Can the Smart door and window contact detect a tilted window?

Yes, that is possible. The door and window contact detects an open, a closed and also a tilted window.
The door and window contact is taught-in after installation and determines a corresponding magnetic field for each of the states.
For example, the light in the garden can be switched on via the Premium gateway when the door is open and it is dark, while the heating is to be switched off when the door is open or tilted. Each state can be individually linked to targets.
