How can I get this working in EspHome/Homeassistant?

bektorkhan commented

You can't, not without incorporating TFTeSPI in ESPHome. T-HMI uses 8-bit data to ST7789V and some strange pin assignments . I have like you been struggling, but I'll look into using TFTeSPI arduino lib with ESPHome.

I got it to work with help of this: https://github.com/landonr/lilygo-tdisplays3-esphome/tree/main
You need to run ESPHome by commandline, Warning: Bat_ADC is used as Reset and GPIO43 as RD did not work otherwise. Both Reset and RD are strapped high in Hardware. And I thought this could be a hardware mod.. but it worked without mod of the board. Modifying this file:
.esphome\external_components\6d17677d\components\tdisplays3\display.py :
CONFIG_SCHEMA: This should be set in display def in ESPHome but...
CONF_HEIGHT, default=320
CONF_WIDTH, default=240
Changing the buildflags:
cg.add_build_flag("-DTFT_INVERSION_OFF")
cg.add_build_flag("-DTFT_RD=43")
cg.add_build_flag("-DTFT_D0=48")
cg.add_build_flag("-DTFT_D1=47")
cg.add_build_flag("-DTFT_D2=39")
cg.add_build_flag("-DTFT_D3=40")
cg.add_build_flag("-DTFT_D4=41")
cg.add_build_flag("-DTFT_D5=42")
cg.add_build_flag("-DTFT_D6=45")
cg.add_build_flag("-DTFT_D7=46")

ESP32-S3 not supported in IRRemote library? https://github.com/Arduino-IRremote/Arduino-IRremote
in search:- the ESP32-S3 appears to have Remote Control Transceiver (RMT) -ESP documentation that perhaps the ESP32-S3 natively has support for receiving IR signals. is it ? or any suggest any other library
