Error in IRHVAC COOLIX protocol? Fan only mode sends dry mode command instead

[mdk2412]

I use a wemos D1 mini with tasmota-ir to control my AC using the coolix protocol. Everything works beautifully, with one exception: trying to set fan only mode. To diagnose this issue I used another tasmota-ir device to record what actually was sent. This is what I found:

transmitter: IRHVAC {"Vendor":"COOLIX","Mode":"Fan","Power":"On","FanSpeed":"Auto"}

results in

receiver: {"IrReceived":{"Protocol":"COOLIX","Bits":24,"Data":"0xB21FC4","DataLSB":"0x4DF823","Repeat":0,"IRHVAC":{"Vendor":"COOLIX","Model":-1,"Command":"Control","Mode":"Dry","Power":"On","Celsius":"On","Temp":25,"FanSpeed":"Auto","SwingV":"Off","SwingH":"Off","Quiet":"Off","Turbo":"Off","Econo":"Off","Light":"Off","Filter":"Off","Clean":"Off","Beep":"Off","Sleep":-1,"iFeel":"Off","SensorTemp":null}}}

transmitter: irsend {"Protocol":"COOLIX","Bits":24,"Data":"0xB2BFE4","DataLSB":"0x4DFD27","Repeat":0}

results in

receiver: {"IrReceived":{"Protocol":"COOLIX","Bits":24,"Data":"0xB2BFE4","DataLSB":"0x4DFD27","Repeat":0,"IRHVAC":{"Vendor":"COOLIX","Model":-1,"Command":"Control","Mode":"Fan","Power":"On","Celsius":"On","Temp":30,"FanSpeed":"Auto","SwingV":"Off","SwingH":"Off","Quiet":"Off","Turbo":"Off","Econo":"Off","Light":"Off","Filter":"Off","Clean":"Off","Beep":"Off","Sleep":-1,"iFeel":"Off","SensorTemp":null}}}

transmitter: IRHVAC {"Vendor":"COOLIX","Mode":"Dry","Power":"On","FanSpeed":"Auto"}

results in

receiver: {"IrReceived":{"Protocol":"COOLIX","Bits":24,"Data":"0xB21FC4","DataLSB":"0x4DF823","Repeat":0,"IRHVAC":{"Vendor":"COOLIX","Model":-1,"Command":"Control","Mode":"Dry","Power":"On","Celsius":"On","Temp":25,"FanSpeed":"Auto","SwingV":"Off","SwingH":"Off","Quiet":"Off","Turbo":"Off","Econo":"Off","Light":"Off","Filter":"Off","Clean":"Off","Beep":"Off","Sleep":-1,"iFeel":"Off","SensorTemp":null}}}

That is, IRHVAC command with "Mode":"Fan" gives the wrong result identical to "Mode:Dry". So I suspect that there is an error in the translation from IRHVAC to actual irsend command somewhere. But where do I look for it?

Has been solved: crankyoldgit/IRremoteESP8266@c2b5235

Thanks. We will wait for a new release of IRRemoteESP8266

[mdk2412]

I can confirm that with a self-compiled version of tasmota 14.1.0 including this patch the correct command is sent using IRHVAC.

Since there has been no new release of IRRemoteESP8266 for so long, could this patch (crankyoldgit/IRremoteESP8266@9785cb9) be included in Tasmota without waiting for the new release?
