Auto-entities & time-picker-card?

Configuration
1

I’m attempting to use the auto-entities card to automatically add entities to the time-picker-card. I’m failing though.

This is the closest I’ve gotten, but only if I add each entity_id individually, with different cards:

type: 'custom:auto-entities'
card:
  type: 'custom:time-picker-card'
  entity: input_datetime.school_abby_extra
filter:
  include:
    - entity_id: input_datetime*

this seems more like it should work…:

type: 'custom:auto-entities'
card:
  type: 'custom:time-picker-card'
  layout:
    name: inside
    align_controls: center
filter:
  include:
    - input_datetime.school_*

but gives this error:
