Exception while reading data

First and foremost - this is a great project
After several long days - I have got running for the most part.

My basic setup is:

  • Inverter (192.168.2.249) --> eth1 --> Rasp3bian7 (192.168.2.249) --> eth0 --> router2 (Fritzbox)--> router1 (Hitron-ISP)--> Internet
  • The inverter is an SE4000H.

Trying to get data from the inverter, there is nothing coming up.
After that, I execute test1 and test2.
Test2 gives some info: "Exception while reading data: bytearray index out of range" (look at test2).
Could be this "exception" the reason for nodata ??

Question
If yes how to solve this exception
Is there anybody who give same help ??

Thank you
