I too have an LG. I tried to control it with a Flipper Zero but it didn't respond well. I figure the codes are more of a state machine rather than simply replaying them. I didn't pursue it further though.
Based on the behaviour of the remote and the AC unit, it works just like the Comfee unit where the remote sends the whole state (mode, temperature setpoint, fan speed) to the AC unit. The remote has a display on it showing the mode, fan speed, temperature, etc.
That doesn't tell me anything about how the actual protocol works though. I still need to buy an IR receiver and start decoding the protocol.
