In the Ve.direct protocol manual is written:
"There are two different implementations of the Text-mode and HEX-mode:
Older implementations • On power up, a VE.Direct interface will always be in Text-mode, ...
Newer implementations • Always have the Text-mode active, regardless of the HEX-messages...
To know more which implementation is applied to your product, please check its specific VE.Direct protocol document."
I cannot find that document for SmartSolar MPPT 100/20. Which implementation is used here?
My main problem is. I only want to read values in text mode, but up and on I receive hex commands that interrupt text protocol and somehow the checksum fails. Although I didn't send any command and didn't actively activate hex mode.
I read it manually with a python script on a raspberry py and original ve.direct USB serial cable.
Best regards,
Michael
