+# GA Conflict Detection Tests
+
+## Overview
+
+The KNX IP usermod includes comprehensive GA (Group Address) conflict detection tests to ensure that per-segment KNX functionality doesn't create duplicate or conflicting addresses. All test files are centralized in this `/test/` directory for better organization.
+
+**Test Files in this directory:**
+- `test_ga_conflicts.cpp` - Main GA conflict test implementation
+- `knx_segment_tests.h` - Integration test framework
+- `README_TESTING.md` - General testing documentation
+
+This documentation explains how to run and interpret the GA conflict detection tests.
+
+## What GA Conflicts Are
+
+When using per-segment KNX functionality, each segment gets its own calculated GAs based on:
+- Central GAs (configured in settings)
+- Segment offsets (L, M, N parameters)
+- Segment index
+
+**Conflicts occur when:**
+1. Segment 0 uses the same GA as central addresses (offset = 0)
+2. Different segments calculate to the same GA
+3. Calculated GAs exceed KNX limits (31/7/255)
+
+## Test Functions Available
+
+### 1. `testGAConflictDetection()`
+Tests the core conflict detection algorithms:
+- ✓ Valid configurations (no conflicts)
+- ✓ Zero offset detection (segment 0 = central)
+- ✓ Cross-segment conflicts
+- ✓ Individual GA usage checking
+- ✓ Boundary validation
+
+### 2. `testValidationIntegration()`
+Tests integration with registration system:
+- ✓ Registration prevention with conflicts
+- ✓ Successful registration without conflicts
+- ✓ State preservation and cleanup
+
+### 3. `runGAConflictTests()`
+Runs all GA conflict tests in sequence with detailed output.
+
+## How to Run the Tests
+
+### Method 1: Call from Setup (Automatic)
+
+Add to your usermod setup() or initialization:
+
+```cpp
+void setup() {
+ // ... existing setup code ...
+
+ #ifdef KNX_UM_DEBUG
+ // Run GA conflict tests on startup
+ knxUsermod.runGAConflictTests();
+ #endif
+}
+```
+
+### Method 2: Manual Test Execution
+
+In your code, call the test functions directly:
+
+```cpp
+// Run all GA conflict detection tests
+knxUsermod.runGAConflictTests();
+
+// Or run individual tests
+knxUsermod.testGAConflictDetection();
+knxUsermod.testValidationIntegration();
+```
+
+### Method 3: Integrated with Existing Tests
+
+The GA conflict tests are already integrated into the main test suite in `knx_segment_tests.h`:
+
+```cpp
+void KnxIpUsermod::runSegmentTests() {
+ // ... existing segment tests ...
+
+ // GA conflict tests
+ testGAConflictDetection();
+ testValidationIntegration();
+}
+```
+
+## Understanding Test Output

+
+### Failed Test Indicators
+
+Look for ✗ symbols which indicate test failures:
+
+```
+[KNX-TEST] ✗ Unexpected conflicts with valid offsets
+[KNX-TEST] ✗ Should have detected conflicts with zero offsets
+[KNX-TEST] ✗ Registration should have failed
+```
+
+## Test Configuration
+
+### Debug Output
+
+Enable debug output by defining `KNX_UM_DEBUG` in your build flags:
+
+```ini
+# In platformio.ini
+build_flags =
+ -DKNX_UM_DEBUG
+```
+
+### Test Data
+
+The tests use predefined configurations:
+- **Valid config**: Large offsets (L=10, M=0, N=50) to avoid conflicts
+- **Conflict config**: Zero offsets to force segment 0 = central conflicts
+- **Cross-segment**: Small offsets (L=1) to create overlapping GAs
+
+## GA Conflict Analysis Tool
+
+The tests include a detailed analysis tool that shows:
+
+```
+[KNX-UM] ==========================================
+[KNX-UM] GA Conflict Analysis
+[KNX-UM] ==========================================
+[KNX-UM] Current configuration:
+[KNX-UM] - Segments: 3
+[KNX-UM] - Offsets: L=1, M=0, N=0
+[KNX-UM] Central GAs:
+[KNX-UM] - Power IN: 1/2/10, OUT: 1/2/11
+[KNX-UM] - Brightness IN: 2/2/10, OUT: 2/2/11
+[KNX-UM] - Effect IN: 3/2/10, OUT: 3/2/11
+[KNX-UM] Calculated segment GAs:
+[KNX-UM] Segment 0:
+[KNX-UM] Power IN : 1/2/10 ✓
+[KNX-UM] Power OUT: 1/2/11 ✓
+[KNX-UM] Bri IN : 2/2/10 ⚠ CONFLICT
+[KNX-UM] Bri OUT : 2/2/11 ⚠ CONFLICT
+[KNX-UM] ==========================================
+```
+
+## Troubleshooting Test Failures
+
+### Common Issues
+
+1. **Tests not running**: Ensure `KNX_UM_DEBUG` is defined
+2. **Compilation errors**: Check that test methods are declared in header
+3. **Memory issues**: Tests save/restore configuration, ensure sufficient heap
+
