Or alternatively two reed contacts on the window. So you can distinguish between tilted and open. Another alternative would be an EnOcean window handle from e.g. Hoppe. This sends you also tilted and open based on the handle position. Unfortunately, the handle does not recognize whether a window was levered out. But for this the presence detectors should be in place. In addition, you can also detect if the patio door was possibly only ajar but I was closed by handle.
