10-Jan-2026 Summary of Changes - SolarEdge Optimizers Integration

solaredgeoptimizers.py (Main API Module)

1. Logger setup: Added logging module setup to replace print statements.
2. Endpoint URL fix: Updated requestSystemData() URL from monitoringpublic.solaredge.com/publicSystemData to monitoring.solaredge.com/systemData, changed isPublic=true to false, and added locale and v (timestamp) parameters.
3. List/dict handling: Added handling for decodeResult() returning a list instead of a dict; extract the first element if it's a list.
4. Type checking: Added validation to ensure the result is a dict before accessing keys.
5. Safer dictionary access: Changed from direct key access to .get() for safer access.
6. Error handling: Added specific KeyError handling with improved logging.
7. Logging conversion: Replaced all print() statements with proper _LOGGER calls.
8. CSRF token handling: Added check for None CSRF token to prevent errors when missing.
9. Return value fix: Added explicit return None in GetThecsrfToken() if token not found.
10. Typo fixes: Fixed "concent" → "consent" in cookie string, and "paneel_desciption" → "paneel_description" (2 locations).

sensor.py (Sensor Platform)

1. Import fix: Changed from absolute to relative import to use local solaredgeoptimizers.py instead of site-packages version.
2. Typo fixes: Fixed "measerument" → "measurement" in log message, and "paneel_desciption" → "paneel_description" in attribute reference.
3. Code cleanup: Removed redundant else clause that did nothing.
4. Syntax fix: Changed comparison from not self._sensor_type is to self._sensor_type is not.

init_.py (Integration Setup)

1. Import fix: Changed from absolute to relative import to use local solaredgeoptimizers.py instead of site-packages version.

config_flow.py (Configuration Flow)

1. Import fix: Changed from absolute to relative import to use local solaredgeoptimizers.py instead of site-packages version.

Overall Impact

• Fixed API endpoint URL and parameters
• Improved error handling and logging
• Fixed import path issues to use local code
• Corrected typos and syntax issues
• Added proper type checking for API responses
• All changes documented with "AJT: 10-Jan-2025:" comments

These changes ensure the integration uses the local code files, handles API response variations, and provides better error reporting and logging.

11-Jan-2026 Summary of Changes - SolarEdge Optimizers Integration

Critical fixes (3)

1. File descriptor leak — Fixed in _doRequest() by using a context manager for Session() to ensure proper cleanup
2. Unsafe dictionary access — Replaced direct key access with .get() in SolarEdgeOptimizerData for measurements
3. Error handling — Added validation and error handling for getLifeTimeEnergy() and requestAllData() to prevent KeyErrors

Medium priority (4)

1. Resource management — All requests.get() calls now use context managers
2. Exception logging — Coordinator uses _LOGGER.exception() for full tracebacks
3. Cleanup — Added coordinator cleanup in async_unload_entry()
4. Date parsing — Added error handling with fallback for date parsing

Low priority (5)

1. Float conversion — Added try/except for string-to-float conversion in sensor updates
2. Code quality — Replaced % formatting with f-strings, improved docstrings, removed commented code, added status check for login response
