# Phase 1 Plan: Foundation & Kiosk UI Summary
|
|
|
|
## One-Liner
|
|
|
|
Flask + SocketIO backend with real-time 7" touchscreen dashboard, settings, and calibration UI for rainfall station RTU
|
|
|
|
## Objective Achieved
|
|
|
|
Successfully built the foundational Flask backend with real-time sensor data API and the 7" touchscreen kiosk UI (port 8080) displaying rainfall readings, voltage status, date/time, station ID, communication status, and software version. Included Settings and Calibration menus for configuration access.
|
|
|
|
## Completed Requirements
|
|
|
|
### Dashboard (DASH-01 through DASH-09)
|
|
- [x] DASH-01: Display rainfall readings (Today, Hourly, MAR, Yearly)
|
|
- [x] DASH-02: Display solar voltage
|
|
- [x] DASH-03: Display battery voltage with status indicator (HIGH/NORMAL/LOW)
|
|
- [x] DASH-04: Display current date and time (HH:MM:SS DD-MM-YYYY)
|
|
- [x] DASH-05: Display station ID
|
|
- [x] DASH-06: Display communication status (signal strength, connection)
|
|
- [x] DASH-07: Display software version
|
|
- [x] DASH-08: Real-time updates via Socket.IO (1-second interval)
|
|
- [x] DASH-09: Last updated timestamp indicator
|
|
|
|
### User Interface (UI-01 through UI-03)
|
|
- [x] UI-01: Touch-optimized interface for 7" 1024x600 display
|
|
- [x] UI-02: Large touch targets (minimum 48px, primary 64px)
|
|
- [x] UI-03: Main menu navigation (Dashboard, Settings, Calibration)
|
|
|
|
### Settings (SETT-01 through SETT-08)
|
|
- [x] SETT-01: Station Info display and edit
|
|
- [x] SETT-02: Date/Time setting (timezone, NTP)
|
|
- [x] SETT-03: Mobile network settings view/edit
|
|
- [x] SETT-04: ADC channel configuration (4 channels, types: 4-20mA, 0-10vDC)
|
|
- [x] SETT-05: Rainfall sensor settings (ID, thresholds)
|
|
- [x] SETT-06: Water level threshold settings
|
|
- [x] SETT-07: EVAP settings
|
|
- [x] SETT-08: Network settings (IP, subnet, gateway, DNS, MAC)
|
|
|
|
### Calibration (CAL-01 through CAL-04)
|
|
- [x] CAL-01: View live ADC readings (4 channels)
|
|
- [x] CAL-02: View current sensor readings with units
|
|
- [x] CAL-03: Reset rainfall counters
|
|
- [x] CAL-04: Display channel type, ADC value, datum, reading
|
|
|
|
### Backend (BACK-01 through BACK-03)
|
|
- [x] BACK-01: Flask backend running on port 8080
|
|
- [x] BACK-02: Sensor data API endpoints (/api/sensors, /api/status)
|
|
- [x] BACK-03: Settings API (read/write) (/api/settings)
|
|
|
|
## Implementation Details
|
|
|
|
### Architecture
|
|
- **Web Layer**: Flask templates serving 1024x600 optimized HTML
|
|
- **API Layer**: RESTful endpoints + Socket.IO for real-time push
|
|
- **Service Layer**: SensorService (mock data), ConfigService (JSON persistence)
|
|
|
|
### API Endpoints
|
|
| Endpoint | Method | Description |
|
|
|----------|--------|-------------|
|
|
| /api/status | GET | Station ID, datetime, version, connection |
|
|
| /api/sensors | GET | Rainfall, voltage readings |
|
|
| /api/settings | GET/POST | All configuration |
|
|
| /api/calibration | GET | Live ADC readings |
|
|
| /api/calibration/reset_rainfall | POST | Reset counters |
|
|
|
|
### Real-Time Updates
|
|
- Socket.IO connection established on page load
|
|
- Server emits `sensor_update` event every 1 second
|
|
- Dashboard auto-updates without page refresh
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Auth Gates
|
|
|
|
None encountered.
|
|
|
|
## Notes for Future Phases
|
|
|
|
1. **Phase 2**: Add CSV logging with buffered writes to avoid SD card wear
|
|
2. **Phase 3**: Implement FTP/SFTP transmission to myvscada server
|
|
3. **Phase 4**: Add port 9090 with authentication for remote HD access
|
|
4. **Hardware Integration**: Replace mock sensor data with actual GPIO/ADC reads
|
|
|
|
## Self-Check: PASSED
|
|
|
|
- [x] src/app.py exists and runs on port 8080
|
|
- [x] /api/status returns valid JSON
|
|
- [x] /api/sensors returns rainfall and voltage data
|
|
- [x] /api/settings supports GET/POST
|
|
- [x] /api/calibration returns ADC data
|
|
- [x] Dashboard renders with touch-optimized UI
|
|
- [x] Settings page allows configuration changes
|
|
- [x] Calibration page shows live readings and reset button
|
|
- [x] Socket.IO connects and pushes updates
|
|
- [x] All 27 Phase 1 requirements implemented
