KNX Timeout

Setup, Configuration and Use Installation

Hello everyone,

I’m still migrating from OH 1.8 to now 4.1 on a Raspberry Pi 3.
Even though everything felt good, I may have had a few similar problems with OH 1.8 in recent years, but they never mattered.
These days, I’ve gone back to the beginning several times just to get a bug-free and clean OH installation.
After I was able to solve some problems, also with the help of this community, I am now faced with the following problem.

Now my logs are “clean” except for this message that pops up every now and then.

==> /var/log/openhab/openhab.log

For background, I have a Weinzierl IP interface 730 and my KNX binding is configured in the following KNX.things file:

KNX.things

It is possible that the following log messages are related to this, because at irregular intervals I get the following log entries.

2024-01-03 23:36:02.929 [WARN ] [nx.internal.client.AbstractKNXClient] - Giving up reading datapoint 2/0/23, the number of maximum retries (3) is reached.

GA: 2/0/… As you can see above, GA 2/0/… Lighting status information.

I have no idea where to start with the troubleshooting, OH or even at the KNX installation?
I am very grateful for any helpful information.

Thank you very much.

I searched a lot (even with google) but untill now I didn’t found something…
Now I hit this thread, what seems very similar…

however, I don’t understand the possible solution…

I’ve got an Weinzierl IP interface 730 also, and my bridge is configrued like this on a standalone Raspi (no docker):

UID: knx:ip:local
label: KNX/IP Gateway
thingTypeUID: knx:ip
configuration:
  useNAT: true
  readRetriesLimit: 3
  ipAddress: 192.168.78.33
  autoReconnectPeriod: 60
  localSourceAddr: 0.0.0
  readingPause: 50
  type: TUNNEL
  portNumber: 3671
  responseTimeout: 10

from what I see, the useNAT is true at my config.
What KNX-address does your Weinzierl have?

4

Hi,

on KNX-Bus: 1.1.255

That’s ok, these are standard Weinzierl information - and the same with mine.

Next up: how’s your configuration for

  1. your actuator with KNX address 1.1.11
  2. your actuatur using the GAs throwing the WARNs:
    ** 2/0/3, 2/0/11, 2/0/22
6

These messages:

[WARN ] [nx.internal.client.AbstractKNXClient] - Giving up reading datapoint 2/0/23, the number of maximum retries (3) is reached.
[WARN ] [nx.internal.client.AbstractKNXClient] - Giving up reading datapoint 2/0/11, the number of maximum retries (3) is reached.
[WARN ] [nx.internal.client.AbstractKNXClient] - Giving up reading datapoint 2/0/22, the number of maximum retries (3) is reached.

are about datapoints, which are set to get read (i.e. < in front of the GA) but aren’t readable.
Please be aware that for successful read requests, there has to be exactly (!) one CO which is configured with

  • the corresponding GA as first (or main) GA
  • at least the Flags set to Communication and Rear (in german Kommunikation and Lesen)

So either correct the configuration in ETS or get rid of the < in front of the GA 2/0/11, 2/0/22 and 2/0/23

Hi Udo,

I did check the ETS Flags an indeed, there have benn missing some “Read” Flags…
We will see if the Log Warnings are gone now…

But there are outhers:

Do you have a hint @Udo_Hartmann what’s wrong?

If I add Channels:after Thing {

It doesn’t change anything…

You simply mixed up two different ways to configure. Either set bridge and thing independent (i.e. you’ll have to set the whole UID and the bridge separately:

Just switch from file-definitions to UI-definitions. There’s nothing missing, on the contrary UI-based configuration offers some more hints and makes sure, there’s no typos.

PS: you don’t have to add the KNX addresses to the things as the Weinzierl 730 doesn’t support router functionality, so it’s kinda useless. You could pack all your GAs to one Thing and still everything works.
Just to be on the safe side and because I can compare OH-config with ETS-config I created a thing for each actuator…

Thank you Udo,

that helps.!!

But let’s be honest, that’s not recognizable from the documentary. :slight_smile:

12

Well, the first option isn’t mentioned in knx context.
However, there are other examples such as mqtt things and channels where this format is used.
Both options are valid for every “bridged” binding :slight_smile:
But for sure either use option one or option two but never option one inside option two…
