Hello Magnus,
One, Please use the Huawei app topic.
Two, did you try this app already, it supports Huawei as well:
I have the same inverter and it works with the solarEdge & growatt App.

The IP address can be found in the Huawei app, or in your DHCP server overview (this is usually part of your router).
Look for the MAC address of the inverter (this should be printed in the manual, or on the outside of the unit somewhere.)
Can’t find it? Power the inverter off, next, printscreen the DHCP entries.
Now power the inverter back on, and check which MAC / IP has been added to the DHCP entries.
I think I got the IP adress now.
How do I figure out the correct port? I have found a couple of different ports when I look into the details in fusion solar.
..and how about the Device ID? What should be added there?
Here an example of my settings:
For my inverter - the company which installed it had to enable modbus tcp in the settings to be able to connect (https://support.huawei.com/enterprise/en/doc/EDOC1100332847/9412a362/how-do-i-set-the-modbus-tcp-parameter)
This is how my settings look like.
How would you set it up for Homey?

that doesn’t look like the “internal” IP → check your router setup and the connected devices. homey needs to be in the same network. 502 is the default port and if you have only 1 inverter nr 1 should also work
Thanks!
Found everything now and it works great
