So I did play with my LG ThermaV 2011 R410A - seems to behave the same as R32. I have found some UNK bytes from your README.

Bytes 6 and 7 are timer related. Looks like a timer for AC units in (JanM321 github).
Byte 6 is timer type:
SIMPLE = 28 hex
SLEEP = 18 hex
Byte 7 is time in minutes ex. 3C = 60 min ; 78 = 120min - I'm sure for time > 255 min it will work the same way as on JanM321 repo.

Will post my finding if I'll find more
