and stream live updates over WebSocket. Include a realistic WiFi simulator so I can test it without hardware, plus the signal processing and machine learning logic to extract features and make predictions. If the trained models are missing, have it generate synthetic data and train itself on startup.

Please also add a basic frontend or demo view if that fits, so I can see the current room status, people count, and confidence at a glance. Make sure there is a calibration flow for setting a room baseline, good test coverage, and easy local setup with clear run instructions. If you need to check current docs or best practices, look them up online.
