[Feature Request]: Some example lovelace cards

[seb5594]

The request

Nice HA integration here! Could you give out more examples like a markdown card where all "Knaller" sales will be listed or something similar? Would be a good addition

Is your feature request related to a problem?

Thanks for your feature request and your interest in the integration. I will have a look into it.

I would second his request. If there is a way to create a lovelace template, so we don't have to do it on our own every single time, that would be great!

This is how my markdown card looks like:

# **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.price }}€/{{ product.price.regularPrice }}/red)  
|  {%- endif -%} 
{%- endfor -%}

Downside:

• 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.

Hi there, since my market has 389 offers, I had to reduce that number to something I could handle. Therefore, I came up with this mushroom template card. Since it's text-only, it loads pretty fast. Hope it helps:

type: custom:mushroom-template-card
primary: Aktuelle Angebote im Rewe Prospekt
icon: ''
multiline_secondary: true
secondary: |+
  {# This selects the sensor containing the Rewe market ID. 
     Note: Check the very last line of this card configuration. 
           The link shown there should refer to your respective market in order to make sense. 
           In case you're wondering: on double tap because it's more user-friendly.  #}
  {%- set product_list_loop = state_attr('sensor.rewe_4040274', 'discounts') -%}

  {# This defines a list of things we don't want to see in our result list. #}
  {%- set unwanted_products = (
  'Homann',
  'Kühlmann',
  'Nadler',
  ) -%}

  {# This defines the list of offers we want to see. #}
  {%- set wanted_products = (
  'Sekt','Crémant','Brut','Champagner'
  'Äpfel','äpfel'

  {# Here, we define all variables we are going to use later on. #}
  {%- set ns = namespace() -%}
  {%- set ns.found_wanted=false -%}
  {%- set ns.product_list={0:0} -%}
  {%- set ns.product_list_current={0:0} -%}

  {# Now, let the magic happen. For each of the products available as discount items do: #}
  {%- for product in product_list_loop -%}
    {%- if product.price  %} {# This filters out entries without pricing details. #}
      {%- set ns.found_wanted=false  -%}
      {# If the product is on our positive list, we set a marker to have it added.  #}
      {%- for wanted_product in wanted_products %}

          {%- set ns.found_wanted=true  %}
        {%- endif -%}
      {%- endfor -%}
      {# Except when it also contains a string from things we don't want to see. 
         Then we have to remove that marker.
         (e.g.: we want to see Salat but not Homanns Fleischsalat as it is gross.) #}
      {%- for unwanted_product in unwanted_products %}
        {%- if product.product|contains(unwanted_product) -%}
          {%- set ns.found_wanted=false  %}
        {%- endif -%}
      {%- endfor -%}
      {# This is when we finally figured out whether we want to have 
         the current product on our result list or not. #}
      {%- if ns.found_wanted == true %}
        {# This is to add the first item to the empty list. #}
        {%- if ns.product_list_current == ns.product_list-%}
          {%- set ns.product_list = {product.product: product.price.price} -%}
        {%- else -%}
          {# This is for everything else. Looks a bit weird as 
          Home Assistant does not seem to suppport the comfy way. #}
          {%- set ns.product_list_current = {product.product: product.price.price} -%}
          {%- set ns.product_list = dict(ns.product_list.items(), **ns.product_list_current) -%}
        {%- endif -%}
        {%- set ns.found_wanted=false  -%}
      {%- endif -%}
    {%- endif -%}
  {%- endfor -%}

  {# Finally, we print out the whole thing in alphabetic order. #}
  {% for key,value in ns.product_list|dictsort %}
  {{ key }}: {{ value }} €
  {%- endfor -%}

For completion, here's a screenshot:

[Maxklos]

the cool card from @KrizzeOne doens't work anymore. We only get the current "price", not the old "regularPrice" . here is an updated card:

# **Obst und Gemüse**
|            |        |       |
| :------------: |:------------- | -----:|
 {%- set product_list_loop =  state_attr('sensor.rewe_4040708', 'discounts') -%}

{%- for product in product_list_loop -%} {% if 'obst-und-gemuese' 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 -%}
