ᐅ Control of Multiple Roller Shutters

The data he’s providing is ridiculous. Installing KNX just for a few blinds is completely off-topic and a total waste of money.

A colleague retrofitted Wi-Fi based solutions for the blinds in his apartment. Individually, they work, but the group control doesn’t. There are 8 blinds, and when he tried to raise them all at once centrally, it rarely worked for all; usually, 1-2 blinds didn’t execute the command.
He removed it again and replaced it with something operating at 868 MHz, but I’d need to check again.

Well... if I try to cover 300 square meters (3,229 square feet) with Wi-Fi from a single router without any repeaters, that’s obviously a challenge. But I don’t think many people would do that. Mesh networks are a simple and good solution. Currently, I operate 14 roller shutters over Wi-Fi on three floors and have never had any problems. Of course, you need to ensure comprehensive Wi-Fi coverage, that’s a given. The 2.4 GHz band is especially powerful and stable. The situation is different on 5 GHz, where you need to install more repeaters. But basically, I see no problem for the average user.

Ideally, everything runs on 5 GHz. However, very few people use this frequency because its range is shorter, which naturally increases the need for repeaters and requires basic compatibility of the devices.

With slightly better routers, it is possible to set up multiple networks to separate data-intensive activities like streaming from home automation. In new builds or older homes, streaming, cameras, and similar systems are naturally connected via cables.

Repeaters and mesh networks have no place in new constructions either. However, this seems to be a clash of philosophies.

Why anyone would rely on radio signals in a new build is equally beyond me. Assuming, of course, you want an automated house and not a playhouse.

Is it because of cost and/or the developer?
Unfortunately, not everyone designs their own house.

I don’t understand why anyone would choose wireless technology in a new build. Assuming, of course, that you want an automated home and not a playhouse.

You are probably referring to the presence of a central bus system to connect a wide variety of devices.

I prefer wired solutions as well. However, in our new build, where we wanted to keep the technology to a minimum, wireless made more sense.

I ordered wireless motors from the window manufacturer, finished. For less money, I received the assurance that the control system would be reasonably flexible (groups, sensors if needed, wind sensors, etc.).

During the construction phase, I didn’t want to deal with the more expensive and potentially less flexible central wiring, a dedicated control system just for shading, or the related electrician work.
