Can't connect to the Protoss PE11 - Modbus - wlcrs/huawei_solar

I just tried to connect my inverter with an usb modbus dongle - no success.
Can’t find the usb converter in my hardware.

I tried to establish a connection with the Protoss PE11 - I configured the device as demanded. Can’t find the modbus Server - no network connection to the Protoss.

What is wrong with my HA installation? I a m new to HA so the problem might be me.
Do I need a code prior installation?

Protoss PE 11 ist connected properly to the network/ switch and to the A/B RS485 Arts directly on the inverter.

SDongle is attached to the inverter and connected via lan to the switch/router.

huawei_solar ist in the custom_components.

do i need to paste some code into the configuration.yaml?

tried different id, started several times - I have no idea.

Did you manage to connect Home-Assistant to your Protos PE11?

I managed to connect it via Node-Red but am still struggeling with getting the readouts as an entity in Home-Assistant. :frowning_with_open_mouth:
