## 🚨 Emergency Quick Checks (5 Minutes)

### 1️⃣ Check PyScript Status
```
Settings → Devices & Services → Search "PyScript" → Should show "Configured"
```

### 2️⃣ Reload PyScript
```yaml
Developer Tools → Services → Call Service:
service: pyscript.reload
```

### 3️⃣ Check Logs for Errors
```
Settings → System → Logs → Filter "pyscript" → Look for RED messages
```

### 4️⃣ Verify Services Exist
```
Developer Tools → Services → Search "pyscript."
Should show: calculate_charging_schedule, execute_charging_schedule, getprices_extended
```

### 5️⃣ Check Files in Correct Location
```bash
# Via SSH or File Editor:
ls -la /config/pyscript/
# Should show: battery_charging_optimizer.py, hastrom_flex_extended.py
```

## 🔧 Common Fixes

### ❌ "ModuleNotFoundError: No module named 'zoneinfo'"

**Quick Fix**: Add fallback to both scripts

Replace in BOTH files:
```python
from zoneinfo import ZoneInfo
TIMEZONE = ZoneInfo("Europe/Berlin")
```

With:
```python
try:
    from zoneinfo import ZoneInfo
    TIMEZONE = ZoneInfo("Europe/Berlin")
except ImportError:
    import pytz
    TIMEZONE = pytz.timezone("Europe/Berlin")
```

Then: `pyscript.reload`

---

### ❌ "AttributeError: 'state' object has no attribute..."

**Cause**: Missing helper entity

**Quick Fix**: Create missing entities

Go to: `Settings → Devices & Services → Helpers → Create Helper`

**Required Helpers**:
- **Toggle**: `input_boolean.battery_optimizer_enabled` (initial: ON)
- **Toggle**: `input_boolean.goodwe_manual_control` (initial: OFF)
- **Toggle**: `input_boolean.battery_optimizer_manual_override` (initial: OFF)
- **Number**: `input_number.battery_capacity_kwh` (min: 0, max: 50, initial: 10)
- **Number**: `input_number.battery_optimizer_min_soc` (min: 0, max: 100, initial: 20)
- **Number**: `input_number.battery_optimizer_max_soc` (min: 0, max: 100, initial: 100)
- **Number**: `input_number.battery_optimizer_max_charge_power` (min: 0, max: 10000, initial: 5000)
- **Number**: `input_number.charge_power_battery` (min: 0, max: 10000, initial: 0)
- **Text**: `input_text.battery_optimizer_status` (max: 255)

Then: `pyscript.reload`

---

### ❌ Services Not Showing Up

**Cause**: PyScript didn't load scripts

**Quick Fix**:
1. Check file location: `/config/pyscript/` (not `pyscripts`)
2. Check file permissions: Should be readable by HA
3. Call: `pyscript.reload`
4. Check logs immediately for errors

---

### ❌ "NameError: name 'task' is not defined"

**Cause**: PyScript not initialized or wrong version

**Quick Fix**:
1. Check PyScript version: Settings → Devices & Services → PyScript
2. Update to latest: HACS → PyScript → Update
3. Restart Home Assistant
4. Call: `pyscript.reload`

---

### ❌ Time Triggers Not Firing

**Quick Fix**: Create automation instead

**configuration.yaml**:
```yaml
automation:
  - alias: "Battery Optimizer - Daily Calculation"
    trigger:
      platform: time
      at: "14:05:00"
    action:
      service: pyscript.calculate_charging_schedule

  - alias: "Battery Optimizer - Hourly Execution"
    trigger:
      platform: time_pattern
      minutes: "05"
    action:
      service: pyscript.execute_charging_schedule
```

Restart Home Assistant.

---

### ❌ Sensors Not Created (hastrom_flex_pro_ext)

**Quick Fix**: Check if price is None

Add logging to `hastrom_flex_extended.py` around line 86:
```python
log.info(f"DEBUG: current_price = {current_price}")
if current_price is not None:
    state.set("sensor.hastrom_flex_ext", value=float(current_price))
else:
    log.error("Current price is None - cannot create sensor")
```

Then: `pyscript.reload` and call `pyscript.getprices_extended`

---

## 🧪 Manual Test Sequence

**Run these in order to isolate the problem:**

### Test 1: Price Fetcher
```yaml
service: pyscript.getprices_extended
```
Wait 5 seconds, then check:
```
Developer Tools → States → sensor.hastrom_flex_pro_ext
Should have: prices_today, prices_tomorrow in attributes
```

### Test 2: Optimizer
```yaml
service: pyscript.calculate_charging_schedule
```
Wait 5 seconds, then check:
```
Developer Tools → States → pyscript.battery_charging_schedule
Should have: schedule array, num_charges, last_update
```

### Test 3: Executor
```yaml
service: pyscript.execute_charging_schedule
```
Immediately check logs:
```
Should see: "Suche Ladeplan für ..."
```

## 📋 Log Error Patterns & Fixes

| Error in Logs | Quick Fix |
|---------------|-----------|
| `ModuleNotFoundError: zoneinfo` | Add pytz fallback (see above) |
| `NameError: task` | Update PyScript integration |
| `AttributeError: state` | Create missing helper entity |
| `Fehler beim Abrufen` | Check network/API access |
| `SyntaxError` | Re-copy files, check encoding |
| `ValueError: State attributes` | Reduce schedule size |
| No errors, but not working | Check if optimizer is enabled |

---

## 🎛️ Enable/Disable Optimizer

### Enable
```yaml
service: input_boolean.turn_on
data:
  entity_id: input_boolean.battery_optimizer_enabled
```

### Disable
```yaml
service: input_boolean.turn_off
data:
  entity_id: input_boolean.battery_optimizer_enabled
```

### Check Status
```
Developer Tools → States → input_boolean.battery_optimizer_enabled
Should show: "on" or "off"
```

---

## 📊 Debug Logging

**configuration.yaml**:
```yaml
logger:
  default: info
  logs:
    custom_components.pyscript: debug
```

Restart, then check logs again.

---

## ✅ Success Indicators

### Price Fetcher Working:
```
Log shows: "✓ API-Abfrage erfolgreich: 48 Datenpunkte"
State exists: sensor.hastrom_flex_pro_ext with prices_today array
```

### Optimizer Working:
```
Log shows: "=== Batterie-Optimierung gestartet" ... "=== Optimierung abgeschlossen ==="
State exists: pyscript.battery_charging_schedule with schedule array
Status shows: "X Ladungen" in input_text.battery_optimizer_status
```

### Executor Working:
```
Log shows: "🔋 AKTIVIERE LADEN" OR "✓ Auto-Modus bereits aktiv"
Manual control toggles: input_boolean.goodwe_manual_control changes state
```
