I need to use HA-ModBusProxy

[TMoersch]

Hi,
how can I change the inverters IP in the configuration if needed??
Because I want to run huwaei_solar an evcc parallel, I need to use modbud-proxy to serialize the modbus requests.
The addon is already installed and I want huawei_solar to communicate over the modbud-proxy?

deinstall and reinstall huawei_solar
i´ve done that a few times testing ModBus Proxy

maybe I'am stupid but I dont understand how the communication flow works whith the information I got.....
I know how squid is working ( I know its not the same function here, buts in my head when I think about proxy commincation flow).
You normaly configure your proxy to listen to your local LAN IP adresse an set the listen port.
In this case any apllication that can connect the proxy over IP:port is able to use the proxy, but still need to be informed to do so!!
The application (huawei / evcc) need the configuration which end-device is to call (OK), but they do not have configuration statements which external proxy is to use ???
In huawei_solar I can't define which proxy to use??
How is this working? like export_proxy:... as an environmental variable?
evcc seem to have it's own buildin modbus_proxy. If I follow the configuration info I got, evcc does start something that is listening on port 502. But this seems to be unreachable for huawei_solar, now that I deletet my Huawei installation I cant set them up again because ther is no communcation to the inverter????
In the documentation of modbus-proxy is defined to set the IP to the inverters IP??
I think the listening interface should be something like localhost or local interface IP.
If several independend application are sending the request to proxy IP:port, the proxy can do his job.

I believe I'am totally wrong in my head an can't find any documantation that explains how this should be setup properly.

I realy would love to have the evcc nad huawei_solar parallel in use, communicatiing vie modbus-proxy, this would realy maximise my benefit of having solar and ev.

Here is what AddOn HA-modbus-proxy ist telling me in his log, for me it looks fine.

I am also stuck here. Did not find a way to fix it
