How often do you use your roller shutters?

There are several possibilities. Presence generally in/on the house/property, combined with absence in other rooms, combined with presence in the bedroom, combined with presence in the bed. Considering the time of day, position of the sun, and duration of stay in the bed. The example with showering is of course simpler. If you only go to take a shower, the house naturally knows that you are showering -> so you are not sleeping.

Every day, since we don't have children yet and sometimes run naked through the currently still apartment. Not every neighbor has to see that.
Besides, I definitely need the blinds to sleep. When the sun shines in my face at 5 a.m., I totally lose it :D

It was very important to us and we planned it directly into the house. In the long run, I will make them smart with Shellys, like others in this thread, to adjust them according to the position of the sun.

Has anyone here already addressed the topic of burglary? With completely closed blinds, I definitely feel safer when I'm on vacation, etc. That definitely makes a burglary less attractive.

I wanted mechanical shutters myself. They were hardly available. I really had to look to find a company that still offers them. But they were only available for the narrower windows. I much prefer the mechanical shutters. They are faster and more practical. And they don't look ugly from the inside at all. Hardly noticeable. Unfortunately, they were not cheaper.

Forget about normal roller shutters for burglary protection. And if they stay down permanently during the vacation, you might as well hang up a sign saying you are on vacation.

By the way, one point per electric shutter is for the large windows that are often installed today. For floor-to-ceiling and over 2m wide, I imagine it would be quite stressful with a belt.

So a complex interplay of several presence detectors?

Not only presence detectors, that would be too imprecise.
