Thanks! I got to here…
But I dunno how to configure it… since it’s a pre-built module, all the wires are already connected. According to the Wiki of the original firmware
IR send: IO14 (D5)
IR receive: IO12 (D6)
Wifi LED: IO2 (D2)
IR LED: IO13 (D7)
Button: IO0 (D3)
Here is a photo of the module:
Edit: Found the parameters points and got below messages from remote
00:00:19.620 RSL: RESULT = {"IrReceived":{"Protocol":"UNKNOWN","Bits":254,"Hash":"0xE6DD6E07","Repeat":0}}
00:00:21.518 RSL: RESULT = {"IrReceived":{"Protocol":"UNKNOWN","Bits":128,"Hash":"0x19037C2B","Repeat":0}}

00:00:25.742 RSL: RESULT = {"IrReceived":{"Protocol":"UNKNOWN","Bits":230,"Hash":"0xC242607D","Repeat":0}}
Edit 2: I cannot find the model (RAS-E13CAK/RAC-E13CAK) at IRremoteESP8266/SupportedProtocols.md at master · crankyoldgit/IRremoteESP8266 (github.com), so I guess I need to make the module “learn” the IR codes myself, right?
