Solariot + SMA Inverters xx000TL-20

[Hoerli1337]

Hello!
I'm trying to get the whole thing up and running with two SMA inverters.
Have the STP 9000TL-20 and 8000TL-20 here.
I have built myself a suitable py file - linked below - but this doesn't seem to work that way.
When I run it, I get the following message:

root@ctSolariot:/opt/solariot# ./solariot.py -v
INFO:root:Loaded config sma-inverter-xx000tl-20

Traceback (most recent call last):

  File "/opt/solariot/./solariot.py", line 447, in load_sma_register
    message = BinaryPayloadDecoder.fromRegisters(
TypeError: fromRegisters() got an unexpected keyword argument 'endian'

From python I have unfortunately not yet so much ahnung. :(
