Need help for SMA Integration

Hi all,
I found today the SMA Solar integration. But I didn’t get it working. I habe a Sunny Home Manager (Version1). With nmap I found that there is an open TCP-Port 80. But I cannot connect with a normal browser. And when I do the configuration in the SAM integration with hostname, user and password I got the anser that he cannot connect. I’m absoluteliy shute that user and password is correct. I tested it wit the Sunny Explorer app.
Do anybody know if the SMA integration is workling with Sunny Home manager Version 1? Or do I have to configure something on my Sunny Home manager?
Thanks in advance,
Harald

Since core-2021.12.10 update, I’m also unable to connect to my SMA Solar inverter. Remove and re-install integration no cure.
