Venetian blinds or roller shutters on the south side of the house?

So the things should automatically go down when the sun comes, but go up again in the wind, for example.

Just as an example, we leave the house in the morning, blinds go down to protect the house from overheating. They also withstand the wind. As soon as we are home again in the afternoon, depending on the light needs, they go up.

I also lower the venetian blinds, but at 10 a.m. a summer thunderstorm comes. The wind sensor gives the command to please go up. At 11 a.m. the thunderstorm is over and the sun is blazing from 11 a.m. to 4 p.m. Now the things have to go down again.

Yes, and? I don't have a wind guard - but I do have a sun guard. The parts that are rail-guided withstand something and are not exposed to the wind. But I can retrofit it.

In theory. Have you ever sat in a somewhat modern office building where this kind of intelligence has already been standard for a while?
- Colleagues get half a heart attack when the exterior blinds start moving as if by ghostly hand
- Bright sun, blinds down, then they go up by themselves again. Why? Maybe the wind, maybe ... who knows. So you get up to counteract
- can be continued indefinitely

What happens if you want to step out the terrace door and the [Raffstore] then automatically goes down? Or you are outside and then the [Raffstore] goes down (each time due to the sun position)?
I don’t know. Because of thoughts like these, I completely removed home automation from the planning. It costs a lot and I couldn’t identify any real added value yet. Just a lot of theory and questionable application in practice.

Well, I don't share that view, as this is by no means complex witchcraft.

I have sensors that prevent the blinds from lowering when the terrace handle is open.

No one is going crazy either, because they only lower once at the appropriate light intensity and then stay there.

Our company's buildings also have automatic blinds – and no one has had a heart attack yet...

The venetian blind is suspended on at least two cords depending on the width of the window. Even if this case occurs, it is still possible to lift the venetian blind up from below in the guides and climb in. Automation is not mandatory for venetian blinds. You can install a sun sensor. You should install a wind sensor.

I also lower the roller shutters, but at 10 am a summer thunderstorm is coming. The wind sensor gives the command, please raise them. At 11 am the thunderstorm is over and the sun is blazing from 11 am to 4 pm. Now the things have to go down again.

Huh? Then the wind sensor just gives the command to lower them again?
