ᐅ Best overall smart home system

But on a different note... @TaiiTvv isn’t possibly related to @Taitv789 (and a few others), is he? 😉

No idea if he is Taitv789, but in the submitted floor plan, he is the semi-detached partner of Pacc666. 😉

This must be an extremely smart home–oriented community.

- Glass switch? Well, if you like it. I know they are popular, but mainly because of the price.

I actually don’t find them that bad visually, and the price is especially attractive at the beginning.

Weather station, yes, having one is necessary; usually you can’t really talk about any kind of automation without it (eyes and ears).

Yes, a weather station was mandatory for us as well, mainly to control shading effectively or to lower the roller shutters at night or when windows are open/when away.
There is probably a lot more possible.

Mycraft schrieb:

Underfloor heating, again manually controlled? Ideally, it should regulate itself without external intervention, certainly not by a manual switch.

The underfloor heating is supposed to regulate itself automatically; I only imagined being able to change the target temperature using the glass switch.
Our new development will be fully connected to district heating (so no separate heating system in the basement).

What do you mean by integrating it? For lighting, most people only consider on/off or maybe dimming, and that mostly by switch presses, so conventional systems would work just as well.

Are my expectations too low for KNX to be worthwhile in our case?

I’ve envisioned the following automations:
Automatic shading in summer
Automatic roller shutters, e.g. at sunset or when a certain lux level is dropped, with lockout protection for the terrace (which only works with window sensors)
Scenes like cinema mode, where certain lights turn on and the roller shutters lower by a certain percentage
Controlling stairway and hallway lighting without switches, using motion detectors
But honestly, when it comes to everything based on motion detectors, I can’t quite imagine it yet without experience.

You would need to look closely at how the system is ultimately designed. Even with district heating, there is relatively little to control in modern houses.

Contrary to common belief—expensive, luxury, etc.—KNX is always worthwhile, even in a 20 square meter (215 square feet) studio apartment.

Automatic shading in summer

This is generally strongly recommended, with or without KNX.

Automatic roller shutters, for example at sunset or when a certain lux level is not reached, with lock-out protection for the terrace (which only works with window sensors)

There’s even much more possible.

TaiiTvv schrieb:

Controlling lighting in the stairwell and hallway without light switches (using presence detectors)

Then consider: human-centric lighting, for example when going to the toilet at night. Or nowadays quite common tunable white (CCT) lighting. In general, different lighting colors for different times and activities.

Not everything needs to. But definitely in the places you spend the most time and all the passage areas.

Should the underfloor heating then be integrated into the KNX system at all?
In our standard setup, we get an ERR (room temperature controller) for each room (which I believe is mandatory for KFW55).

Mycraft schrieb:

Can you give some examples? I probably don’t yet know the full potential of KNX.

Mycraft schrieb:

Not everything has to be controlled. But the rooms where you spend most of your time and all the hallways.

How can you configure the system so that the lights always turn on automatically as desired? It always depends on the situation and is often different and individual—I can’t really imagine a logic that can cover that.

By default, we get an ERR for each room (which I believe is even mandatory for KFW55).

ERRs are not necessarily an advantage 😉
If possible and if there is still time, you should even try to be exempted from them....

I personally wonder about that as well.
Aside from the fact that I couldn’t afford KNX in my house, automated lighting control is the last thing I miss. At least in a home. In my case, no meaningful automation can be implemented because depending on the situation and mood, I want to decide for myself whether I need light or prefer to walk in the dark.
The same goes for the roller shutter control, which in my case is indeed “smart” connected, but I still don’t set fixed times because we prefer to control it independently and as needed. At least when it comes to timing; it’s different for shading and dependencies on outdoor temperatures, for example....
