Midea Air Conditioner
=====================
.. seo::
:description: Instructions for setting up a Midea climate device
: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://smartlight.me/smart-home-devices/wifi-devices/wifi-dongle-air-conditioners-midea-idea-electrolux-for-home-assistant>`_ (`CloudFree <https://cloudfree.shop/product/ductless-hvac-wi-fi-module/>`_, `Tindie <https://www.tindie.com/products/smartlightme/wifi-dongle-for-air-conditioners-midea-electrolux>`_).
The Midea air conditioner requires the UART to be configured with ``baud_rate: 9600``. The hardware requires **5V logic levels** and does not appear to work with 3.3V logic levels. Use a logic level shifter if building your own dongle.

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.
