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?

As I said, a turnkey construction with a general contractor... they provide a price for their standard fittings. Then there is a list of additional costs, for example, stairs to the attic, photovoltaic system, underfloor heating, etc. In our standard package, we had roller shutters with manual straps. Of course, I don’t want manual straps in the new house. So I looked into what to do... their additional price for a roller shutter motor was €300 (about $320) per window x 20 windows = an extra €6,000 (about $6,400). I find that quite high. Initially, I wanted to have empty conduit pipes installed for €100 (about $107), but apparently, the contractor guaranteed that these wouldn’t be crushed or blocked during construction. Then I researched radio-controlled motors. Well, I decided to have 230V lines installed everywhere; they charge €100 (about $107) just for the power supply so I can later connect the radio motor myself. Wall switches are planned to be installed on the walls later. Since I’m thinking about the future, I want to know if it would be better for the power supply to come directly from the distribution board. You never know what the future holds.
The mixed price also includes chiseling or cutting with an angle grinder. I work myself in a low-voltage electrical company, but the surcharges are really high.

In my opinion, direct wiring from the control cabinet only makes sense if you plan to install a smart home system with a bus connection. Otherwise, the motor is controlled via a radio module directly on the motor, and the planned routing from an existing 230V circuit is sufficient.

Future-oriented with wireless technology. I see.
You’re laying cables anyway, so what’s the point of the wireless stuff? Just put switches on the wall and that’s it.
A star topology to the distribution panel isn’t future-oriented if the user can’t handle it. Besides, wireless makes it obsolete anyway.
Conceptually, you still have a serious flaw in the system.

hampshire13 Jul 2019 23:44For those planning to grow old in their own home, it is worth taking a closer look at the radio, app, and KNX control logic and panels from the perspective of an elderly person. Large wall switches located near the device remain operable. Other solutions sooner or later present puzzles, and the supposed convenience turns into a burden. We are around 50 years old and have observed this in recent years with my parents-in-law, now with my parents, and within their circle of friends.
Remote controls can be confusing, automations cause stress (why are the blinds going down/up now, is something broken?), and apps require updates, suddenly look different than before, and cause frustration.
Simple solutions often have advantages.

I find the question interesting whether wireless technology is future-proof or not. I even believe that wireless systems will replace wired BUS systems.
Similar developments are already happening in Industry 4.0 regarding automation and data collection in manufacturing environments. The goal is maximum flexibility with as little fixed wiring as possible.
Until then, we simply need 5G.
