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

Thank you for the information. I just realized that I was completely mistaken in my first reaction. It was not a 17k surcharge but 39k plus or minus the 10k for "standard"? Thus, of course, quite far from the idea in this thread. However, if you only take the "KNX points" from the quote, there are only 14-20 left. However, without cables, so hard to separate. What is included in the sensor section? If I understood correctly, there were about 5 presence detectors?

Here you go! So 10K was the standard I would have had to pay for this trade, but I have subtracted that. I currently have to pay 39K to receive the points I described fully functional. Of course, this includes points that have nothing to do with KNX. The delta to the 10K from the thread starter is thus getting larger... The section includes 32 room controllers/touch sensors; 4 presence detectors and 1 x motion detector in front of the front door

contains 32 room controllers/touch sensors;

So each room gets 2-3 of them installed? If I remember correctly, you mentioned only about 145 m2?

A quick word about room controllers: I’m not a fan of room controllers. Completely unnecessary if you still have a visualization somewhere. The actuator does the control anyway, it takes up wall space, and the programming effort is noticeably higher. Considering that you don’t constantly change the underfloor heating anyway and it really doesn’t matter whether you can read the temperature in every room at any time. On top of that, the Jung room controllers KRM TS D are really terrible to operate.

What should I imagine under such a room controller? Something like the control center from MDT or more like the glass switch or something completely different?

Both. Just take a look at Jung's website. It starts with the simple multi-button switch like MDT and ends with control centers. But they are all called room controllers.

Ok, thanks. I'll take a look. Edit: I haven't looked at the application now. But I don't find it nice. Not ugly. But not nice either. But that's all a matter of taste.