+### Debugging Steps
+
+1. Check serial output for detailed test logs
+2. Use `analyzeGAConflicts()` for detailed conflict analysis
+3. Verify segment configuration with `printSegmentConfiguration()`
+4. Test individual GA checking with `isGAInUse(ga)`
+
+## Integration with CI/CD
+
+The tests can be integrated into automated testing:
+
+```cpp
+bool runAutomatedTests() {
+ KNX_UM_DEBUGF("[AUTO-TEST] Starting automated GA conflict tests\n");
+
+ // Run tests and capture results
+ // Return false if any test fails
+
+ return true; // All tests passed
+}
+```
+
+## Best Practices
+
+1. **Run tests after configuration changes**: Always test after modifying GA settings or offsets
+2. **Test with real segment counts**: Use actual segment numbers from your setup
+3. **Validate before deployment**: Run full test suite before deploying to production
+4. **Monitor test output**: Check for warnings and suggestions in test logs
+
+## Test Coverage
+
+The GA conflict detection tests cover:
+
+- ✅ Basic conflict detection algorithms
+- ✅ Edge cases (zero offsets, boundary limits)
+- ✅ Integration with registration system
+- ✅ Configuration save/restore
+- ✅ Memory management
+- ✅ Cross-segment validation
+- ✅ Individual GA usage tracking
+
+This comprehensive test suite ensures reliable GA conflict prevention in production deployments.

+# GUI Error Message Debugging Guide
+
+This document explains the complete solution for displaying detailed KNX GA conflict messages in the WLED GUI.
+
+## Problem Description
+
+Users reported that when KNX Group Address conflicts were detected, the WLED GUI only showed "Error33:" instead of the detailed conflict information including specific GA addresses and recommendations.
+
+## Root Cause Analysis
+
+The issue was traced to the web interface JavaScript code not handling:
+1. Error code 33 (ERR_KNX_GA_CONFLICT)
+2. The `error_msg` field containing detailed error information
+
+## Complete Solution
+
+### 1. Backend Error Details (Already Implemented)
+- **File**: `/wled00/wled.h`
+ - Added global `errorDetails[256]` buffer for detailed error messages
+- **File**: `/wled00/const.h`
+ - Added `ERR_KNX_GA_CONFLICT = 33` error code
+- **File**: `/wled00/json.cpp`
+ - Enhanced JSON API to include `error_msg` field when `errorDetails` contains data
+ - Added debug output to track error message transmission
+- **File**: `/usermods/KNX_IP/usermod_knx_ip.cpp`
+ - Enhanced `hasGAConflicts()` to populate `errorDetails` with specific conflict information
+ - Fixed `sizeof()` issue with extern buffer declaration
+ - Added debug output to verify error details content
+
+### 2. Frontend JavaScript Fix (New Implementation)
+- **File**: `/wled00/data/index.js`
+ - Added case 33 handling in error switch statement
+ - Added support for `error_msg` field from JSON API response
+ - Enhanced error display to use detailed messages when available
+
+## Code Changes Made
+
+### JavaScript Error Handling Enhancement
+```javascript
+// Added case 33 for KNX GA conflicts
+case 33:
+ errstr = "KNX Group Address conflict detected.";
+ break;
+
+// Use detailed error message if available
+if (s.error_msg && s.error_msg.length > 0) {
+ errstr = s.error_msg;
+}
+```
+
+### C++ Debug Output for Troubleshooting
+```cpp
+// In hasGAConflicts() - fixed buffer size calculation
+const size_t errorDetailsSize = 256;
+strncpy(errorDetails, message.c_str(), errorDetailsSize - 1);
+errorDetails[errorDetailsSize - 1] = '\0';
+
+// Added debug output to verify content
+KNX_UM_DEBUGF("Error details set: '%s'", errorDetails);
+```
+
+### JSON API Debug Output
+```cpp
+// In json.cpp - added debug tracking
+if (errorDetails[0] != '\0') {
+ root[F("error_msg")] = errorDetails;
+ #ifdef WLED_DEBUG
+ Serial.printf("[JSON] Adding error details: '%s'\n", errorDetails);
+ #endif
+ errorDetails[0] = '\0'; // Clear after sending
+}
+```
+
+## Testing Process
+
+### 1. Build Process
+```bash
+# Build web interface (required after JavaScript changes)
+npm run build
+
+# Build firmware
+pio run -e esp32dev
+
+# Upload firmware (optional, for live testing)
+pio run -e esp32dev -t upload
+```
+
+### 2. Expected Debug Output
+When GA conflicts occur, you should see:
+```
+[KNX-UM] Error details set: 'KNX GA conflicts: 1/1/1, 1/1/2, 2/1/1, 2/1/2. Check segment offsets.'
