Planning electrical systems to be future-proof

If you're happy with it, then it's fine...

There are people who drive a vintage car, would never get into a smart car with tons of assistants, and enjoy life...

However, I would never come up with the idea of calling these people naive or silly.
But that seems to be the usual thing around here. Whoever doesn't want KNX has no clue, right? ;)

So, you want conventional electrics for nostalgic reasons or because of the nice analog switch clusters on the walls? ;)

Otherwise, if it really has to be car comparisons, I would compare conventional electrics more to a 10-20 year old diesel than to a nice vintage car :p

That means, you’d like conventional electrical systems for nostalgic reasons or because of the nice analog clusters of switches on the walls? ;) Otherwise, if it absolutely has to be car comparisons, I would rather compare conventional electrical systems to a 10-20 year old diesel than to a nice vintage car :p

Fine by me. However, the 20-year-old diesel is still running and will probably run longer than my cutting-edge Seat Leon from 2020, where I can no longer control the ventilation if the central control panel fails. That has happened three times already and is really annoying. Or where just the transmission replacement costs me or the leasing provider 5-6,000 EUR, because it’s a 7-speed DSG and not a 5-speed manual for 500 EUR from the "breaker"...

What annoys me is that people here act as if you are an idiot because you don’t consider KNX the holy grail ;)

I automate systems in industry daily... it’s hardly due to lack of competence on my part...

The problem is not necessarily that there must be no alternatives or that they are not desired, but rather that many people simply claim something without being able to substantiate it properly. There are indeed some other good options besides KNX in the home automation world, but unfortunately discussions regularly drift into a direction that is no longer objective because there is simply a complete lack of knowledge about KNX. THAT is regrettable and is criticized, not the fact that there is something else besides KNX. It is always the same wrong "arguments" against KNX and that triggers some people here :)

So you mean, you would like conventional wiring for nostalgic reasons or because of the nice analog switch clusters on the walls? ;)

Otherwise, if it really has to be car comparisons, I would compare conventional wiring more to a 10-20 year old diesel than to a nice vintage car :p

Whereas I would always prefer the 10-year-old diesel to modern cars that control me in every way. It's quite similar with home automation; there are some things I can imagine automating, others not. Unfortunately, you are then actually portrayed as naive or stupid just because you have different ideas.

What annoys me is that people are portrayed as idiots here because they don’t consider KNX the holy grail ;)

If only the holy grail existed ;) I believe it is important to consider many things: knowledge, playfulness, comfort, time, and money.

Some even consider controlling the lighting via motion detectors INSIDE THE HOUSE(!) as smart home. I am already beyond that as a hobbyist.

I am currently in the situation of planning and researching. I have already played with KNX, with Loxone, Dali. I am well versed in open source stuff (Shelly etc), Zigbee, Z-Wave, Home Assistant, and so on.

Everything has advantages and disadvantages. For me, the question is not really which system to choose - but how to get all the systems I can sensibly use to work together.

Not everyone can or wants to do that - then you just go for a system solution.

I have been thinking for a long time about which bus system I want to use - or whether I even need one at all. I cannot say that conclusively yet.

It will hardly be due to a lack of competence on my part...

I still wouldn’t let any orthopedist—no matter how renowned—near my testicles, should I ever need surgery there...
