Question Regarding Group Address Wildcards and Gateway Connections in KNX Ultimate

[vantech14]

Hi,

First of all, great work on KNX Ultimate — it’s a fantastic integration.

I have a question regarding the use of 3-level group addresses in the main KNX DEVICE node. When listening for scene recalls from the KNX bus, I’ve noticed that the node seems to allow only a single Group Address (e.g. 1/1/4) to be monitored per instance.

Is there support for wildcard addressing, such as 1//, to monitor multiple group addresses within a main group?
If not, and I need to create a separate node per Group Address, does KNX Ultimate share a single tunnel connection to the KNX/IP interface across all nodes — or does each KNX DEVICE node create its own KNXnet/IP tunnel? Does the latter cause any issue with multiple nodes and is there a physical maximum?

Thanks in advance, and appreciate all your work on this project.

Hi
thanks for the interest in KNX ULtimate.
Currently, no wildcards are supported, but you can either copy/paste the nodes, or maybe use the KNX Device node with the Universal mode group address:

You can use as many nodes as you want. They shares a single KNX connection to the gateway.

PS: in the Wiki and in my youtube channel, you can find any info regarding the "Universal mode".

Thanks for this. I tried the universal mode and this works, however for every group I just get a payload of scene 1,2,3,4 for the scene recall. The payload does not contain the group, e.g., group 1.1.2 scene 2.

Maybe I'm missing something?

I'm, currently on holiday, i'm unable to ditch into that, but the node outputs all data you need. Use a debug node set to show the entire msg, instead of only the payload.

Cool thanks, I'll check. I'm also on vacation but working some hours each day. Enjoy your holidays.
