Unofficial Bring! plugin for TRMNL

![Plugin view](views/sample.png)

## How to use

### 1. Create a private plugin on TRMNL dashboard

First, create a [private plugin](https://help.usetrmnl.com/en/articles/9510536-private-plugins) with webhook strategy.

You then need to create the view templates for your plugin. Go to the Edit Markup page:

1. paste the contents of [full-height.liquid](views/full-height.liquid) into the Full and and Half Vertical tabs.

1. paste the contents of [half-height.liquid](views/half-height.liquid) into the Half Horizontal and and Quadrant tabs.

### 2. Run the backend service

The backend service runs indefinitely, queries Bring! every 15 minutes to grab the list of items in your shopping list and sends the list to TRMNL if the shopping list changed since the last query.

Have these handy:

1. Bring! account email
1. Bring! account password
1. TRMNL plugin webhook URL. You can find this at the bottom of your private plugin page.

*Note:* If you signed up to Bring! using Apple ID or Google Sign-in or other SSOs you need to create password first. More [here](https://www.home-assistant.io/integrations/bring/#prerequisites).

You can either run the backend service through docker or run the script directly.

#### Docker

Pull the docker image and pass the email, password and webhook url as env variables.<br/>
You can also provide an optional list UUID (see 3. below).

```bash
docker pull ghcr.io/yshrdbrn/trmnl-bring-plugin:main

docker run
    -d
    --name='BringTRMNLPlugin'
    -e 'EMAIL'='<email>'
    -e 'PASSWORD'='<password>'
    -e 'WEBHOOK_URL'='<url>'
    -e 'LIST_UUID'='<list UUID>' # optional
    'ghcr.io/yshrdbrn/trmnl-bring-plugin:main'
```

#### Run the script directly

Clone the repo and rename `.env.example` to `.env` and put in your email, password, webhook url, and optionally list UUID there. Then run the script:

```bash
python3 -m venv venv
pip install -r requirements.txt
python ./main.py
```

### 3. Optional: Determine your list UUID and provide it to the plugin

You can manage several shopping lists on Bring with the same account.<br/>
If you want to choose a specific list, you need to determine its UUID. Otherwise the plugin just uses the first list it encounters (which might not be the first list you see in the app or web page).

```bash
docker run
    -e 'EMAIL'='<email>'
    -e 'PASSWORD'='<password>'
    'ghcr.io/yshrdbrn/trmnl-bring-plugin:main'
    python -u ./fetch_lists.py
```

Or run it without docker (EMAIL and PASSWORD must be set in .env and dependencies installed as in 2. above):

```bash
python ./fetch_lists.py
```

You should get a list of lists like this:

| **Name**  | **UUID**                        |
| --------- | ------------------------------- |
| Groceries | 12345678-90ab-cdef-0123456789ab |
| Stuff     | abcdef01-2345-6789-0123456789ab |

Copy the UUID of the list you would like to display, and set it as `LIST_UUID` either via `-e` in docker or in the `.env` file. Restart your plugin service to apply the change.
