@sbf Hi again,
well I really fear that something goes wrong when I try a software update since this is a very old system that is running for almost 14 years now and I would prefer not to touch it. I have read about cases where folks have bricked the inverters and the only answer from SMA was an expensive hardware replacement of the whole inverter.
But I took a closer look to the data and have some questions: In the output it looks like
each block occurs twice (when calling with -d5).

I think I have understood that it always starts with 7E followed by the length (1B in my case - so 27 decimal) - right ? You also mentioned NetID is pos 22 (decimal) - ok - it is 1 in my case.
What does getPacket(2) or getPacket(5) mean ?
To me it looks like byte 16 is the command - right ?
The commands occur in the sequence cmd = 2, cmd =10, cmd =5 !
But what does this command mean ? Can you tell me ?
kind regards
