Zeversolar PV plant with Zevermanager / Cloud integration

Hi, I’m new here.
I have just started my Home Assistant project. But I’ve already successfully integrated my Deye Sun 12k Hybrid and my heating control system.
Now I still need one PV system, I have connected two Zeversolar TLC 15k inverters to the Zevercloud via the Zevermanager.
The ZeverCloud homepage is apparently no longer functional, but I can still log in via the Solplanet app and see my data.
How can I connect this pv system to my HA system?
I have the API Key from zeversolar. But now…
What I have to to next?
Can anyone help me?

Many thanks and best regards!

You should be able to poll the inverters locally: Zeversolar - Home Assistant

With this integration I have to set the IP of the inverter.
But only the Zevermanager is connected to the network directly, the inverters are connected via RS485 to the Zevermanager.
When I set the IP of the Zevermanager this do not work.

Then you probably need to replace the Zevermanager with a bridge to HA and use Modbus RTU. If you are lucky the adresses will be the same as the Modbus TCP ones, but if not you need to reverse engineer it or look if you can still contact them.
