Installation

1. Using HACS (recommended way)

This integration is a official HACS Integration.

Open HACS then install the "Rewe" integration.

If you use this method, your component will always update to the latest version.

2. Manual

• Download the latest zip release from here
• Extract the zip file
• Copy the folder "rewe" from within custom_components with all of its components to <config>/custom_components/

where <config> is your Home Assistant configuration directory.

NOTE: Do not download the file by using the link above directly, the status in the "master" branch can be in development and therefore is maybe not working.

Configuration

Go to Configuration -> Integrations and click on "add integration". Then search for Rewe.

Getting the rewe market ID

1. Go to the REWE Marktsuche
2. Enter your city or PLZ and choose your desired REWE
3. Select "Marktinfos"
4. Copy the marked id from the URL

Configuration Variables

• market_id: Enter your rewe market id

Lovelace cards

Sample Lovelace card from KrizzeOne

Provided by KrizzeOne:

# **Süßes und Salziges**
|            |        |       |
| :------------: |:------------- | -----:|
 {%- set product_list_loop =  state_attr('sensor.rewe_440421', 'discounts') -%}

{%- for product in product_list_loop -%} {% if 'Süßes & Salziges' in product.category and product.product != '' %}
| <img src="{{product.picture_link[0] }}" width="50" height="50"/> | {{product.product }}
| ![badge](https://badgen.net/badge/{{ product.price | urlencode }}/€)
|  {%- endif -%}
{%- endfor -%}

Downsides / Considerations:

• It takes up to 4sec to load the content if you choose multiple product categories
• Price tags are build via https://badgen.net and most of the time you have to reload your lovelace page to get all badges
• Product images aren't square all the time. Sometimes they look a bit distorted
• By using table layout as I do, Lovelace cards looks different if you have short/long product names. This drives me crazy and I hope I will have a more robust solution in the future.

    {% if 'Spezi' in product.product or 'Käse' in product.product or 'Nutella' in product.product %}

    {{product.price.price }} € - {{product.product }}

    {{ product.picture_link[0] }}
    {%- endif -%}
    {%- endfor -%}