+[JSON] Adding error details: 'KNX GA conflicts: 1/1/1, 1/1/2, 2/1/1, 2/1/2. Check segment offsets.'
+```
+
+### 3. Expected GUI Behavior
+Instead of showing:
+```
+Error33:
+```
+
+The GUI should now display:
+```
+Error 33: KNX GA conflicts: 1/1/1, 1/1/2, 2/1/1, 2/1/2. Check segment offsets.
+```
+
+## Build Requirements
+
+### Web Interface Build Required
+When JavaScript files are modified, the web interface must be rebuilt:
+1. Run `npm run build` to process JavaScript changes
+2. This converts JS/HTML/CSS files to C++ header files
+3. Rebuild firmware to include updated web interface
+
+### Debug Output Requirements
+- Enable `WLED_DEBUG` for JSON debug output
+- Enable `KNX_UM_DEBUG` for KNX usermod debug output
+
+## File Dependencies
+
+### Modified Files
+- `/wled00/data/index.js` - Frontend error handling
+- `/wled00/json.cpp` - JSON API with error_msg field
+- `/usermods/KNX_IP/usermod_knx_ip.cpp` - Backend error details
+
+### Generated Files (Auto-updated by build)
+- `/wled00/html_ui.h` - Contains compiled JavaScript from index.js
+
+## Troubleshooting
+
+### 1. Still seeing "Error33:" only
+- Verify web interface was rebuilt with `npm run build`
+- Check that firmware was rebuilt after web interface build
+- Enable debug output to verify error_msg transmission
+
+### 2. No error details in debug output
+- Verify `errorDetails` buffer is being populated in KNX usermod
+- Check that `errorFlag = ERR_KNX_GA_CONFLICT` is being set
+- Ensure JSON API is including error_msg field
+
+### 3. Build Issues
+- Run `npm install` if web build fails
+- Check that all modified files compile without errors
+- Verify PlatformIO environment is correctly configured
+
+## Future Enhancements
+
+### Potential Improvements
+1. **Localization**: Add multi-language support for error messages
+2. **UI Enhancement**: Create dedicated KNX configuration error dialog
+3. **Auto-resolution**: Suggest optimal GA offset values automatically
+4. **Export/Import**: Save/load KNX configurations with conflict checking
+
+### Error Code Extension
+The enhanced error handling system can be extended for other usermods:
+- Use global `errorDetails` buffer for detailed messages
+- Add specific error codes to the JavaScript switch statement
+- Include `error_msg` field in JSON responses for rich error information

+# KNX GA Conflict GUI Error Notifications
+
+## Overview
+
+The KNX IP usermod now provides **automatic GUI error notifications** when Group Address (GA) conflicts are detected. These errors appear directly in the WLED web interface, making it easy for users to identify and resolve GA conflicts without needing to check serial logs.
