I use this link to send and control gree A/C https://github.com/ToniA/arduino-heatpumpir
and change

#define GREE_AIRCON1_MSG_SPACE  19000

to

Code: Select all

 #define GREE_AIRCON1_MSG_SPACE  20000

and use this link to decode IR https://github.com/ToniA/Raw-IR-decoder-for-Arduino

for mode: heat temp:25 swing:off sleep:off

remote Gree control decode and NEC is:

and IR sender is:

ONE SPACE:    1609 

Decoded NEC: 30900A00 (32 bits)

they NEC are different and Gree A/C doesn't work with IR sender ,what's the problem? how should I change the time constants in this https://github.com/ToniA/arduino-heatpu ... atpumpIR.h ??

Hi Isan

Unfortunately, I am not familiar with that library you are using, so it may be better to post a new issue on their Github page.

One thing to bear in mind is that the name of the AC is often a clue to the protocol used.....but NOT ALWAYS, as some manufacturers will re-badge units from other OEMs. So you can get a mix of IR protocols being used by the same manufacturer.

Without a set of captured signals for your device, I cannot offer any advice.

how should I captured signal for my device ?
with this https://www.analysir.com/blog/2014/03/1 ... s-arduino/?

Posted: **Wed Dec 27, 2017 1:48 pm**

Yes...you got it.

If you post the output, I will look at the signal.

I have cleaned it up in AnalysIR, exported it and posted below:

As you can see it comes up as an Electrolux signal (67 bits), with a Hex value of 0x1D7003052E004000F.
Don't be too concerned about the naming, as they can be often found under different 'reseller brand names'

Posted: **Sat Dec 30, 2017 10:07 am**

you are say true but I don't know where is the problem because my hex value from remote in heat mode and temperature 25 is : 3090060A (32 bits)
and IR sender hex value is: 30900000 (32 bits)
problem in checksum or timing or else?

Posted: **Sat Dec 30, 2017 11:59 am**

You are probably seeing 32 bits, if using something like IRremote...which does not generally support more than 32 bits (and is likely confusedby the additional bits).

Also, beware that some systems will report HEX values based on different bit orders, depending on how they are implemented.

My previous post with 67 bits is correct.

Posted: **Sun Dec 31, 2017 5:48 am**

32 or 67

,they have different in last bits that is my mean ,and I ask for this reason

Posted: **Sun Dec 31, 2017 3:38 pm**

Sorry...I dont really understand the point you are trying to make.
