SAC9010QC/SAC12010QC: reconstructing an air-conditioner IR protocol

SAC9010QC/SAC12010QC reconstructs the IR control format of a HomeFit Living or Alaska air-conditioner remote from captured signals. A protocol reference maps its 36-bit command fields, while an ESP8266 or ESP32 web server sends AC settings through a REST endpoint.
