I got it. Problem was a driver I installed for the panel.

My actions list is empty, but the stobes are working with this switch. And if I add an action to the list, the new action works, but strobes go on too.
I don‘t know how to delete the default.

Device settings are all on (send initial switches, swap r/l... and Virtual Power Support)

no one knows what I mean?! Or how do you manage that?

Hello,

I'm a little bit desperate.
If I assign a switch, the basic control is retained. When I put the ATC on the light switch, the ATC goes on, but so does the light.

How can I delete or block the basic settings?
