Control Gree AC using ESPHome and IRremoteESP8266 - EXAMPLE

IR remote - Avatto S06, Geeklink IR Bridge

• Create file "gree_ir.h" in folder "config\esphome\gree", where "config" is HA configuration folder.
• Set remote transmitter pin const uint16_t kIrLed = 14;
• Edit your ".yaml" file like "ir_bedroom.yaml".

UART:

• port 3v3 of the device to the 3v3 of the converter.
• port TXD of the device to the RXD of the converter.
• port RXD of the device to the TXD of the converter.
• port GND of the device to the GND of the converter.
• port IO0 of the device to the GND of the converter.

Flash using ESPHome-Flasher https://github.com/esphome/esphome-flasher/releases. First flash with UART, other flashes on air.

Result:

Current temperature sensor - your current Home Assistant temperature sensor:

sensor:
  - platform: homeassistant
    id: current_temperature
    entity_id: sensor.temperature

Set temperature sensor - call set_temp_sensor method:

climate:
- platform: custom
  lambda: |-
    auto bedroom_ac = new GreeAC();
    bedroom_ac->set_temp_sensor(id(current_temperature)); 
    App.register_component(bedroom_ac);
    return {bedroom_ac};

  climates:
    - name: "Bedroom AC"

Service esphome.ir_bedroom_set_data - set all data to AC with one 'beep':

- service: esphome.ir_bedroom_set_data
  data:
    hvac: 'cool'
    temp: 22
    fan: 'auto'
    swing: 'off'
    light: True

Switch switch.bedroom_ac_light - current AC light switch.

Remember and sync states after node restart

Add to HA configuration an input_number to store the target temperature:

input_number:
  status_climate_bedroom_temp:
    min: 0
    max: 50

Add to HA configuration a few input_text to store operation mode, fan mode, swing mode:

input_text:
  status_climate_bedroom_hvac:
  status_climate_bedroom_fan:
  status_climate_bedroom_swing:

Use automations to sync climate states with the statuses:

automation:
- id: sync_climate_bedroom_hvac
  alias: Sync Climate Bedroom HVAC mode
  initial_state: 'on'
  trigger:
    - platform: state
      entity_id: climate.bedroom_ac

    - service: input_text.set_value
      target:
        entity_id: input_text.status_climate_bedroom_hvac

        value: "{{ states('climate.bedroom_ac') }}"
