Additional information

I use an ISGplus with Software 12.2.1.222 and an WPL-A 07 HK 230 Premium heating pump.

This heat pump is not listed as "known working device" but should be working like the other known devices. Here´s the compatibilty list from the manufacturer:

Dear @guevara777 , did you solve your issue ?
I'm trying to integrate my HeatPump HPA O-7 CS Premium to Home Assistant, in order to retrieve all the settings available in the ISG.

[guevara777]

I solved it in an other way. I used the Modbus-Integration in Home Assistant.

Stiebel Eltron has good documentation for it -> Link

I shared my configuration with the community here -> Link

[Veaullus]

Thank you for your answer and your sharing, it is very appreciable!
I just have to try and see if it's compatible with my configuration.

I´m able to add the heat-pump via configuration.yaml and it gives me an climate-entity that looks like this:

It seems to have no data and i can find this in the logs:

This seems to be still an active issue.
