I have captured all buttons on the remote with oarusb04g with extender.
I have uploaded rmir file with learned signals to the file section.

I am not very familiar with how a a/c remote works. Like does it send only one signal mode when I press mode, or does it send the temp set, fan speed, timer status, etc to the a/c. Also, does pressing temp+ temp- only send two signals? or does pressing temp+ at 16, 17, 18 , 19 etc all different.

I haven't take a look at the pattern of the signals. If they are simple enough, I maybe able to create a new protocol name FF FF and run it from there.

The ideal will be for someone to give it a protocol, maybe. But it is out of my scope.

So, due to my lack of understanding of how a remote for a/c works and my lack of capability to create a new protocol. I will wait for forum experts to come in and help.

Thanks. Let me know if you need more reads of the buttons on my remote.

The signal is very similar to the NEC signal but it's longer. Normally, A/C signals are, as you suspect, really a combination of all the settings, so TEMP+ isn't really the code that gets sent, it's really the code for the next temp. The only way to truly capture an A/C signal is to set everything to a known state, preferably the lowest state for each setting, then capture the signal every time you raise one of the settings, like FAN (low), FAN (medium), FAN (high), TEMP+ (66*), TEMP+ (67*), etc.

And then once we have all of that data, the real question is, would a protocol that re-creates it be useful to you? Because, we won't be able to re-create a TEMP+ button, instead we will create discrete codes for each setting, so a single button would set the FAN to high, the TEMP to 68*, etc etc.

Here's what I got from your captures...

Thanks for ypur explanation. It helps me understand the basics of how an a/c remote works. However, after second thought, I find programming all the a/c remote signals to a one for all remote to have little use for me. For example, setting one button to set temp to 27, a second button to 28, and one more to fan low, etc. It is not easy to memorize these buttons at all.

Maybe it is easier to buy a generic remote for gree for a spare.
But thanks for your help and explanation again.

Do your learned signals work, and if so, do they do what you expected, or do they set everything to a specific level?

Just push the button you learned.

Thanks for the reply. I assume that the learned signals take precedence over the programmed device signals. So I tried a few of the buttons I learned, but it did nothing to my a/c. This includes power on, fan auto, mode auto, mode cool.

You can find the rmir with more signals learned here

If you would like to deal with ict files, I have include it here