+
+## How It Works
+
+### Automatic Detection
+The system automatically checks for GA conflicts in several scenarios:
+1. **During setup** - After KNX initialization
+2. **After configuration changes** - When settings are saved via GUI
+3. **Manual trigger** - Via `checkGAConflictsAndNotifyGUI()` method
+
+### GUI Error Display
+When conflicts are detected:
+- **Error flag is set** in WLED's error system (`errorFlag = 33`)
+- **Error message appears** in the WLED web interface
+- **Red notification** is displayed to the user
+- **Error persists** until conflicts are resolved
+
+## Error Code
+
+**Error Code: 33** - `ERR_KNX_GA_CONFLICT`
+- **Description**: KNX Group Address conflict detected (duplicate GAs)
+- **Location**: Added to `/wled00/const.h`
+- **Usage**: Automatically set by KNX usermod when conflicts are found
+
+## When Errors Are Triggered
+
+### 1. **Zero Offset Conflicts**
+```
+Segment 0 GAs = Central GAs (offsets L=0, M=0, N=0)
+→ GUI Error: "KNX GA conflict detected"
+```
+
+### 2. **Cross-Segment Conflicts**
+```
+Segment 1 Power GA = Segment 2 Brightness GA
+→ GUI Error: "KNX GA conflict detected"
+```
+
+### 3. **Central vs Segment Conflicts**
+```
+Segment N Power GA = Central Brightness GA
+→ GUI Error: "KNX GA conflict detected"
+```
+
+### 4. **Boundary Overflow**
+```
+Calculated GA exceeds KNX limits (31/7/255)
+→ GUI Error: "KNX GA conflict detected"
+```
+
+## User Experience
+
+### Error Notification Flow
+1. **User changes KNX settings** (GAs, segment offsets)
+2. **Settings are saved** via WLED GUI
+3. **Conflict detection runs** automatically
+4. **If conflicts found:**
+ - ❌ Error notification appears in GUI
+ - ⚠️ Segment registration is blocked
+ - 📋 Detailed conflict info in serial logs
+5. **If no conflicts:**
+ - ✅ Settings saved successfully
+ - ✅ Segment KOs registered normally
+
+### Resolving Errors
+To clear the GUI error notification:
+1. **Adjust segment offsets** (increase L, M, or N values)
+2. **Change central GAs** to different ranges
+3. **Reduce segment count** if using too many segments
+4. **Save settings** - error will clear automatically if no conflicts
+
+## Implementation Details
+
+### Key Methods
+
+**`checkGAConflictsAndNotifyGUI()`**
+- Checks for conflicts using existing `hasGAConflicts()` method
+- Sets `errorFlag = 33` if conflicts found
+- Clears `errorFlag = 0` if conflicts resolved
+- Logs detailed conflict info for debugging
+
+**`validateSegmentGAs()`** - Enhanced
+- Original validation logic preserved
+- Now sets GUI error flag when conflicts detected
+- Called during segment KO registration
+
+**`registerSegmentKOs()`** - Enhanced
+- Calls validation before registration
+- Sets GUI error flag if validation fails
+- Blocks registration when conflicts exist
+
+### Error Flag Integration
+```cpp
+// Set error flag for GUI notification
+extern byte errorFlag;
+errorFlag = 33; // ERR_KNX_GA_CONFLICT
+
+// Clear error flag when resolved
+extern byte errorFlag;
+if (errorFlag == 33) {
+ errorFlag = 0; // ERR_NONE
+}
+```
+
+### Automatic Triggers
+```cpp
+void setup() {
+ // ... KNX initialization ...
+
+ // Check for conflicts after setup
+ checkGAConflictsAndNotifyGUI();
+}
+
+bool readFromConfig(JsonObject& root) {
+ // ... configuration reading ...
+
+ // Check for conflicts after config changes
+ checkGAConflictsAndNotifyGUI();
+
+ return true;
+}
+```
+
+## Benefits
+
+### 🎯 **User-Friendly**
+- No need to check serial console
+- Immediate visual feedback in GUI
+- Clear indication of configuration problems
+
+### 🚀 **Proactive**
+- Catches conflicts before they cause issues
+- Prevents problematic KNX registrations
+- Validates configuration automatically
+
+### 🔧 **Developer-Friendly**
+- Detailed logging still available for debugging
+- Error state properly managed
+- Integration with WLED's existing error system
+
+### 📱 **Accessible**
+- Works on any device with web browser
+- No special tools or knowledge required
+- Consistent with WLED's user experience
+
+## Testing the Feature
+
+### 1. **Create a Conflict**
+- Set segment offsets to: L=0, M=0, N=0
+- Save settings
+- **Expected**: Red error notification in GUI
+
+### 2. **Resolve the Conflict**
+- Change offsets to: L=5, M=0, N=10
+- Save settings
+- **Expected**: Error notification disappears
+
+### 3. **Verify Logs**
+```
+[KNX-UM] GA conflicts detected - check WLED GUI for notification
+[KNX-UM] GA Conflict Analysis
+[KNX-UM] Segment 0: Power IN: 1/2/10 ⚠ CONFLICT
+```
+
+### 4. **Test Different Scenarios**
+- Cross-segment conflicts (overlapping ranges)
+- Boundary conditions (GAs > 31/7/255)
+- Multiple simultaneous conflicts
+
+## Technical Notes
+
+### Error Persistence
+- Error flag persists until conflicts are resolved
+- GUI shows error on every page load while flag is set
+- Error automatically clears when conflicts are fixed
+
+### Performance Impact
+- Minimal overhead during normal operation
+- Conflict checking only triggered when needed
+- No impact on KNX bus communication performance
+
+### Backward Compatibility
+- Existing installations continue to work unchanged
+- New error notifications are additive enhancement
+- Original validation warnings still appear in logs
+
+## Integration Examples
+
+### For Usermod Developers
+```cpp
+// Check and notify GUI of conflicts
+void checkConfiguration() {
+ knxUsermod.checkGAConflictsAndNotifyGUI();
+}
+
+// Manual conflict validation
+bool isConfigValid() {
+ return knxUsermod.validateSegmentGAs();
+}
+```
+
+### For End Users
+1. **Monitor GUI** for red error notifications
+2. **Check serial logs** for detailed conflict analysis
+3. **Adjust settings** based on error messages
+4. **Verify resolution** by confirming error disappears
+
+This feature significantly improves the user experience by making GA conflict detection visible and actionable directly in the WLED web interface! 🎯

+# KNX Group Address Table Display Feature
+
+This document describes the implementation of the KNX GA table display in the WLED Info panel.
