Big shout out to @revk and their https://github.com/revk/ESP32-Faikin project that reverse engineers remote control protocol of Daikin AC units and removes dependency on semi-working IR blaster controllers or official Daikin cloud back-and-forth and proprietary phone app remote. I live in Japan - home of Daikin and had zero issues installing and making Faikins work in all my domestic units. They did not have S21 port so I also had to add official interface boards. #homeassistant #faikin
