Hi,
I have an acson AC that is controlled by a ir remote. I have GC itach and I used the ilearn software to learn the remote codes.
I am experiencing a very weird behavior. I learn the command and it works fine. But when I test it a second time it does not.
This is the same for all commands.
I am pasting the command for the same function but see how it is different in the end. Now If I use the commands...no guaranty that they will work. I am new to this...what can I do?

The two posted IR signals (written in Pronto Hex notation) are identical.  After the first 4 numbers, the remaining numbers are just pairs of on and off durations expressed in hedadecimal notation (base 16) in units of the modulation period of the IR light.  The IR frequency here is 38KHz, so the endng 303 versus 304 "difference" is really 26 microseconds on a duration of 20072 microseconds.  Completely insignificant.

Air conditioners typically are controlled differently from AV components.  In AV equipment, pressing e.g. Volume Up on the remote will always send the same command to the AV--increment the volume. The AV keeps track of the actual volume level.  In most ACs, the remote remembers e.g. the temperature and pressing Temp Up sends a different signal each time.  That is, it actually sends the requested temperature and not a increment temperature signal.  Your signals have 64 bits of information, and probably the complete state of the AC is being sent on each press of any button.

Check whether this is true by setting the AC to the minimum temperature and record each IR signal as you increase temperature. I like to use the Import function of IR Scope to get a decode of the signal. That's a lot easier to read than the Pronto Hex notation.

If you think you still want to use your GC hardware to control the AC, we'll need to figure out the format of the commands. That can be done by systematically recording the IR signals for each possible state associated with a button, keeping track of which signal corresponds to any state. Then we can parse out which bits control each function.

Hi,
thanks for your reply. Gave up on this and bought this device to do the job. sensibo.com but guess what they have acson ac codes but not for this particular ones. Now either I ship my remote to Israel or send then hex codes.
So back to square one. You are right that the AC send the complete status. So for example if I press power on it will send the command plus whether the AC is on cold or hot and the temperature. So basically what you see on the remote is sent to the AC.
So what can I do to get hex codes for this AC. Any help would be greatly appreciated.
Thanks

I'm not sure what you are asking for.  You can learn all the codes-- one each for all combinations of fan, temperature, timer, sleep, etc-- and send these to sensibo.  Or you can learn a subset of the signals, and we'll try to decode these so that the rest of the signals can be predicted, and then send that derived encoding system to sensibo.

For example, instead of learning all of the temperatures, you could learn the signal from minimum and maximum and 2 or three in the middle of the range.  Then leave the temperature at one fixed value, and learn all the variations of fan speed.  Once you have these learned , post the Pronto Hex here, and we'll try to decode it.
