I recently put together using a ESP8266 a simple but effective IR remote hub, that I can use to reuse old remotes "manually translating" the hex from one to other and using a IR LED to send back to the devices. I also can send those commands through wifi and build many wifi remotes to my devices. It is amazing! But my LG projector that basically have a kinda TV firmware on it (since it can pickup TV signals) has a "Sleep Timer" function but I'm trying to find this specific command to use on it but i could not yet find... I found it to the other LG tv that i have and it does exactly what i'm lookin for... it toggles sleep timer values when pressed. Since my projector is basically a TV and it share's a relativelly old LG tv firmware, this code exists but i can't find yet... And no.. I have the remote but that button is not present on it, in fact, the command exists but not all LG tv's has that button on their remotes.. what is dissapointing.. Other Panasonic TV models that I also have, in fact have a Sleep Timer dedicated button on it, It is so handy!
If anyone has the same model and know the codes or have any idea to how i can found it please add to this thread!

Here some related images:


My projector have a pretty similar interface to that one



I am looking for a direct access to that menu



This is the exact same one that came with my projector...


So far i found those codes to work with my model (LG PH-550):

PWR = 0x20F0B54A;
VOL_UP = 0x20F040BF;
VOL_DOWN = 0x20F0C03F;
INPUT = 0x20F0F708;
QUICK_MENU = 0x20F0A25D;
MENU1 = 0x20F0C23D;
ENERGY_SAVING = 0x20F0A956;

BACK = 0x20F014EB;
UP = 0x20F002FD;
DOWN = 0x20F0827D;
LEFT = 0x20F0E01F;
RIGHT = 0x20F0609F;
OK = 0x20F022DD;
MUTE = 0x20F0906F;
RED = 0x20F04EB1;
GREEN = 0x20F08E71;
BLUE = 0x20F08679;
YELLOW = 0x20F0C639;

I've also mapped the others my remote have but didn't needed so not added to the ESP's final code;


To my other kinda more recent LG tv.. (42-LF6500 - webos 2.0) have proof working those codes:
