brianallie/RuView ? reverse-engineered prompt

Build me a local WiFi sensing app that turns cheap ESP32 devices into a privacy first room monitor.

I want it to detect when people are in a room, estimate breathing and heartbeat trends, track movement, and surface simple states like room occupied, sleeping, no movement, and possible distress. It should work without cameras, without wearables, and without sending data to the cloud. Make it easy to run on edge hardware, with a way to connect to Home Assistant and also expose the same room status in a simple dashboard.

Please include the basics for recording WiFi signals, training or loading a model, and viewing live results. If there are any current setup or integration details that are unclear, look up the latest docs online and follow whatever is already in the repo. Keep it practical and polished, with sensible defaults so I can get it running quickly on my own hardware.
