---

## 📊 Validation Results

✅ **Syntax Check**: Both files compile successfully
✅ **Structure Check**: Proper PyScript patterns detected
✅ **Import Check**: Standard library + PyScript built-ins
✅ **Error Handling**: Try-catch blocks present
⚠️ **Python Version**: Requires 3.9+ for zoneinfo
⚠️ **Dependencies**: Assumes helper entities exist

## 🔍 What We Need to Diagnose Further

To provide a definitive diagnosis, we need:

### Critical Information:
1. **Home Assistant logs** (Settings → System → Logs, filter "pyscript")
   - Look for errors after `pyscript.reload`
   - Any red/error messages mentioning the scripts

2. **Service availability** (Developer Tools → Services)
   - Do `pyscript.calculate_charging_schedule` and others appear?

3. **Entity existence** (Developer Tools → States)
   - Does `sensor.hastrom_flex_pro_ext` exist?
   - Does `pyscript.battery_charging_schedule` exist?
   - Do all helper entities exist?

4. **Manual test results**
   - What happens when calling `pyscript.getprices_extended`?
   - Any error notifications?

### Nice to Have:
- Home Assistant version
- PyScript version
- Python version (via `docker exec homeassistant python --version`)
- Complete log export

## 🎓 Understanding the Code

### Architecture Overview
```
Price Fetcher (hastrom_flex_extended.py)
    ↓
Creates: sensor.hastrom_flex_pro_ext
    ↓
Read by: Optimizer (battery_charging_optimizer.py)
    ↓
Creates: pyscript.battery_charging_schedule
    ↓
Read by: Executor (same file)
    ↓
Controls: input_boolean.goodwe_manual_control
    ↓
Triggers: Existing HA automations for battery control
```

### Key Components

**1. Price Fetcher**
- Fetches haStrom FLEX PRO prices
- Supports today + tomorrow data
- Creates two sensors with price arrays
- Runs hourly + special triggers at 14:05 and midnight

**2. Optimizer**
- Ranking-based algorithm
- Selects N cheapest hours from combined dataset
- Stores 48h schedule in state attributes
- Runs daily at 14:05 after price update

**3. Executor**
- Reads schedule hourly
- Matches current hour to schedule
- Toggles manual control on/off
- Sets charging power via helper

**4. Timezone Handling**
- All times in Europe/Berlin (CET/CEST)
- Uses zoneinfo for proper DST handling
- Requires Python 3.9+

---

## ⚠️ Known Limitations

1. **Timezone Module**: Requires Python 3.9+ (HA 2021.7+)
2. **State Size**: Large schedules might exceed limits
3. **Service Calls**: Internal service calls might have syntax issues
4. **Entity Dependencies**: Assumes 15+ helper entities exist
5. **API Dependency**: Requires haStrom API availability

---

## ✅ Success Criteria

The system is working correctly when:

### Price Fetcher Success:
- ✅ `sensor.hastrom_flex_pro_ext` exists
- ✅ Has `prices_today` array with 24 prices
- ✅ Has `prices_tomorrow` array (after 14:00)
- ✅ `last_update` shows recent timestamp
- ✅ Logs show: "📊 haStrom FLEX PRO Extended - Preise aktualisiert"

### Optimizer Success:
- ✅ `pyscript.battery_charging_schedule` exists
- ✅ Has `schedule` array with ~45-48 entries
- ✅ Has `num_charges` > 0 (if battery not full)
- ✅ `input_text.battery_optimizer_status` shows "X Ladungen"
- ✅ Logs show: "=== Optimierung abgeschlossen ==="

### Executor Success:
- ✅ Runs every hour at :05
- ✅ Finds matching schedule entry
- ✅ Toggles `input_boolean.goodwe_manual_control` correctly
- ✅ Sets `input_number.charge_power_battery` during charge hours
- ✅ Logs show: "🔋 AKTIVIERE LADEN" or "✓ Auto-Modus bereits aktiv"

2. Enable debug logging
3. Test each component manually
4. Document findings

### Medium Term (This Week):
1. Verify all helper entities exist
