# ESP32 Hacking TODO

## Firmware
- [ ] On-device CSI processing (send metrics, not raw)
- [ ] Deep sleep mode with wake-on-CSI-motion
- [ ] Battery-optimized duty cycling

## Tools (esp-ctl)
- [ ] Multi-sensor BLE correlation (zone tracking by source sensor)

## Testing
- [ ] Benchmark: CSI callback latency
- [ ] Benchmark: UDP throughput at different rates
- [ ] Power consumption measurements (per-mode: idle, CSI, BLE, probe)

## Documentation
- [ ] Pin mapping for ESP32-DevKitC V1
- [ ] Compare CSI quality: passive (router) vs active (ESP-NOW)
- [ ] Multi-sensor deployment guide (placement, zones, triangulation)

## Ideas
- ESP-NOW mesh for direct ESP32-to-ESP32 CSI
- External PIR sensor for CSI ground truth validation
- AP+STA config portal (captive portal for initial setup)
- Multi-channel scanning (hop across WiFi channels)
- RSSI triangulation with 3 sensors (approximate device location)
- BLE device fingerprinting (identify phone models by advertisement patterns)
- Historical presence logging (who was here, when, how long)
