Smart home control, provider / experiences?

The bus cable simply has to go everywhere, to every outlet you drill... otherwise you’ll regret later that exactly at that one outlet there is no cable, and yet it would be the perfect place for something... and at 30 cents per meter... what are you still thinking about?

Theoretically, you can save the bus cables at the lights... unless you want to do something with RGB/RGBW LEDs at that spot at some point, then I would also lay the bus cable there... of course you can also simply run 5x 1.5 to the light and then control everything via DALI, but then that is an additional BUS, whether it is necessary or not, everyone has to decide for themselves...

Run a bus cable star-shaped to every socket and corresponding light, and always run a bus cable to places where extras should go later.

Do you mean every switch box and corresponding light now? Because theoretically there are no corresponding lights for outlets.

Here you say that it doesn’t work. Why do shutters and lights first work conventionally and later via bus not? The decisive thing is that the bus is available on site, right?

I already wrote that in the post because the topology is different... usually with conventional wiring for 3, 4, 5 light points you have one circuit and “interrupt” the phase with the switch. Because of that, junction boxes exist by system design... all of this does not exist with KNX as switching is done directly in the distribution board.

The same goes for shutters... these get one cable = one circuit and are constantly energized... the switches ensure that they go up and down by usually applying the phase to down or up... with KNX you need all 5 wires of each shutter individually in the distribution board (or you rely on KNX drives but that is another topic).

On the power side, you have a tree structure conventionally but a star structure with KNX... but you can hardly make a star out of the tree... that is why I wrote it doesn’t really work...

Of course, you could overwhelm everything with flush-mounted actuators, but that increases the costs again by a factor of 10.

How beginner-friendly do you rate Loxone? I’m not sure if I can manage it. But I don’t really trust the RWE system, I think it’s actually pretty much rubbish...

This claim – that the RWE system is rubbish: is quite bold. I wonder how someone can just claim that? By "believing"?

No: Of course, the RWE-SH cannot keep up with a wired KNX... solution. It’s not supposed to, because it’s not designed for that.

It fulfills the pure basic functions of a HA. It does that well. And reliably. Up to the complete integration of the heating system and (for me: in the future) the solar system.

Comparing a system that costs a few hundred euros with a wired SH solution costing several thousand euros: one can and may do that. Yes. But here you are clearly comparing apples and oranges.

So far, every SH has more or less the reputation of encouraging a playful nature.

I think: SH is useful and everyone can realize their solution according to their demands + budget.

To call things that have been proven to perform as specified "pretty much rubbish" I consider polemic and unprofessional. The system is comparatively affordable and does its job. It has become very mature by now. For people with low demands, who also want to spend little money on something like this, the system is perfectly suitable. One can inform oneself about what it can and cannot do. If these capabilities are not enough, one must choose another system. It’s that simple.

If I hadn’t already had an RWE-SH in the rental apartment before: I wouldn’t even have thought of spending a few thousand euros on more or less pointless toys, laying cables etc. etc. But that too: is everyone’s personal taste.

In the entire neighborhood, nobody (!) has such an SH in any form and everyone already considers me a nutcase with the RWE-SH.

Well, unfortunately, that is not the case, it does not. The relevant forums are full of troubled RWE-SH owners... no one except you claims that the whole system is rubbish... I only wrote that it is sufficient to satisfy the urge to play.

Well, unfortunately it is not like that, it simply isn't. The relevant forums are full of troubled RWE-SH owners... no one except you claims that the whole system is garbage... I only wrote that it is sufficient to satisfy the urge to play

Dear MyCraft!

I have not claimed that it is garbage. I only quoted and referenced that from a previous post.

It may be that some forums are full of troubles (I have deliberately not read the ones about My Gekko and co).

Strangely and oddly enough, I seem to be the only exception: For me, the system works - and always has.

And it does its job so well that my urge to play is satisfied and the real benefit is present. Exactly: basic. Nothing more. Which is because I actually don't need such things at all and am happy that basic functions are provided for little money.

I am well aware of the differences to a high-professional system. I certainly did not just fall out of the sky.

One person needs the Boeing 747, and another is satisfied with the motor glider.

Here are opinions on this:

Gradually, radio modules fail, operation only via button.
Dimmers sometimes turn off by themselves.
Logic functions are very slow.

Problem:
When I came back after being away for 2 days to a fairly cold house, I saw that once again one of the thermostats in the north living room had lost connection, so I wanted to remove the two to be removed from the system and swap in two others from unused rooms. It should have been pretty simple.

I then normally went into the RWE control page, but everything was already weird there, long loading times, and I got kicked out due to long inactivity (which normally happens after hours, not after 2 minutes). I went back in and removed one thermostat, then the trouble started:
- kicked out constantly because I "was inactive for so long."
Sometimes waited a very long time until the control was established, sometimes no control appeared, so I closed the Explorer.
- Occasionally it offered to send the file to RWE, but it didn't work, then the error message "unexpected error" appeared.

etc.

Do you mean every switch box and corresponding light? Because theoretically, there are no corresponding lights for the sockets.

Yes, both end with "box," I just made a mental slip...

The same applies to roller shutters... they get one cable = one circuit and are powered all the time... the switches ensure that the shutters go up or down by usually switching the phase to down or up... With KNX, however, you need all 5 conductors from each roller shutter individually in the distribution board (or you use KNX drives but that's another topic).
On the power side, conventional wiring has a tree structure, while KNX has a star... but you can hardly turn a tree into a star... that's why I said it doesn't really work...

If I have the cables routed in a star shape from the fuse box, would it still work for roller shutters or lights?
Do KNX push buttons actually work as conventional push buttons as long as no logic is programmed - or not at all?
Why do I need 5 conductors from each roller shutter in the distribution board?

Thanks for your answers, they have already helped me a lot
