New build - which SmartHome system?

So what?

And...Loxone costs more money than KNX and can do less... so how can anyone even consider it as an option? Furthermore, the approach of dropping the interface shows where things are heading.

tree makes more sense

Hmm, so a bus wiring makes more sense than what Loxone otherwise offers. In other words, Loxone has finally recognized after years what KNX has been doing for 30 years. Yes, we agree there. Only that I, for example, would immediately rely on a BUS without detours. Why else, it is nonsense and I, for example, have no money to waste.

but for private persons who don’t know ETS, they need a programmer for every little thing.

You definitely don’t need a programmer with KNX. Not at any time. Apparently, you have even less knowledge about it than initially assumed. I can only repeat myself:

Back to work and close the knowledge gaps...

What can Loxone not do that KNX can?
Tree wiring is the same procedure as KNX wiring
And KNX also has to be programmed with the ETS.

Strangely, Merten, Jung, Busch Jäger also offer their own systems. There must be a reason for that too.

How big does a private home have to be for me to need 500 group addresses?

How big does a private home have to be for me to need 500 group addresses

The reason is simple -> making money with "klickibunti"

Current status for us (at about 300 sqm living space): >1700 group addresses and I'm not finished yet

What can Loxone not do that KNX can?

Simple wiring, fast integration of various systems and manufacturers, interoperability, design and and and... Loxone can't do any of that.

Should I tell you about the Modbus problems and Loxone updates after which functions suddenly disappear? None of that exists with KNX.

Tree wiring is the same procedure as KNX wiring

Yes exactly, it’s a BUS, only with more cables than in KNX, and look, after 10 years they finally realized that a BUS is better after all. So why not do it right from the start? Because the technology is not new.

So as a customer, I ask myself, why should I choose a system that suddenly uses (almost) the same thing another system recognized 30 years ago and has been offering and constantly improving ever since???

Strangely enough, Merten, Jung, Busch Jäger also offer their own systems. There must be a reason for that too.

Strangely enough, Apple has several products for sale. Wouldn't one iPhone model be enough?

That is called market economy and product diversification. That’s how you gain new customers or keep old ones by offering them something new.

Why with more cables? 4 wires, I also have those in the KNX cable. The 2 1.5mm² are only needed for the spots, they always require power whether Dali, KNX, or Tree. 500 group addresses are enough, either I do Loxone or KNX, mixing both is actually not sensible, and for a few actuators they are actually sufficient. Or if someone really wants KNX mice piano.

How big does a house have to be for me to need 500 group addresses

I just felt like writing. I currently have 928 GAs in the ETS. To answer your question: we have ~190m². This is not meant to sound arrogant, on the contrary. It just shows that the 500 GAs from Loxone are a bad joke. I live about an hour by car from the Loxone headquarters. Because of the local connection, I was initially focused on Loxone as well. But here I can only agree with others: there is no reason for it when there is an alternative with KNX that is superior in almost all respects. How do you integrate a ventilation system into Loxone? An air conditioner? Sonos? Philips Hue? With KNX there are gateways for all those things. If manufacturer X goes insolvent or loses interest in KNX, then I use manufacturer Y or Z or whatever. €: I'll just guess: you chose Loxone for your home?
