Gree HVAC

#1 Post by enesbcs » 25 May 2018, 20:33

I've been struggling with a Gree HVAC that i wanted to control by IR for a few days until now.
I think the currently used IRremoteESP8266 library is inadequate for this type of device, because it is using 64 bit long remote codes... i tried arduino-heatpumpir plugin with no success.
finally i've found the above fork that supports Gree:
https://github.com/markszabo/IRremoteESP8266

But sadly it's not a drop-in replacement of the original so i have to modify _P016_IR.ino and _P035_IRTX.ino to compile it. Moreover i converted the IRRecvDump from the above package to learn the control codes from the original remote.
Now i can switch on cooling with 24C with:
IRSEND,GREE,09082050002000D0,64

and switch off with:
IRSEND,GREE,0108205000200050,64

In case of anybody needed, modified source code is attached.

Hi, it seems that Gree libraries has been included in the latest release, but there is no hint how to parameter the commands.

Last year I compiled a custom image with tadiran libraries for Gree AC, but there are so many changes in the latest releases that i cannot include it anymore.

Do you have any experience with the latest IRTX plugin?
