4 months ago The error comes from the umodbus module and more exactly with the call to parse_response_adu here
The response is longer than expected. From a random Sent/Received pair where the error occurs we have the following:

Data 01030a32313036323334323538306e0000where we can see that the response is -> 17 (bytes in total) - 4 (slave address + function code + modbus CRC) = 13 bytes which does not match to the request. Read holding registers with quantity 5 should contain only 10 bytes. The V5 sequence numbers match which lead me to believe that this is something specific to the inverter model / requested register.
As for the ethernet loggers #5 might be helpful.

Hi @jmccrohan and @githubDante!
I have this two issues on my repo: Deye Inverter with LSW3_15_FFFF_1.0.9E Support for Ethernet Logger LSE-3
Both are somehow pointing at first to a little bit older version of Stephans integration to before he was using your lib guys. While the other one requires some additional adjustments the first kinda don't makes sense to me.
I'm now inclined to maybe add some type of a legacy support to my integration to get both flies with one hit. But shouldn't at least the first case be handled by pysolarmanv5?
Thanks, cheers!
