Unit IR Home Assistant Integration

Unit IR is a short-distance optoelectronic module with integrated infrared transmission and reception capabilities. It features a 940nm infrared LED transmitter and a 38kHz hardware demodulation receiver, supporting modulation transmission and automatic demodulation reception of standard infrared protocols such as NEC

Configuring IR Transmitter/Receiver

remote_receiver:
  pin: GPIOXX
  dump: all

remote_transmitter:
  pin: GPIOXX
  carrier_duty_percent: 50%

The GPIO pins here will vary depending on the master device used. For example, using AtomS3 series as the master:

# GPIO1 input
remote_receiver:
  pin: GPIO1
  dump: all

# GPIO2 output
remote_transmitter:
  pin: GPIO2
  carrier_duty_percent: 50%

After completing the IR configuration, you can add IR Climate and other devices. Using a Midea air conditioner as an example:

climate:
  - platform: coolix  # or media_ir
    name: "Media AC"
    visual:
      min_temperature: 18
      max_temperature: 30
      temperature_step: 1

After saving, compile and upload the firmware, then add the device to Home Assistant, and you will be able to see the IR entities:
