Nuki Smart Lock
It seems like there is no Widget for Android yet. It would be great if one could lock or unlock and maybe do other actions directly from the homescreen without having to open the app. A widget for iOS is already implemented as it seems.
Customizable, at least lock and unlock. Show status of the door (opened, closed, locked, unlocked).
Take your smartphone and unlock your door from the home screen without having to open the app.
