Automating Daikin AC/Heating units (UK) (alien.top)

Hi, I've been quoted on installing Daikin FTXA-AW units for heat/cooling in my home (UK), the installer says these can be integrated with, but can't really offer me any specifics. They come with a standard IR remote, and I know I could probably rig up an IR blaster, but would rather do something more integral.

Does anybody have any experience with integrating with these?

It looks like from the data sheets that it supports a bunch of accessories for integration with things like Modbus or KNX, none of which I have any experience with.

I use OpenHAB for automation, so fairly free with what I plug into. Ideally I'd like to connect these units up with Ethernet and control them over IP, but I would have no idea where to start with that. I guess I'd want to be able to read current state, tell it to heat or cool at various levels of aggressiveness. Has anybody got any experience with this sort of thing?

There is an app that works with these, but this relies on an external Internet connection. I need a solution that doesn't require my internal network to have to talk out to the Internet to control something internal.

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
