## Blockers

*No current blockers*

### ~~BT RSSI Acquisition~~ (RESOLVED)
**Problem:** Cannot get reliable RSSI values for Bluetooth devices
- `hcitool rssi <addr>` - Only works for connected devices
- `bluetoothctl info` - No RSSI for cached devices

**Solution:** Switched to `bleak` Python BLE library which provides reliable RSSI via D-Bus/BlueZ.

---

## Notes

- BLE scanning now uses `bleak` Python library (reliable RSSI via D-Bus)
- WiFi scanning works well with `iw` command
- Live BT tracking auto-starts on page load (4-second scan interval)
- Historical data stored in SQLite database with auto-cleanup
- Movement detection uses statistical analysis (5-sample avg + 2σ threshold)
- Floor assignments persist in database across page reloads
- Popups stay open during live tracking updates
- Manual position override: drag floor-assigned device markers to set custom position
- **Peer Sync**: Multiple scanner instances can share device metadata
  - Devices synced from peers retain source scanner info
  - Positions calculated relative to detecting scanner (not local scanner)
  - Peer scanners shown on 3D map as cyan markers
  - Background sync every 30 seconds (configurable)
- **Master Dashboard**: Designated master node can view any peer's data
  - Set `is_master: true` in config.yaml to enable
  - Node selector dropdown appears in header
  - Switch between local/peer views without page redirect
  - Live tracking runs on selected peer node
  - WebSocket connects to peer for real-time updates
- **Node Control API**: Master can start/stop/restart peers via SSH
  - `POST /api/nodes/<id>/start|stop|restart`
  - `GET /api/nodes/<id>/status`
  - Integrated with Home Assistant via rest_command
- **Termux/Android Support**: BT scanning skipped (no D-Bus), location check optional
- **Filter Behavior**: WiFi/BT always scanned; filter controls display only
