ᐅ Window handles with position feedback or window sensors?

I am currently planning the implementation of our smart home in the new build. I am still unsure about which basic system to use. However, I am already gathering components to be able to make comparisons.

Since I want to read the status of windows and patio doors (open, closed, tilted), I have researched and come up with the following options:
1. Window handle with integrated EnOcean transmitter (maintenance-free as it does not require batteries)
2. Wired window contacts installed in flush-mounted boxes. The cables would then be routed to the distribution panel.
3. Wireless window contacts with “Tibber”-style radio communication, no cables, no batteries

For me, window handles like those from HOPPE seem ideal. Does anyone have experience with such window handles? Since I do not want a closed patio door to be considered “closed” (the roller shutter should not close and lock me out if the patio door is only latched), wouldn’t only such a handle be suitable, or is it possible to simulate this somehow with window contacts?

Wouldn’t it be “smart” to choose these rotary handles instead of wiring all the windows to the distribution panel (do all contacts need to be wired individually to the panel, or can this be shortened by using multi-core cables)?

One more question:
If the window is forced open, the rotary handle does not detect this, right? Or is there a solution for this as well?

Surface-mounted installation is the option for retrofitting.

This is primarily intended for the basement. Since it is a waterproof basement, I understand that I am not allowed to install boxes or similar items in the concrete walls (otherwise we cannot maintain the waterproofing of the basement).

Yes, that's true, but you still need wiring. Surface-mounted?

Yes, that seems to be the only solution. I am looking for ideas on how to make it as neat as possible.
