+# 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
