Control Samsung The Frame Art Mode using ESPHome to talk to the One Connect box with RS232/Ex-link. You need ESP8266 or ESP32 and a UART/TTL to RS232 converter, like something using MAX2323 chip.
No custom uart component, reading the status is done using esphome uart bus debugging, with additional code parsing the received bytes after 100ms of silence.
esphome compile samsung.yaml
esphome upload samsung.yaml --device 192.168.42.48
