v1.9.0

v1.9.0 - 2026-02-16

Changed

• Complete rewrite of config_flow.py from scratch to eliminate 500 Internal Server Error issues during integration reconfiguration. The new implementation incorporates all lessons learned from previous versions:
  • Eliminated mixin pattern in favor of module-level helper functions with explicit hass parameter, improving type safety and reducing complexity
  • Centralized battery device fetching logic in _get_battery_devices_safe() function with comprehensive error handling that always returns a valid dict (never None)
  • Centralized schema creation in _create_threshold_schema() and _create_devices_schema() functions to eliminate code duplication
  • Improved device filtering in _create_devices_schema() to prevent validation errors when excluded devices no longer exist in Home Assistant
  • Enhanced error handling with granular try-except blocks that catch and log all exceptions with full stack traces
  • All error paths return functional forms with user-friendly error messages instead of causing 500 errors
  • Simplified OptionsFlowHandler to remove redundant code and improve maintainability
  • Proper async/await patterns throughout to ensure correct operation within Home Assistant's event loop
  • Better logging with debug and info level messages to facilitate troubleshooting
  • Code structure optimized for readability and future maintenance

Fixed

• HTTP 500 error when reconfiguring the integration through the UI. The previous v1.8.11 fixes were incomplete. This complete rewrite addresses all edge cases that could cause 500 errors:
  • Schema creation failures now have proper fallbacks
  • Device fetching errors are caught and return empty dict instead of propagating
  • Config entry access is properly protected with safe defaults
  • All form rendering paths are guaranteed to succeed even in error conditions
