* feat(web): weekly automatic updates with health check and rollback A General-tab toggle (off by default) checks for and installs LEDMatrix and plugin updates once a week, overnight in the configured timezone. - Pre-update checks skip (and report) instead of forcing: local edits or commits, merge/live rebase, no upstream, low disk, missing health check, or a version that was already rolled back. An abandoned rebase (HEAD back on a branch) is cleared, since it would otherwise block every pull. - The pull reuses the Update Code path (now perform_core_update(), which reports dependency install failures as data). - ledmatrix-update-verify.service, started via a .path unit from a request file, restarts the services from its own cgroup, requires them to come up and stay up, and otherwise resets to the previous commit and reinstalls the previous requirements. It runs a copy of the checker taken before the pull. - No SSH needed: switching the toggle on restarts the display service, which (as root) installs the two units from the repo templates for the web user. first_time_install.sh installs them too and takes --enable-auto-update / LEDMATRIX_AUTO_UPDATE (passed through by one-shot-install.sh). - Plugins update after the code passes its check; failures, blocks and rollbacks raise an Overview banner and show under the toggle. Tested end to end on a Pi: web-UI setup, a good update, a broken web service and a broken display (both rolled back), a blocked local edit, and an abandoned rebase found on the device.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(auto-update): CI failures on Linux - Keep the setup result when chown fails. CI runs as a non-root user, where chown to the web user raises; that discarded the result file, so the General tab would never learn whether setup worked. Regression test added. - Register the two new /api/v3/system/auto-update routes in the URL map snapshot. - Use utility classes app.css defines (space-y-1, hover:text-red-600). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(auto-update): address review feedback - Health check: a failed restart command no longer lets the check run against the still-running old process; it counts as a failure (and after a rollback, as a failed rollback). An unreadable restart count is never treated as stable, since a crash loop looks healthy between attempts. - Installer writes the auto_update setting to a temp file and swaps it in, keeping mode and owner, so a running config watcher never reads a truncated config.json. - Verify unit quotes its command-line paths (install folders with spaces); setup refuses folder names systemd would reinterpret (%, quotes, backslashes, control characters) and says so on the General tab. - The auto-update status route no longer returns exception text. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(auto-update): keep error detail in the status route's 500 test_web_error_detail requires every 5xx handler to log the traceback and return describe_exception(e), which redacts credentials, so failures are diagnosable from the web UI. Dropping it for CodeQL broke that policy. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(auto-update): dismiss route rejects non-object JSON with 400 A JSON array or scalar body made `.get('alert_id')` raise, returning 500. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(auto-update): let the app-wide handler answer status-route errors CodeQL (py/stack-trace-exposure, #709) flagged the route's own except, which returned describe_exception(e). web_interface/app.py's error handler already logs the traceback and returns the same redacted detail for any unhandled exception, so the local copy is removed: same response, no new exception-to-response flow, and test_web_error_detail's policy still holds.

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