+
+## Feature Overview
+
+The KNX GA table provides a comprehensive overview of all Group Address mappings for both the main group (segment 0) and individual segments. The table shows:
+
+- **Rows**: Different GA types (Power, Brightness, Effect) for both Input and Output
+- **Columns**: Main segment and individual segments (up to 8 segments displayed)
+- **Conflict Detection**: GAs that conflict with existing addresses are highlighted in red
+- **Offset Information**: Shows current L/M/N offset values used for segment calculations
+
+## Implementation Details
+
+### 1. Backend Implementation
+
+#### KNX Usermod Header (`usermod_knx_ip.h`)
+```cpp
+// GA table for Info panel display
+String getGATableHTML() const;
+
+// Added to Usermod API section
+void addToJsonInfo(JsonObject& root);
+```
+
+#### KNX Usermod Implementation (`usermod_knx_ip.cpp`)
+
+**GA Table Generation (`getGATableHTML()`)**:
+- Generates HTML table with segments as columns and GA types as rows
+- Uses `calculateSegmentGA()` to compute segment-specific addresses
+- Formats GAs in standard KNX notation (main/middle/sub)
+- Highlights conflicting GAs with red background
+- Includes offset information below the table
+- Limits display to 8 segments for readability
+
+**JSON Info Integration (`addToJsonInfo()`)**:
+- Called by WLED core when building `/json/info` response
+- Adds "KNX GA Table" field containing the HTML table
+- Only includes data when KNX usermod is enabled
+
+### 2. Frontend Implementation
+
+#### JavaScript Enhancement (`index.js`)
+
+**Usermod Data Processing**:
+```javascript
+var knxTable = "";
+if (i.u) {
+ for (const [k, val] of Object.entries(i.u)) {
+ if (k === "KNX GA Table" && typeof val === "string") {
+ // Special handling for KNX GA table - display as raw HTML
+ knxTable = val;
+ } else if (val[1]) {
+ urows += inforow(k,val[0],val[1]);
+ } else {
+ urows += inforow(k,val);
+ }
+ }
+}
+```
+
+**Info Panel Display**:
+```javascript
+${knxTable ? 'KNX Group Address Mapping ' + knxTable + ' |
' : ''}
+```
+
+## Table Structure
+
+### Column Layout
+- **Column 1**: GA Type (Power, Brightness, Effect)
+- **Column 2**: Main Segment (calculated for segment 0)
+- **Columns 3+**: Individual segments (Seg1, Seg2, etc.)
+
+### Row Sections
+1. **Input GAs (KNX → WLED)**: Commands from KNX bus to WLED
+2. **Output GAs (WLED → KNX)**: Status feedback from WLED to KNX bus
+
+### Visual Features
+- **Header Styling**: Uses CSS variables for consistent theming
+- **Conflict Highlighting**: Red background for conflicting GAs
+- **Compact Design**: Small font size and minimal padding for info panel
+- **Responsive Layout**: Adapts to available segments (max 8 displayed)
+
+## Example Table Output
+
+```
+┌─────────────┬──────────┬──────────┬──────────┬──────────┐
+│ GA Type │ Main │ Seg1 │ Seg2 │ Seg3 │
+├─────────────┼──────────┼──────────┼──────────┼──────────┤
+│ Input GAs (KNX → WLED) │
+├─────────────┼──────────┼──────────┼──────────┼──────────┤
+│ Power │ 1/0/1 │ 1/1/1 │ 1/2/1 │ 1/3/1 │
+│ Brightness │ 1/0/2 │ 1/1/2 │ 1/2/2 │ 1/3/2 │
+│ Effect │ 1/1/11 │ 1/2/11 │ 1/3/11 │ 1/4/11 │
+├─────────────┼──────────┼──────────┼──────────┼──────────┤
+│ Output GAs (WLED → KNX) │
