Hi,
I'm running the latest ufficial HA release on my Raspberry Pi5 8GB. Following the instractions of "Paraphraser" part 2 of his gist I'm now able to login to iSolarcloud.
But now I have this error:

Since I was unable to solve this issue I cancged my way.
Now I use WiNet Extractor. Everything works but you need to connect directly to the Sungrow interface over LAN ow WIFI and you get real time data. You need the user and password for the Winet interface. Also the standard user works non need to login as the supervisor
