Thank you very much. It's working now.

Hi Massimo,
since version 1.2.39 the watchdog node won't reconnect by sending the msg.connectGateway = true.

I really appreciate your work and keep on rolling!

[TheMax74]

Hi t81s
I'll take a look and revert.

[TheMax74]

Hi t81s
Can you unzip this file into your .node-red/node_modules/node-red-contrib-knx-ultimate/nodes folder and restart node-red?
Please tell me if it works.

[t81s]

TheMax74
it works again!

[TheMax74]

Ok, knx-ultimate@1.2.43 will be out in some minutes.
Cheers.

I've upgraded to 1.2.46 from 1.2.36 today and now my persistent values aren't recognized anymore:

The correct file is here:
/home/pi/.node-red/knxultimatestorage/knxpersistvalues/knxpersist.json

I don't know how this changed...

[TheMax74]

Hi
of you restart nodered, or stop, or deploy, a new file will be created with the persist values.

[zeebee]

A restart and redeploy later everything works again. Never had this before, even after restarts or updates. Anyway, now I know. Thanks!

[TheMax74]

Yes
this is because of a change in handling persistent values. Now, the node value is deleted each time you enter in the configuration window. This is to avoid unwanted false values, in case you change the group address or datapoint of that node.
The migration from old to new behaviour, deleted the old persist file.

Hi Max, I sometimes get error messages on a new system. The KNX Ultimate Node works, however.
Where could the problem be?

Many greetings
Frank

Hi
you may have issues in the link layer.
It seems you’re using a KNX IP interface in tunneling mode.
You should check your switch for uDP storming protection and disable it.
Also, you can try to directly connect nodered with your interface.
This behavior is not normal.

[TheMax74]

PS: also check not to have unused gateway nodes lying around.

No, I don't have any unused gateway nodes.

Yes, I have an IP interface in tunneling mode.
This is plugged into the switch. However, the switch is unmanaged and you cannot adjust anything on it.
Nodered with KNX Ultimate runs on a Raspi. This is located directly in the router.
Could that be the problem?
