* fix: install plugin dependencies through root-visible installer in Plugin Store install_plugin/update_plugin (store_manager.py) installed requirements.txt with a bare `pip3` off PATH, bypassing the root-visible installer added in #380 for the "Reinstall Plugin Deps" button. Two bugs stacked: (1) `pip3` can resolve to a different Python install than the one that actually runs ledmatrix.service, and (2) even when it resolves correctly, ledmatrix-web runs as a non-root user so the package lands in that user's local site-packages, invisible to root-run ledmatrix.service. Either way the install reports success and writes the .dependencies_installed hash marker, so plugin_loader's own (correct) install-on-load path skips reinstalling — leaving the dependency permanently missing until a user finds and clicks the separate "Reinstall Plugin Deps" tool. This is why users kept hitting "No module named 'astral'" for the weather plugin even after installing it from the Store. Extracts the sudo-wrapper-then-fallback install logic from api_v3.py's _pip_install_requirements into src/common/permission_utils.py as install_requirements_file, and routes store_manager.py's dependency installation through it so the automatic Store install/update path now matches the manual "Reinstall Plugin Deps" path.

Both calls use list-form argv (no shell=True, so no shell-injection surface), and the only dynamic value is req_file, a Path built internally by callers rather than raw external input; safe_pip_install.sh independently re-validates it before installing anything as root. Suppresses with inline `# nosec B603` comments matching this codebase's existing convention (see permission_utils.py's own PROTECTED_SYSTEM_DIRECTORIES, display_manager.py, sync_manager.py, etc.).

Upgrading it via plain `pip install` aborts with "uninstall-no-record-file" because pip refuses to uninstall a package it has no record of, in place — which is exactly the "Some web interface dependencies failed to install" warning first-time install hits. scripts/install_dependencies_apt.py and scripts/fix_perms/safe_pip_install.sh already work around this with --ignore-installed (lets pip lay the new version down in /usr/local, shadowing the apt copy, instead of trying to remove it first). first_time_install.sh's own direct pip invocations — the per-package requirements.txt loop, the web_interface/requirements.txt install, and the requirements_web_v2.txt fallback — didn't have it. Adds --ignore-installed to all three so first-time install no longer fails on this well-known apt/pip conflict.

Without it, the same apt/pip RECORD-file conflict this PR fixes elsewhere (first_time_install.sh, install_dependencies_apt.py) could still hit installs that fall back to this path (e.g. a plugin's requirements.txt on a host where safe_pip_install.sh isn't set up yet).

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
