Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

• Local: http://localhost:5000
• Network: http://:5000

Configuration

The web interface reads configuration from:

• config/config.json - Main configuration
• config/config_secrets.json - API keys and secrets

API Documentation

The V3 API is mounted at /api/v3/ (app.py:144). For the complete list and request/response formats, see docs/REST_API_REFERENCE.md. Quick reference for the most common endpoints:

Configuration

• GET /api/v3/config/main - Get main configuration
• POST /api/v3/config/main - Save main configuration
• GET /api/v3/config/secrets - Get secrets configuration
• POST /api/v3/config/raw/main - Save raw main config (Config Editor)
• POST /api/v3/config/raw/secrets - Save raw secrets

Display & System Control

• GET /api/v3/system/status - System status
• POST /api/v3/system/action - Control display (action body: start_display, stop_display, restart_display_service, restart_web_service, git_pull, reboot_system, shutdown_system)
• GET /api/v3/display/current - Current display frame
• GET /api/v3/display/on-demand/status - On-demand status
• POST /api/v3/display/on-demand/start - Trigger on-demand display
• POST /api/v3/display/on-demand/stop - Clear on-demand

Plugins

• GET /api/v3/plugins/installed - List installed plugins
• GET /api/v3/plugins/config?plugin_id=<id> - Get plugin config
• POST /api/v3/plugins/config - Update plugin configuration
• GET /api/v3/plugins/schema?plugin_id=<id> - Get plugin schema
• POST /api/v3/plugins/toggle - Enable/disable plugin
• POST /api/v3/plugins/install - Install from registry
• POST /api/v3/plugins/install-from-url - Install from GitHub URL
• POST /api/v3/plugins/uninstall - Uninstall plugin
• POST /api/v3/plugins/update - Update plugin

Plugin Store

• GET /api/v3/plugins/store/list - List available registry plugins
• POST /api/v3/plugins/store/refresh - Refresh registry from GitHub

Real-time Streams (SSE)

SSE stream endpoints are defined directly on the Flask app (app.py:607-615), not on the api_v3 blueprint:

• GET /api/v3/stream/stats - System statistics stream
• GET /api/v3/stream/display - Display preview stream
• GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

1. Edit files in this directory
2. Test changes by running python3 web_interface/start.py
3. Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

• Templates and static files use the v3/ prefix to allow for future versions
• The interface uses Flask blueprints for modular organization
• SSE streams provide real-time updates without polling
