Smart home / Home automation - Consulting

As several have now confirmed here, Loxone and KNX don't differ much in terms of acquisition costs, etc. so what costs are you talking about?

Phew, I don't even know how to respond to such selective nonsense... You picked out a partial sentence from Uwe, don't know the components, and think that his statement: "Just what I would have needed for all the connections with Loxone extensions" directly makes the whole system more expensive? Oh dear... I have nothing more to say to that!

Well, you see, you do fall back on the KNX protocol after all, so why take the detour via Loxone and then end up with EIB/KNX anyway?

You’d better read the entire paragraph again before writing such nonsense!

Ah yes, exactly... because home automation today already comes with a built-in web server and every roller shutter motor etc. immediately understands what the free service wants from it and what to do with the data.

Oh yes... Sorry, the super great, oh so flexible system needs no server and therefore can't communicate with anything that isn't EIB... My mistake! calm down again, read the texts completely. We now know that you have your opinion, but it no longer has ANYTHING to do with the actual topic here!

Regarding an aspect mentioned above: I am very sure that you definitely cannot save heating costs with home automation. Certainly not if you have underfloor heating with a low flow temperature, or a reasonably insulated building. At most in old buildings where you can shut off one room and then quickly heat it up thanks to an 80-degree flow temperature.

I can confirm that. We have a flow temperature of 31 degrees. If we don't keep the underfloor heating on permanently in the bathrooms, we can't reach a temperature there that allows for showering.

With this low flow temperature, a temperature change only occurs after 24-36 hours. Until three weeks ago, I also couldn't believe it, but unfortunately, that's how it is!

I can confirm that. We have a supply temperature of 31 degrees. If we don't keep the underfloor heating on permanently in the bathrooms, we won't get a temperature there that allows showering.

Therefore, I am also considering whether I should actually spend the money and space on the heating actuators; I need to discuss it again with my GaWaSch.

I am not so familiar with KNX but wouldn't a bus line to the HKV be sufficient for now, just in case? Then you only need to remember to leave a spare line somewhere to be able to measure the temperature.

We lay empty conduits in all HKVs, then we can pull cables through. Actuators that would be suitable for the HKV cost three times as much and I would then need exactly three.

Since otherwise people will complain again that I supposedly haven’t read anything and only pick out individual sentences, I guess I have to quote in full:

First, you only addressed my first partial sentence ("have to buy expensive additionally") and ignored the other part ("or have to tinker").

Second, the HomeServer was only meant as an example, which is why "e.g." was added.

Third: The EibPC with visualization costs over €600 without the IP Gateway, which is also needed, so it is significantly more expensive and ultimately also a tinkering solution with a much higher learning curve for beginners, and Wiregate is not exactly a bargain either and, to my knowledge, mostly just a visualization without major logic functions (otherwise please enlighten me, I am ignorant with devices from yesterday, which I only bought a few months ago).

Have you actually taken a closer look at Loxone or other PLCs?

First:
We never talked about DIY here but about ready-made solutions... that’s why your part was ignored.

Second:
The HomeServer is a bad choice as an example, since it is basically the S-Class and an absolute overkill for the average consumer.

Third, and here I quote myself:

see Wiregate or EibPC to name just two, but there are many many more and every day new ones come along.

Just like you, I only named two examples and added that there are many more fishes in the pond. Just look at the ready-made solutions available for mobile phones alone. The offer is simply huge, starting with completely free software and ending somewhere in the range of the HomeServer.

By the way, here is a quote from Wiregate:

The WireGate Server is a pre-installed multifunction gateway for smart homes. It is specially designed as a gateway between wireless and wired bus systems such as 1-Wire sensor networks, KNX installation bus, Ethernet & Internet as well as serial interfaces like USB, RS232, RS485..
Events and data are stored in simple text files ("logs") and databases and can be easily graphically evaluated with a click. Logic and extensions of functionality can be implemented with plugins. Several dozen ready-made plugins are available for personal use. These can be easily adapted for your own purposes,

New, now in version 1.2. The graphical interface for use in the browser has been extensively revised and greatly simplified. No Linux knowledge is required. A root access is also available for power users.

And yes, I was at the point where you are now about 5 years ago and looked at various solutions including Loxone, so I do know what I’m talking about. And I haven’t stopped but inform myself daily about developments.

Therefore, I’m also considering whether I should actually spend the money and have the space for the heating actuators; I have to talk to my GaWaSch about it again

Don’t bother, it makes no sense and is just money thrown away. There won’t be any control. In a well-built and balanced system, the automation of the heat pump or the boiler, depending on what you have installed, does all the work...

About that nonsense from FreakErn you can really only say:

The title here is:
Home Automation - Consultation

and that’s all I do here...

P.S. I am the personification of calm...
