I figured this out a few days ago actually. There is a project called ESP32-Faikin you can find it on google pretty easy use that it requires the unit either have a S21 port or X50A port but if your unit has a S403 port then you can use that as well the pinout for the S403 is at https://community.openenergymonitor.org/t/hack-my-heat-pump-and-publish-data-onto-emoncms/2551/117?page=2 just wire it appropriately to the faikin board and you are good to go

Thanks these seem great ordered them on a discount too. Do you know if their own zigbee controllers are any good? They are not that expensive and idk they are from the same brand so maybe its atleast tested for proper color reproduction
