- Neue Funktionalität:
- `set_power_limit`: Ermöglicht die dynamische Steuerung des Entladelimits.
- Standardwert 5000 W bei `None` (Null-Punkt-Ausregelung).
- Validierung von Werten (nur 0-5000 W erlaubt).
- Schreibvorgänge erfolgen nur, wenn das bestehende Limit abweicht.
**Hinweis:** Für die aktive Steuerung muss der Speicher auf **Control Mode 4 (Remote)** gesetzt werden (`StorageConf_CtrlMode (0xE004)`).
Dies muss **extern** erfolgen und kann nicht von OpenWB automatisch übernommen werden.
Changes: - Replaced all non-ASCII characters (e.g., "Umlauts") with UTF-8-safe alternatives to avoid encoding issues. - Ensured all error and debug messages use encoding-safe text, replacing "Ungültige" with "Ungueltige".
- Added `blocked` mode to `set_power_limit` to set discharge limit to 0 W, allowing battery usage to be disabled (e.g., for fast charging without battery). <- not supported from OpenWB at moment - Introduced robust handling for advanced power control activation: - Confirm activation using a commit register (57741). - Ensured redundant writes are avoided through checks. - Improved validation logic for power limits with explicit error logging.
- Added detailed error messages for Modbus register read failures - Optimized power limit setting to avoid unnecessary writes"
- Refactored float conversion function - Ensured proper spacing after function definitions to comply with PEP8
