* fix(config): normalize nullable arrays and objects instead of refusing them
`element_style._nullable` widens every `customization.modes.<mode>` override
with 'null' so a blank means "inherit the base", which turns a colour declared
"array" into ["array", "null"]. `normalize_config_values` only knew how to
convert null/integer/number/boolean out of a union, so a valid [0, 249, 0]
matched nothing and logged
Could not normalize field customization.modes.upcoming.odds_text.text_color:
value=[0, 249, 0], type=<class 'list'>, schema_type=['array', 'null']
The warning was the harmless half. It `continue`d past the single-type handling
below, where `prop_type == 'array'` coerces items, so a nullable array never had
its items normalized while a plain one did. A form posts numbers as strings, so
["0", "249", "0"] survived to the validator and was rejected with "Expected type
integer, got str" -- setting a per-mode colour in the web UI failed outright.
Every per-mode override of a structural or string type was exposed, across all
eight scoreboard plugins, not only colours.
Re-enter the single-type handling with the matched member rather than bailing,
accept a string that matches, and warn only on a genuine mismatch so the
diagnostic still reaches the validator.

* fix(config): convert only integral numbers for integer array items
Review catch on the previous commit. Routing nullable arrays into the shared
item handling made its integer coercion reachable for them, and that coercion
called int(v) on any number: a client sending [2.5, 249, 0] for an RGB array
got 2 stored and a 200 back, so a wrong value was silently corrected into a
valid-looking one rather than refused.
Convert only genuinely integral values, at both the union-item and the plain
'array' item branch so the two cannot drift. A whole float -- 2.0, which is all
JSON can express for an integer -- still converts. This also settles an
inconsistency that predates the change: int('2.5') raises, so the string form
was always preserved and rejected while the numeric form was truncated.

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
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 the api_v3 blueprint, registered at /api/v3/ in
app.py. 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 in app.py
(stream_stats, stream_display, stream_logs, followed by their CSRF
exemption and rate-limit hookup), 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
