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)

  • DASH-01: Display rainfall readings (Today, Hourly, MAR, Yearly)
  • DASH-02: Display solar voltage
  • DASH-03: Display battery voltage with status indicator (HIGH/NORMAL/LOW)
  • DASH-04: Display current date and time (HH:MM:SS DD-MM-YYYY)
  • DASH-05: Display station ID
  • DASH-06: Display communication status (signal strength, connection)
  • DASH-07: Display software version
  • DASH-08: Real-time updates via Socket.IO (1-second interval)
  • DASH-09: Last updated timestamp indicator

User Interface (UI-01 through UI-03)

  • UI-01: Touch-optimized interface for 7" 1024x600 display
  • UI-02: Large touch targets (minimum 48px, primary 64px)
  • UI-03: Main menu navigation (Dashboard, Settings, Calibration)

Settings (SETT-01 through SETT-08)

  • SETT-01: Station Info display and edit
  • SETT-02: Date/Time setting (timezone, NTP)
  • SETT-03: Mobile network settings view/edit
  • SETT-04: ADC channel configuration (4 channels, types: 4-20mA, 0-10vDC)
  • SETT-05: Rainfall sensor settings (ID, thresholds)
  • SETT-06: Water level threshold settings
  • SETT-07: EVAP settings
  • SETT-08: Network settings (IP, subnet, gateway, DNS, MAC)

Calibration (CAL-01 through CAL-04)

  • CAL-01: View live ADC readings (4 channels)
  • CAL-02: View current sensor readings with units
  • CAL-03: Reset rainfall counters
  • CAL-04: Display channel type, ADC value, datum, reading

Backend (BACK-01 through BACK-03)

  • BACK-01: Flask backend running on port 8080
  • BACK-02: Sensor data API endpoints (/api/sensors, /api/status)
  • 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

  • src/app.py exists and runs on port 8080
  • /api/status returns valid JSON
  • /api/sensors returns rainfall and voltage data
  • /api/settings supports GET/POST
  • /api/calibration returns ADC data
  • Dashboard renders with touch-optimized UI
  • Settings page allows configuration changes
  • Calibration page shows live readings and reset button
  • Socket.IO connects and pushes updates
  • All 27 Phase 1 requirements implemented
