What is the template syntax for populating an entity with multiple entries from a sensor?

Configuration
1

I’m attempting to display multiple news stories using a max7219 matrix display using the feedparser custom component and I can select a single or random entry using


{{states.sensor.news_feed.attributes.entries[(1)]['title']}}

{{states.sensor.news_feed.attributes.entries[range(1,10) | random]['title']}}

and populate an input_text entity but what is the syntax for all the entries or a range of entries from the sensor?

I’m aware of the 255 character limit of input_text entities.

Use colons (:) to define how to slice the array/list and use map() to filter the desired attribute:

Titles of all entries:

{{state_attr('sensor.news_feed','entries')|map(attribute='title')|list}}

Titles of the first 5 entries:

{{ state_attr('sensor.news_feed','entries')[0:5]|map(attribute='title')|list }}

Titles of the last 2 entries:

{{ state_attr('sensor.news_feed','entries')[-2:]|map(attribute='title')|list }}

That’s weird. It works in the template designer but won’t pass HA yaml checks.

data:
      value: '{{state_attr('sensor.news_feed','entries')|map(attribute='title')|list}}'

Giving the error:
"can not read an implicit mapping pair; a colon is missed at line 11, column 94:
… attribute=‘title’)|list}}’

You need " on the outside of the template since there are ' on the inside.

Thanks. That works now.
