Midea Air Conditioner¶
The midea
component creates a Midea air conditioner climate device.
Note
This protocol also used by some vendors:
Control is possible with a custom dongle. Example of hardware implementation is IoT Uni Dongle or Midea SLWF-01pro (CloudFree, Tindie).
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.

Automations¶
midea_ac.power_on
Action¶
This action turn on power. The mode and preset will be restored to the last state before turned off.
on_...:
then:
- midea_ac.power_on:
midea_ac.power_off
Action¶
This action turn off power.
on_...:
then:
- midea_ac.power_off:
midea_ac.power_toggle
Action¶
This action toggle the power state. Identical to pressing the power button on the remote control.
on_...:
then:
- midea_ac.power_toggle:
midea_ac.follow_me
Action¶
This action transmit IR FollowMe command telling the air conditioner a more accurate room temperature value to be used instead of the internal indoor unit sensor.
on_...:
then:
- midea_ac.follow_me:
temperature: !lambda "return x;"
beeper: false
Configuration variables:
temperature (Required, float, templatable): Set the value of a internal temperature sensor.
beeper (Optional, boolean, templatable): set beep on update. Defaults to
False
midea_ac.display_toggle
Action¶
This action toggle ac screen. Works via UART if supported or Remote Transmitter.
on_...:
then:
- midea_ac.display_toggle:
midea_ac.swing_step
Action¶
This action adjust the louver by one step. Remote Transmitter required.
on_...:
then:
- midea_ac.swing_step:
midea_ac.beeper_on
Action¶
This action turn on beeper feedback.
on_...:
then:
- midea_ac.beeper_on:
midea_ac.beeper_off
Action¶
This action turn off beeper feedback.
on_...:
then:
- midea_ac.beeper_off:
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 Remote Transmitter component, as well as control the light of the LED display.
# 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:
