+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for automated CI/CD processes.
+
+## Workflows Overview
+
+### 🔨 `build.yml` - Build Desktop App
+**Triggers:** Push to main/develop, Pull Requests, Releases
+
+**Purpose:** Builds the desktop application for all supported platforms (macOS, Windows, Linux)
+
+**Features:**
+- Cross-platform builds (macOS Universal, Windows x64, Linux x64)
+- Automatic artifact uploads
+- Release asset publishing
+- Caching for faster builds
+
+**Artifacts:**
+- **macOS**: DMG installer and .app bundle
+- **Windows**: MSI and NSIS installers
+- **Linux**: DEB package and AppImage
+
+### 🧪 `ci.yml` - Continuous Integration
+**Triggers:** Push to main/develop, Pull Requests
+
+**Purpose:** Code quality checks and testing
+
+**Features:**
+- Frontend build verification
+- Rust formatting and linting (rustfmt, clippy)
+- Rust unit tests
+- Security audits for both frontend and backend dependencies
+
+### 🚀 `release.yml` - Manual Release
+**Triggers:** Manual workflow dispatch
+
+**Purpose:** Create tagged releases with built applications
+
+**Features:**
+- Manual version input
+- Pre-release option
+- Automatic release notes generation
+- Cross-platform builds and uploads
+- Comprehensive installation instructions
+
+**Usage:**
+1. Go to Actions tab in GitHub
+2. Select "Release" workflow
+3. Click "Run workflow"
+4. Enter version (e.g., v1.0.0)
+5. Choose if it's a pre-release
+6. Click "Run workflow"
+
+### 🔄 `dependencies.yml` - Dependency Management
+**Triggers:** Weekly schedule (Mondays 9 AM UTC), Manual dispatch
+
+**Purpose:** Automated dependency updates and security monitoring
+
+**Features:**
+- Weekly dependency updates
+- Automatic PR creation for updates
+- Security vulnerability detection
+- Automatic issue creation for security alerts
+
+## Setup Requirements
+
+### Repository Secrets
+No additional secrets are required beyond the default `GITHUB_TOKEN`.
+
+### Branch Protection (Recommended)
+Configure branch protection rules for `main` branch:
+- Require status checks to pass before merging
+- Require branches to be up to date before merging
+- Include status checks: `lint-and-test`, `security-audit`
+
+### Release Process
+
+#### Automated (Recommended)
+1. Merge changes to `main` branch
+2. Use the manual release workflow to create a new release
+3. The workflow will automatically build and upload all platform binaries
+
+#### Manual
+1. Create a new tag: `git tag v1.0.0`
+2. Push the tag: `git push origin v1.0.0`
+3. Create a release on GitHub
+4. The build workflow will automatically attach binaries
+
+## Platform-Specific Notes
+
+### macOS
+- Builds universal binaries (Intel + Apple Silicon)
+- Requires macOS 13.0 or later
+- DMG installer includes code signing (if certificates are configured)
+
+### Windows
+- Builds for x64 architecture
+- Provides both MSI and NSIS installers
+- Compatible with Windows 10 and later
+
+### Linux
+- Builds for x64 architecture
+- Provides DEB package for Debian/Ubuntu
+- Provides AppImage for universal Linux compatibility
+- Requires WebKit2GTK and other system dependencies
+
+## Troubleshooting
+
+### Build Failures
+1. Check the specific platform logs in the Actions tab
+2. Ensure all dependencies are properly declared
+3. Verify Tauri configuration is correct
+
+### Security Audit Failures
+1. Review the security report in the workflow logs
+2. Update vulnerable dependencies
+3. Consider using `pnpm audit --fix` for frontend issues
+4. Use `cargo update` for Rust dependency updates
+
+### Cache Issues
+If builds are failing due to cache corruption:
+1. Go to Actions tab
+2. Click on "Caches" in the sidebar
+3. Delete relevant caches
+4. Re-run the workflow
+
+## Customization
+
