Downloads

Every building block of the Ethical Saving system to download — device firmware, apps and tools. Offline-first, data-minimal and open in line with our non-profit mission. After downloading, verify the SHA256 checksums.

Note: At MVP stage this system is a comfort/alerting tool, not a medical device. It does not replace nursing or medical judgement. The bridge firmware stores no personal data locally — it runs only inside the secured facility network.

ESP32-S3 Bridge Firmware — v2.3.0

.bin≈ 1.4 MBESP-IDF v6.1

Firmware for the per-room radio bridge: BLE scanner with smartwatch adapter plugins (D20/HryFine, generic Heart-Rate service), WiFi-CSI capture (presence/motion/fall), direct cloud post and signed OTA updates. New in v2.3.0: DFS power-saving + CSI offload (core 1) + stack watchdog (local CSI buffering on SD, survives WiFi outages), board-blink scan (scan-id) for optical bridge location via the camera app, plus a prepared 60-GHz radar hookup (UART). Flash with esptool write-flash 0x20000 es-bridge-firmware.bin (app partition; for a blank board also flash bootloader + partition table).

Patient App (PWA)

.zip≈ 131 KBCapacitor/Vite

Progressive web app for relatives and patients: shows vitals, location and alerts, including the new Neuro Hand Rehab (camera-based, runs right in the browser) and CSI Alarm System controls. Host it over HTTPS in any browser or wrap it into a native Android app via Capacitor (the background safety monitoring needs the native APK below). Unzip and serve from any web server.
