ᐅ Blind Control System for New Construction (Multiple Units per Switch Box)

Hello and good evening!

I am currently planning the electrical installation for our new build. Initially, we did not plan to install any smart home/KNX system.

However, I am now facing an issue due to limited space for the switch layout in the living room. At the living room entrance (kitchen, dining area, and sofa area), the controls for lighting, heating, and blinds all need to be combined on a narrow wall. I would prefer not to have two vertical switch frames side by side, either with four or five switches each.

In total, there are 5 roller shutter units, 1 heating control, and at least 4 lighting circuits to manage. Additionally, there might be some switched power outlets.

The electrical installation in the house will be executed as a star wiring system.

Does anyone have any suggestions for a solution?

Best regards from northern Germany,
Thomas

Why choose a star wiring system if there is no interest in KNX or smart home technology?

Hi there!

We are building a timber house and want to avoid using junction boxes on the wooden walls. Of course, we also want to keep all options open for the future. At the moment, to be honest, KNX is a bit too expensive for us.

Good luck,
Thomas

Have a look at Homematic IP Wired. It achieves the same result but more cost-effectively.

We had the same "problem": 8 venetian blinds in the living-dining room, 7 individual lights, switchable outdoor sockets, awning switches, outdoor lighting, and so on. We distributed all the switches across three different walls, especially since the structural stability of a single wall is compromised when rows of switches are installed there.

Best regards

Hello,

if you are already installing a star topology (who is doing your electrical work? You or your electrician?), then the additional effort for KNX is quite manageable. Actuator for 24 lamps costs 290 Euros, power supply 80 Euros, actuator for 12 blinds 290 Euros, actuator for floor heating for 8 rooms 220 Euros, and switches depending on the type between 35 and 135 Euros each.

Of course, this only works if you have the option to decide what components to include yourself. A standard electrician usually adds about twice that amount to the total...

It’s not cheaper with Homematic either. The problem with the "expensive KNX" is that people keep adding more and more: "I also want this," "and that," and so on...