+### Adding New Platforms
+To add support for additional platforms, modify the `matrix` section in `build.yml`:
+
+```yaml
+matrix:
+  include:
+    - platform: 'macos-latest'
+      args: '--target aarch64-apple-darwin'
+      target: 'aarch64-apple-darwin'
+```
+
+### Modifying Build Steps
+Each workflow can be customized by:
+1. Adding new steps
+2. Modifying existing commands
+3. Adding environment variables
+4. Configuring different Node.js/Rust versions
+
+### Adding Code Quality Tools (Optional)
+If you want to add code quality tools in the future:
+1. **ESLint**: Add ESLint configuration and dependencies for JavaScript/TypeScript linting
+2. **Prettier**: Add Prettier for consistent code formatting
+3. **TypeScript strict checking**: Enable stricter TypeScript rules and type checking
+
+### Changing Schedule
+Modify the `cron` expression in `dependencies.yml` to change the update frequency:
+```yaml
+schedule:
+  - cron: '0 9 * * 1'  # Every Monday at 9 AM UTC
+```

+# LED Strip Test Device Auto-Refresh Implementation
+
+## Overview
+Implemented automatic refresh functionality for the device dropdown in the LED strip test interface. The device list now updates in real-time when devices are discovered, connected, or disconnected.
+
+## Changes Made
+
+### 1. Frontend Changes (`src/components/led-strip-test/led-strip-test.tsx`)
+
+#### Added Event Listener Import
+```typescript
+import { listen } from '@tauri-apps/api/event';
+```
+
+#### Enhanced Device Loading Logic
+- **Initial Load**: Still loads devices on component mount using `get_boards()`
+- **Real-time Updates**: Added listener for `boards_changed` events from backend
+- **Smart Selection**: Automatically handles device selection when devices are added/removed:
+  - If current device disconnects, automatically selects first available device
+  - If no device was selected and devices become available, selects the first one
+  - Properly cleans up event listeners on component unmount
+
+#### Improved UI Display
+- **Device Count**: Shows number of devices found in label
+- **Connection Status**: Each device option shows:
+  - Status icon (🟢 Connected, 🟡 Connecting, 🔴 Disconnected)
+  - Device name and address
+  - Connection status text
+- **Empty State**: Shows "Searching..." when no devices found
+
+#### Type Safety Improvements
+- Updated `BoardInfo` interface to match backend types
+- Proper handling of `connect_status` union type
+- Type-safe status checking functions
+
+### 2. Backend Integration
+The implementation leverages existing backend infrastructure:
+- **UdpRpc Manager**: Continuously searches for devices via mDNS
+- **Device Monitoring**: Checks device connectivity every second
+- **Event Broadcasting**: Sends `boards_changed` events to frontend
+- **Status Tracking**: Maintains real-time connection status for each device
+
+## Technical Details
+
+### Event Flow
+1. Backend `UdpRpc` discovers devices via mDNS service discovery
+2. Backend monitors device connectivity with periodic health checks
+3. Backend broadcasts `boards_changed` events when device list changes
+4. Frontend listens for events and updates UI automatically
+5. Frontend handles device selection logic intelligently
+
+### Connection Status Types
+- `Connected`: Device is responding to ping requests
+- `Connecting`: Device is in retry state (with retry count)
+- `Disconnected`: Device is not responding
+
+### Error Handling
+- Graceful fallback if initial device load fails
+- Proper cleanup of event listeners
+- Maintains UI state consistency during device changes
+
+## Benefits
+1. **Real-time Updates**: No need to manually refresh device list
+2. **Better UX**: Visual indicators for device status
+3. **Automatic Recovery**: Handles device disconnections gracefully
