* fix(errors): stop affected_plugins growing without bound Each repeat of an error pattern appended every plugin in the time window to the pattern's list again, so a plugin failing in a loop grew the display process's memory without limit: 3,000 errors from three plugins reached 2.5 million entries. Keep the list unique. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(fonts): load a BDF font at its native size instead of PIL's default FreeType rejects any size but a BDF strike's own, and FontManager answered that with ImageFont.load_default() -- a different typeface -- so 5x7.bdf requested at 8 or 10px rendered as PIL's default font. Retry at the native strike, as element_style already does. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(web): plugin toggle failures no longer claim "operation in progress" Every exception in POST /plugins/toggle was mapped to PLUGIN_OPERATION_CONFLICT, so any failure told the user "A plugin operation is already in progress". Report the failure as what it is, and record the plugin id in the operation history for form posts too (it read a `data` variable that only the JSON path set). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(web): route plugin card clicks through handlePluginAction The document-level delegation checked `typeof handlePluginAction`, which is scoped inside the plugin-manager IIFE and so never visible to it. Every card click took a copied fallback that stopped propagation (the grid's own listener never ran), confirmed an uninstall twice, and sent Starlark app uninstalls to POST /plugins/uninstall instead of DELETE /starlark/apps/<id>. Expose the handler on window and delegate to it. Also run every test/js/unit suite under pytest: they need only node, but CI ran one of the eight. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(display): apply Rotation durations, WiFi messages and Vegas settings Three settings the web UI saves never reached the display: - Rotation & Durations: display.display_durations was never read. Every plugin inherits get_display_duration() and the plugin was asked first. A saved value now wins. The page shows unsaved screens blank with the plugin's own duration as a placeholder, and saving a blank removes the override, so one save no longer pins every screen. - WiFi status overlay: the controller looked for wifi_status.json one directory above the repo. Both sides now use wifi_manager.get_wifi_status_path(). The message is written by rename so the display never reads it half-written, and the resumed plugin redraws the whole panel afterwards. - Vegas: nothing called coordinator.update_config(), so saved Vegas settings never reached a running scroll. They are now queued when display.vegas_scroll changes, and applied while Vegas is stopped too, so a disable then re-enable works. The follower's scroll-speed default (75) now matches VegasModeConfig's (50). Also throttles Vegas's per-frame live-priority scan to 4Hz. It cost 139us per frame on a Pi 4 with two scoreboards (1.7% of a 125fps frame) and grows with each plugin. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix: keep affected_plugins order when serialized; guard non-Element targets ErrorPattern.to_dict() ran the now-ordered list through set(), so get_error_summary() listed plugins in an unstable order. The document-level card-action listener called event.target.closest() without checking the target is an Element.

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/config_secrets.json- API keys and secrets
API Documentation
The V3 API is the api_v3 blueprint, registered at /api/v3/ in
app.py. 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 configurationPOST /api/v3/config/main- Save main configurationGET /api/v3/config/secrets- Get secrets configurationPOST /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 statusPOST /api/v3/system/action- Control display (action body:start_display,stop_display,restart_display_service,restart_web_service,git_pull,reboot_system,shutdown_system,enable_autostart,disable_autostart)GET /api/v3/display/current- Current display frameGET /api/v3/display/on-demand/status- On-demand statusPOST /api/v3/display/on-demand/start- Trigger on-demand displayPOST /api/v3/display/on-demand/stop- Clear on-demand
Plugins
GET /api/v3/plugins/installed- List installed pluginsGET /api/v3/plugins/config?plugin_id=<id>- Get plugin configPOST /api/v3/plugins/config- Update plugin configurationGET /api/v3/plugins/schema?plugin_id=<id>- Get plugin schemaPOST /api/v3/plugins/toggle- Enable/disable pluginPOST /api/v3/plugins/install- Install from registryPOST /api/v3/plugins/install-from-url- Install from GitHub URLPOST /api/v3/plugins/uninstall- Uninstall pluginPOST /api/v3/plugins/update- Update plugin
Plugin Store
GET /api/v3/plugins/store/list- List available registry pluginsGET /api/v3/plugins/store/github-status- GitHub authentication statusPOST /api/v3/plugins/store/refresh- Refresh registry from GitHub
Real-time Streams (SSE)
SSE stream endpoints are defined directly on the Flask app in app.py
(stream_stats, stream_display, stream_logs, followed by their CSRF
exemption and rate-limit hookup), not on the api_v3 blueprint:
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
