gree "YAL" #133

Closed ikilledmypc closed 2 years ago

ikilledmypc commented 2 years ago

I have an electrolux heatpump that seems to work with the gree protocol. Using the Raw IR decode tool linked in the readme I found that the remote that is labeled as YAL1F works exactly as a gree YAC except for a missing "eco" feature. The only difference seems to be the pulsecount being 213. By changing the if statment to if ( pulseCount == 142 || pulseCount == 161 || pulseCount == 213) { to include the pulse count 213 all decoding seems to work. The only difference is the fan speed from what I can tell. instead of byte 14 it is on byte 22 but the decoding works by changing 14 to 22. I would love to include this into this library but this is where I get stuck. If I set the protocol to greeac I am no longer able to sent commands to the unit ( greeyaa works if that helps). If someone can help me on what to do next I'm happy to do the changes myself.

This is apparently a working implementation: https://github.com/crankyoldgit/IRremoteESP8266/blob/master/src/ir_Kelvinator.h
