Home Assistant: LG SmartThinQ Component

A Home Assistant component for controlling/monitoring LG devices (currently HVAC & Dishwasher) via their SmartThinQ platform, based on WideQ. The current version of the component requires Home Assistant 0.96 or later.

Here's how to use this:

1. Clone this repository into your ~/.homeassistant directory under custom_components and name it smartthinq. For example, you might do something like this:

   $ cd ~/.homeassistant
   $ mkdir custom_components
   $ cd custom_components
   $ git clone https://github.com/sampsyo/hass-smartthinq.git smartthinq
   

2. Navigate to the WideQ directory. You can either use the copy installed by Home Assistant, or clone it separately by typing something like:

   $ git clone https://github.com/WonchulKang/wideq.git
   $ cd wideq
   

   Authenticate with the SmartThinQ service to get a refresh token by running the WideQ example script. (Eventually, I would like to add a feature to the Home Assistant component that can let you log in through a UI, but I haven't gotten there yet.) Run this in the wideq directory:

   $ python3 example.py -c US -l en-US
   

   For the -c and -l parameters, use your country and language code: SmartThinQ accounts are associated with a specific locale, so be sure to use the country you originally created your account with. The script will ask you to open a browser, log in, and then paste the URL you're redirected to. It will then write a JSON file called wideq_state.json.

   Look inside this file for a key called "refresh_token" and copy the value.

3. Add a stanza to your Home Assistant configuration.yaml like this:

   smartthinq:
       token: [YOUR_TOKEN_HERE]
       region: US
       language: en-US
   

   Use your refresh token and country & language codes. If region and language are not provided, then 'US' and 'en-US' are default. Start up Home Assistant and hope for the best.

Dishwasher Visualization Example

Dishwashers will be automatically added as a new sensor.lg_dishwasher.[ID] entity with various useful attributes. See the below example for how this can be used in the Lovelace UI, which uses the built-in picture-elements card, the circle custom card, the entity attributes card and card mod.

Lovelace configuration is below. Replace [ID] with the entity ID from your dishwasher. Place the dishwasher background image in your Home Assistant local directory.

  - attribute: remaining_time_in_minutes
    attribute_max: initial_time_in_minutes
