ᐅ Which Sensors for What? Inspiration

Hello everyone,

we need to start giving the electrician instructions on what to install where and how to configure it.
I could use some guidance on what makes sense where and would like to ask you KNX users how you use it. Which sensors can be used in a basic way (without advanced components, as our electrician can’t handle that, and I will have to do that myself later) for the classic applications?

I am mainly interested in the following:

1. Presence detectors (PD)
2. Motion sensors (MS)
3. Switched sockets/outlets

Closed -> Reed switches the contacts
I mean the window. Is the window closed = just pushed/shut, or is it locked = handle turned/tilt lever folded?

I was also referring to the window. If the window is locked, the reed switch registers = 1, otherwise 0. The reed contacts are from Siegenia, model UMS001.

Great, we’ll get the series as well, but unfortunately, I don’t know whether it’s 001, 002, 003, or whichever one.

Did I understand correctly that one of the two contacts in the window activates a locking bolt? In other words, does this mean it also needs to be installed accordingly?

Shouldn’t the window manufacturer be the one to answer all this? I don’t order a car and then discuss in forums where the engine should be placed.

Here, I’m just assuming that the "1" only appears when the mushroom heads pull the sash firmly into the seal. To detect the correct locking, the contact should be installed on the movable part of the locking mechanism, and the counterpart should be on the frame at the position reached by the contact when the window is closed and properly locked.

Yeah, they probably should. But accessibility and the involvement of the trades can make that difficult. Sorry for asking how you solved it. I thought it was clear that I understand the issue, and it was also confirmed that it can be a problem. My actual question is, how do you handle it? Essentially, anyone with automatic shading and reed switches has to find a solution for this. My question is: what’s your solution? If your solution is that the window detects LOCKED and not just CLOSED, then that’s an answer. If your solution is just not to close the window, that’s also a solution. Maybe you have other solutions as well. I have no idea. That’s why I’m asking. Agreed?

I haven’t encountered this as a problem in recent years. So far, I have door open → shutter does nothing, and that only applies to one door.
At the moment, for this non-existent problem, I’m thinking more about presence detection on the terrace / outside, where you could also integrate music, lighting, irrigation, and possibly a robot. But I don’t have a proper solution yet.

Damn, someone actually read my post after all

I’ve mentioned this before: Window open (not tilted, not ajar, nothing else): blind locked. Window tilted with the blind down and slats closed: slats open. If someone locks the window from the inside, blind unlocked. That’s all there is to it.
