ECHONETLite Home Assistant Custom Component v4.0.3

What's Changed

🐛 Bug Fixes

• Fixed cover position fallback behavior — Added fallback logic for current_cover_position when ENL_OPENING_LEVEL is not available. Covers now properly report position (0%, 50%, 100%) using ENL_OPENCLOSE_STATUS for devices that don't support positional reporting (#252)

• Fixed duplicate EPC codes in batch property requests — Resolved issue where duplicate EPC codes (0x80 and 0x97) in polling flags could cause some devices (confirmed on Fujitsu Nocria) to reject requests and stop responding. Requires power-cycle for recovery (#246, fixes related to #232)

• This fixes issue #258 and #250 where EV Charger/Discharger and LAN Distribution board were both incorrectly defined in pychonet.

• Pychonet has been bumped to version 2.7.8 to fix the above issues. Version 4.0.2 has been yanked.

🏗️ Architecture: DataUpdateCoordinator Migration (v4.0)

This release builds on the v4.0 foundation which introduced Home Assistant's native DataUpdateCoordinator pattern across all entity platforms. Key changes include:

• Centralized data polling — Replaced per-entity polling with a single shared DataUpdateCoordinator that batches ECHONETLite property requests efficiently
• Split connector architecture — Extracted the ECHONETConnector logic from __init__.py into its own dedicated module for better separation of concerns
• Entity refactoring — All entity platforms (climate, sensor, cover, switch, fan, select, light, binary_sensor) now extend CoordinatorEntity and access data via self.coordinator.data instead of direct connector references
• Push-to-polling decoupling — ECHONETLite push notifications are handled by the connector, while entities poll independently through the coordinator for state consistency
• Post-set verification polling — Added explicit polling after property set operations to verify values were applied correctly (replaced optimistic UI updates)

🔧 Dependencies

Updated pychonet requirement from 2.7.0 to 2.7.4 — Includes upstream improvements for ECHONETLite protocol handling

📝 Improvements

Improved debug logging messages — Clarified and standardized log messages throughout config_flow.py and init.py for better troubleshooting:
"ECHONET" → "ECHONETLite" where appropriate for consistency
More descriptive context in IP change detection logs
Removed redundant debug statements in climate.py
