Kostal not working via config file

I cannot get the kostal binding to work via the config files.

I installed the binding by adding kostalinverter to addons.cfg.

Via PaperUI I successfully added the Thing and the Items.

But I want to use the config files.

I deleted the entries in the PaperUI and created a kostal.things with the following content, like described in the Wiki.

Thing kostalpico:kostalpico:inverter [ url="http://pvserver:****@" ]

I also tried this:

Thing kostalpico:kostalpico:inverter [ url="", userName="pvserver", password="*****" ]

The Karaf console and the PaperUI do not list this thing.

I started debugging:

openhab> log:set TRACE org.openhab.binding.kostalinverter

But I get no ERROR in openhab.log.

btw: This is the third out of four bindings I cannot get working via config files.
Really frustrating. :disappointed:

I have this configuration which works without any problem:

Thing kostalinverter:kostalinverter:Piko "PV-Umrichter" @ "Heizung" [url="http://192.168.xx.yy", userName="user", password="pass", refreshInterval=60]

Maybe the documentation isn’t right as the info text at the binding states:

Supported Things
Kostal Inverter


Kostal Inverter

You are right.
It works now with your configuration (kostalinverter:kostalinverter).

I created an issue: https://github.com/openhab/openhab2-addons/issues/1893

Just a question, what is your type of inverter?
I do have an Kostal Piko 8.5, and this one is almost 1 year old.
I have had a lot of problem with the bundle at https://github.com/openhab/openhab2-addons/tree/master/addons/binding/org.openhab.binding.kostalinverter

It was not possible to get it ONLINE in openHAB due to that the bundle doesn’t get the info. in the right syntax.
It seems like the last delivered inverters sends the information in an totally different manner then the older ones.

I have now redesigned the existing bundle, so it’s now possible for me to catch up the data from my kostal and even deliver it to openHAB.
I have tested it for a couple of weeks and it seems like it work as expected. Well, I’'m no professional programmer, but if someone has the same or equal kostal-hw as me, might you test it, and get this new bundle to work maybe even better.

Just let me now!


It’s a Piko 8.3, according to the Webinterface.

I can see that Kostal has different categorys of 8.3 PIKO-Wechselrikter, die bewährte generation and 8.5 ,die neue generation.
Don’t now if there are any differences between them regarding to openHAB, but my version-info is like:

Anyhow, I think that you will have to try with the existing bundle and see if it works, and if it doesn’t, we can try with mine.


Like I said, it is working now. :slight_smile:

and I’m right now sure that I found the reason why mine Kostal doesn’t work with this bundle, even though I use the very same syntax as you are.


I run into the same problem. My Kostal (2x) with V5.44 (bewährte Generation) are not getting online with 2.1 or 2.2 on a Windows VM. I can connect to the via there webUI, but the item line that was working fine with 2.0 is now producing a thing that has a communication error. Is there something changed on the Kostal Binding because of the new Kostal inverter generation and do I have to connect via http or an older binding?


just to be shure, I have not done any changes with this bundle.
The bundle I am relating to earlier in this topic is still just running locally in my very own system. If I manage to make it work as wanted it might some day be finished for public use, but I am really not there yet.

I had to redesign because my Kostal inverter is an PIKO Inverters - the new generation, PIKO Wechselrichter - die neue generation and they have then, for a year ago, a totally different communication due to PIKO Inverters - the proven generation, PIKO Wechselrichter - die bewährte generation.

I am right now in a little hurry, but I will do my best asap to see if I somehow can try to figure out som way for you to check if there is the very same communication for your inverter as to mine in these days. I will remember that you can see differences in the source code.
Try to right-click when you are connected to the webUI and then CTRL+U. I do think that we then can compare our code and maybe then find some useful info, or at least some differences or not.

Regards Örjan


yes I´m in contact with Kostal because of my Apple network and at the beginning this wasn’t´t working because of a not implemented bonjour.
Till this I´m a tester for there software.

The “bewährte Generation” will stay/frozen at 5.44. There will be no updates anymore and Version 6 is not supported anymore on this generation. They had problems with the software on this and had to replace the motherboard at all users who are fast enough to install it before they could revoke it from there website.

So there must be in the future a old and a new binding. The old one can´t be removed because of all old inverters won´t get the new 6 UI structure.



To the topic that the binding wasn’t working in the Windows VM: Thats right. Had to install a Unix VM (CentOS) and install openhab2 new and the binding works like it should.

Or make it backwards compatible with a special configuration option like:


support_old_devices = true

I just think we dont want two binding kostal_old and kostal_new.
Since these devices will be running for many years and properbly not see any update after a few years there will be many more devices in the future that cannot be updated to the latest version.

Maybe the binding will need special support for every major version.


software_version = 5.44
# or
software_version = 6.0
# or
software_version = 7.x

just my 2 cents. :wink:

I have now managed to redesign the bundle for kostal.
The new one is working with the inverters regarding to New Generation, as is the type I have. I have not done any changes to the existing code for the older inverters.

