KNX node for node-red

[TheMax74]

Hi Bernd,
can you translate this in German for me?

"Update (updates the value without sending any telegram to the KNX BUS)"

Thanks.

[bgumler]

"Update (aktualisiert den Wert ohne ein Telegram auf den KNX Bus zu senden)"

[TheMax74]

Ok, i'm working on it. Please hold on.
I should be able to release a new update in about 1 hour.
Hope.

"Update (aktualisiert den Wert ohne ein Telegram auf den KNX Bus zu senden)"

Hello
v.1.2.5 is out in about 1 hour.

Please refer to this https://github.com/Supergiovane/node...Virtual-Device
And to this https://github.com/Supergiovane/node...es-to-the-node, whether you prefer doing all via a Javascript function node.

msg.event = "Update_NoWrite";
msg.payload = true;
return msg;

[bgumler]

Thanks a lot,

one step closer to the virtual KNX device. Passive status, means only transmitted upon a read now works.

Hello,
I have a question regarding msg.destination which I would like to use to send to the KNX Device node.
First let me say that my node red experiance is not soo big. Therefore I fear that I have made a silly failure.
Can anybody help me and tell me, what I'm doing wrong?

Without using msg.destination my test flow works.

But it seems that the adresses are passed correcctly to the KNX Device nodes.

Node before first inject:
before.jpg

and after inject:
after.jpg
Also the debug 1,2,3 nodes are delivering the right values.

msg.destination.jpg

But the debug node 'Betriebsmodus', 'SollObject' amd 'Korrektur' do not deliver anything.

What is wrong here?

Thx for helping and best regards

Hi Markus
What do you need to achieve?
As far as i can see, you wish to issue a READ request on these 3 Group addresses, right?
Otherwise, what do you wanna achieve?

[megahorst]

Hello,
read on three adresses is right.
Three adresses deliver the parameters for one room.
After the read some cacuilations will follow.
This calculationa have to be done for several rooms.
Therefore I would like to create a sublow out of this flow and would like to pass three adresses into the subflow, let the subflow do the calculations and from there deliver the result into the mainflow.

[TheMax74]

Do you really need that flows variables?
In a range from 0 to 10, what are your javascript programming skills? This helps me to do a sample that you can einfach understand.

[TheMax74]

Please bear in mind, that msg.address doesn't set the address of the node, it only changes it temporarly.
For this reason, they won't emit anyhing, because they stick with 0/0/1
You need to find another approach.
If you have ETS, you can simply import the Group addresses file and you're almost done. Can you do that?

[megahorst]

Do you really need that flows variables?

I think so, but I'm open for other solutrions of course.

In a range from 0 to 10, what are your javascript programming skills?

2-3 ... I'm an old guy. During my studies in the last millenium I have learned Pascal. 😕

[TheOlli]

Oh oh! The next fan of subflows @ nodered
Massimo has not made the best experience with subflows...

[TheMax74]

Nope. Right. I hate subflows. You lost all control over it. Olli, i'm in guru meditation about your gitHub request. Stay tuned.
megahorst, If you have ETS, you can simply import the Group addresses file and you're almost done. Can you do that?

[Alloc]

Hm, I just learned about subflows right now as you guys talked about it. Thought about something like that in the past as this could help clean up some repeated flows but never checked if anything for that existed and was quite happy to read up about them now.

I hate subflows. You lost all control over it.

Mind to go into this a bit more? What's the issue with using them? Of course they might not be a solution for everything, but it felt that they might be good for repeated data processing structures.



PS: Actually reading up a bit about their features I think it would be nice if the environment variables of subflows could be used in KNX nodes, at least for the GA and DPT fields (might already be the case, but it sounds like it's probably not ). This would actually help me clean up my junk a lot

[TheMax74]

Alloc Hi, i really don't wanna talk about subflows. Last time i used it, the nodes in the sublow don't even show their status. They was absolutely not debuggable.
I don't know if with the latest versions, they are better. I don't want to try it.
Yes they can be useful, but honestly, i'm using the "link nodes" instead of subflows in my whole system. I create standard flows with an "input link node" as entry point and an "output link node" as exit point.
