- Motion detection system using Wi-Fi CSI (Channel State Information) without cameras or microphones.
- Requires ESP32-S3 device (~€10), Home Assistant or MQTT server, and ESP-IDF tools.
- Uses mathematical approach (no ML) with 10 extracted features for movement detection.
- Works through walls with 2.4GHz Wi-Fi, optimal range 3-8 meters.
- Applications include home security, elderly care, smart automation, and energy saving.
- Privacy-focused: no personal data collected, only statistical signal metrics.
- Setup time ~30-45 minutes, intermediate difficulty with command line knowledge needed.
- Future potential for ML enhancements like people counting and gesture detection.
- Compatible with IEEE 802.11bf standard for future Wi-Fi Sensing improvements.
- Open-source under GPLv3 license, authored by Francesco Pace.
