01 04 messages have different format

[Jeltel]

As already discovered by yourself the 01 04 data messages are different and cannot be processed by your script. They are processed on the Growatt Servers, so the data connection is still there.

Hopefully we can fix this.

below is the message we need to decode:

As you can see a lot of Growatt. Were earlier there were a lot of empty values (dots). Maybe we need another decode key?
