Hi everyone, I'm the author of ESPectre.

This is an open-source (GPLv3) project that uses Wi-Fi signal analysis to detect motion using CSI data, and it has already garnered almost 2,000 stars in two weeks.

Key technical details:

- The system does NOT use Machine Learning, it relies purely on Math. — Runs in real-time on a super affordable chip like the ESP32. - It integrates seamlessly with Home Assistant via MQTT.

Interesting! Are you familiar with tommysense.com? I think it doing something similar? Did not yet have time to try it.

Tommysense creates a sensing mesh between devices, while ESPectre uses your existing Wi-Fi router as the transmitter. As a result, ESPectre needs only one device per area but requires a compatible router with solid 2.4 GHz coverage. The overall goal is similar, but ESPectre is open-source!
