I am seeking help with syntax in the dashboard card.
My aim is to generate as many cards as there are entries in the attribute. However, I am stuck with syntax.
# Create swipable cards from the RSS feed
- type: custom:swipe-card
cards:
{%- set j = state_attr('sensor.rss_feed','entries') -%}
{%- for image in j -%}
{%- if state_attr('sensor.engineering_feed','entries')[j]['image'] is defined %}
{%- set image_url = state_attr('sensor.rss_feed','entries')[j]['image'] %}
{%- if image_url %}
- type: markdown
content: >
<img src="{{ image_url }}" />
{%- endif %}
{%- endif %}
{%- endfor %}
```
