Blind control for new construction (Many units per switch box)

Ok, understood!

Now I have read that KNX cables should also be laid at a distance from NYM cables.

Is that really the case?
I am having major problems because I am planning a solid wood house and need to configure the installation ducts beforehand. Of course, network cables, antenna, NYM, and KNX all run together in 3x5 cm large slots.

No, you can lay the green cable directly next to/together with [NYM].

OK!!

We will place the roller/shutter boxes in front of the windows, as seen from the outside. This way, we will also bring the power line to the motors via underground cables.
Earlier, I asked whether the motors also need to be operated with KNX cables.
Holes in the exterior walls are always somewhat problematic.
And KNX cables in underground cable sheathing certainly do not exist.

But they do exist, HELUKABEL PE, ERD BUS cables E-BUS ERD...

But an installation conduit system with the green cable inside also works.

Same problem here.
My electricians advised me to do the roller shutters/blinds and some lamps in the living-dining area directly with KNX, and for many other places we initially only lay the wiring (thermostat, lighting, intercoms, ...) so that we can expand later as we want. This keeps the additional costs compared to star wiring well within limits.

If KNX is already in the house, I would also tackle the individual room control with it right away. Instead of the room thermostats, install switches with temperature sensors. You can then also control the lights and blinds with it. It doesn’t make any sense to install normal thermostats now...
