SL Transport Departures Display

A modern digital signage system for displaying real-time transit departures and weather information. Perfect for Raspberry Pi-based information displays, kiosks, and public transport information boards.

Note

: Screenshots should be added to the screenshots/ directory. The application displays real-time transit departures in a modern, optimized layout.

Quick Start

Prerequisites

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

Installation

1. Clone the repository

   git clone http://192.168.68.53:3000/kyle/SignageHTML.git
   cd SignageHTML
   

2. Install dependencies

   npm install
   

3. Configure environment variables

   Create a .env file in the root directory (or copy from .env.example if it exists):

   PORT=3002
   OPENWEATHERMAP_API_KEY=your_openweathermap_api_key_here
   DEFAULT_LATITUDE=59.3293
   DEFAULT_LONGITUDE=18.0686
   DEFAULT_LOCATION_NAME=Stockholm
   

   Get your OpenWeatherMap API key from openweathermap.org.

4. Start the server

   npm start
   # or for development with auto-reload:
   npm run dev
   

5. Open in browser Navigate to: http://localhost:3002

The server will start on port 3002 by default (or the port specified in .env). The application will automatically load and begin fetching transit and weather data.

Configuration

Adding Transit Stops

Method 1: Search by Name

1. Click the gear icon (⚙️) in the top-right corner
2. Go to the "Content" tab
3. Enter a stop name in the search box (e.g., "Ambassaderna")
4. Click "Search" and select from results

Method 2: Select from Map

1. Click "Select from Map" button
2. Navigate to your location on the map
3. Click on any transit stop marker
4. Click "Select This Stop" in the popup

Method 3: Manual Entry

1. Click "Add Site Manually"
2. Enter the Site Name and Site ID
3. Enable/disable the site as needed

Environment Variables

The application uses environment variables for configuration. Create a .env file in the root directory:

# Server port (default: 3002)
PORT=3002

# OpenWeatherMap API key (required for weather features)
OPENWEATHERMAP_API_KEY=your_api_key_here

# Default location coordinates (Stockholm, Sweden)
DEFAULT_LATITUDE=59.3293
DEFAULT_LONGITUDE=18.0686
DEFAULT_LOCATION_NAME=Stockholm

Note: The OpenWeatherMap API key is injected into the HTML at runtime by the server. You can also configure the weather location through the settings panel in the UI.

Screen Orientation

The system supports multiple orientations:

• Normal (0°): Standard portrait/landscape
• Vertical (90°): Rotated 90° clockwise
• Upside Down (180°): Rotated 180°
• Vertical Reverse (270°): Rotated 270°
• Landscape (2-column): Optimized landscape layout

Select your orientation from the settings panel (⚙️ → Display → Screen Orientation).

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

Setup Instructions

# Clone the repository
git clone http://192.168.68.53:3000/kyle/SignageHTML.git
cd SignageHTML

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

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

# Reboot to apply all changes
sudo reboot

After reboot, the display will automatically start in kiosk mode.

Architecture

The system consists of the following components:

1. Node.js Server (server.js)

   • Handles API proxying (SL Transport API, OpenWeatherMap)
   • Serves static files from public/ directory
   • Manages site configuration
   • Route handlers organized in server/routes/:
     • departures.js - Transit departure data endpoints
     • sites.js - Site search and nearby sites
     • config.js - Configuration management endpoints

2. Configuration Manager (public/js/components/ConfigManager.js)

   • Manages system settings and UI customization
   • Handles site selection and map integration
   • Persists settings to localStorage

3. Weather Component (public/js/components/WeatherManager.js)

   • Displays weather data from OpenWeatherMap
   • Manages dark mode based on sunrise/sunset
   • Shows hourly forecasts

4. Clock Component (public/js/components/Clock.js)

   • Shows current time and date
   • Swedish locale formatting
   • Updates every second

5. Departures Component (public/js/components/DeparturesManager.js)

   • Fetches and displays transit departure information
   • Groups departures by line number
   • Handles direction indicators and timing

6. Utilities (public/js/utils/)

   • constants.js - Application constants and configuration
   • logger.js - Centralized logging utility

7. Main UI (index.html)

   • Responsive layout with multiple orientation support
   • CSS Grid-based landscape optimization
   • Modern styling with animations
   • External CSS in public/css/:
     • main.css - Base styles, dark mode, orientation styles
     • components.css - Component-specific styles

API Integration

SL Transport API

The system uses the SL Transport API to fetch real-time departure information:

• Endpoint: https://transport.integration.sl.se/v1/sites/{siteId}/departures
• Returns: Real-time departure data with expected times, directions, and line information

OpenWeatherMap API

Weather data is fetched from OpenWeatherMap:

• Requires API key (configured in weather.js)
• Provides current conditions and hourly forecasts
• Used for dark mode timing calculations

For detailed API response documentation, see docs/API_RESPONSE_DOCUMENTATION.md.

UI Settings

The gear icon (⚙️) in the top-right corner opens the settings panel with tabs for:

Display

• Screen orientation selection
• Dark mode settings (Automatic/Sunset-Sunrise, Always On, Always Off)

Appearance

• Background image URL or local file upload
• Background opacity slider

Content

• Transit site management
  • Search for stops by name
  • Select from interactive map
  • Add manually
  • Enable/disable sites
• Option to combine departures going in the same direction

Options

• Additional system preferences

Settings are automatically saved to localStorage and persist across sessions.

Troubleshooting

Common Issues

1. Server won't start

   • Check if port 3002 is already in use: netstat -ano | findstr :3002
   • Ensure Node.js is installed correctly: node --version
   • Check server logs for error messages

2. No departures displayed

   • Verify internet connection
   • Check server console for API errors
   • Ensure site IDs are correct and enabled
   • Verify sites are configured in settings

3. Weather data not loading

   • Check OpenWeatherMap API key in .env file
   • Ensure .env file exists in the root directory
   • Verify the API key is correctly set: OPENWEATHERMAP_API_KEY=your_key_here
   • Restart the server after changing .env file
   • Verify internet connection
   • Look for errors in browser console (F12)
   • Check API key quota/limits on openweathermap.org

4. Map not loading

   • Ensure internet connection is active
   • Check browser console for Leaflet.js errors
   • Verify OpenStreetMap tile access

5. Layout issues

   • Clear browser cache and refresh (Ctrl+F5)
   • Check browser console for CSS errors
   • Verify screen orientation setting matches physical setup
