Is Smarthome KNX automation possible based on the floor plan?

About the push buttons: Have you seen the new MDT push button for around 120 euros? And to quickly go to the kitchen, you don't need a push button. Not even one for operating on the go. You generally don't need one for the light, but of course, in certain situations, it's nicely adjustable via the push buttons.

Regarding the buttons: Have you seen the new MDT button for around 120 euros?

Nice to look at, but it's a pure glass button without haptic feedback, right? So, you really can't operate it without looking? The Berker BIQ look quite nice and, as far as I read, are real rocker switches, meaning you can press and toggle them. But they can't be labeled. So that leaves the Enertex MeTa. From what I have read, those are also real mechanical/haptic buttons and not touch. Plus, you can label them. But the price is around the 500 EUR range. I know, the glass touch things look nice, but in everyday life, a button/switch with haptic feedback is "more comfortable," I suppose.

And to just walk into the kitchen, you don’t need a button. Also not one for operating while passing by. You generally don’t need one for the light, but in certain situations, of course, nicely adjustable via the buttons.

I do need a button. If I run that via PM, then a delay time of at least 15 minutes is recommended in the KNX forum. Then I can still see the kitchen light from the living room for 15 minutes and it will bother me for 15 minutes. So I do need buttons to turn on, complete the task, turn off the button, and then the set light fits as desired again. The main problem is rather the costs, or are there really people who do only light and blinds with KNX and also long-term dispense with window contacts, PMs, VISU, servers, ETS upgrade, weather stations, alarm system-like functions, cameras, integration of doorbell system, occasionally new buttons, heating, ventilation, voice control, etc.? Not just 1-2 things but all these things? And then in the long term, you end up with 20-30k extra cost. Another question, how high are the KNX "start" costs? I need, without having automated anything: - at least ETS 5 Lite - bus power supply - larger control cabinet or KNX cabinet? - interface from PC to bus (is there something via IP and USB?) - anything else?

I don’t find the topic difficult at all. We solved the hallway light problem in such a way that when we enter the house, we operate the light switch. When we use the stairs, you can turn off the light behind you. I would already have a problem with motion sensor lights in the hallway: I don’t want to be on display when someone rings the doorbell. That’s so convenient, I tell you. You have noticed that too. What I find very practical about our system, however, is that when I park my car in the carport late in the evening, I find the front door in the outdoor light of the home, and my sleeping husband isn’t woken up by a light that turns on automatically (somewhere near the couch or even upstairs, near the bedroom). After 3 years, our property is enclosed in such a way that we can still enjoy our beautifully lit garden from inside in the dark with the blinds open. Washing machine, toothbrush, razor, handheld vacuum cleaner: all these are allowed to run or charge in our absence, and we are not limited to specific sockets... But I’m sure that is also possible with KNX?! Please don’t take the little jabs amiss, but sometimes it’s just the case that some people make life more complicated than it is or can be. Unfortunately, I haven’t dealt with the KNX topic yet, but I often read along. Now I spontaneously engaged in a comment... Spontaneously, it may be that today I live what I didn’t live yesterday (go to bed early and watch the sunset from inside, read in the bathtub instead of resting, come home and have a glass of wine with the neighbor before going inside, etc.) I can’t imagine that KNX is made for daily changes, just as I can’t imagine with many acquaintances that their needs are the same every day. Surely some features may be great, but whether the proportionality to the costs is justified, I doubt.

That's exactly what I mean. It never ends. Either you are disciplined and tell yourself "I don't want this mega switch battery in the living room!" and only use KNX for this application. Then you might get by with a few hundred euros more. But if you want this and that ... it apparently never ends. And you are never really done anyway. Whether the switch has to cost 500€, whether you need one in every room. I think you're exaggerating a bit there. The fact is, there are also very ugly switches. Your scenario with going to the kitchen can be handled by the switches with the so-called tap function if I understood that correctly. Look it up. Basically, I agree with you that a simple switch has not only become second nature to you, but also to children (!!!) and your guests. There was a picture here in the thread of a silver/aluminum switch completely without labeling. What is that supposed to be? Nobody will get that without instructions. 4-6 sensor switches and then just want to turn on the light? That's not a help anymore, but work. But: Nobody is forced to install that 550€ part with x integrated sensor buttons everywhere. You can also install completely normal rocker switches. In the living room you might have more buttons, in the children's room just light on/off and blinds up/down. So analog to the normal wiring.

Here is our horrible switch battery - logically arranged, easy for everyone to operate. The lamps controlled there can also be operated and dimmed from two other locations.

Grym, if I were you, I would really leave it alone - honestly.

What are the little lights doing? One is lit at the top right and the other three at the bottom? The two at the bottom are the roller shutter/blind switches? Above them then the RTR?
