I’ve been playing around with this a bit (with the help of ChatGPT, this post and this post) and ended up with this:
[
{% set entities_str = states('sensor.individual_lights') %}
{% set entities = entities_str[1:-1].replace("'", '"').split(', ') %}
{% for e in entities %}
{
"type": "custom:decluttering-card",
"template": "illumination_light-card-single",
"variables": "{
'- Light': {{ e.strip('"') }} }",
},
{% endfor %}
]
the reason for all the code at the beginning is because state_attr('sensor.individual_lights') is None.
the outcome in developer tools Template looks very similar to yours:
But when I put this into my card, auto-entities sees each line as a separate entity.
My Auto entities card
type: custom:auto-entities
filter:
template: |
[
{% set entities_str = states('sensor.individual_lights') %}
{% set entities = entities_str[1:-1].replace("'", '"').split(', ') %}
{% for e in entities %}
{
"type": "custom:decluttering-card",
"template": "illumination_light-card-single",
"variables": "{
'- Light': {{ e.strip('"') }} }",
},
{% endfor %}
]
include: []
exclude: []
show_empty: false
card:
type: custom:layout-card
layout_type: custom:grid-layout
I feel like we’re suuuuper close, but something isn’t working out yet
