ᐅ Roller Shutter Wiring – Smart Home

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?

With wireless systems, it doesn’t really matter. The roller shutters are wired in parallel (unless the electrician is really inexperienced), meaning you can control each branched line or supply cable individually. Wiring directly from the distribution board is also possible. However, if everything is on the same 16A circuit breaker (which I assume based on your description), it doesn’t actually make a difference whether you branch off from the outlet or run the cables from the distribution board (the latter even saves a few meters of cable).

If you are sure that you want to use radio-controlled motors now and forever, then it doesn’t really matter. However, it is better to centralize everything in one place; this way, it is theoretically possible to switch to a different solution later on.

With or without chasing the masonry?

It’s not ideal, but it will work with the radio motors. However, if one breaks, replacing it will be quite a hassle. It would be better if the “Smart Home” system controlled the switches wirelessly, as swapping those is much easier than replacing a roller shutter motor.
What did you pay the extra 100€ (about $110) for? What else did they want to install there? 12V?

A defective motor is a defective motor, regardless of how it is controlled.
