Issue with blinds after power cut

This is my Setup:

I have two blinds, each connected to one Shelly 2.5. The Shellys are integrated into HA. HomeKit is configured and worked till I cut the power to the room in which the blinds are located. The HA server is located in another room and did not suffer from the power cutoff.
Since that I am not able to controll the blinds from the Home App on iPhone. I can control them from HA and the Shelly App.
I should mention that the light in the specific room also is connected to a Shelly and that one works from the home App.

I already tried to delete the homekit.state file and reconfigure the Home app but it did not work.
Can someone help me troubleshoot this?
