The GUI of Home Assistant is very cool, but it fails at the KNX integration, as there is no automated import workflow for devices and group addresses. Also you cannot write directly to KNX but need to use Node-RED or some other tool to connect logic from Home Assistant with KNX.
But then you can even use Node-RED alone, as Node-RED can also interface with KNX.
Overall a Homeserver 4 offers much more KNX functionality.

HI.. as far as I know node red is just a js library, how does it interface with KNX? In my case I have the BAOS that acts as a bridge ..

What I’d like to do but I don’t have time, would be to create a device (ARDUINO or similar) that is directly connected to the BUS as if it were any other DEVICE, that can be programmed like a controller.. so as to have the boot speed advantage (a few seconds and not minutes like a server) and to overcome the limit of ridiculous and convoluted settings that you have with ETS..

Basically I would have a device that would go against the KNX logic a bit, as I would no longer have the independence of the single device, but it would be a completely different thing, with infinite advantages..

I thought ABB was the best, I bought 5 fancoil modules, in the end they don’t include the fact of not starting the fancoil fan if the water temperature is not yet hot, absurd (ABB don’t they reply to the email.)

Did I say something wrong?

Node-RED <> node.js
Node-RED is a graphical logic software, that has alot of plugins and also some KNX plugins. The KNX plugin communicates with the IP router/interface to exchange data with the bus, no BAOS needed.
There are alot of different projects to build own KNX connected devices, which is not hard to do at all, but these devices don’t integrate with ETS for configuration, as you need an expensive license from KNX.org for that.

Sorry I have no idea about ABB fancoil modules, only regular floorheating here, which is very simple to integrate. I even skipped room contollers and only set the heating temperatures of the different rooms with Homeserver QuadClient, as you do not change this very often at all.
My air conditioning devices don’t have any KNX interfaces but WLAN and are integrated in ioBroker, which is connected to KNX with Node-RED.

I did some research and I found a class for the communication between php and knx, it happens through a simple socket..

So I asked myself a question, what did I get the baos to do? :-|

To do what I want to do, ETS is not needed..

PS: I saw that if you google E#T#S#6 C#R#A#C#K# the page of this forum comes out, this is not good..

Hmm, not sure what you mean.
ETS is for installation only, you don’t use it later to run your KNX.
The KNX router/interface and you BAOS can transfer data from LAN to KNX using some library or with the BAOS by using simple webservices, that need no library at all.

Yes, through the interface I communicate with the bus using the web server, I need the library for data interpretation (DPT), the BAOS at this point could be useless since I can read and write directly, however the fact of being able to create bit groups could be useful..

Hi.. I just wanted to say that I was able to interface knx tunneling with PHP directly without baos, unfortunately I don’t have time now to implement the system (I have to study many things), but in the future I will implement it..
