* fix(install): add --prefer-binary to pip installs to avoid /tmp exhaustion timezonefinder (~54 MB) includes large timezone polygon data files that pip unpacks into /tmp during installation. On Raspberry Pi, the default tmpfs /tmp size (often ~half of RAM) can be too small, causing the install to fail with an out-of-space error. Adding --prefer-binary tells pip to prefer pre-built binary wheels over source distributions. Since timezonefinder and most other packages publish wheels on PyPI (and piwheels.org has ARM wheels), this avoids the large temporary /tmp extraction and speeds up installs generally.

America/New_York correctly handles DST transitions. The ESPN scoreboard API anchors its schedule calendar to Eastern US time, so this Eastern timezone is intentionally kept for the API date — it is not user-configurable. Game time display is converted separately to the user's configured timezone.

LED Matrix Web Interface V3
Modern, production web interface for controlling the LED Matrix display.
Overview
This directory contains the active V3 web interface with the following features:
- Real-time display preview via Server-Sent Events (SSE)
- Plugin management and configuration
- System monitoring and logs
- Modern, responsive UI
- RESTful API

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 configurationconfig/secrets.json- API keys and secrets
API Documentation
The V3 API is available at /api/v3/ with the following endpoints:
Configuration
GET /api/v3/config/main- Get main configurationPOST /api/v3/config/main- Save main configurationGET /api/v3/config/secrets- Get secrets configurationPOST /api/v3/config/secrets- Save secrets configuration
Display Control
POST /api/v3/display/start- Start display servicePOST /api/v3/display/stop- Stop display servicePOST /api/v3/display/restart- Restart display serviceGET /api/v3/display/status- Get display service status
Plugins
GET /api/v3/plugins- List installed pluginsGET /api/v3/plugins/<id>- Get plugin detailsPOST /api/v3/plugins/<id>/config- Update plugin configurationGET /api/v3/plugins/<id>/enable- Enable pluginGET /api/v3/plugins/<id>/disable- Disable plugin
Plugin Store
GET /api/v3/store/plugins- List available pluginsPOST /api/v3/store/install/<id>- Install pluginPOST /api/v3/store/uninstall/<id>- Uninstall pluginPOST /api/v3/store/update/<id>- Update plugin
Real-time Streams (SSE)
GET /api/v3/stream/stats- System statistics streamGET /api/v3/stream/display- Display preview streamGET /api/v3/stream/logs- Service logs stream
Development
When making changes to the web interface:
- Edit files in this directory
- Test changes by running
python3 web_interface/start.py - 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