+├─────────────┼──────────┼──────────┼──────────┼──────────┤
+│ Power │ 2/0/1 │ 2/1/1 │ 2/2/1 │ 2/3/1 │
+│ Brightness │ 2/0/2 │ 2/1/2 │ 2/2/2 │ 2/3/2 │
+│ Effect │ 2/1/11 │ 2/2/11 │ 2/3/11 │ 2/4/11 │
+└─────────────┴──────────┴──────────┴──────────┴──────────┘
+Offsets: L=0, M=1, N=0
+```
+
+## CSS Styling
+
+The table uses WLED's CSS variables for consistent theming:
+- `--c-2`: Header background
+- `--c-3`: Border color
+- `--c-4`: Section divider background
+- `--c-r`: Conflict highlighting (red)
+
+## Integration Points
+
+### 1. Info Panel Display
+- Table appears in the Info panel when KNX usermod is enabled
+- Positioned after other usermod information but before system info
+- Separated by horizontal rules for visual clarity
+
+### 2. JSON API Response
+- Included in `/json/info` endpoint under usermod section
+- Field name: "KNX GA Table"
+- Content: HTML string with complete table markup
+
+### 3. Real-time Updates
+- Table refreshes when Info panel is updated
+- Reflects current segment configuration and offset values
+- Shows conflicts based on current GA assignments
+
+## Build Requirements
+
+### Web Interface Build
+After modifying JavaScript files:
+```bash
+npm run build
+pio run -e esp32dev
+```
+
+### Dependencies
+- KNX usermod must be enabled
+- Requires segments to be configured in WLED
+- Uses existing GA conflict detection system
+
+## Future Enhancements
+
+### Potential Improvements
+1. **Interactive Features**: Click to edit GAs directly from table
+2. **Export Function**: Download table as CSV or PDF
+3. **Conflict Resolution**: Suggest optimal offset values
+4. **Color Coding**: Different colors for different GA types
+5. **Pagination**: Support for more than 8 segments
+6. **Tooltips**: Show GA descriptions and DPT types
+
+### Mobile Optimization
+- Consider horizontal scrolling for many segments
+- Responsive column width based on screen size
+- Collapsible sections for mobile view
+
+## Troubleshooting
+
+### Table Not Appearing
+1. Verify KNX usermod is enabled
+2. Check that segments are configured
+3. Ensure web interface was rebuilt after changes
+4. Verify JSON API includes "KNX GA Table" field
+
+### Styling Issues
+1. Check CSS variables are properly defined
+2. Verify table HTML structure is correct
+3. Test in different browsers for compatibility
+
+### Performance Considerations
+- Table generation is O(n) where n = number of segments
+- Limited to 8 segments for display performance
+- HTML string is cached until configuration changes

+### Legacy Test Files
+
+**`knx_pure_test.cpp`** - Original test suite (pre-existing)
+**`knx_pure_test_usermod.cpp`** - Usermod-specific version of pure tests
+
+## 🚀 Quick Start
+
+### Option 1: Enable Unit Tests (Recommended)
+
+1. **Add build flag** in `platformio.ini`:
+ ```ini
+ build_flags =
+ -D KNX_SEGMENT_UNIT_TESTS
+ -D KNX_UM_DEBUG
+ ```
+
+2. **Add declarations** to `usermod_knx_ip.h`:
+ ```cpp
+ #ifdef KNX_SEGMENT_UNIT_TESTS
+ bool unitTestCalculateSegmentGA();
+ bool unitTestMemoryManagement();
+ bool runUnitTests();
+ #endif
+ ```
+
+3. **Add implementations** from `knx_unit_tests.cpp` to `usermod_knx_ip.cpp`
+
+4. **Call from setup()**:
+ ```cpp
+ void setup() {
+ // ... existing setup code ...
