* Add system diagnostics, power controls, and WiFi radio toggle to Tools tab Expands the web UI Tools tab with safe, purpose-built controls so users can manage the Pi without SSHing in, instead of an arbitrary-command terminal (the web UI has no auth and CSRF is disabled, so a shell would be unsafe). - System Diagnostics card: renders the existing but previously-unused GET /api/v3/system/status endpoint (CPU, memory, temp, disk, uptime), with a manual refresh and a 10s poll. - System Power section: reboot/shutdown buttons wired to the existing reboot_system / shutdown_system actions, behind a confirm step, with a dedicated powerAction() helper that treats the dropped connection as the expected "going offline" outcome rather than an error. - Network Radio section: WiFi on/off toggle backed by new GET/POST /api/v3/wifi/radio endpoints and WiFiManager.set_wifi_radio() / get_wifi_radio_state(). Disabling WiFi is refused unless a wired connection is present (reusing the existing lockout guards), with an explicit force-off confirmation for advanced users. No new privileged commands: uses nmcli radio wifi on|off (already sudo-allowlisted) and the existing reboot/poweroff grants, so the sudoers-alignment guard test stays green. Bluetooth toggle intentionally omitted since the installer removes the BlueZ stack for LED timing.

A plain bool() cast turned {"enabled":"false"} into True (enabling instead of disabling) for any non-UI API caller. - wifi_manager.set_wifi_radio() now returns a reason code alongside (success, message); the /wifi/radio error response includes it. The Tools UI only shows the force-off confirmation when reason == 'no_ethernet', so a genuine nmcli failure surfaces its real error instead of a misleading "no wired connection" prompt that would just retry into the same failure. - tools.html: gate the 10s diagnostics poll on panel visibility (document.hidden / offsetParent), so switching to another tab stops the recurring /api/v3/system/status calls instead of churning the Pi off-screen. The initial load and manual Refresh remain unconditional. Verified: {"enabled":"false"} now disables (refused w/ reason:no_ethernet), {"enabled":"true"} enables; inline JS passes node --check; py_compile clean.

Narrow it to (OSError, subprocess.SubprocessError) — the errors subprocess.run realistically raises — and log with exc_info=True for full context on the Pi. Anything genuinely unexpected now propagates to the endpoint's outer handler (500), matching the codebase's specific-exception convention.

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
