Phase 1 Complete: Preparation & Cleanup

Directory structure:
- Created src/sensorpajen/ for new Python package
- Created config/ for configuration templates
- Created legacy/ for old scripts
- Created systemd/ and debian/ for future phases

Package setup:
- Added pyproject.toml with modern Python packaging
- Created package __init__.py
- Defined dependencies: bluepy, paho-mqtt

Configuration:
- Created config/sensors.json.example (converted from INI)
- Created config/sensorpajen.env.example for environment variables
- All 8 Xiaomi sensors migrated to JSON format

Cleanup:
- Removed temperatur_koksfonstret.py (DHT11 functionality)
- Moved all legacy scripts to legacy/ folder:
  - LYWSD03MMC.py
  - bluetooth_utils.py
  - sendToMQTT.sh
  - sensorer.sh
  - startup.sh
  - sensorer.ini

Updated ROADMAP.md to mark Phase 1 as complete.

Next: Phase 2 - Python Package Structure

 ## Migration Phases
 
-### Phase 1: Preparation & Cleanup ✓ TODO
+### Phase 1: Preparation & Cleanup ✅ DONE (2025-12-27)
 **Goal**: Reorganize repository without breaking existing functionality
 
+**Notes**: 
+- Created modern Python package structure with src/ layout
+- Converted INI sensor config to JSON format (sensors.json.example)
+- Environment-based configuration instead of hardcoded values
+- DHT11 sensor functionality removed as planned
+- Legacy scripts preserved in legacy/ folder
+
 #### Tasks:
-1. Create new directory structure
+- ✅ Create new directory structure
-   ```bash
+- ✅ Create pyproject.toml with dependencies
-   mkdir -p src/sensorpajen
+- ✅ Remove DHT11 functionality
-   mkdir -p config
+- ✅ Move legacy scripts to legacy/ folder
-   mkdir -p legacy
+- ✅ Create config file templates (sensors.json.example, sensorpajen.env.example)
-   mkdir -p systemd
+- ✅ Preserve requirements.txt for backward compatibility
-   mkdir -p debian
-   ```
-
-2. Create pyproject.toml with dependencies:
-   - bluepy
-   - paho-mqtt
-
-3. Remove DHT11 functionality:
-   - Delete temperatur_koksfonstret.py
-   - Remove DHT11 cron job from documentation
-   - Update README.md
-
-4. Move legacy scripts to legacy/ folder:
-   - LYWSD03MMC.py
-   - sendToMQTT.sh
-   - startup.sh
-   - sensorer.sh
-   - sensorer.ini
-   - bluetooth_utils.py
-
-5. Verify existing system still works with legacy scripts