+
+ #ifdef KNX_SEGMENT_UNIT_TESTS
+ runUnitTests();
+ #endif
+ }
+ ```
+
+### Option 2: Integration Tests
+
+1. **Add declarations** from `knx_segment_tests.h` to `usermod_knx_ip.h`
+2. **Add implementations** to `usermod_knx_ip.cpp`
+3. **Call manually** via serial command or web interface:
+ ```cpp
+ if (command == "knx-test") {
+ runSegmentTests();
+ }
+ ```
+
+### Option 3: Standalone Testing
+
+1. **Compile** `test_segment_knx.cpp` with a C++ compiler
+2. **Run** the executable for comprehensive offline testing
+
+## 🧪 Test Coverage
+
+### Address Calculation Tests
+- ✅ Formula validation: `Segment N = (central_main + L*N, central_middle + M*N, central_sub + N*N)`
+- ✅ Boundary condition validation (31/7/255 limits)
+- ✅ Invalid input handling (empty/malformed GAs)
+- ✅ Multiple offset configurations
+- ✅ Edge cases (segment 0, high segment numbers)
+
+### Memory Management Tests
+- ✅ Dynamic array allocation
+- ✅ Proper deallocation and cleanup
+- ✅ Zero-initialization verification
+- ✅ Null pointer handling
+- ✅ Memory leak prevention
+
+### Handler Tests
+- ✅ Segment power control
+- ✅ Segment brightness control
+- ✅ Segment effect control
+- ✅ Segment RGB control
+- ✅ Handler isolation (only affects target segment)
+
+### Integration Tests
+- ✅ KNX group object registration
+- ✅ Real segment detection
+- ✅ Live configuration validation
+- ✅ Performance under load
+

+[KNX-TEST] Registered segments: 3
+[KNX-TEST] Per-Segment KNX Tests Completed
+```
+
+## 🔧 Manual Testing Scenarios
+
+### Configuration Test
+1. Set segment offsets: L=1, M=0, N=10
+2. Set central power GA: 1/2/10
+3. Verify calculated segment GAs:
+ - Segment 0: 1/2/10 (central)
+ - Segment 1: 2/2/20
+ - Segment 2: 3/2/30
+
+### KNX Bus Test
+1. Send boolean '1' to segment 1 power GA → should turn on segment 1 only
+2. Send value '128' to segment 1 brightness GA → should set segment 1 to 50%
+3. Send value '5' to segment 2 effect GA → should change segment 2 effect
+4. Verify other segments remain unchanged
+
+### Performance Test
+1. Create 10+ segments
+2. Verify memory usage is reasonable
+3. Test KNX registration time
+4. Send rapid commands to different segments
+
+### Edge Case Test
+1. Test with 0 segments
+2. Test with 32+ segments (should limit to 32)
+3. Test with offsets that would exceed KNX limits
+4. Test segment index out of bounds
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+**Tests not running:**
+- Verify `KNX_SEGMENT_UNIT_TESTS` build flag is set
+- Check that function declarations are added to header
+- Ensure debug output is enabled with `KNX_UM_DEBUG`
+
+**Test failures:**
+- Check segment offset configuration (L≤31, M≤7, N≤255)
+- Verify central GA strings are valid
+- Ensure sufficient memory for segment arrays
+- Check that WLED segments are properly configured
+
+**Memory issues:**
+- Monitor free heap during tests
+- Verify `clearSegmentKOs()` is called before re-registration
+- Check for memory leaks with repeated test runs
+
+### Debug Output
+
+Enable verbose debug output:
+```ini
+build_flags =
+ -D KNX_UM_DEBUG
+ -D KNX_SEGMENT_UNIT_TESTS
+```
+
+Monitor serial output for detailed test progress and any failure messages.
+
+## 📈 Continuous Integration
+
+For automated testing in CI/CD pipelines:
+
+1. Add unit test build target
+2. Run tests during build process
+3. Fail build on test failures
+4. Generate test reports
+
+Example CI configuration:
+```yaml
+- name: Run KNX Unit Tests
+ run: |
+ pio run -e test_knx_segments
+ # Parse test output for failures
+```
+
+## 🤝 Contributing
+
+When adding new per-segment functionality:
+
+1. **Add unit tests** for new functions
+2. **Update integration tests** for end-to-end validation
+3. **Document test scenarios** in this README
+4. **Verify all tests pass** before submitting PR

+ *
+ * Scenario 3: Boundary Testing
+ * ----------------------------
+ * 1. Set central GA: "30/7/250"
+ * 2. Set segment offsets: L=2, M=1, N=10
+ * 3. Expected: Segment 1+ would exceed KNX limits
+ * 4. Result: Invalid GAs return 0, no conflicts reported

+ * With conflicts:
+ * [KNX-UM][CONFLICT] Segment GA 2/2/10 (0x1011) conflicts with existing GA
+ * [KNX-UM][ERROR] GA conflicts detected! Skipping segment KO registration

+# KNX IP Usermod Debug Logging
+
+The KNX IP usermod includes an optional verbose debug logging facility to help diagnose state publishing, change detection, GA configuration, and network behavior.
+
+## Overview
+Verbose logs are compiled in only when the preprocessor symbol `KNX_UM_DEBUG` is defined at build time. When disabled (default), almost all diagnostic `Serial` output from the KNX usermod is removed, minimizing flash size and runtime overhead.
+
+Logging is routed through macros defined in `usermods/KNX_IP/usermod_knx_ip.h`:
+
+```
+KNX_UM_DEBUGF(fmt, ...) // verbose printf-style log (enabled only with KNX_UM_DEBUG)
+KNX_UM_DEBUGLN(msg) // verbose single-line message
+KNX_UM_WARNF(fmt, ...) // warning (always on unless KNX_UM_SUPPRESS_WARN defined)
+KNX_UM_WARNLN(msg) // warning single-line message
+```
+
+If `KNX_UM_DEBUG` is not defined the DEBUG macros expand to no-ops and generate no code/data.
