Hello,
I am currently building a turnkey house and have decided to use radio-controlled roller shutter motors. Accordingly, 230 V wiring is being installed to each window. My question is whether it is more practical to have the electrician run a separate cable from the distribution board to each window, or to always branch off somewhere in between. The last time I was on site, I noticed that the electrician seemed to be taking the power supply for the roller shutters from the nearest power outlet. Considering an additional cost of 100 euros for the 230 V installation, that seems quite steep if they only lay about 3 meters (10 feet) of cable. Wouldn’t it be more sensible to install it separately, especially for smart home integration?

No, an important reason is cost, and this applies universally.
I no longer see a reason to use expensive central control systems when everything can be controlled in a decentralized way. I am aware that currently, ZigBee and similar technologies are not yet competitive with BUS systems. But that will change as soon as 5G receiver modules become inexpensive due to mass production…

The large switches on the wall near the devices remain operable. What a relief that with KNX you can connect just about anything you can think of.

Other solutions sooner or later leave us puzzled, and the supposed gain in convenience turns into a curse. Many proprietary solutions with their micro switches and tiny displays designed for traditional house wiring are certainly prone to problems.

And apps need updates, suddenly look different than before, and cause frustration. Simple solutions often have advantages. Exactly, KNX is one of those. No apps if you don’t want them, and no updates required. Yet it remains competitive and leading for decades.

For this reason, I see the various wireless protocols in the smart home sector as a useful supplement, but not as the ultimate solution.
