Thank you very much for this file. I tested it on my Sofar 12KTLX-G3 with LSW3_15_270A_1.50 logger. I needed to change some request codes though, otherwise I got various exceptions in the parser. My requests look like this:

requests:
  - start: 0x0400
    end: 0x042E
    mb_functioncode: 0x03
  - start: 0x0480
    end: 0x04AF
    mb_functioncode: 0x03
#  - start: 0x0500
#    end: 0x041F
#    mb_functioncode: 0x03
  - start: 0x0580
    end: 0x0589
    mb_functioncode: 0x03
#  - start: 0x0600
#    end: 0x060A
#    mb_functioncode: 0x03
  - start: 0x0680
    end: 0x069B
    mb_functioncode: 0x03

I needed to change all requests from ending with 4 to ending with 0. Also, the 0x500 start requests looks wrong and was giving me issues. The battery request (0x0600) works fine, but since I don't have a battery I just commented it.

I have HYD 5-20KTL-3PH and Logger is LSW3_15_270A_1.53.

I tested the above config with Sofar HYD 6000-ES and LSW3_15_FFFF_1.0.57

This is the error I get:
