Instruccions for flashing and mantaining using the ESPHOME addon in HA

[mshrem]

Hello its been a while since i was able to flash my units but i found a way to use the ESPHOME addon to flash the device on HA directly. You can also check the logs wiresly on the addon or upload any firmware changes and updates.

1 You will need a couple of addons the ESPHome addon , and another addon to put some files inside the Esphome folder in HA (File editor or Samba addon works in here)

2 Copy the contents of esphome/components/ from this repository to the /homeassistant/esphome/components

3 Go to the Esphome tab in HA and add a new device.

• Name your device
• Press skip this step
• Select ESP32 and use recommended settings
• You should get a Congratulations created! message
• Skip again

4 Go to the edit button so you can edit your newly created.yaml file

5 Add the following before the first line and edit to your liking.

substitutions:
  # Unique device ID in HA
  deviceid: "lglivingroom" # XXX
  # Unique device name in HA (sensor names will be prefixed by this name)
  devicename: "LG Living Room" # XXX
  # The input temperature sensor in HA.
  temperature_sensor_entity_id: sensor.my_sensor # XXX
  # Set to "true" if the temperature sensor and Home Assistant use Fahrenheit instead of Celsius.
  fahrenheit: "false" # XXX
  # If multiple controllers are connected to a single indoor unit, only one of them should be
  # configured as "master controller". Slave mode is a new and experimental feature for this
  # ESPHome controller and might not work well.
  # If you're connecting a single controller, this should be set to "false".
  is_slave_controller: "false"

6 Add the following at the end of the file

uart:
  - id: ac_serial
    tx_pin: GPIO25
    rx_pin: GPIO26 # Keep in sync with RxPin in lg-controller.h
    baud_rate: 104

7 Save your changes.

8 3 dots and click install

9 Select plug into this computer

10 Connect your ESP board with a USB cable and select it

11 Wait for the flash to finish

12 Profit you should be able to read it with the ESPHOME addon

I am using latest HA ( core ver. 2024.5.5 ) and latest ESPHOME Addon ( ver. 2024.5.4 ) . During compilation I got few errors like :

• error: 'isnan' was not declared in this scope
• error: 'ESP' was not declared in this scope
• error: 'digitalRead' was not declared in this scope
• error: 'LOW' was not declared in this scope
  Fix which worked for me, I have to add to lg-controller.h two following lines at beginning
  #include "math.h"
  #include "Arduino.h"
  After that , no errors , and My ESP32 works quite well

Update:

Second part to paste under the original ESPHOME YAML

uart:

• id: ac_serial
  tx_pin: GPIO25
  #rx_pin: GPIO26 # Keep in sync with RxPin in lg-controller.h mentioned twice, so comment this one out
  baud_rate: 104

sensor:

• id: temp_sensor
  platform: homeassistant
  internal: true
  entity_id: ${temperature_sensor_entity_id}
• platform: uptime
  name: Uptime

Make shure to copy the "lg_controller folder in your local files see path used

external_components:

• source: /config/esphome/custom_components #this path
  components:
  • lg_controller

climate:

You can also skip copying the files. Just use this for external_components
And if you are afraid this might go away some day, fork it and point to your fork.

external_components:
  - source: github://JanM321/esphome-lg-controller
    components: ["lg_controller"]
