Homebridge Smart Thinq LG Airco

This Homebridge plugin allows control over a Smart Thinq enabled LG Airco unit.

To install this plugin simple type sudo npm install homebridge-lg-airco -g --unsafe-perm=true. Next open the config.json that contains your Homebridge configuration and add a block like the following one to the accessories array:

{
    "accessory": "LgAirCooler",
    "name": "LG Airco",
    "deviceId": "OPTIONAL_DEVICE_ID",
    "model": "AC RAC_056905_WW",
    "country": "BE",
    "language": "en-UK",
    "maxCoolingTemp": 26,
    "minCoolingTemp": 18,
    "maxHeatingTemp": 30,
    "minHeatingTemp": 5,
    "updateInterval": 60000,
    "debug": false,
    "dummy": false
}

The accessory name has to be LgAirCooler to link to the plugin. The name field is for the display name in the HomeKit app. The deviceId field is the device id for you cooler, optional, only provide this if you have more than one AC unit! instructions below how to obtain it! The country field is the 2 letter country code (XX) of the chosen country of your LG SmartThinq account. The language field is the 4 letter language code (xx-XX) of the chosen language of your LG SmartThinq account. The model field is the model of the AC unit being used. This value is used to show in the information section. The maxCoolingTemp field is the maximum settable temperature when in COOLING mode. The minCoolingTemp field is the minimum settable temperature when in COOLING mode. The maxHeatingTemp field is the maximum settable temperature when in HEATING mode. The minHeatingTemp field is the minimum settable temperature when in HEATING mode. The updateInterval field is the interval that is used to fetch new state data from the AC unit. In milliseconds! The debug field is the boolean that enables or disables debug logging, set this to false unless collecting logs. The dummy field is the boolean that enables mocking out the LG API and will instead use a dummy AC unit with no network calls, only for development & testing!

The initial state will be fetched shortly after booting your Homebridge instance. After that an update of the state is performed every minute.

Requirements

• A SmartThinq compatible LG airco unit (Tested with an PC12SQ NSJ)
• Registered through the V1 LG API!!! V2 API is NOT YET supported!!!

Setup guide

• Open a terminal on the device where you installed this plugin and type: cd "$(npm root -g)" && cd homebridge-lg-airco/resources/wideq
• Your terminal should navigate to the folder, if any error comes up the plugin was not installed correctly!
• Execute the command python3 example.py -c country-code -l language-code -p path-to-wideq-file-in-homebridge-folder where you should replace country-code, language-code and path-to-homebridge-folder with the respective values. For example: python3 example.py -c BE -l en-UK -p /home/pi/.homebridge/wideq_state.json
• Make sure the wideq_state.json does not exist yet! If the file is corrupted, delete it before executing the command again!
• Follow the instructions on the screen, and paste the resulting URL back into the terminal. The command will now print out a list of all known devices for your account. If wanted select the one you want and paste the value in the config.json file at the deviceId field of the corresponding accessory definition. It will also generate a file in which the session is stored in the Homebridge folder.
• The plugin is now fully ready to be used in Homebridge!

This code makes use of the WideQ library, more information here. Some changes have been made to the included version of the WideQ library.
