How floor detection works
1. Barometric pressure — each floor is ~12 hPa lower than the one below. The phone's pressure sensor detects this change and estimates the floor number relative to the ground floor baseline set at login.
2. BLE beacons (production) — low-energy Bluetooth beacons installed per floor and zone provide 1–3 m indoor accuracy. The app ranks beacons by signal strength (RSSI) to pinpoint the exact zone.
3. GPS fallback — used outdoors or when BLE is unavailable. Accurate to ~5–10 m.
