Daikin FTW-CA - control

Hi everyone,
I have a Daikin internal unit model FWT04CATNMV1 which does not have the possibility of inserting original cards or extensions for wi-fi remote controls or home assistants. I read that there are projects with ESP32 but my model does not fall within the scope of compatibility.
Does anyone have experience or recommendations for this type of unit?
thank you in advance.

If your unit does not have an S21 or S403 connector for a wifi controller you could try implementing an infra red remote control: IR Remote Climate — ESPHome

i don’t have a wiring diagram…
i have 2 connector


one is for modbus but i don’t have a idea!

Hi. do you have finded a solution?
Gateway modbus is R04084153577 , but no support for esphome .
i think that the only solution is the IR , but not finded online a working preset for ir remote.

Where are you from? I’m italy, padova.
Bye :slight_smile:
