web_interface/blueprints/api_v3.py held 111 routes, 56 helpers and 181 functions in one module -- 9% of the core by line count and three times the next largest file. It becomes a package of nine route modules grouped by path segment, plus __init__.py for the shared imports, constants, Blueprint and helpers. Every route module decorates the SAME api_v3 Blueprint object, so endpoint names stay api_v3.<function>, the URL map is unchanged and app.py is untouched. Verified: 111 routes before, 111 after, byte-identical rules, endpoints and methods, and every endpoint still on the one blueprint. plugins 3,867 config 1,178 starlark 692 system 619 fonts 452 misc 398 wifi 361 display 326 backup 212 __init__ 1,787 (imports, constants, Blueprint, 56 helpers) Two things the URL-map check could not catch, both found by running the suite: 1. PROJECT_ROOT = Path(__file__).parent.parent.parent. Moving the code one directory deeper made that resolve to web_interface/ instead of the project root. Nothing failed at import; it surfaced as ~110 tests failing with 404s and "installation script not found", because every path built from it was one level too shallow. Now parents[3], and test_api_v3_url_map.py asserts PROJECT_ROOT/run.py exists so the next move cannot repeat it. 2. Module-attribute patching. Tests do monkeypatch.setattr(api_v3_module, "_BACKUP_EXPORT_DIR", ...) and a route module that binds such a name by value never sees the patch. The shared code therefore stays in __init__.py rather than moving to a _common submodule -- it has to live on the module the tests patch -- and the eleven names tests patch are read back through the package (_pkg.X) instead of bound by value. Those eleven were found by AST-scanning every setattr in the test tree, not by guessing; "time" is among them, used to drive a fake clock through the second-resolution credential-backup filenames. Test changes are confined to what genuinely moved: patch targets that now name the owning route module, imports of helpers, and six tests that scan the api_v3 source as a file and now read the package directory. Full suite: 4,278 passed, 68 skipped, 0 failed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014RRtqXDCnvnY6EQwhT5CV9
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
