Twisted is not needed, that’s an incorrect message from pymodbus.
I think it should work now

OOOOOOO Hang on… Another reboot might have fixed the issues!
Wow, it worked now! Many thanks @Emilv2!
Dummy question… 
How do I get a state value to be shown in Lovelace, I managed only to show a entity but did’t to show a state of an instance… Tried to search with no lucky…
entity: sensor.sun2000l_5ktl
daily_yield: 11.33
@ligeza, well done, beautiful cards configuration! How did you manage put the “image” of the lines with the inverter, strings, and so on?
Guys, it has been quite a steep learning curve getting to know home assistant, but now i could really need some help. I have followed your instructions and installed the sensor.py (not async), init.py and manifest.json in the folder config/custom_components/huawei_solar/.
I also added to the configuration.yaml:
sensor:
- platform: huawei_solar
host: '192.168.8.3'
I also added the connection to the SUN2000 internal wifi (192.168.8.3) to home assistant via the USB method. When i check with nmcli (on SSH & Web Terminal) using “nmcli con show” i can see i’m both connected to my ethernet as well as the SUN2000 internal wifi. However my log shows the inverter is not reachable. I tried to ping and result is “disconnected”. What am i missing?
Below the log output:

If you can’t even ping to your inverter the problem is not with Home Assistant but with your network configuration. Maybe @ligeza can help you with how he did this configuration?
What do you mean by:
My inverter default IP is 192.168.8.1 did you change it?
I didn’t setup WiFi upon installation of the Pi so use the method in which I connect a USB stick named “CONFIG” with directory network and a file named “my-network” with below code. (I’m on the road now so not able to give you the exact code, but below my best recollection)
[connection]
id=my-network
uuid=72111c67-4a5d-4d5c-925e-f8ee26efb3c3
type=802-11-wireless
[802-11-wireless]
mode=infrastructure
ssid= SUN2000-HV1990005631
# Uncomment below if your SSID is not broadcasted
#hidden=true

auth-alg=open
key-mgmt=wpa-psk
psk=Changeme
[ipv4]
method=auto
[ipv6]
addr-gen-mode=stable-privacy
method=auto
I don’t have PI, but if I correctly understand you are connected to home network with ethernet cable and with inverter by WiFi. Can you check your network status if Pi is connected correctly?
sudo ip addr show
You should see two ip addresses. One for home network and second for inverter.
Indeed Rafal, I have two connections. One on Ethernet cabled home network and a wlan to inverter WiFi.
Don’t have the nmcli screen print here, but the IP details match the one I got on my iPhone when connected to the SUN WiFi and ran Net Analyzer app. Gateway is at 192.168.8.3 and WiFi is at 192.168.8.3.
From screenshot I see that gateway is 192.168.8.1 so you should use this IP in configuration.
sensor:
- platform: huawei_solar
host: '192.168.8.1'
192.168.8.3 is IP given to your Iphone.
Do anyone experiencing problems after updating to Home Assistant 0.110.1?

I’m not sure what is causing this, I think you can fix it for now by commenting out (adding # in front of it) all the _LOGGER lines.
Whoop whoop! You solved it. Many thanks for your help! I’ve got my sensor set up now as you can see in my pic
. Will start building a dashboard in Lovelace now. Hoping I can mimic yours. Should keep me busy for a while!
Another question: how do you store data long term? As rules in the Netherlands will change in ‘23 (no longer able to net the power bought with the power returned to the network) I probably need to look into hooking up a battery. For this I want to have enough historical data to make a return analysis based on period averages as well as intraday profile of power usage and generation from my panels. So what would be the application best used for building a local database?
