V42.0.4 – Bug Fixes - based on findings from users (GitHub + Simon42 Forum)

Fuel my late-night ideas with a coffee? I'd really appreciate it — keep this project running!

Buy Me a Coffee

Here are the most important changes:
Home Assistant 2026.8.x ready!

Astronomy Data & Startup Issues

  • The error “SFML astronomy database is unavailable or invalid” / “database is locked” has been fixed.
    The integration now accesses the astronomy data cleanly and in a controlled way.
  • Short delays when accessing the database no longer cause the morning forecast to abort.
  • The misleading message “refresh was coalesced” no longer appears.
  • Normal database activities during startup are no longer falsely reported as errors.
  • When reloading or unloading the integration, no delayed background tasks keep running.
  • Database timing control is more robust and now also works with Home Assistant 2026.8.x.

AI Model Management

  • The first AI model can now be activated more reliably as soon as enough comparison data is available.
  • Selection of the best model candidates has been improved:
    – Candidates with already collected shadow evidence are still preferred.
    – If no candidate has useful evidence, the qualitatively best model is chosen (instead of simply the oldest one).
  • Previously deferred model candidates can now be re-evaluated in a controlled way without rewriting the immutable model history.

Shading Detection

  • Complete group data is no longer incorrectly discarded as “incomplete”.
  • Under rain and heavy cloud cover, reduced production is no longer so quickly classified as “local shading” (trees, buildings, etc.) – especially when no local irradiance or lux sensor is available.
  • The diagnosis now more clearly distinguishes between:
    – general loss compared to an ideal clear sky and
    – actual local shading.

MPPT Detection

  • Battery limitations, zero-export situations, unexpected cloud cover, etc. are no longer shown as “MPPT throttling” by default.
    Only hours that were actually classified as MPPT throttling now appear as such.

Diagnostic Attributes

  • The displayed values (feature count, training data, last training time, model status, current shading, etc.) are now always taken from the current runtime and database state and no longer from a possibly outdated cache.

If you have any questions or notice further issues, just let me know.
