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:
