GVS knx-IP interface (BNIPC-00/00.S)

[Krzysztof13570000001]

When I use this GVS interface with ETS6 program everything works fine.
But I'm trying to use it to work with NodeRED and (I'm completely new to NodeRED) I can't get any result.
I try to turn on the light and get the log to save it to a file and nothing happens. I tested the direct IP address (assigned by the DHCP server to this GVS interface) and the one recommended for router in knx-ultimate manual (224.0.23.12) and it doesn't work either way. In both cases, I see under the knx flow messages: "Auto reconnect" immediately, after that" "Connected On Duty" and after a while "Retry connection". And it keeps happening, it looks like a lack of stable connection to me. It seems to me that it cannot establish a connection correctly. What do you recommend to do to diagnose and solve the problem?

Hi
You should start opening an issue by following the Issue template, because i need all the info requested.
Anyway, if the gvs is a router, you must select Multicast as protocol, otherwise, TunnelUDP (and set the ip address of your gvs).
Then, please, read here the FAQ https://github.com/Supergiovane/node-red-contrib-knx-ultimate/wiki/5.-FAQ-Troubleshoot

Sorry I'm new in NodeRED and in github bute hudge thank you for so quick answer. I used connection as multicast:

I changed IP address (as for router again (224.0.23.12) and in logger connection looks stable:
address 2/1/0 is group address where me room temperature is sended every 60 sec. And now I'm waiting for debug info and text file creation.

Be so koind as to tell me whet informations are important for you.

And when I look into ETS6 monitor I see telegrams with temperature on bus but my debug8 and text file are empty.

Have you tried to set the node in Universal Mode? This way, it will intercept all knx telegrams. Have you also read the FAQ?

[Krzysztof13570000001]

Yes but I only in knx device and I found the following:

I started use your flows two days ago, so I'm completely new. As for now I read about connection, that's why this posts.

[Krzysztof13570000001]

Read about and start first flow - connection with knx bus.

Yes, it’s better to import the ets file, but it’s not mandatory.
At least, you should see the telegrams flowing via the status and the debug node. Please be also sure, not to having any group address filter enabled on your gvs router.
I suggest you to also ask some forums for help, as i can only address bugs and issues. ;-)
You’ll enjoy the node!

[Krzysztof13570000001]

Clear I'll try to contact GVS service because as I understand generally in this case it should work, right?

[Krzysztof13570000001]

And could you tell me what devices are working for sure (Gira, ABB, ...). I have a chance to test other such a interfaces or routers.
Anyway thank you again for so quick contact and suggestions.

You have to disable "KNX Secure".

[Krzysztof13570000001]

In same devices secure is disabled from the beggining:

Some additional tests and it can't switch light (in debug flow I see):

1/7/0 - group address of room light switching
1.10.3 - kxn-IP interface
What does it mean "payload: false"?
