So your inverter is connected to your home wifi?
The inverter is connected to wifi via a smartdongle. The HA is connected via wifi to the built-in AP in the inverter. I cannot read the information. The FusionSolar Kiosk add-on has not worked for some time, huawei has changed something. I tried like some people to connect via the HA built-in modbus but I get this error.

Could you show your config (modbus and huawei_solar)? Do you have optimizers or battery? Iif you can ping inverter, then must be error in modbus config or something else is connected to internal AP. Do you have HA core or hassio?
The inverter is connected to the dtsuh666-h meter, and the HA that runs on the Rb4 hassio. Itâs a setup:
sensor huawei:
- platform: huawei_solar
host: 192.168.200.1
optimizers: false
battery: false
modbus:
name: solar
type: tcp
host: 192.168.200.1
port: 502
sensor:
- platform: modbus
scan_interval: 14400
registers:
- name: Solar Model name
hub: solar
register: 30000
count: 15
data_type: string
It should be:
sensor:
- platform: huawei_solar
host: '192.168.200.1'
not
sensor huawei:
Settings for modbus integration seems to be OK. But do not use both at the same time. How did you check pings? Did you use Ping (ICMP) - Home Assistant
binary_sensor:
- platform: ping
host: 192.168.200.1
I have a ping from HA to the inverter. When I disconnect the communication between HA and the inverter, I get such a message

I am still struggling with getting this component up and running, I am stuck at trying to bridge the connection between my inverters modbus, over my RPI and to HA. Not very skilled in RPI, Linux and Network so any newbie tips here would be much appreciated.
Another question though: Can this integration give me the individual Voltage and Current of the different PV strings connected to my system? (I have two installed). I want to see how they change over the course of the day individually.
It seems i have found the issue. The time reset issue is from the inverter.
if you turn on the DST timezone or sync the time with ntp, there should be some minutes difference.
atm iâve turn DST timezone off and put my zone +1. So now it will be reset at e.g. 23:01 instead of 00:01
Try pip install huawei_solar
That is great, thanks! Now I only need to figure out how to connect HA through my RPi and on to Modbus on my inverter.

What is your inverter model number?
It is a SUN2000-10KTL-M1 and I have figured out so much that I need to connect to the modbus through the local wifi generated by the inverter. Since I am not running HA anywhere nearby the inverter I need to use a RPi as some kind of bridge between the inverter WiFi and my local LAN. I have my RPi set up with connection to the inverter WiFi and my local LAN. I just need to understand how I should configure the network routing on the RPi.
I have a SUN2000-5KTL-L1 and I used the Solar Fusion app to login and connect it to my wifi.
Then I checked my router to see what its IP address is and set that into HA.
Is your setup different, and why?
Hi guys, yesterday I installed HA on my raspberry pi4 on docker but I canât see the battery data. Do you know why?
AFAIK the different inverters have a bit different setup yes. I have a separate dongle on my inverter that connects to my home wifi and that is used for the Solar Fusion app data but the modbus is only available through the internal wifi setup from the inverter directly. But I will try once more to use the dongle-IP and see if this works.
EDIT: I get the below error when using the dongle-IP for my integration.
âpymodbus.exceptions.ConnectionException: Modbus Error: [Connection] ModbusTcpClient(192.168.10.35:502): Connection unexpectedly closed 0.005144 seconds into read of 8 bytes without response from unit before it closed connectionâ
This seems to be similar to this issue here: Can't get your component to work ¡ Issue #6 ¡ Emilv2/huawei_solar ¡ GitHub
I get the same error if I try to use the add-on while the FusionSolar app is connected to the inverter, but Iâm guessing your inverter is way different, because mine doesnât have a wifi dongle, everything is built in.
Have a look and see if it displayed in the SUN2000 sensor attributes.
is not present among the attributes but if I try from cli:
