HansDampf13111 Mar 2021 11:06Since 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?

One thing at a time; this is purely about understanding :pYou should still consider both options. If you initially choose wireless, switching to KNX later won’t be easy—you’ll have to chase channels in the walls. Both wireless and KNX work.I would always prefer an open system. Maybe start with some Shellys for switches and roller shutters. Then upgrade with ioBroker and integrate additional sensors. Just an idea for you.

You should consider both options anyway. If you start with wireless, you can’t just switch to KNX later without some serious wall chasing. Both wireless and KNX work fine. So you mean basic functions with KNX now and if I want more later, just expand with wireless? KNX is not off the table; I’m actually considering both. It’s just not the topic of this thread.

Shelly is initially controlled via Wi-Fi through its own app and can work without Google, Amazon, or Apple, right? From what I understand, ioBroker is something like openHAB/Eclipse SmartHome or mediola (just requiring a bit more tinkering)? What is used as a gateway in that case?
untergasse431 Mar 2021 13:49If only wireless is an option (the discussion would take all day), then take a look at OPUS. It is based on EnOcean technology and comes from a German manufacturer.
Otherwise, I would avoid wireless as much as possible in new buildings. But I didn’t want to start a debate anyway 🙂

So you mean the basic functions via KNX now and if I want more later just extend with wireless? KNX is not off the table, I’m already considering both. Just not the topic of this thread. I mean "either-or." Not both combined, that’s a mess.

Since I am planning to build, I am naturally also considering smart home solutions. Since this topic is completely new to me, I first need to get familiar with it. I could certainly contribute some informed input on this question, but considering your previous posts in this thread, I think it would be irresponsible. So for now, I want to give you just this warning: resist the temptation to use downtime to dive into the details until your basic house-building knowledge has at least metaphorically reached "the basement ceiling"!
Homeowners can sometimes be like expectant fathers thinking they’re already doing postpartum exercises and bottle warming well before the due date.
Regarding your choice of building partner, this aspect is not relevant, as it is typically a matter for specialized planners, and all kinds of systems should be considered independently of construction methods. Just don’t even think about selecting a building partner based on whether they happen to offer some smart home system in their catalog!
