Note

This project is in active development. Windows is fully supported; Linux X11 is partial, macOS/Wayland are WIP.

✨ Features

Feature	Description
🖥️ Monitor Sync	Sample colors from screen regions and sync to your LED strip in real-time
🎵 Music Sync	React to audio with dynamic color patterns
🎨 Color Control	Set custom colors and brightness directly from the app
🖌️ Modern GUI	Blue-accented PySide6 interface with selectable Acrylic, Mica, and Solid Dark window materials
🔌 Multi-Vendor	Govee (LAN), iDotMatrix pixel panels (Bluetooth), and LSC/Tuya WiFi lights
🔍 Auto-Discovery	Automatically finds Govee devices on your LAN via UDP broadcast
⚡ Low Latency	Direct LAN communication, no cloud required

Supported devices

Every device family works out of the box — a single pip install lumisync (or the packaged Windows build) bundles all transports, no extras to remember.

Family	Transport	Notes
Govee strips/bulbs	LAN (UDP)	Enable "LAN Control" in the Govee app
iDotMatrix panels	Bluetooth LE	Pixel displays; see docs
LSC / Tuya WiFi lights	LAN (Tuya local)	Needs the device's local key — see docs

📸 Screenshots

Devices

_{Discover, organize, and directly control LAN and Bluetooth lights.}

Monitor and music sync

Monitor Sync Map display colors across one or more lights.	Music Sync Choose reactions and palettes or let Auto Director decide.

📦 Installation

Requirements: Python 3.11 or higher

From PyPI (Recommended)

pip install lumisync

From GitHub (Latest)

pip install git+https://github.com/Minlor/LumiSync.git

Development Install

git clone https://github.com/Minlor/LumiSync.git
cd LumiSync
pip install -e .

Prebuilt downloads

• Windows — a portable .zip and a single-file .exe are attached to each GitHub release.
• Linux — an x86_64 AppImage is attached to each release; chmod +x it and run. Build it yourself with tools/build_linux.sh (needs Python 3.12+ and appimagetool deps). A Flatpak is scaffolded in packaging/flatpak/ but not yet finished.

Platform notes: Windows is fully supported. On Linux, device control, music sync, and manual control work on X11 and Wayland; screen (monitor) sync currently requires an X11/Xorg session — Wayland capture is planned.

🚀 Usage

Launch the App

lumisync

The GUI opens by default. The legacy interactive terminal is still available with lumisync --cli; direct headless modes are available through lumisync --monitor and lumisync --music.

Quick Start

1. Discover devices — Click "Discover Devices" for Govee LAN lights or "Scan Bluetooth" for pixel panels.
2. Select your lights — Choose one or more devices from the Devices page.
3. Control your lights — Set color, brightness and power directly from each device card.
4. Start syncing — Open Monitor Sync or Music Sync, choose the target devices and start the mode.

Interface

• Devices — Discover, add and control LAN or Bluetooth lights; multi-select devices for bulk actions.
• Monitor Sync — Map display colors to selected devices, groups, zones, and custom LED regions.
• Music Sync — Choose reactions, palettes, targets and brightness, or use Auto Director.
• Draw — Paint still images or frame-by-frame animations for compatible iDotMatrix panels.
• Settings — Choose Acrylic, Mica, or Solid Dark; select a display, tune sync behavior, manage groups, startup and system-tray options.

Configuration

• LED Mapping - Customize which screen regions map to which LEDs
• Brightness - Adjust per-mode brightness (10-100%)
• Display Selection - Choose which monitor to capture (multi-monitor support)
• Sync Tuning - Tune smoothing, saturation, frame rate, gamma and music response

Run Tests

python -m unittest discover -s tests

Brand and documentation assets

The production app icon, transparent mark, tray variants, Windows .ico, and GitHub banner live in assets/brand. Regenerate the complete icon set from its single SVG geometry with:

python tools/generate_brand_assets.py

Fresh README screenshots can be captured from the real PySide application on Windows with:

python tools/capture_readme_screenshots.py --material acrylic

Platform Support
