By the way:
I went back to 24.1, and everything works fine, there

[john30]

yes, i meant the csv. and what is the target address? or does the file name carry a target address?

[Kornelius777]

file name is 50.csv

As mentioned above:

fixed a minute ago @Kornelius777.
anyway, the message definition is rather weird.
can you tell me what the parts ErtragTagLow and ErtragTagHigh actually mean? is it valid to combine the two into a single value, e.g. ErtragTag = ErtragTagLow + ErtragTagHigh*256 or similar?
same for the SummeErtrag, but that might be a bit trickier due to 3 bytes, but when the factor is indeed 256, then this could as well be simplified

The problem still exist here too:
Domoticz plugin works fine with any version up to 24.1 but gives the above error with the latest 25.x release.
