New semi-detached house - smart home setup with an extra 10,000 EUR?

So that would be 7 K instead of 2 K.

Yeah okay, of course you could calculate it that way, although I wouldn’t know exactly what the mentioned components cost.

That should fit better, but then you have no light switches. :D

Yeah, that’s the point of the exercise, right?

It naturally also depends a bit on the level of equipment, but assume for example that network sockets (duplex) cost around 200 EUR each. You quickly have ten together, which already uses up the 2 K by itself.

Basically correct, but for me the network point is already independent of KNX.
I would have taken network sockets even with "standard" electrics.
Maybe it’s two more now for visualization and distributor connection, but that doesn’t make much difference.

Where is the construction site?
At least 3 separately switchable circuits per room to the distributor. Which are initially laid on terminal blocks and all sockets are initially on continuous power. Later you can rewire as needed.

And of course bus cable in every corner and everywhere you could somehow imagine sensors or actuators (plan so that an expansion would still be possible in 10 years). Don’t forget empty boxes. Laying the bus cable in addition to NYM is really no effort and practically cost-neutral.

In OWL.
Yes, that is on the wish list so far. But I still have to make it more concrete, i.e. where empty boxes and so on should go.
A friend just told his electrician to lay empty conduits and so on properly for future flexibility.
Although it was approved, in the end there was nothing extra. ;-)

Just saying is useless. Only what has been recorded in black and white is valid.

That only calls for an integrator when (obviously) no knowledge and no understanding of such technical topics are present.

It deserves respect when someone buys an ETS and manages to build a proper topology with all features. Now, such an ETS is not exactly cheap, and a basic KNX course for electrical professionals takes a week, just as a thought. Then you basically still know nothing, and experience is also lacking. A good integrator rocks through the topic including the optimal operating concept quite quickly and often has ideas regarding potential savings on the hardware. As a client, I would rather indulge myself with the outdoor facilities before putting myself through that.

Regarding the thread, the 10k: the more I plan, the harder it becomes to stay within that price range. You really have to be good at saying "no, I actually don't need that." You do find a lot of things you'd like to have (prepared), and that makes it expensive.

As a builder, I would rather unleash myself on the outdoor facilities before putting myself through that.

That's probably a matter of taste. I see it more as a hobby and also feel that without a strong interest, one will have little joy in it, because changes on KNX are hardly feasible for the uninterested. Calling an electrician/integrator every time sounds unattractive to me.

Calling an electrician/integrator every time sounds unattractive to me. [/QUOTE] OKI! But I would really be interested to know how it was. I worked for a long time at a manufacturer, and attending these courses at the in-house training center was mandatory. For me, a disaster. However, I met my husband through this job, coincidentally an integrator, and thus solved the problem :) Normally, such a house is set up, lived in, and a change list is created. After that, it should actually be fine, and if not, you fix it quickly via IP. If it is really a hobby for you – great. Despite various certifications as "advanced," I could not do it, and that's exactly what I wanted to make interested people think about before they invest in an ETS or something similar.

In this case, the call for the SI would come up, but you already have it in hand. ;)
