Window handles with position feedback or window contacts?

I am currently making a plan regarding the implementation of our smart home in the new building. What is still not entirely clear to me is which basic system I will use. However, I am already gathering components to make comparisons.

Since I want to read the window and patio door status (Open, Closed, Tilted), I have researched and come to the following solutions:
1. Window handle with integrated Enocean transmitter (maintenance-free because it has no battery)
2. Wired window contacts connected to a flush-mounted box. Then routing the cables to the distribution box.
3. Window contacts with Tipp wireless without cables and without battery

For me, the window handles, for example from HOPPE, actually seem ideal. Does anyone have such window handles in use? Since I do not want to consider a closed patio door that is only pulled shut (the roller shutter should not close and lock me out if the patio door was only pulled shut), only such a handle would come into question, or is there a way to simulate this somehow with window contacts?

Wouldn't it be "smart" to choose these rotary handles here instead of wiring all windows to the distribution box (do all contacts have to be wired with a separate cable to the distribution box, or can this possibly be shortened with multi-core cables)?

One more question:
If the window is pried open, the rotary handle does not recognize this, right, or is there also a solution for this?

With Roto MvS contacts, you can easily do it just as you imagine. (Or with others with a similar arrangement/approach)

Smart is not measured by how much or how little cable you use, but by how secure and error-free the whole thing works, and the hardwired connection is a nose ahead of all wireless solutions.

Since I do not want to consider a sliding patio door as "closed" (the roller shutter should not close and lock me out if the patio door is only slid shut), only such a handle would be suitable, right, or is there a way to simulate this somehow with window contacts?

You simply position the reed (or the magnet) so that it opens by the movement of the handle. Ask the window maker, they have been doing this for decades, from alarm systems and such.

Edit: We have Siegenia Aerocontrol UMS 001, but only with locking monitoring, also available with tilt monitoring. €35 each net, with tilt it should cost €70 net.

(Open, Closed, Tilted)

Why tilted? It usually means double the cost and as previously written by mycraft, the problem of a "ajar door" can also be solved with a single sensor.

Another question: If the window is pried open, the rotary handle does not detect this, or is there a solution here as well?

That is probably the case. Not least because without rotational movement there is no energy to send a signal.

Why tilted? Usually means double the cost and as previously written by mycraft, the problem of a "ajar door" can also be solved with a single sensor.

With the detection for tilt, one could realize that roller shutters move to "slightly open" when windows are tilted or blinds open the slats to allow some ventilation. Or when windows are tilted, the blinds or roller shutters are lowered when it rains so that it doesn't pour inside. Alternatively, this status could also be generated from a combination of an unlocked handle and a closed sash.

In general, I would also rely on wired window contacts, especially because the EnOcean handles do not detect whether a window is being pried open or was possibly not fully closed while the handle was turned to "closed."

With Roto MvS contacts you can easily do it just as you imagine. (Or with others with a similar arrangement/procedure)

Can I install them on any window and terrace door? I have no idea which windows we will get (except for the size and U-value).

As I have read, I then need these 2x to detect tilted windows as well? If cable + slot + component in the control cabinet are added, then I think I will also come into the price range of the window handle.

Do you have to lead every window contact into the control cabinet individually when wiring the contacts? Or can I connect several window contacts to a multi-core cable and then lead this alone into the control cabinet, where the cores are placed on the appropriate terminals?

My better half likes to leave windows open...
