After trying to search some plugin to get the instant power and generated energy of my SMA Sunny Boy inverter 1.5 I've found nothing for domoticz or the solutions were for an inverter with MODBUS or similar.
Then came through a script in the openhab forum that, with the keys I captured for my device, worked fine. So, I've developed my own plugin, a very simple one but it works.
I don't have a github account, so far, then let me put in here just in case you want to use it, or even better, improve it.

- create a directory under the plugin one, like SMA_Sunny_Boy
- copy&paste the code in a plugin.py file
- restart domoticz
- Add the device, introducing the IP and User group password
That's all
I have also updated to 4.10717 and I'm having some crashes, so I don't know if it's due to the plugin, that seems so simple to cause it, or it's the version since I've seen some other experiencing a similar issue.
Comments and improvements are welcome
Thank you
