ᐅ What type of external venetian blinds (also known as louvered shutters) should be used?

Yes, a few. You can find them with one click on the Roma website. Or you can use the basic drives and connect them to a system of your choice, e.g., Shelly devices or a “proper” system like KNX.

Here I just wanted to know how Hangman solved it. I’m referring to the Somfy solution and wanted to ask lazily if it’s any good. I will open a separate thread about this. I would like to map as much as possible using Apple HomeKit.

Roma doesn’t do this themselves, since you at least need a weather station or another source for the sun’s position or general weather conditions. With some trickery, this can also be done based on geolocation through calculations or web services, but “real” solar data is usually the correct approach. This is typically handled by a smart home system. Roma doesn’t have its own system like Warema.

Interesting, I didn’t know that Warema is so much ahead of Roma here, even though Warema has “felt” like it’s been around for decades. I deliberately left out the control aspect here (since that’s quite logical), although I’m not sure if a weather station is absolutely necessary (unless Warema requires one for the control to charge more). I believe it’s just programming (altitude above sea level, house orientation, etc.) and then it basically runs on a “time-controlled” basis. What would be needed, though, are motors that can be adjusted precisely by angle, and here I’m not sure if the standard motors from Roma are capable of that.

Uh, ahem, our cleaning routine currently is to close the blinds during heavy rain and just rely on nature’s power 😉 So far, this has been enough, especially since they’re mostly up anyway (we’ve only been living in the house for a year). Two months ago, I tried wiping the closed slats on one window as an experiment, but you have to be gentle because they’re obviously not as sturdy as roller shutter panels. The overlapping of the slats still helps – for a perfectly spotless finish, you’d probably need something like a brush attachment on a garden hose or similar.

We don’t have a smart home system, but the builder kindly equipped them with radio motors and gave us a Somfy Tahoma box with three light sensors and a wind guard. The blinds themselves can be finely adjusted, so automatic tracking is probably possible (at least with our motors). I haven’t started using this yet because we haven’t really missed it so far: in summer, it’s enough to set the slats horizontally (since the sun is high), and now I might just tilt them three or four clicks down. This can be set as a default with just one button press, which is about a hundred times faster than any ‘smart automation’.

Thanks for your answer! That was quicker than my last reply.

Okay, I’ll have to get into it more—I'll take your comment about “fine adjustment” positively; that should actually be workable! Automatic tracking is really handy, especially if the hardware already supports it and it might even be implemented quite cost-effectively 😎.

One year also means a whole season of pollen—sounds not bad at all from a cleaning perspective 😉. By the way, what color did your blinds have again?

Can you add anything from your experience with a darker color?

Can you maybe add something about your dark color?

The darker color fits the property more stylishly, especially if you now have 7016 (anthracite) windows. I didn’t like the silver ones; they had an office-like feel. Darker colors show dirt a bit more and heat up more :-) but I don’t mind since we also have an active-passive cooling system.

And how do you clean your external blinds?

What do you mean by “they heat up more”? Can you feel it inside when the windows are closed 😱? Are they integrated into any smart home system?

We have window frames in RAL7015 (a shade slightly lighter than the common 7016 Anthracite). Other elements such as fall protection, balcony railing, and cladding are also finished in this color. However, for the windows, we deliberately chose natural aluminum window sills and gray aluminum venetian blinds. On one hand, a completely dark design seemed too gloomy to me; on the other hand, there are practical reasons such as heat buildup, dirt accumulation, and reflection.

Contrary to my initial concerns about whether this would look too mixed, I am simply thrilled and would definitely do it the same way again. The gray aluminum works really well and visually integrates nicely. For your information, we have a pure white plaster facade.

Okayyyy, that really sounds like a very crazy play of colors 🙂. Could you take a picture of a window (maybe also showing the roller shutter 🙂
