Velux KLF200 with somfy IO screen (solar) position reported incorrectly

[rpiLovers]

since a few weeks the position of my somfy io (solar) screens do not report the correct position.
The electric powered screens work fine.
The position in the compleet open position (normally 100%) now returns 4%
Completely open is still 0%.
My automation is not working anymore due to the position error.
Does someone have the same issue?

I m running myvelux 2.9.13
HA version 2024.8.2 but in the former version problem was also there.

Hope someone can help how to correct this.

screens are fully open in this screenshot

Can you turn on the debugging of pyvlx and check what the KLF is reporting. Need to understand if this wrongly transmitted by the API or just an implementation issue on pyvlx and this custom_component. If the API is reporting this wrongly I cannot really help here, as I do not have any support from velux here.
