Reported from a pi whose checkout sat on a local branch:
git pull failed (returncode=1): There is no tracking information for
the current branch. Please specify which branch you want to rebase
against.
The Tools tab reported that as "Update failed; check logs for details",
which tells the user nothing they can act on, and the underlying git
message never reached the UI at all.
A branch with no upstream is easy to end up on — checking one out by
name, restoring a backup, or following a guide that names a branch — and
until now it left the update button permanently broken with no way out
except SSH.
resolve_pull_command() now decides how to pull:
- upstream set -> git pull --rebase, as before
- no upstream, origin/<branch> -> git pull --rebase origin <branch>,
then attach tracking so the next update is a plain pull
- no upstream, no remote branch -> an error naming the branch and
pointing at Switch branch
- detached HEAD -> says so, rather than failing obscurely
That resolution happens BEFORE the stash. Previously the handler stashed
local changes and then discovered it could not pull, putting the user's
work away for an update that was never going to run.
Failures now surface git's own message instead of "check logs".
Adds a branch picker to the Tools tab, backed by GET
/system/git-branches (local + remote-only) and a checkout_branch action.
Switching attaches tracking, so Pull Latest works afterwards. Branch
names are validated against a strict pattern before reaching a subprocess
argument list.
Local edits block a checkout, as they should. Rather than a truncated
one-line error, the response carries git's full list of blocking files
and a can_retry_with_stash flag; the UI then offers "Stash and switch" as
an explicit choice. Stashing is never done unasked — putting someone's
edits away without consent is worse than refusing the switch.
Verified on the pi that produced the report: on its untracked 'audit'
branch the update now returns the actionable message, git-info reports
upstream='' and can_pull=false, and an injected branch name is rejected.
27 tests build real git repositories and cover each path, including the
stash route that could not be exercised safely on the device.
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
