deleted - Found a solution myself.
Hello, I have a few questions that I hope to get cleared out, thanks in advance.
I have:
Inverter version: V100R001C00SPC140
Dongle version: V100R001C00SPC127
The Dongle is connected to one of my local networks and I am able to talk ICMP to it from the network that my RPI running HA sits on. Is this supposed to enable the the modbus-tcp connection? Or is the required that HA has direct access to the dongleās local network through e.g. a bridge? same question rephrased: Is it possible to communicate over Modbus-tcp using only my local network(that the dongle is connected to)?
When I use ādevice commissioningā from the FusionSolar/SUN2000 app on my iphone I dont see any option to enable ModbusTCP, the only setting I can do is to change the wifi password of the dongle APs wifi. Is this because my software versions are too new? Or is it the fact that my phone is running iOS? Or both?
If I try to configure the Huawei Solar HACS integration it says connection failed, so either the modbus-tcp just isnāt enabled or I have to to some work on the network side of things, e.g. a bridge. (I currently have no wifi capabilities on the RPI running HA)

Nice guide, Iāve setup dd-wrt on an old netgear router I had.
But something isnāt working right for me.
On the status page I can see the inverter keeps disconnecting, it connects for 2 seconds with good signal strength then disappears from the list and repeat.
The router did get an ip via DHCP in 192.168.200 range ok.
The only thing that really looks different to your screen shots is the inverter connects in legacy mode not HT20.
Maybe it doesnāt play nice with the Netgear wndr3700 in client mode.
Yeah I think it should work (look below).
This is unfortunately a known problem of iPhone applicationā¦ In android there is such option visible, moreover you can set ACL for specific IPs or set it unrestricted. Of course you need newest application (on android).
Maybe you can enable logging in this dd-wrt or login via telnet and see if there is something relevant in the logs/dmesg. I didnāt have such problem so I canāt tell you if this is a router limitation (very unlikely, especially because you are saying that it even successfully obtaining IP address from the inverter) or some different problemā¦ The HT20 mode may not be very relevant I think. The router just matches the mode with the client and it may differ in timeā¦
Make sure that you donāt have some other device which is connecting to this inverter in the same time. Do you maybe have your smartphone in your pocket and is it trying to connect? 
This is not true. I have the option on my iPhone. No problem.
I just had my installer company here and they were able to change to dongle parameter without issues using an iphone running the FusionSolar app.

Thank you Manio!
Regarding the iOS question, as has been stated further down, it apparently works.
What I do noticed is that the option for manually selecting a firmware version (eg downgrading), isnāt available on the iOS Appā¦
Thatās correct. However, installing firmware versions can be done via the Fusionsolar web interface if you have an installer account.
Hi Frans1,
Is the kiosk mode still working? It doesnāt work for me. I get some errors:

So maybe now it is present. My statement was based on this:

It was present at least the last one and a half month. Thatās the time I have been using the iPhone app to configure my system. But anyways. It is definitely present. Thatās what is important.
Hello Marco,
I stopped using the kiosk (for over 1 year) because the uniek url was changing all the time.
I didnāt look into it since then. Im using the local integration that is more stable, as most of then people in the topic.
Thanks, Iāll use local integration too, but I have to install a router to connect to inverter AP. The ip asigned by my first router dhcp to the inverter donāt answer . If I connect to inverter AP, the gateway ip is 192.168.200.1. What is the best method to connet HA to the inverter?. I donāt have wifi in the HA linux, only ethernet
Regarding RestApi, the new url is https://eu5.fusionsolar.huawei.com/thirdData/getStationRealKpi , but I donāt know what headers should I use, I think it is still a good solution for people who canāt connect to TDP Modbus

Iām looking into it right now
you donāt need a header
https://region04eu5.fusionsolar.huawei.com/rest/pvms/web/kiosk/v1/station-kiosk-file?kk=KIOSKCODE
Example
- platform: command_line
command: curl -s https://region04eu5.fusionsolar.huawei.com/rest/pvms/web/kiosk/v1/station-kiosk-file?kk=YOURTOKEN | python3 -c 'import json,sys;raw=sys.stdin.read();clean=raw.replace(""",r"\"");obj=json.loads(clean);data_obj=json.loads(obj["data"]);print(data_obj["realKpi"]["dailyEnergy"]);'

I updated my GitHub (itās not the efficient code but works)
I hoop it will work for you

Thanks, I Will check. Finally I made te modbus tcp work with wifi USB adapter. I Connect the wifi to inverter AP and I can conect to inverter at 192.168.200.1
Tomorrow I Will compare this two solutions
Yes I checked the phone to be sure it wasnāt connected to the ssid.
Iāve had a look at dmesg but nothing really useful.
You can see the repeated connections happening, but no mention of the disconnects.

Iām going to give another old router a go.
Hi Rafal, how do you get this card? I only get 7 sensors.
I need more data from inverter. For example instant grid exported and instant grid acumulated in watt.
You can use https://github.com/wlcrs/huawei_solar to have more sensors or use template sensor to create entity from SUN2000-3KTL attributes (i think it is Emilv2 integration you are using now). There is no sensor for instant grid exported and instant grid acumulated in watt, but you can read value of power_meter_active_power from smart meter, if itās negative then you are importing energy if itās positive then you are exporting energy.
