Reviewed all 12 CodeRabbit comments on PR #306, verified each against the current code, and fixed the 11 valid ones. The 12th finding is a real code bug (cache_manager.delete() calls in api_helper.py and resource_monitor.py) that's already in the planned follow-up code-fix PR, so it stays out of this docs PR. Fixed: .cursor/plugins_guide.md, .cursor/README.md, .cursorrules - I claimed "there is no --emulator flag" in 3 places. Verified in run.py:19-20 that the -e/--emulator flag is defined and functional (it sets os.environ["EMULATOR"]="true" before the display imports). Other docs I didn't touch (.cursor/plugin_templates/QUICK_START.md, docs/PLUGIN_DEVELOPMENT_GUIDE.md) already use the flag correctly. Replaced all 3 wrong statements with accurate guidance that both forms work and explains the CLI flag's relationship to the env var. .cursorrules, docs/GETTING_STARTED.md, docs/WEB_INTERFACE_GUIDE.md, docs/PLUGIN_DEVELOPMENT_GUIDE.md - Four places claimed "the plugin loader also falls back to plugins/". Verified that PluginManager.discover_plugins() (src/plugin_system/plugin_manager.py:154) only scans the configured directory — no fallback. The fallback to plugins/ exists only in two narrower places: store_manager.py:1700-1718 (store install/update/uninstall operations) and schema_manager.py:70-80 (schema lookup for the web UI form generator). Rewrote all four mentions with the precise scope. Added a recommendation to set plugin_system.plugins_directory to "plugins" for the smoothest dev workflow with dev_plugin_setup.sh symlinks. docs/FONT_MANAGER.md - The "Status" warning told plugin authors to use display_manager.font_manager.resolve_font(...) as a workaround for loading plugin fonts. Verified in src/font_manager.py that resolve_font() takes a family name, not a file path — so the workaround as written doesn't actually work. Rewrote to tell authors to load the font directly with PIL or freetype-py in their plugin. - The same section said "the user-facing font override system in the Fonts tab still works for any element that's been registered via register_manager_font()". Verified in web_interface/blueprints/api_v3.py:5404-5428 that /api/v3/fonts/overrides is a placeholder implementation that returns empty arrays and contains "would integrate with the actual font system" comments — the Fonts tab does not have functional integration with register_manager_font() or the override system. Removed the false claim and added an explicit note that the tab is a placeholder. docs/ADVANCED_FEATURES.md:523 - The on-demand section said REST/UI calls write a request "into the cache manager (display_on_demand_config key)". Wrong — verified via grep that api_v3.py:1622 and :1687 write to display_on_demand_request, and display_on_demand_config is only written by the controller during activation (display_controller.py:1195, cleared at :1221). Corrected the key name and added controller file:line references so future readers can verify. docs/ADVANCED_FEATURES.md:803 - "Plugins using the background service" paragraph listed all scoreboard plugins but an orphaned "⏳ MLB (baseball)" bullet remained below from the old version of the section. Removed the orphan and added "baseball/MLB" to the inline list for clarity. web_interface/README.md - The POST /api/v3/system/action action list was incomplete. Verified in web_interface/app.py:1383,1386 that enable_autostart and disable_autostart are valid actions. Added both. - The Plugin Store section was missing GET /api/v3/plugins/store/github-status (verified at api_v3.py:3296). Added it. - The SSE line-range reference was app.py:607-615 but line 619 contains the "Exempt SSE streams from CSRF and add rate limiting" block that's semantically part of the same feature. Extended the range to 607-619. docs/GETTING_STARTED.md - Rows/Columns step said "Columns: 64 or 96 (match your hardware)". The web UI's validation accepts any integer in 16-128. Clarified that 64 and 96 are the common bundled-hardware values but the valid range is wider. Not addressed (out of scope for docs PR): - .cursorrules:184 CodeRabbit comment flagged the non-existent cache_manager.delete() calls in src/common/api_helper.py:287 and src/plugin_system/resource_monitor.py:343. These are real CODE bugs, not doc bugs, and they're the first item in the planned post-docs-refresh code-cleanup PR (see /home/chuck/.claude/plans/warm-imagining-river.md). The docs in this PR correctly state that delete() doesn't exist on CacheManager — the fix belongs in the follow-up code PR that either adds a delete() shim or updates the two callers.

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 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 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
(app.py:607-619 — includes the CSRF exemption and rate-limit hookup
alongside the three route definitions), 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
