2 WiFi-Cards and 2 Inverters

[Qerox3]

Hello, im running 1 10KTL and 1 4KTL, both are installed by a company so i can't change or even see any modbus settings.

Connecting to the 10KTL Wifi with Modbus 0 gets me the 10KTL Data, Battery Data and Smart-Meter Data
Connecting to the 4KTL Wifi with Modbus 0 gets me the 4KTL Data
Connecting to the SDongle with Modbus 1 gets me the 4 KTL Data

Trying out ID 0,X (other IDs) didn't work.

So the only idea left was to add another WiFi-Card (cheap Wifi USB Stick) to the Pi and let the internal wifi connect to inverter 1 and the wifi stick to inverter 2. But, seems like because of the IP configuration which makes sense because the wifi-card being the client and the inverters being the router, it also doesn't work.

Maybe someone more HASS/Linux/Huawei/Network experienced knows a workaround for this issue?

Those are the Auto assigned IPs, switching to a static gateway IP doesnt work.

Hi,

two docker container could be a solution.
A good start to do that is maybe this: https://github.com/fgg89/docker-ap/wiki/Container-access-to-wireless-network-interface

Or using network namespaces like this one: https://blogs.igalia.com/dpino/2016/04/10/network-namespaces/

I have a similar solution: Easy Fix change the IP range for one of the inverters

I have two inverters

Inverter 1: 192.168.200.XXX
Inverter 2: 192.168.201.XXX

My Home Assistant has two USB WiFi cards, each joined to the AP of one Inverter.

this way was able to load this integration twice with two different IPs

How do you change the IP range of the inverters?

[Kugelfang666]

@annoyedineedausername if you log into the inverter with the local AP using the Fusion Solar App you can configure its DHCP

Don't you need an installer account to log in to the access point? I can connect with my phone to the AP, but I only have a user account for fusion, if I open the app, it just says it can't connect as I'm not connected to the internet

I think your confusing some things

You can join the local WiFi AP with a pre shared key (check the sticker on the inverter)

Once you are in you need to authenticate either as installer or owner.

I don't remember on detail but I think DHCP could be changed even as owner

I managed to log in to the access point, but as a user couldn't see any way to change the DHCP settings. I suspect I need to be an installer to change those settings, but will see if I can find anything.
