Zonneplan + Solis s6 inverter + pylontech battery

Configuration
1

Hi all,

I have a pylontech battery from Zonneplan with a Solis s6 inverter.
The battery is connected to my network through a utp cable. The Solis converter is connected to the battery. I can read the sensors of the battery. But how can I connect the inverter to HA? I have installed the solis-modbus integration, but it asks for a ip adress. I can’t connect a utp cable to the inverter. the only free spot on the inverter is the antenna.

How do I solve this problem?

Thanks.

Sadly the AP-ip address from the installation is not working anymore, so I can’t try it.
