Yes, the problem does not specifically lie with KNX but with the presence detector (which is mostly used with KNX)

Does anyone of you have dogs and KNX??
Would you say that KNX makes sense with dogs at all (especially for lighting control)? I imagine it can also be annoying if the dog constantly triggers the light

But I can hardly judge that since I have not yet lived in a KNX house with a dog

And as already says, dogs don’t need light at night, they manage just fine in the dark

Now you are already using KNX synonymously with automated control. As I said, it can be done differently. Do something else for a day, it's starting to turn into a psychosis for you.
My tip: Leave it alone and don't waste another thought on it. KNX has existed (in principle) for over 30 years. There is a reason why it has not yet established itself in any standard construction performance description for single-family homes. People simply manage perfectly fine without it.
Some people even manage better without it. At least during the planning and construction phase... ;)

That is the third step before the first. All the tools you mentioned are software solutions for the management of the already existing infrastructure. But this must first be created.


In the basic equipment everyone always wants anyway, exactly 0 euros.


There is always enough space for bus cables in the control cabinet. They hardly stand out. In the basic equipment, there are 1-2 pieces for the entire building and the outdoor area.


Well, I would find that annoying. Or rather, consumer automation systems have their bad reputation because they are crookedly programmed or set up and then do not work anytime as the user desires. And let's be honest, why should one put up with half-baked solutions (especially in one’s own new building). For example, I cannot live with that.


No, you have a completely wrong idea. Light control is only one part of the whole. KNX thrives on connecting systems that would otherwise be incompatible and would work alongside or past each other.


I find that super practical. We have two cats and although they are much smaller, I have deliberately dispensed with small animal suppression so that they can trigger the presence detectors.

What concerns do you have about the light? Let it trigger. It’s not a conventional switch on the wall that you have to operate. It also turns off by itself. For the different scenarios (e.g. night or sleeping) there are then also 100 solutions so that it is not triggered after all.


Precisely. Reducing KNX only to light and automatisms is a bit harsh.

thanks for your detailed answer

What would a budget KNX installation look like?

What definitely needs to be done:
-All switches are definitely needed (we like the MDT glass switches)
-All lighting points laid out star-shaped in the basement and connected to the actuators
-All presence detectors must be installed
-Weather station must be installed
-Underfloor heating probably also needs to be done (so that the KNX switches can replace the ERR)

What can be omitted and upgraded later:
-Window sensors can perhaps be solved later with EnOcean (for us it is probably too late, the windows are already ordered) (the electrician appointment has unfortunately been extremely delayed for us)
-Sockets can be installed later as flush-mounted KNX RF or other wireless sockets (we probably don’t need many anyway) (we want to retrofit some sockets that are outside the standard ourselves anyway)

Did I forget anything else?
I want to ask the electrician again what the budget version would cost

I have already understood your concept, but it doesn't give me the possibility to control every socket as I want. Even with 5x1.5, I can only control 3 groups per circuit.

I am aware that you think you don't need that anyway. But I want it ;)

I have never been able to talk a client out of something they absolutely wanted... and some really ended up using it, even though everyone said beforehand "That's nonsense, you will never need that"...

Yes, the drywall installer just told me again "You only build once"...
But since I have to finance my house, at least 70%, the money will eventually run out ;)

Lauterbach once said in a talk show many years ago (roughly, back then still referring to Attila Hildmann, who was somewhat normal in the head at that time):

If I had the money, I would drive a Porsche instead of the small Flinkster I borrow. I drive in the same traffic jam, but maybe I would have more fun.

And that’s how it is. If I took premium everywhere in the house, I wouldn’t have a 5, but an 8 at the front. And I won’t pay that off in my lifetime. And the nicest thing in the end is anyway what you tinkered together yourself... at least for me...
