🔍 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"
