New build - which SmartHome system?

Expensive cables? Expensive actuators? Ugly switches? Interfaces discontinued?

No idea, I wouldn’t know which ones.

Loxone has the tree cable, which is recommended but not mandatory.

Whether the buttons are ugly is debatable, I find the switch battery on the wall ugly...

Well then, back to work and closing knowledge gaps.

As said, nothing known to me. The cables make sense but are not mandatory, KNX cables or network cables also work, however for spots the 24-volt supply line. And I am not aware of which interfaces are supposed to no longer exist?

Loxone has decided to omit the KNX interface previously included in the Miniserver and instead installed a Tree connection, which supports up to 50 devices.

Those who switch to the Miniserver v2 and still want to use KNX should, according to Loxone, switch to the KNX extension, which is currently somewhat expensive at 584.41 € . In addition, only "up to 500 KNX group addresses" are supported. And that is actually a joke, since many somewhat more complex KNX components can individually already have dozens of group addresses.

In the end, Loxone is simply much too expensive.

Simple example:

4-channel dimmer Loxone: 471.78 € (channel price ~ 117.95€)
4-channel dimmer KNX: 258.59 € (channel price ~ 64.65€)

14x actuator Loxone: 355.81 € (channel price ~25.42€)
20x actuator KNX: 348.15 € (channel price ~17.41€)

Yes, and?
But it is still possible, tree makes more sense than integrating a KNX interface for just a few users that was never really certified.

For KNX I need switches and temperature sensors, am I cheaper there than a tree Touch.. For lamps I need actuators plus lamps, am I cheaper there than RGBW spots?

If I install Loxone I actually don’t need KNX.

But I actually don’t know any smart home system that includes KNX except maybe comexio.

As written, for office/commercial use KNX yes
In a private house why.

But everyone has to plan that themselves.

Views can be seen in different ways, KNX certainly has advantages, but for private individuals who are not familiar with the ETS, a programmer is needed for every little thing.
