Sorry @Mycraft but you can’t make Smart Home appealing to me ;)
I didn’t intend to. You’ve already decided against it. In that case, it’s usually a fight against windmills. But you can still discuss it and exchange opinions.
Regarding wireless: When I think of EnOcean with autonomous window contacts/window handles, switches, sensors, and even valve actuators, I save myself a lot of wiring and batteries.
It’s simply a different approach but basically does the same. However, it has its own pitfalls and often requires more technology than essentially necessary. The biggest disadvantage is appearance and feel. The light switches have already deterred many interested parties.
Yes, everyone has their priorities. For some, nothing but a garage attached to the house suffices, for others a carport is enough. What I sometimes don’t understand is why people from the automation industry sometimes go wireless in new buildings and build a zoo of protocols and devices into the house that then “somehow” work together or side by side.
The problem also seems to be that as a simple user, who perhaps just wants to use the advantages of such a KNX system within a reasonable scope, I apparently can’t “buy” this well-functioning “KNX” because apparently 90% of electricians/service providers don’t really master it (at least that’s how I read it here often) and thus maybe only more expensive, half-hearted stuff would be installed.
The vast majority of regular users can’t grasp the entire spectrum anyway. Sometimes even the people who deal with it daily can’t. There’s simply so much on the market now that you sometimes can’t have an overview of everything, and you basically don’t have time for it either. For that reason, you have to sit down and first explain the rough possibilities to the interested parties. Then inquire about their wishes and needs, and then show what else is possible.
The expensive, half-hearted stuff always has the full potential. Here it is independent of whether it was installed by an apprentice, the master, or the journeyman, maybe with a completely different level of knowledge about the situation and possibilities. Because everything is standardized, any other electrician with “more knowledge” or simply more imagination can adjust the devices in their function exactly as the homeowner desires and also significantly expand the functionality. Even 10 or 20 years later.
An IT-savvy homeowner can even do that easily themselves... and if you’re not IT-savvy, there are even options to adjust parameters to a certain extent via the built-in devices or tablets, etc., even completely without prior knowledge. However, these options must be enabled during the initial commissioning (or sometime later over the years), and you only have to follow the instructions in the manual.
And KNX is a safe bet because it constantly evolves and has high-quality standards. For example, smartphones. 30 years ago when KNX saw the light of day, it was unimaginable that there would be a computer for everyone in their pocket. Nowadays, operating KNX via any smartphone is effectively given.
Since I no longer like wasting endless time with settings, manuals, internet searches, etc., for such things (including underfloor heating + heat pump), I just keep my hands off it and let whatever the craftsman understands and can explain clearly be installed; so probably no KNX etc., since I want to enjoy my home without special studies and without the feeling of having gotten some mediocre but expensive variant,
Completely misunderstood. KNX precisely makes many complicated processes understandable for the average user or pushes them entirely into the background. As a homeowner, you don’t need to struggle with the laws of thermodynamics or calculate ventilation volumes. Let the technology do that. That’s exactly what KNX is meant for.
The homeowner sets their temperatures on a display/phone/tablet, and the rest is done by the technology, which is conducted like an orchestra via KNX. You only have to tell the conductor what should be played, and sometimes he even knows it himself.
What the technology can do is somewhat clear to me, but it’s just not manageable and reliably calculable to purchase for the average home builder.
But all that can be clarified. The average home builder simply doesn’t have time for it; he’s just heard it costs thousands of euros, and he doesn’t have that. But those who dare the adventure are often more than satisfied and enthusiastic in the end, provided everything is done properly.
1. Different temperature perceptions of the residents. Usually, the woman needs higher comfort temperatures.
Yes, but that doesn’t work anyway with underfloor heating.
2. To pick up the topic of automatic shading again: The woman likes it bright, I prefer shade. So a “smart” concept is ruled out. As soon as the sun shines in, the blinds go to horizontal position. Done. My Somfy control takes care of that.
I see nothing smart here. Only a simple if-then condition no matter what. But maybe you are still withholding something.
3. Lighting via PIR is annoying in the rooms. Okay in the hallway, WC, dressing room, but everywhere else I find it disturbing because I don’t always need light or full brightness.
You don’t have to automate everything at all costs. If you want your switch in the bedroom, fine. But hallway, WC, dressing room, and other utility rooms... suddenly you notice that half the house can do entirely without switches.
And yes, certain scenarios have long been invented or thought of. Meaning, depending on how much light is needed, that much is provided. I don’t mean constant light now.
4. That the photovoltaic system dictates when the washing machine starts is also not practical, because I don’t want the laundry freshly washed to rot in the drum while I’m at work.
Yes, well, opinions differ here. One way for one person, another way for another.
I already thought there would be nothing concrete again.
How concrete do you need it? I don’t have a block diagram at hand. The roller shutter simply stays up as long as someone is inside, even if the door closes again due to critters leaving. The motor receives numerous parameters via the bus and then decides to which position it should move. If it’s still shaded, it moves to one of the corresponding positions. If it’s already dark, it goes all the way down. Of course, with certain hysteresis and wait times. It’s not supposed to just constantly move back and forth.
