Constant Battery discharge on 100% SoC

Hello,
I notice that there is a quite constant value for battery discharge (from modbus) when the SoC reaches 100%, while there is enough sun (feed-in). Can anyone explain?
Although the SoC does not reduce, I still wonder where this discharge comes from.
It's around 160-190 W.

UPDATE2:
Finally it works. ser2net was NOT working.

I used "mbusd" on the remote Linux host to relay it as "modbus TCP".
Now the nathanmarlor/foxess_modbus integration detects it properly.

Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response ...

H3 RS485/modbus USB Adapter over LAN

Hi,

I would like to use a rs485/usb adapter connected to the comms port pins 1+2 of H3 to access modbus from HA.

But the HA Foxess modbus Integration seems to require only local USB devices to configure. My USB Adapter is connected on another linux host in the LAN.
Any idea how I can use it ...

Thank you very much for the quick feedback.
I will try upgrading to the latest versions.

What would be your recommendations related to the "Grid pressure"?