+4. **Type Safety**: Proper TypeScript types prevent runtime errors
+5. **Performance**: Efficient event-driven updates instead of polling
+
+## Implementation Status
+✅ **Completed**: LED Strip Test device dropdown auto-refresh
+✅ **Already Implemented**: Board Index page auto-refresh (was already working)
+✅ **Type Safety**: Fixed TypeScript type definitions for BoardInfo
+✅ **UI Improvements**: Added status indicators and device count display
+
+## Testing
+To test the functionality:
+1. Start the application with `npm run tauri dev`
+2. Navigate to LED Strip Test page
+3. Observe device list updates as devices come online/offline
+4. Verify status indicators show correct connection states:
+   - 🟢 Connected devices
+   - 🟡 Connecting devices (with retry count)
+   - 🔴 Disconnected devices
+5. Test device selection behavior when devices disconnect
+6. Check that device count is displayed in the label
+
+## Code Quality
+- ✅ No TypeScript errors
+- ✅ Proper event listener cleanup
+- ✅ Type-safe status checking
+- ✅ Consistent with existing codebase patterns
+- ✅ Follows SolidJS best practices
+
+## Future Enhancements
+- Add device refresh button for manual refresh
+- Show device discovery progress indicator
+- Add device connection retry controls
+- Display device ping latency information
+- Add device connection history/logs

+# LED Hardware Communication Protocol
+
+## Overview
+
+UDP-based bidirectional protocol for communication between desktop application and ambient light hardware boards. The protocol supports LED color data transmission, device health monitoring, and remote control capabilities.
+
+## Connection
+
+- **Protocol**: UDP
+- **Port**: 23042
+- **Discovery**: mDNS (`_ambient_light._udp.local.`)
+- **Example Board**: `192.168.31.206:23042`
+
+## mDNS Service Discovery
+
+### Service Registration (Hardware Side)
+
+Hardware boards must register the following mDNS service:
+
+- **Service Type**: `_ambient_light._udp.local.`
+- **Port**: 23042
+- **TXT Records**: Optional, can include device information
+
+### Service Discovery (Desktop Side)
+
+Desktop application continuously browses for `_ambient_light._udp.local.` services and automatically connects to discovered devices.
+
+## Protocol Messages
+
+The protocol uses different message headers to distinguish message types:
+
+| Header | Direction | Purpose | Format |
+|--------|-----------|---------|---------|
+| 0x01 | Desktop → Hardware | Ping (Health Check) | `[0x01]` |
+| 0x01 | Hardware → Desktop | Pong (Health Response) | `[0x01]` |
+| 0x02 | Desktop → Hardware | LED Color Data | `[0x02][Offset_H][Offset_L][Color_Data...]` |
+| 0x03 | Hardware → Desktop | Display Brightness Control | `[0x03][Display_Index][Brightness]` |
+| 0x04 | Hardware → Desktop | Volume Control | `[0x04][Volume_Percent]` |
+
+## Health Check Protocol (Ping/Pong)
+
+### Desktop → Hardware (Ping)
+
+```text
+Byte 0: Header (0x01)
+```
+
+### Hardware → Desktop (Pong)
+
+```text
+Byte 0: Header (0x01)
+```
+
+**Behavior:**
+
+- Desktop sends ping every 1 second to each connected device
+- Hardware must respond with pong within 1 second
+- Timeout or incorrect response triggers reconnection logic
+- After 10 failed attempts, device is marked as disconnected
+
+## LED Color Data Protocol
+
+### Packet Format
+
+```text
+Byte 0: Header (0x02)
+Byte 1: Offset High (upper 8 bits of LED start position)
+Byte 2: Offset Low (lower 8 bits of LED start position)
+Byte 3+: LED Color Data (variable length)
+```
+
+## LED Color Data
+
+### RGB LEDs (3 bytes per LED)
+
+```text
+[R][G][B][R][G][B][R][G][B]...
+```
+
+### RGBW LEDs (4 bytes per LED)
+
+```text
+[R][G][B][W][R][G][B][W][R][G][B][W]...
+```
+
+All values are 0-255.