I have done an switch in the code so it’s possible to make a change in x.things as below to use the very same bundle for both type’s.
kostalinverter:kostalinverter:inverter [ url=“http://192.168.1.x”,type=“new_generation”]

kostalinverter:kostalinverter:inverter [ url=“http://192.168.1.x”,type=“proven_generation”]

To test if an inverter will remain to the new_generation it’s possible to in an web-browser send the following link to the actual inverter,

and the inverter should then answer as,

which is as I understand an JSON-object.

Then finally an question, I am now trying to make this code to an official bundle as described in “Include the Binding in the Build and the Distro” but I have then turned in to some trouble.
When I do the command mvn clean install I got an answer like:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.24.0:compile (default-compile) on project org.openhab.binding.kostalinverter: Compilation failure: Compilation failure:

I have no faultmessages or whatever in the IDE and the bundle works when I start it from there, and I have even moved it to another openHAB2 system running on an another laptop and everything works as expected.

So I do need som help with this issue!

yesterday we have installed my new PIKO 2.5 MP.
I am running Openhabian with OH2.2
I copied https://github.com/basse04/openHAB-Kostal-Inverter-New-Generation/blob/master/org.openhab.binding.kostal.inverter/target/org.openhab.binding.kostalinverter-2.3.2-SNAPSHOT.jar to my adons folder,
and this Kostal.Things file:

Thing kostalinverter:kostalinverter:inverter [ url="",type="new_generation"]

I also tried with User/PW

Thing kostalinverter:kostalinverter:inverter [ url="",userName="pvserver", password="pvwr",type="new_generation"]

but I don’t get it online :frowning:
I always get Thin Kostal Inverter uninitialized

What is wrong? Does this new binding not work together with OH2.2?



I copied the above linked …2.3.2 Snapshot into the addons folder and for me the overworked binding works perfect. Thanks a lot for it!

However, I have in addition an BYD energy storage connected to the Kostal inverter and from there some additional parameters for charging/discharging the battery, the voltage, the charging level, …

Is there any chance to read in those parameters also?


Thanks, nice that you like it.
I will remember that I had some problems to add more then 23 different ID’s(dxsEntries)
But It should be possible to change some of them.

Today are the following entries:
dxsEntries[0] = “67109120”;
dxsEntries[1] = “251658753”;
dxsEntries[2] = “251658754”;
dxsEntries[3] = “33555202”;
dxsEntries[4] = “33555201”;
dxsEntries[5] = “33555203”;
dxsEntries[6] = “33555458”;
dxsEntries[7] = “33555457”;
dxsEntries[8] = “33555459”;
dxsEntries[9] = “33555714”;
dxsEntries[10] = “33555713”;
dxsEntries[11] = “33555715”;
dxsEntries[12] = “67109378”;
dxsEntries[13] = “67109377”;
dxsEntries[14] = “67109379”;
dxsEntries[15] = “67109634”;
dxsEntries[16] = “67109633”;
dxsEntries[17] = “67109635”;
dxsEntries[18] = “67109890”;
dxsEntries[19] = “67109889”;
dxsEntries[20] = “67109891”;
dxsEntries[21] = “16780032”;
dxsEntries[22] = “251658496”;

If you will try to catch the different values from your inverter, you can do as:

and then just change the dxsEntries as you like from below.

I myself does not have any battery so if you test and let me know if it works as expected.
And if it does, maybe we can switch some entries to the ones that are more needed.

Below is a list with different dxsEntries that as I suppose, it will be possible to use.

Hi Basse,

Thanks for sharing this interesting overview. All queries I tested worked very well and were correct.

However, it seems that I´m interested in quite different values. I would like to read out the following parameters:

  • 16874 Charge 33556229
  • 16876 Current 33556238
  • 16878 CurrentDir 33556230
  • 16882 Temperature 33556227
  • 16892 GridOutputPower 67109120 AC Power, TD = 4
  • 16924 AktHomeConsumptionSolar 83886336
  • 16926 AktHomeConsumptionBat 83886592
  • 16928 AktHomeConsumptionGrid 83886848
  • 16992 dcPowerPV 33556736
  • 17000 batStateOfCharge 16780032 Solar Status, TD = 13
  • 17593 Yield 251658754 Solar Energy Day, TD = 10.
  • 17595 HomeConsumption 251659010
  • 17597 OwnConsumption 251659266
  • 17599 OwnConsRate 251659278
  • 17601 AutonomyDegree 251659279
  • 17623 Yield 251658753 Solar Total Energy, TD = 7.
  • 17625 OperatingTime 251658496
  • 17627 HomeConsumption 251659009
  • 17629 OwnConsumption 251659265
  • 17631 OwnConsRate 251659280
  • 17633 AutonomyDegree 251659281

Are the parameters hardcoded which can be read by the binding or is it possible to change a reference table by myself to get it out?

With best regards,

They are today hardcoded, but to have them configureable from an config-file is in my todolist, and I have right know started to implement this option in the binding.
So I will be back asap, this is not my profession but of course will I do my very best to have it ready soon.
Best Regards Basse

Thank you for the revision of the binding. Now I can also query my Kostal inverters.
Good job! :grin:
