Integration Kostal Plenticore Solar Inverter

[nowairly]

The problem

Seems, that G2 Inverter are not supported. Adding the inverter via IP / password ends with an unexpected error.

@nowairly

Maybe i'm facing the same issue. I have two Plenticore, one of them is G1 and the the second is G2.

G1 is already in HA and i'm not able to add the second one.

SW-Version  2.06.09313
MC-Version  02.06.2080
IOC-Version  02.06.0441
HW-Version  0106

[nowairly]

@deadrabbit87 Same for me, the G1 works fine, G2 is not possible to add.

[erikbadman]

I get the same error and have a Plenticore plus 10 G2.

[erikbadman]

Is the correct way to make changes to the code and run it to add the files in the repo under /config/custom_components/kostal_plenticore ?

[erikbadman]

I have looked a little at this now and it seems the names of settings and data sources has changed. I made a test as per the example in the pykoplenti github repo and used the code from this integration and got the same error. When I changed line 35 in config_flow.py from: values = await client.get_setting_values("scb:network", "Hostname") to: values = await client.get_setting_values("scb:network", "Network:Hostname") it worked

Sorry, i didn't know that, but your plan sounds not wrong.

Great that you have found the issue.

[erikbadman]

I made the changes to get G2 working here: https://github.com/erikbadman/core/tree/kostal-plenticore-g2

I have tested this in my home assistant installation and I can now configure the the integration and get data in to HA. Used this information to add the changes locally: https://developers.home-assistant.io/docs/development_tips#test-core-integration-changes-in-your-production-home-assistant-environment

This will of course make G1 stop working, just made this to get my G2 working for now quickly.

[nowairly]

Just installed your changed file @erikbadman, it works as described :-) G2 is running now, G1 not. Thank you, for your effort! As far as I understood, this solution overrides the core integration with the custom. Is there a way, to use both integrations?

[erikbadman]

@nowairly Yes it overrides the core integration, I think you should be able to use both if you change the name of the custom one. Maybe this could work https://developers.home-assistant.io/blog/2019/04/12/new-integration-structure/

[deadrabbit87]

@erikbadman

Could you please have a look on this issue also?

https://github.com/home-assistant/core/issues/87611

[Th0tti]

I can't add my kostal plenticore g2 to home assistant either.

[nowairly]

As workaround it is possible to override the core integration with the fix of Erikbadman - for a "G2 only" setup.

For the case of a mixed setup with G1 and G2 you can use the fix of Erikbadman to build a custom integration for the G2 inverter. The core integration can be still used for the G1 in this case.

[stegm]

The client also contains a method get_settings which returns all available setting ids. Maybe a better way would be to read these ids first and then chose either "Hostname" or "Network:Hostname" depending on which id is available.

Some of the ids are also used in the Plenticoreclass in module helper.py.

I have looked a little at this now and it seems the names of settings and data sources has changed. I made a test as per the example in the pykoplenti github repo and used the code from this integration and got the same error. When I changed line 35 in config_flow.py from: values = await client.get_setting_values("scb:network", "Hostname") to: values = await client.get_setting_values("scb:network", "Network:Hostname") it worked

[Th0tti]

Does anyone know if the core will be changed by official update in the near future?

[matzefisi]

Same problem here with a (only G2) plenticore setup. And I also hope for the official update ;-)

[deadrabbit87]

Same as me. Official Update would be awesome!

[Th0tti]

@erikbadman Did you create a pull request?

[erikbadman]

@Th0tti I haven't since it's not a proper fix. I will try do to that this weekend if I can find the time

[Th0tti]

Excellent. Thanks very much. As a solution, there could be a drop-down menu when querying the host, or a second integration with G2 inverters could be added.

[erikbadman]

@stegm I have added a check as you suggested and created a PR for this (https://github.com/home-assistant/core/pull/92198)

I have tested it locally and it works with my G2 hardware

[Th0tti]

Nice.

Thank you for contributing. I reviewed your changes, please take a look at it.

[Th0tti]

@stegm When do you think the update will be released. Version 2023.5?
