I’m not sure, is the script actually requesting that value?
How do you connect to the CLI? I have my RPi connected to the WiFi of the inverter but I have no clue how to connect to the modbus…
Basically this is my schema of connectivity:
Inverter is connected to my home network via wifi, they has the 192.168.1.x ip address.
I installed home assistant on my pi4 on docker with huawei solar script. The command that i launched on the previous screen is from cli of home assistant container.
The question is: why the battery data is not available among the sensor attributes?
After update, (reinstal from custom HACS), inverter data is not show. I check inverter connection:
in configuration.yaml I use:

The soc modbus location is at 37004

Amazing, where did you find it?
Thank you so much.
There’s updated modbus documentation by Huawei not published… you can ask it to huawei support and they will share it.
Hi guys, I’m back I will look at some issues and try to fix them.
@everyone having issues connecting the app and Modbus at the same time when using the dongle, apparently there is a firmware update you can get from Huawei that fixes this: Reading data from Huawei inverter SUN 2000 (3KTL-10KTL) via modbus TCP and RTU - #83 by Rado1 - Tutorials & Examples - openHAB Community

Can you share the source?
This work for me but i don’t find the register value in my document.
I’ve got a SUN2000-KTL6-L1 it connects to my network to upload data and I can access it fine over my network without using its wifi hotspot.
But it seems to run into problems after a while and it stops being able to connect to the inverter until home assistant is restarted.
Also if you restart while it is running ok there is a good chance it will fail to connect after the restart.
Maybe a connection is getting left open and the inverter won’t allow anything else to connect?
The same happens to me during last 1-2 months, while never I saw it previously.
I have a SUN2000L-5KTL WiFi connected to a WiFi repeater positioned close to the inverter.
Make sure you or anyone else is not using the Huawei app. You can only connect one client at a time to the inverter
anyone having issue after 2021.7.2 update?

Hi all, only for update.
I have made the following changes to display the battery status without modbus:
nano /usr/local/lib/python3.8/site-packages/huawei_solar/huawei_solar.py
“battery_status”: RegisterDefinitions(“u16”, “W”, 10, 37004, 1)
nano /homeassistant/config/custom_components/huawei_solar/sensor.py
ATTR_BATTERY_STATUS = “battery_status”
ATTR_BATTERY_STATUS: self._battery_status
self._battery_status = self._inverter.get(“battery_status”).value
nano /homeassistant/config/configuration.yaml
stato_batteria:
friendly_name: “SOC Batteria”
unit_of_measurement: “%”
icon_template: mdi:battery-charging-10
value_template: “{{ state_attr(‘sensor.sun2000_6ktl_l1’, ‘battery_status’) }}”
This is the output:
I released a new version of the library which changes some register names but accidentally made it not alpha so on a reinstall/update you will install the new version. I will release a new version of the custom component that fixes this today or tomorrow. For now you can change the requirements to huawei-solar>=0.1.0,<1.0.0 as a workaround.
Thank you. I do not know that much. Can you provide how to change the requirements?
Edit manifest.json in custom_components/huawei_solar/ and replace "huawei-solar>=0.1.0" with " "huawei-solar>=0.1.0,<1.0.0"`
works for me now. Thank you.
have this setup " huawei-solar>=0.1.0,<1.0.0"`
but on core core-2021.7.3 not working .thanks
hm now all working.thanks
