How should stair spotlights be switched on?

You think it’s easier in a conventionally wired house? What does the guest do in such a case? No bus, everything conventional, a common installation in new builds nowadays:

The top roller shutter switch is the one all the way to the left or right in the room. The rest goes around in the same order. Try it once and you know how it works.

With the lights, you also know after one click-clack. For the tablet, my father would first have to look for his reading glasses. He doesn’t even have them with him everywhere..

Yes, such stupid switch orgies do exist - I made sure that we don't have any of those and that they are logically arranged - as far as possible.

Ultimately, I don't care what a guest does "wrong" - usually I operate my house and I know how everything works. A guest might mess up, but nobody really thinks sustainably "Wow, annoying - he should have had the bus!"

These are just those constructed things - a sophisticated bus system is great, but conventionally living is not worse for the resident.

And that also applies to you, Grym, you are also constructing something very negative regarding the bus - and it's not about gaining xy seconds of lifetime.

This is not about KNX.

You asked about switches or motion detectors in the stairwell. I answered you: motion detectors and also how to avoid false triggers caused by pets.

This way, you save triple wiring and two-way switches... which then has a positive effect on the total at the bottom right. And all without KNX

Yes, we could do the stair lighting with a motion detector. Not the hallway lighting, because for me it’s part of the comfort that I decide when it turns on.

But about designing. The thing with the reading glasses and the tablet is not so unusual now. Without reading glasses, you’re really lost without conventional switches.

You also have to let go of the tablet, because if the glossy brochures depict the operation of the houses that way, it does not necessarily have to correspond to reality. It is just another way of controlling things and by far not the only one. For quickly turning on the light or raising/lowering the shutters, I don’t need a tablet; that would be a loss of comfort instead of a gain.

For example, in the kitchen I have a wall switch (90x120mm) with 4 rocker switches and 17 functions, which can be triggered manually (without reading glasses). Additionally, as an aid, the display shows every time what is triggered when pressing the button/rocker switch.

Effectively, however, only about 7 are manually triggered sporadically; the rest of the functions are automated to the extent that no intervention is necessary, but the possibility exists. (15 functions are used daily)

So, we have switches in all hallways and on the stairs that activate a relay timer in the utility room. From there, the spotlights are turned on and then automatically switch off after 30 seconds (or longer, adjustable).
