Utility Scripts
This directory contains utility scripts for maintenance and system operations.
Scripts
clear_cache.py- Clears LEDMatrix cache data (specific keys or all cache)start_web_conditionally.py- Conditionally starts the web interface based on config settingswifi_monitor_daemon.py- Background daemon that monitors WiFi/Ethernet connection and manages access point modecleanup_venv.sh- Cleans up Python virtual environment filesclear_python_cache.sh- Clears Python cache files (pycache, *.pyc, etc.)
Usage
Clear Cache
python3 scripts/utils/clear_cache.py --list # List cache keys
python3 scripts/utils/clear_cache.py --clear-all # Clear all cache
python3 scripts/utils/clear_cache.py --clear <key> # Clear specific key
Start Web Interface Conditionally
This script is typically called by the systemd service (ledmatrix-web.service) and checks the web_display_autostart setting in config/config.json before starting the web interface.
WiFi Monitor Daemon
This daemon is typically run as a systemd service (ledmatrix-wifi-monitor.service) and automatically manages WiFi access point mode based on network connectivity.
