Linak Desk: BT Error "Attribute can't be written"

Describe the bug Appreciate this tool @zewelor - trying to get it working on the IKEA Desk running on a Raspberry Pi. Only deviation from the manual is that I’m not running it in a python venv, but it appears the bug below is unrelated.

If I remember correctly, it works correctly for you with an IKEA Desk? Any pointers would be greatly appreciated!

if auto move is disabled, how are all of. the following able to do it: https://github.com/j5lien/esphome-idasen-desk-controller https://apps.apple.com/us/app/desk-remote-control/id1509037746 https://github.com/DWilliames/idasen-controller-mac

It might be that auto move is disabled is this controller. In mine I had to turn it on explicit via app ( and there was info not every controller will allow it ). Maybe you can find other controller and swap it ( not sure if there is any authorization between desk / controller )
