What happened?

Smartwings WM25L-Z has started to be reported as running on AC power when it is running on battery but has the solar charging panel attached.

What did you expect to happen?

Whe it was first added to z2m it was correctly identified as on battery. I cannot specifically say when this change started. I only just noticed it now as I was curious about the current battery level of the different shades.

It still reports as AC instead of battery in z2m v1.38.0 (HAOS addon) even though the interview shows the battery level being exposed. Re-interviewing or re-configuring makes no difference.