+
+## Color Calibration
+
+Colors are calibrated before transmission:
+
+**RGB:**
+
+```rust
+calibrated_r = (original_r * calibration_r) / 255
+calibrated_g = (original_g * calibration_g) / 255  
+calibrated_b = (original_b * calibration_b) / 255
+```
+
+**RGBW:**
+
+```rust
+calibrated_r = (original_r * calibration_r) / 255
+calibrated_g = (original_g * calibration_g) / 255
+calibrated_b = (original_b * calibration_b) / 255
+calibrated_w = calibration_w  // Direct value
+```
+
+## Hardware Control Protocol (Hardware → Desktop)
+
+### Display Brightness Control
+
+Hardware can send display brightness adjustment commands to the desktop:
+
+```text
+Byte 0: Header (0x03)
+Byte 1: Display Index (0-based display number)
+Byte 2: Brightness (0-255, where 255 = 100% brightness)
+```
+
+**Example:** Set display 0 to 50% brightness
+
+```text
+03 00 80
+│  │  └─ Brightness (128 = ~50%)
+│  └─ Display Index (0)
+└─ Header (0x03)
+```
+
+### Volume Control
+
+Hardware can send system volume adjustment commands to the desktop:
+
+```text
+Byte 0: Header (0x04)
+Byte 1: Volume Percent (0-100)
+```
+
+**Example:** Set system volume to 75%
+
+```text
+04 4B
+│  └─ Volume (75%)
+└─ Header (0x04)
+```
+
+## Connection State Management
+
+### Connection States
+
+- **Unknown**: Initial state when device is first discovered
+- **Connecting**: Device is being tested, includes retry count (1-10)
+- **Connected**: Device is responding to ping requests normally
+- **Disconnected**: Device failed to respond after 10 retry attempts
+
+### State Transitions
+
+```text
+Unknown → Connecting(1) → Connected
+    ↓           ↓             ↓
+    ↓      Connecting(2-10)   ↓
+    ↓           ↓             ↓
+    └─→ Disconnected ←────────┘
+```
+
+### Retry Logic
+
+1. **Initial Connection**: When device discovered via mDNS
+2. **Health Check Failure**: If ping timeout or wrong response
+3. **Retry Attempts**: Up to 10 attempts with 1-second intervals
+4. **Disconnection**: After 10 failed attempts, mark as disconnected
+5. **Recovery**: Disconnected devices continue to receive ping attempts
+
+## Packet Examples
+
+### RGB Example
+
+3 RGB LEDs starting at position 0: Red, Green, Blue
+
+```text
+02 00 00 FF 00 00 00 FF 00 00 00 FF
+│  │  │  └─────────────────────────── 9 bytes color data
+│  │  └─ Offset Low (0)
+│  └─ Offset High (0)
+└─ Header (0x02)
+```
+
+### RGBW Example
+
+2 RGBW LEDs starting at position 10: White, Warm White
+
+```text
+02 00 0A FF FF FF FF FF C8 96 C8
+│  │  │  └─────────────────────── 8 bytes color data
+│  │  └─ Offset Low (10)
+│  └─ Offset High (0)
+└─ Header (0x02)
+```
+
+## Implementation Notes
+
+- **Byte Order**: Big-endian for multi-byte values (offset field)
+- **Delivery**: Fire-and-forget UDP (no acknowledgment required)
+- **Hardware Role**: Simple UDP-to-WS2812 bridge, no data processing
+- **LED Type Logic**: Handled entirely on desktop side, not hardware
+- **Mixed Types**: Same display can have both RGB and RGBW strips
+- **Data Flow**: Desktop → UDP → Hardware → WS2812 (direct forward)
+
+## Hardware Implementation
+
+The hardware board handles multiple protocol functions: UDP-to-WS2812 bridge for LED data, health monitoring, and optional control input capabilities.
