Since I am planning to build a house, I am naturally also considering smart home solutions. As this topic is completely new to me, I first need to do some research. I would therefore like to clarify some basic questions and facts before proceeding. I will simply write down my thoughts as if they were facts and would ask you to correct me where I am wrong 🙂
I want to leave KNX or BUS systems aside for now and focus only on wireless solutions, so please do not discuss which makes more sense or is "better." One step at a time; this is purely about understanding :p
There are many different wireless protocols. Open ones like Z-Wave, ZigBee; "semi-open" like eNet; and proprietary ones like Somfy io.
Somfy has the advantage that everything comes from one source and it should be plug and play. The ideal solution for beginners—you simply put together what you need, install it, and it works right away. The big disadvantage, of course, is that you can only integrate Somfy or Somfy-approved sensors and actuators and are dependent on Somfy continuing to develop new products and supporting the current protocol.
eNet is a protocol from a few premium manufacturers, and as such, the devices are quite expensive. Although it is an open protocol, it is supported by only a few providers and products. So it has the same disadvantage as Somfy: limited selection and dependency on a small number of providers.
The open protocols, which are basically standards, have the advantage of many providers. However, this is also the biggest disadvantage because it’s easy to lose oversight, you end up assembling the whole system yourself without it all coming from one source, and there are likely to be significant differences in quality.
Is this roughly correct?

Too simple-minded. Or just not thought through completely. The slots are already there—how else do the 230V come to the sockets and other appliances?For example, operating the windows using window contacts. Here, I see a more practical solution in an "enocean radio frequency handle."

For example, detecting window status using window contacts. I see a more practical solution in an "EnOcean tip rocker switch." However, that only tells you what the handle is doing at the moment, not the actual position of the window. Such a system is suitable at best for comfort automation, but not for monitoring the window’s closed state.

One thing I want to mention: during my research, I noticed that the discussion about "KNX vs wireless" is often very ideological, HansDampf1311 schrieb:
The house will be a wood-frame bungalow, That way, you at least avoid the, let’s say, equally "ideological debate" between sand-lime brick and aerated concrete *LOL*

But that doesn’t tell you the actual position of the window; it only indicates what the handle is currently doing. This is only useful for comfort automations, not for monitoring the locking status.Of course it can. The handle has 3 positions (closed, open, and tilted), whereas a simple contact sensor does not show whether the window is fully open or just tilted 😉untergasse4311 Mar 2021 13:24And what happens to the handle if I force the window open? Exactly, nothing.
