    :image: air-conditioner.svg

The ``midea`` component creates a Midea air conditioner climate device.

.. note::

    This protocol also used by some vendors:

        - `Electrolux <https://www.electrolux.ru/>`_
        - `Qlima <https://www.qlima.com/>`_
        - `Artel <https://www.artelgroup.com/>`_
        - `Carrier <https://www.carrier.com/>`_
        - `Comfee <http://www.comfee-russia.ru/>`_
        - `Inventor <https://www.inventorairconditioner.com/>`_
        - `Senville <https://senville.com/>`_
        - and maybe others

    Control is possible with a custom dongle. Example of hardware implementation is `IoT Uni Dongle <https://github.com/dudanov/iot-uni-dongle>`_ or `Midea SLWF-01pro <https://www.ebay.com/itm/164956459539>`_ (`store <https://smartlight.me/smart-home-devices/wifi-devices/wifi-dongle-air-conditioners-midea-idea-electrolux-for-home-assistant>`_, `Tindie <https://www.tindie.com/products/smartlightme/wifi-dongle-for-air-conditioners-midea-electrolux>`_).

Additional control options using IR commands
--------------------------------------------

It is possible to use the FollowMe function and some other features available only through IR commands.
Below is an example of how to send FollowMe commands with the values of your sensor using the :doc:`../remote_transmitter`
component, as well as control the light of the LED display.

.. code-block:: yaml

    # Example configuration entry

    remote_transmitter:
      pin: GPIO13                       # For iot-uni-stick.
      carrier_duty_percent: 100%        # 50% for IR LED, 100% for direct connect to TSOP IR receiver output.

    sensor:
      - platform: homeassistant
        entity_id: sensor.room_sensor   # Sensor from HASS
        internal: true
        filters:
          - throttle: 10s
          - heartbeat: 2min             # Maximum interval between updates.
          - debounce: 1s
        on_value:
          midea_ac.follow_me:
            temperature: !lambda "return x;"
            beeper: false               # Optional. Beep on update.

    # template buttons for sending display control command and swing step actions
    button:
      - platform: template
        name: Display Toggle
        icon: mdi:theme-light-dark
        on_press:
          midea_ac.display_toggle:
      - platform: template
        name: Swing Step
        icon: mdi:tailwind
        on_press:
          midea_ac.swing_step:


Example of Beeper Control Using a Switch
----------------------------------------

.. code-block:: yaml

    switch:
      - platform: template
        name: Beeper
        icon: mdi:volume-source
        optimistic: true
        turn_on_action:
          midea_ac.beeper_on:
        turn_off_action:
          midea_ac.beeper_off:
