Keeping RF/IR devices in sync when users still use original remotes

Daikin? I am pretty sure I have seen someone did the module here.
OK this is my 5 second search:
Need Daikin Wifi? Use the Open-Source Faikin ESP32 Hardware instead of the official wifi Modules - Third party integrations - Home Assistant Community

And if you google search you probably can see a lot more. Tip: use image for search results.
