goodwe: Error in reading ECO mode data on GW6000ES20 (ESN version ARM v8)
Thanks for adding the ESN to also include eco mode v2! However it looks like the ESN version has a slightly different data encoding as it reports errors on the inverter_check.py on eco mode settings. I have been reversing the data with Solar Go and Wireshark, results below:

Found some additional register for setting mode:
47605, 47609 and 47612. Now the question is how these registers should be added? ETT only? For all? From a specific arm version?
Goodwe has confirmed that Selfuse and General are the same so clearly my followup question was “why 2 different settings and does both ETU and ETT have 5 Selfuse”
Goodwe also confirmed that new 745 platform is ETT (15K-30K) and ETU (5K-10K) is platform 205.
So we can use serial number to decide platform.
I see now. Ad 1) yes it seems goodwe started to use more values for the on/off, probably because they are re-using the “eco mode” register for more things now. It used to be just 0, -1 now it seems to be this:
I need to adjust the code.
Ad 2) I am not sure, spec say it’s 2 bytes only, but I will look at it, since there is already report of 200% value, so there indeed is something odd there
