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.
Features
Customizable, at least lock and unlock. Show status of the door (opened, closed, locked, unlocked).
Reason
Usability.
Examples
Take your smartphone and unlock your door from the home screen without having to open the app.
Note: Facing several restrictions which prevent us from reliably showing the current lock state in the widget, the state is not part of the widget implementation.
