Fix (10 of 15 findings): plugin-repos/march-madness/requirements.txt: Add urllib3>=1.26.0 — manager.py directly imports from urllib3; it was an undeclared transitive dependency via requests. scripts/dev/dev_plugin_setup.sh: Restore subshell form (cd "$target_dir" && git pull --rebase) || true so the shell's working directory is not permanently changed after the if-cd block. Previous fix for SC2015 leaked cwd into the remainder of the script. src/base_classes/sports.py: Narrow 'except Exception' to 'except RuntimeError as e' and log via self.logger.debug — Path.home() raises only RuntimeError for service users; other exceptions should not be silently swallowed. src/config_service.py: Fix stale "MD5 checksum" in ConfigVersion.__init__ docstring (line 40); the implementation uses SHA-256 since the Codacy fix. src/wifi_manager.py: Log the last-resort AP enable failure with exc_info=True instead of silently passing — failure here means the device may be unreachable. web_interface/blueprints/pages_v3.py: Log the outer metadata pre-load exception at debug level instead of swallowing it silently; schema still loads fully below. src/background_data_service.py: Remove unused 'timeout' parameter from shutdown() — executor.shutdown() does not accept timeout; update __del__ caller accordingly. src/font_manager.py: Validate URL scheme before urlretrieve — reject non-http/https schemes (e.g. file://) to prevent reading local files from config-supplied URLs. src/plugin_system/plugin_executor.py: Simplify redundant except tuple: (PluginTimeoutError, PluginError, Exception) → Exception, which already covers the others. test/test_display_controller.py: Mark empty test_plugin_discovery_and_loading as @pytest.mark.skip with reason. Move duplicate 'from datetime import datetime' to module header and remove the stray mid-module copy. Skip (5 of 15 findings, with reasons): - pytest 9.0.3 concerns: full suite already verified (467 pass, 18 pre-existing) - Pillow 12.2.0 API concerns: no deprecated APIs in codebase; tests + Pi smoke test pass - diagnose_web_ui.sh sudo validation: set -e already ensures fail-fast on any sudo failure - app.py request-logging except: must stay silent (recursive logging risk); annotated - app.py SSE file-read except: genuinely transient I/O; annotated Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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