+
+### Required Functions
+
+1. **mDNS Service Registration**: Advertise `_ambient_light._udp.local.` service
+2. **UDP Server**: Listen on port 23042 for incoming packets
+3. **Packet Processing**: Handle different message types based on header
+4. **Health Monitoring**: Respond to ping requests with pong
+5. **LED Control**: Forward color data to WS2812 strips
+6. **Optional Control**: Send brightness/volume commands to desktop
+
+### Packet Processing Logic
+
+```c
+void process_packet(uint8_t* data, size_t len) {
+    if (len < 1) return;
+
+    switch (data[0]) {
+        case 0x01: // Ping request
+            handle_ping(data, len);
+            break;
+

+
+### Optional Control Features
+
+Hardware can optionally send control commands to desktop:
+
+```c
+// Send display brightness control
+void send_brightness_control(uint8_t display_index, uint8_t brightness) {
+    uint8_t packet[3] = {0x03, display_index, brightness};
+    udp_send_to_desktop(packet, 3);
+}
+
+// Send volume control
+void send_volume_control(uint8_t volume_percent) {
+    uint8_t packet[2] = {0x04, volume_percent};
+    udp_send_to_desktop(packet, 2);
+}
+```
+
+### Key Implementation Notes
+
+- **Ping Response**: Must respond to ping (0x01) within 1 second
+- **LED Data**: Direct forward to WS2812, no processing required
+- **Control Commands**: Optional feature for hardware with input capabilities
+- **mDNS Registration**: Essential for automatic device discovery
+- **UDP Server**: Must handle concurrent connections from multiple desktops
+
+## Troubleshooting
+
+### Device Discovery Issues
+
+**Device Not Found**:
+
+- Verify mDNS service registration on hardware
+- Check service type: `_ambient_light._udp.local.`
+- Ensure port 23042 is accessible
+- Verify network connectivity between desktop and hardware
+
+**Device Shows as Disconnected**:
+
+- Check ping/pong response implementation
+- Verify hardware responds to 0x01 packets within 1 second
+- Monitor network latency and packet loss
+- Check UDP server implementation on hardware
+
+### LED Control Issues
+
+**No LED Updates**:
+
+- Verify hardware processes 0x02 packets correctly
+- Check WS2812 wiring and power supply
+- Monitor packet reception on hardware side
+- Verify offset calculations and LED strip configuration
+
+**Wrong Colors**:
+
+- Check color calibration settings on desktop
+- Verify RGB/RGBW data format matches LED strip type
+- Monitor color data in packets (bytes 3+)
+- Check WS2812 color order (GRB vs RGB)
+
+**Flickering or Lag**:
+
+- Monitor packet rate and network congestion
+- Check power supply stability for LED strips
+- Verify WS2812 data signal integrity
+- Consider reducing update frequency
+
+### Control Protocol Issues
+
+**Brightness/Volume Control Not Working**:
+
+- Verify hardware sends correct packet format (0x03/0x04)
+- Check desktop receives and processes control packets
+- Monitor packet transmission from hardware
+- Verify display index and value ranges
+
+### Connection State Issues
+
+**Frequent Disconnections**:
+
+- Check network stability and latency
+- Verify ping response timing (< 1 second)
+- Monitor retry logic and connection state transitions
+- Check for UDP packet loss
+
+**Stuck in Connecting State**:
+
+- Verify ping/pong packet format
+- Check hardware UDP server implementation
+- Monitor ping response timing
+- Verify network firewall settings
+
+### Network Debugging
+
+**Packet Monitoring**:
+
+```bash
+# Monitor UDP traffic on port 23042
+tcpdump -i any -X port 23042
+
+# Check mDNS service discovery
+dns-sd -B _ambient_light._udp.local.
+```
+
+**Hardware Debug Output**:
+
+- Log received packet headers and lengths
+- Monitor ping/pong timing
+- Track LED data processing
+- Log mDNS service registration status
+
+## Protocol Version
+
+- **Current**: 1.0
+- **Headers**: 0x01 (Ping/Pong), 0x02 (LED Data), 0x03 (Brightness), 0x04 (Volume)
+- **Future**: Additional headers for new features, backward compatibility maintained
