Unit IR Home Assistant Integration

This section describes the configuration methods and practical steps for integrating the Unit IR infrared transmitter/receiver unit into Home Assistant.

1. Preparation

Environment Setup

1. Install Home Assistant by following the official Home Assistant documentation.
2. Install the ESPHome Device Builder add-on by following the official ESPHome documentation.
3. Refer to the official ESPHome IR documentation:

• Remote Transmitter
• Remote Receiver
• Setting up RMT Devices

4. Confirm the GPIO pin definitions of the controller device (pins vary by controller).

Hardware Products

• Unit IR
• A compatible controller (such as an Atom, Stamp, Stick, Core, or Basic series device)

2. Modify Configuration

Configure IR Transmitter/Receiver

1. Basic configuration example:

remote_receiver:
  pin: GPIOXX
  dump: all

remote_transmitter:
  pin: GPIOXX
  carrier_duty_percent: 50%

The GPIO pins will vary depending on the controller used. For example, using the AtomS3 series as a controller:

# GPIO1 input
remote_receiver:
  pin: GPIO1
  dump: all

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

2. Once the IR configuration is complete, you can add devices like IR Climate. Taking 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

3. After saving, compile and upload the firmware. Add the device to Home Assistant to see the IR entity:
