You can use esphome (or Home Assistant) sensors to report the current temperature and humidity to the Home Assistant climate component

sensor:
  - platform: homeassistant # https://esphome.io/components/sensor/homeassistant.html
    id: indoor_unit_1_sensor_temperature # ESPHome sensor name used below
    entity_id: sensor.room_1_sensor_temperature # Home Assistant entity_id
    filters: # Sensor value must be °C, convert from °F if reading from fahrenheit sensor
      - lambda: return fahrenheit_to_celsius(x);

  - platform: homeassistant
    id: indoor_unit_1_sensor_humidity
    entity_id: sensor.room_1_sensor_humidity

climate:
  - id: !extend indoor_unit_1
    sensor: indoor_unit_1_sensor_temperature
    humidity_sensor: indoor_unit_1_sensor_humidity

Place component in read only mode to capture OEM controller data.
