Major additions across backend, frontend, and infrastructure:
Backend:
- IoT collector framework (Modbus TCP, MQTT, HTTP) with manager
- Realistic Beijing solar/weather simulator with cloud transients
- Alarm auto-checker with demo anomaly injection (3-4 events/hour)
- Report generation (PDF/Excel) with sync fallback and E2E testing
- Energy data CSV/XLSX export endpoint
- WebSocket real-time broadcast at /ws/realtime
- Alembic initial migration for all 14 tables
- 77 pytest tests across 9 API routers
Frontend:
- Live notification badge with alarm count (was hardcoded 0)
- Sankey energy flow diagram on dashboard
- Device photos (SVG illustrations) on all device pages
- Report download with status icons
- Energy data export buttons (CSV/Excel)
- WebSocket hook with auto-reconnect and polling fallback
- BigScreen 2D responsive CSS (tablet/mobile)
- Error handling improvements across pages
Infrastructure:
- PostgreSQL + TimescaleDB as primary database
- Production docker-compose with nginx reverse proxy
- Comprehensive Chinese README
- .env.example with documentation
- quick-start.sh deployment script
- nginx config with gzip, caching, security headers
Data:
- 30-day realistic backfill (47K rows, weather-correlated)
- 18 devices, 6 alarm rules, 15 historical alarm events
- Beijing solar position model with seasonal variation

- New /bigscreen-3d route: React Three Fiber 3D campus with buildings,
PV panels, heat pumps, meters, and sensors — all procedural geometry
- Interactive: hover highlight, click to select, camera fly-in to
device detail views (PV inverter, heat pump, meter, heat meter, sensor)
- Real-time data: 15s polling for overview, 5s for selected device
- Energy flow particles along PV→Building, Grid→Building, Building→HP paths
- HUD overlay with date/clock, bottom metrics bar, device list panel
- New /bigscreen route: 2D dashboard with energy flow diagram, charts
- New /devices route: device management page
- Vite config: optimizeDeps.force for R3F dep consistency
- Data backfill script for testing
