 | Current temperature | The unit's room sensor, converted to the unit's temperature scale. Replaced by the **External Temperature Sensor** when one is set. That changes only what Home Assistant shows; the unit keeps regulating on its own sensor. |

 | Fan mode | Auto, Low, Medium-Low, Medium, Medium-High, High, plus Turbo and Quiet when the unit has them. See below. |

 Extra attribute: `current_outside_temperature`, the outdoor sensor value in the unit's temperature scale, when the unit has an outdoor sensor. Read it with `{{ state_attr('climate.your_ac', 'current_outside_temperature') }}`.
