added a dedicated Lovelace bit to the script, which doesn’t use the formatting codes (Markdown card doesn’t handle these at all, so looks a bit silly) One can use markdown code in the card definition, but there’s not much use with this card.
Lovelace output:
btw @petro,
I’ve used your template for the template card, made it multiline and use state_attr(), but the list isn’t using the \n after each component.
this is perfect (so I know the cards first use in my setup works…):
but then this shows:
using this code:
- type: custom:card-templater
card:
content_template: >-
{{ "<details>\n" + state_attr('sensor.mqtt_hub_config','components') | sort | join('\n') + "\n</details>" }}
title_template: >
{{state_attr('sensor.mqtt_hub_config','components')|length}} Components Loaded
type: markdown
entities:
- sensor.mqtt_hub_config
entering that exact details template in dev-template show the correct format:
would that be a card issue, or a template issue…
anyways here’s the adapted python_script for use in lovelace and a markdown card:

# @123 and @apop pointed to the rest sensor, and made that availabe in Lovelace
# @petro had a great hand in creating the script
# thanks for joining in on a great HA community!
