knxproj import error: ModuleInstance not found for ComObjectInstanceRef

[t3g]

Hi xknx team,

at first I have 2 say: you do an awesome job!!!
Since february, I am not able to import knxproj files any more.
At first, I thought, I did sth. wrong (in ETS), but afterwards, I saw others having problems... But I waited... I tried getting useful error messages, but had no luck.

I have the following setting:
ETS: 6.2.2, HASSOS: 13.1 (Linux VM in Unraid); HA Core: 2024.10.1

NOW, from V 2024.10. on, I can see the following error message:
"ModuleInstance not found for ComObjectInstanceRef self.ref_id='MD-2_M-22_MI-1_O-2-31_R-3' self.text='Kanal E / F: 1 EG-2 Wohnzimmer Raff-beweg' of application M-0083_A-00C0-40-438F_"

Here comes a screenshot, of the ETS communication object bindings:

I also have renamed the knxproj file to *.zip, checked the xml files, but also had no luck to dig into the problem...

At first I thought it has sth. to do with upload limits, nginx and so on...

If you need more Info, like the project file, pls let me know!

Thanks for reporting!
This seems to be the same issue as home-assistant/core#124920
Meanwhile I do already have a project that raises the same error. But haven't had the time to solve it properly.

PS. if you encounter a bug, better report early - we can't fix what we don't know. And there may be ways to get detailed log messages for some cases.

[t3g]

Thanks for the hint, in future I will report earlier!

It is possible that it comes from the output, that is created by the mdt device, like in the other issue. The parsing error is produced in this case with a "MDT AKU-2416.03" with the latest firmware.

[farmio]

Yes, M-0083 is the manufacturer code for MDT.

[t3g]

Now I am a big step ahead: I replaced the AKU (like andynolle did in the other issue) from the catalogue in Version 4.0 with the one that is 4.1. (firmware version on the device itself is 5.6)

And now the import worked!

The main difference, I saw while transferring my bunch of addresses and settings, was this value:
4.0 (integer and string of the unit mixed):

4.1 (integer only; unit behind the input field):

After recreating everything, I deleted all GAs of the "old" device and resetted the channel functions and then, I tried to delete it - but ETS threw an error:

--> I was not able to delete this device and probably there is sth. wrong with it, that breaks your importer.

edit:
If there are no GAs connected, I could change the Application proggram version from 4.0 to 4.1 (this screenshot is from my backup and the old devices' settings with connected GAs - that's why it is grayed out):

Afterwards, I was able to delete it! --> the more and more I think of it, I believe it has nothing to do with your parser...

[farmio]

Well, it would be nice if the parser was resilient enough to cope with whatever those Banana-software companies throw at us 🍌🙃

I have exactly the same problem. I tested it outside of the Home Assistant with current version of the library and got the following exception:

if helpful I can also share the knxproj file, but not here within the issue tracker
