Trying to get it to work with Mitsubishi AC

[ferbulous]

Hi, my ac is mitsubishi, before flashing the homekit firmware, I installed tasmota-ir to test sending ir command and it works just fine to control the ac.
I did long press button, led starts blinking, pressed the power button of the ac remote, then led stops blinking.
However it doesn't seem to control my ac just yet.
Here's the log output

LINE 171:  Init  Ac_Protocol: 15
LINE 175: EEPROM Ac_Protocol: 15

Init Ac_Protocol is default protocol pre-built-in, 15 is COOLIX,
EEPROM Ac_Protocol is protocol set by long press button then save to EEPROM,
Why same 15 ?

Check your original ac remote,
Is it mitsubishi like you said?

Then retry.
