ᐅ Control system for external venetian blinds in new construction

Hello everyone,

My dad (a retired electrician) and I are currently working on the electrical planning for our new build.
We will be installing a total of 12 Venetian blinds with external venetian blinds (raffstores).
Since my dad still has many flush-mounted modules from Merten in his inventory, I would like to use a switch series from Merten.
For controlling the blinds, we are thinking of a simple setup, without KNX, EIB, or similar systems. The wiring should be done with 5x1.5mm² or 5x2.5mm² cables.

Will this work?
How have you set up your blind controls when using conventional electrical wiring?

According to my dad, an electronic flush-mounted blind control module is suitable if you want to install the “control box” right next to the window. If I don’t want to do any programming, a simple rocker switch with arrows and a matching frame should be enough, right?

In the bathroom, where I would like to have a remote control switch, we would additionally need a remote switch plus, correct?
Also, we still need a wind guard, wind sensor interface, and sun-dusk sensor, right?

I hope you can offer some support.

Thanks a lot!

Actually, your dad should be the best person to help you, or am I wrong?

I am interested in the cost of venetian blinds compared to roller shutters.

Yes, that's about it so far; I just wanted to hear how other builders have handled the control system.

Well, the control system isn’t rocket science; there are many different solutions available.

Unfortunately, I have noticed that too. That’s why I wanted to ask here what other homeowners are using and if they would do the same again.
