Open the menu in the Nuki app (top left) and choose “App settings” to enter the general settings of your app. There you can configure the sound and vibration feedback of the Nuki app.
Furthermore you can de-/activate the debug mode. When you activate the debug mode, the Nuki app stores a record of the events in your Nuki app, which helps us a lot at finding the cause of any error you report to us. With your help we can make the Nuki app even better!
