Trouble formatting time with custom:custom:multiple-entity-row (HACS)

Configuration
1

I’m trying format a time, but there is no change to the formatting.

type: entities
entities:
  - entity: light.porch_light_2
    type: custom:multiple-entity-row
    secondary_info: >-
      Last OFF: {{ state_attr('automation.turn_off_outside_lights',
      'last_triggered') | timestamp_custom('%H:%M') }}
title: Second
state_color: true![Screen Shot 2021-06-09 at 4.53.03 PM|690x233](upload://iNdy8Ti5btblTmCEN4URDbBA3oG.jpeg)

Any ideas?

I figured it out. I’m get a string back from the state_attr call, not a date object. That string has to be parsed into a date and only then can be formatted:

type: entities
entities:
  - entity: light.porch_light_2
    type: custom:multiple-entity-row
    secondary_info: >-
      Last OFF: {{ state_attr('automation.turn_off_outside_lights',
      'last_triggered').strftime('%Y-%m-%d %H:%M:%S') }}
title: Second
state_color: true
