Does anyone have a SGxxRT inverter with a working YAML file?

[Jogi83]

Hello there.
I have a SH10RT and a SG15RT. Works great with the SH10RT. So I created a second YAML file, to be able to read at least a few basic values from the SG15RT. The connection works, but I get values that are not plausible. I know that the Register-Addresses are different and I tried to find the right ones, using the Communication Protocol of PV Grid-Connected String Inverters_V1.1.37_EN.pdf.

However, I'm a total noob. Some values are spread across two registers and I don't know how to put them together. And i haven't really figured out what u need for the different Data-Types. f.E.: when you have to use a "Swap: Word" and when not.
Does anyone have an SG-Inverter and can post the adapted YAML, so I could get a "Cheatsheet"? :-)

Thx & Greetings

PS: Thanks mkaiser for your Work so far. Works really well with the SH.

For the values spread across two registers, you would put uint16. Basically what it says in the communication protocol. For a value spread across four registers uint32, and so on. Also, you have to subtract 1 from every register number.

Thank you a Lot for your Info, that i have to subtract 1 from every register number. Now the Values are more realistic ;-)
