TCKRTUIYO - Rainfall Station RTU Web Interface

What This Is

A modern web-based interface for a Base Station/Real-Time Unit (RTU) rainfall monitoring system, designed for a 7" capacitive touchscreen display (1024x600). The system monitors and logs rainfall and related sensors, transmits data to a server, and provides both a kiosk-mode local display and a full HD remote interface.

Core Value

Real-time rainfall and environmental sensor monitoring with automatic data transmission to myvscada server.

Requirements

Validated

(None yet — ship to validate)

Active

Modern web UI for 7" touchscreen (1024x600)
Dashboard with rainfall readings (Today, Hourly, MAR Acc, Yearly Acc)
Solar/Battery voltage monitoring display
Communication status indicator
Settings/Calibration menus
Flash memory file management
CSV data transmission to server

Out of Scope

[Mobile app] — Web-first approach
[Real-time chat] — Not relevant to monitoring use case
[Third-party cloud integration] — Direct server connection only

Context

Target Hardware:

Raspberry Pi Zero 2 W (primary)
Raspberry Pi 3B (alternative)
7-inch capacitive touchscreen 1024x600

Software Stack:

HTML/CSS/JavaScript web UI
Chromium Kiosk Mode for local display
Python backend for sensor communication
Network protocols: FTP, SCP, SFTP, WebDAV

Existing System:

Current RTU runs on embedded system with 4-inch display
Monitors rainfall sensors (RF1, RF2), water level, solar/battery voltage
Data logged to CSV files
Periodic transmission to myvscada server

Constraints

Performance: Must run smoothly on Pi Zero 2 W (low-powered)
Display: Fixed 1024x600 resolution for local kiosk
Remote Access: Full HD interface on PC via separate port (9090)
Dependencies: Minimal (for maintainability on embedded device)

Key Decisions

Decision	Rationale	Outcome
Web-based UI	Cross-platform, no native app development	— Pending
Chromium Kiosk Mode	Reliable on Raspberry Pi, full-screen	— Pending
Python backend	Good sensor integration, CSV handling	— Pending
Kiosk (8080) vs Remote (9090) ports	Separate interfaces for local/remote	— Pending
