Danalock V3-BTZE not working in openHAB 3.1.0.M4

Controller was cleaned up and lock was reset before all attemps. That’s why I guess exclusion with the UI insted of doing it direct on the controller helped to clean Openhab catch if there is. I do not know that deep of the binding. Surely I had to move controller back to UI, verify Secure Inclusion Mode setting of the contoller and I needed to do all other steps what was advised by You and Chris. So many thanks for that!
