SL Transport Departures Display

A digital signage system for displaying transit departures and weather information. Perfect for Raspberry Pi-based information displays.

Features

• Real-time transit departure information
• Current weather and hourly forecast
• Multiple screen orientation support (0°, 90°, 180°, 270°)
• Dark mode with automatic switching based on sunrise/sunset
• Custom background image support
• Responsive design for various screen sizes

Quick Start

1. Clone this repository
2. Run the server: node server.js
3. Open a browser and navigate to: http://localhost:3002

System Requirements

• Node.js (v12 or higher)
• Modern web browser with CSS3 support
• Internet connection for API access

Raspberry Pi Setup

For a dedicated display on Raspberry Pi, we've included a setup script that:

1. Installs Node.js if needed
2. Creates a systemd service to run the server on boot
3. Sets up Chromium to launch in kiosk mode on startup
4. Disables screen blanking and screensaver
5. Creates a desktop shortcut for manual launch

To set up on Raspberry Pi:

# Clone the repository
git clone https://github.com/yourusername/sl-departures-display.git
cd sl-departures-display

# Make the setup script executable
chmod +x raspberry-pi-setup.sh

# Run the setup script as root
sudo ./raspberry-pi-setup.sh

# Reboot to apply all changes
sudo reboot

Configuration

Changing Transit Stop

To display departures for a different transit stop, modify the API_URL in server.js:

const API_URL = 'https://transport.integration.sl.se/v1/sites/YOUR_SITE_ID/departures';

Changing Weather Location

To display weather for a different location, modify the latitude and longitude in index.html:

window.weatherManager = new WeatherManager({
    latitude: YOUR_LATITUDE,
    longitude: YOUR_LONGITUDE
});

UI Settings

The gear icon in the top-right corner opens the settings panel where you can configure:

• Screen orientation
• Dark mode (auto/on/off)
• Background image and opacity
• Transit sites

Settings are saved to localStorage and persist across sessions.

Architecture

The system consists of the following components:

1. Node.js Server - Handles API proxying and serves static files
2. Configuration Manager - Manages system settings and UI customization
3. Weather Component - Displays weather data and manages dark mode
4. Clock Component - Shows current time and date
5. Departures Component - Displays transit departure information
6. Main UI - Responsive layout with multiple orientation support

Troubleshooting

Common Issues:

1. Server won't start

   • Check if port 3002 is already in use
   • Ensure Node.js is installed correctly

2. No departures displayed

   • Verify internet connection
   • Check server console for API errors
   • Ensure the site ID is correct (currently set to 9636)

3. Weather data not loading

   • Check OpenWeatherMap API key
   • Verify internet connection
   • Look for errors in browser console
