Nedap Powerrouter -> Integration?

Hello everyone,

We use a powerrouter from Nedap for our photovoltaic system at home.
Nedap is an Austrian company - or rather they were an Austrian company …

There is an online overview where I can see all the important information about the system.

Is there a way to include this data in the HA?
The power router is connected to my home network via RJ45.
There is no local access (assumption).
I am not sure how long the online access will last.

I have no idea how I can start this topic to implement it to my HA or get local access…

Regards
