I am trying to add support for my Hitachi RAS-70YHA3 heatpump with remote RAR-3U3. I forked your repo and started an attempt (you'll have to forgive me, I'm not a c++ developer) a few months back, but I struggled a bit. I called it HITACHI_AC296.
My attempt is based on someone else's research on the same protocol. Using what I learnt there I was able to send working signals, I just wasn't able to get it into IRremoteESP8266 properly.
At the time I did not know about auto_analyse_raw_data.py, so I will give that a shot. I just wanted to open this ticket to track progress and have a place for guidance 🙏.
Raw output from IRrecvDumpV2 (I am using a VS1838b, but I don't seem to have had too many issues with it, I don't think):
