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.

You may be surprised to find out how machine learning works!

That's a fair point, and as a math graduate, I absolutely agree that ML is fundamentally applied math.

When I say 'No ML,' I mean there is no training phase, no labeled data needed, and no neural network model used to infer the rules.

The distinction here is that all the logic is based purely on signal processing algorithms.

Thanks for raising the point!
