@koltipelto not the right place.to ask for help. This is an issue tracker for the core, not a support forum. Also, that error message is documented. You either have bad wiring or a dead module. From your drawing, I think it's bad wiring. Closing per issue policy doc.

@devyte Thanks a lot! Was a bad wiring! Sorry for the post!
