Thank you so much. Had tried that but it didn’t show when i searched only on “SMA”, but when I tried “SMA dev” it showed up. 
Chose “(eg Tripower X)” alternative but can’t get in. Used the ip-adress on my local network. Used the user password for the Tripower X given to me by the installer. It shouldn’t be my login to the SMA account and app right?
The second last field is incorrectly named. Instead of “group”, the user name should be entered there.
The credentials are independent of the app or Sunny Portal
Can you tests your credentials on the inverter?
https://192.168.1.31
I realise I tried that yesterday and it didn’t work. I think I miss the user name information from my installer. I will contact them. Thank you for the support. I will update when I’ve tried with the right user name.
I’ve now got the username from the installer and after some different tests I finally made it through the integration to HA. 
Thank you for the support! I’ll probably come back with more stupid qustions when the sun is up and I can check data.
Have you also tested http://192.168.1.31
What model do you have? Some old models does not support webconnect.
I guess you read my post before I succeded and edited the post. I needed to use https://192.168.1.31 to get it to answer and then I could test my credentials succesfully. Then the addition was straight forward. 
First of all: Thank you for your work!!!
This integration is the only one (partly) working for my new SMA PV-System.
With ha-pysmaplus I successful got access to SMA Sunny Homemanager 2.0 and Sunny Tripower X 25.
Only my Sunny Island 8.0H cannot be integrated (timeout).
Connection over a Browser is working, connection with Sunny Explorer via Speedwire is also successful established and communication is not encrypted.
TCP and UDP Server on Port 502 are ON…
What can I do/how can I help to solve this problem and improve your solution?!
What Version of my integration are you using?
I released 0.2.6 half an hour ago. Please test it with this version.
Please send me the diagnostic information (see first post) and add a link to your post for reference.
E-Mail can be found here: https://littleyoda.github.io/
BTW: For Speedwire Port 9522/UDP is used.
It seems that HACS on my Home-assistant is not finding the pysmaplus repository.
Am i doing something wrong?
You have to use the url:
https://github.com/littleyoda/ha-pysmaplus
Found it. Thank you!
Noob-alert.
Got everything completed and succesful.
But then at the end there is no new device?
Maybe it is because it is the newest range of inverters SunnyBoy Smart energy? (since april 2024)
I have not seen this device before. That could actually be the reason.
Can you please send me the diagnostic information (see first post)?

You got mail 
an update on the integration.
The integration has grown significantly in recent weeks. The integration should now support almost all SMA devices, as a speedwire support had been added.
Four interface types are now supported (more information in the faq):
New Features:
I turned out that the ennexOS-based devices not only provide information about themselves, but also partly about the plant (Plant:1). In my case, the Tripower X even provides the information from the Energy Meter (Sunny Home Manager 2).
It is now supported if several Energy Meters (SHM, EM2) are active in the network.
The update speed of the sensors is now configurable.
For enneox-OS based devices, I have built in an option to set the Power Limit “WMaxOut”.

any chance to get rid of this?
I will remove it in the next version
Any luck on getting this inverter integrated?
Support for the sunny boy smart energy has added.
unfortunately currently without battery information.
If someone could send me the diagnostic information for a sunny boy smart energy system with batteries, I would add it.
Hey thanks. Mine will be connected in the next few days. But it won’t have a battery connected so I can’t help with that.
