ha-tahoma: Wrong state for Velux Shutters with Tahoma Switch & home assistant

Did you read the instructions?

• I have read the README, including the advanced debugging section.

The problem

I use Velux shutters as well as Somfy shutters connected to a Tahoma switch box. Home assistant is using the Tahoma switch through ha-tahoma integration.

Everything works well, except the state of two Velux shutters. Even if closed, they are reported as open in the history. Somfy shutters are well reported as closed.

The activated controls in the panel work well though : can only open if they the shutters are closed.

Home assistant runs on a raspberry pi 4. Home assistant in a docker container.

Thanks for all the very impressive work done so far !

What version of this integration (ha-tahoma) has the issue?

2.6.3

What version of Home Assistant Core has the issue?