+Warnings are emitted unconditionally by default so that configuration or validation problems are visible even in production builds.
+
+To silence warnings (not generally recommended) add:
+```
+-DKNX_UM_SUPPRESS_WARN
+```
+to your `build_flags`. This converts `KNX_UM_WARN*` macros into no-ops as well.
+
+## Enabling Debug Logs (PlatformIO)
+Add a build flag for the environment you are using (example for a custom ESP32 dev environment) in `platformio_override.ini`:
+
+```
+[env:custom_esp32dev_knx_ip]
+extends = env:esp32dev
+build_flags =
+ ${common.build_flags}
+ -DKNX_UM_DEBUG
+```
+
+If you already have a `build_flags` section, just append `-DKNX_UM_DEBUG` on its own line (one flag per line is fine) or space separated on the same line.
+
+Rebuild and flash:
+```
+pio run -e custom_esp32dev_knx_ip -t upload
+```
+
+## What You Will See
+Typical debug lines (examples):
+```
+[KNX-UM] scheduleStatePublish() skipped - KNX not running (enabled=0, running=0)
+[KNX-UM] Power changed: 0→1
+[KNX-UM] Brightness changed: 12→34
+[KNX-UM] Color/CCT changed: R:0→128 G:0→64 B:0→32 W:0→10 CCT:128→140
+[KNX-UM] Scheduled publish in 120ms (pwr=1, bri=1, fx=0, cct=1, rgbw=1, preset=0)
+[KNX-UM] publishState(seq=5 at 123456ms) pendingFlags: PWR=1 BRI=1 FX=0 COLOR=1 PRE=0
+[KNX-UM] publishState(seq=5) done. Snapshot R=128 G=64 B=32 W=10 CCT=140 bri=86 on=1
+[KNX-UM] Scheduled publish triggered
+```
+
+These help answer:
+- Which fields were detected as changed
+- Whether multiple rapid changes were coalesced into a single publish
+- Sequence/order of publishes
+- Whether KNX stack was ready when a publish was attempted
+- Network IP change handling and GA registration rebuild events
+
+## Performance Impact
+With debug disabled (default) only warning lines (e.g. invalid GA / PA strings, sanity checks) still print using the WARN macros. Enabling debug:
+- Increases flash usage slightly (format strings + code)
+- Adds additional Serial I/O (can slow loop if baud is low)
+- Should not materially affect KNX timing, but for maximum performance keep it disabled in production
+
+## Disabling Again
+Simply remove or comment out the `-DKNX_UM_DEBUG` line and rebuild.
+
+## Adding New Debug Lines
+Prefer using the existing macros so they automatically follow the global enable/disable flag:
+```
+KNX_UM_DEBUGF("[KNX-UM] Something changed: val=%u\n", someValue);
+KNX_UM_DEBUGLN("[KNX-UM] Simple message");
+```
+Avoid raw `Serial.print*` calls for verbose info unless the message must always appear.
+
+## Testing Integration
+
+Debug output is particularly useful when running the test suites located in `/test/`:
+- Enable debug output with `-DKNX_UM_DEBUG`
+- Run tests from `/test/GA_CONFLICT_TESTS.md` to validate GA conflict detection
+- Use integration tests from `/test/README_TESTING.md` for end-to-end validation
+
+Example test output with debug enabled:
+```
+[KNX-TEST] Starting GA Conflict Detection Tests
+[KNX-UM] GA conflict detected: 1/2/10 used by both central and segment 0
+[KNX-TEST] ✓ Conflicts detected with zero offsets
+```
+
+## Related Settings
+`color_out_mode` (0=per-channel only, 1=composites only, 2=both) is often tuned while observing debug output to confirm the correct telegram set is sent.

+/*
+ * ESP-KNX-IP (ESP32-only, no webserver)
+ * Minimal KNXnet/IP core for embedding into apps like WLED.
+ *
+ * Features:
+ * - KNXnet/IP over UDP multicast (224.0.23.12:3671)
+ * - Send GroupValueWrite / GroupValueRead telegrams
+ * - Register per-GA callbacks for incoming GroupValueWrite/Read
+ * - No runtime web configuration, no storage by default
+ *
+ * Configuration ownership:
+ * - The host app (e.g., WLED usermod) should set the individual
+ * address and manage group objects itself.
+ *
+ * License: same as original project license or your fork's choice.
