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?

The handle position can also indicate whether a window is slightly ajar but still actually open (for example, if it has been blown shut by the wind). With only window contact sensors, you can no longer check this.
Additionally, querying the handle position can be used for safety-related functions: if the sliding door is closed but the handle is still open, then the roller shutters will not close automatically (this discussion has already taken place here in the forum). Our bus system can precisely tell us the current status of the window. Tilted is recognizable, ajar means open, and only the handle closed means closed. This was implemented using simple reed switches and a status display from MDT or Visu.
Edit: My wife and I just tested this yesterday. The status only switches to "closed" when the handle is fully closed.

I believe avoiding wireless where cables are possible is the only proper approach (new build) 😉
Of course, it’s different in existing buildings. There, you also have to take a pragmatic approach sometimes.

In my experience, wireless is the worst option because the signal can be interrupted by many factors. Systems that use their own wireless network for communication and amplify the signal from one component to the next are much better.So wireless is unreliable, but a "dedicated wireless system, from component to component" is better—you’re recommending a "mesh" network (from component to component), but not with standard wireless (and not with light either, since wireless signals can be disrupted). Yes, I’m familiar with that; the forester Wohlleben calls it the "wood-wide web," which works via glucose-based protocols (= a proprietary system) through fungi. But how do you implement this in a smart home if it’s not a treehouse???https://www.instagram.com/11antgmxde/
