Thanks so much for the file 🙂 Now I have another question: The IP address needs to be adjusted. Which IP address should be entered for the inverter or the Spacelynk? The question also concerns the group address: which one does this affect?

Hello Pascal!

to "Which IP address should be entered for the inverter or the Spacelynk?"
The one of the inverter. The spaceLYnk needs to find the Inverter within the network.

to "The question also concerns the group address: which one does this affect?"

This depends on what you want to do with it. Or what kind of information the inverter provides are interesting for you.
In case you have a 4" Mini Touch then you are may interested only in the Energy-Values.
In case you are using the Wiser KNX App then you may want to see the energy flow.
In this case you need to link also the Power-Value with a dedicated group address.
In case you want to see the status of the inverter you need to link also this group address.

So it is pretty up to you or the requests of the project on what kind of group addresses needs to be linked.

One hint in case of group addresses ... please use virtual group addresses for values which does not need to be sent on the KNX-Side. Background, when you sent e.g. the powervalue on the KNX-Bus and there is no KNX-Device which acknowledge this telegram the you get useless telegram repeats on the bus.
