Setup failed after update home assistant

[Mybestplace]

After updating Home Assistant to 2025.11.0b2, this integration no longer works.
It keeps saying "Setup failed." I can remove an air conditioner, and then it sees that one can be added, but this one also fails to set up.

Before the update, the air conditioners worked perfectly.

Anyone know how I can solve this?
