Hello everybody!
I am currently trying to configure my OpenHab (2.5.0). Since I run three Kostal Inverters, I have now installed the current Kostal Binding. After creating a Things file in which I added my three inverters, I receive the error message “Offline - Communication_Error” for all three inverters in Paper UI.fehler_openhab_kostal_191227
When I open one of the things, the message “Status: OFFLINE - COMMUNICATION_ERROR java.lang.IndexOutOfBoundsException: Index: 4, Size: 0” is displayed.


There are no entries in openhab.log.

I have entered the following configuration in the Things file:

Thing kostalinverter:kostalinverter:Piko_Ost "Piko_Ost" @ "EG_Garage" [ url="http://<IP-Address_Inverter1>", userName="<myusername>", password="<mypassword>"]
Thing kostalinverter:kostalinverter:Piko_Sued "Piko_Sued" @ "EG_Garage" [ url="http://<IP-Address_Inverter2>", userName="<myusername>", password="<mypassword>"]
Thing kostalinverter:kostalinverter:Piko_West "Piko_West" @ "EG_Garage" [ url="http://<IP-Address_Inverter3>", userName="<myusername>", password="<mypassword>"]

Access to the Inverter WebGUIs works. Likewise the corresponding access data.

The inverters have WebGUIs in versions 6.11 and 6.20
piko_ost
piko_west
piko_sued

My OpenHab 2.5.0 installation runs on a RaspberryPi 4, 4GB with current Raspbian Lite. I previously upgraded from version 2.4.x. The binding problem described above already existed in this version. I was hoping that this bug was fixed in version 2.5.0.
Since this does not seem to be the case, I wanted to ask the community whether this error is known or whether I have made a configuration error.

I would appreciate your help.

Thanks a lot
Christian

I do not use the binding but here are a few closed issues on github. https://github.com/openhab/openhab-addons/issues?q=is%3Aissue+Kostal+is%3Aclosed

Maybe an issue is similar and you get the fix.:crossed_fingers:

Hi!
As I can see is your inverters of the type like PIKO New Generation, also called second generation right?
The official Kostal Binding is currently build for the first and third generation of Kostal’s inverters.
I have extended it with possibilities to scrape even the second generation inverters, but it’s not yet a part of the official binding, I hope it will be soon.
So neither of these versions have the possibilities to scrape inverters of second generation type yet.

Hello everybody,

Thank you for your feedback.
Yes, the inverters are second generation PIKOs. Basse, is it possible to get a beta of the binding you customized? Would love to try it out.

Kind regards
Christian
