Custom:light-entity-card inside a conditional card

Could someone shed some light on how to get the WLED ‘custom:light-entity-card’ to display in a conditional card?
Below is my code but not getting any results.

cards:
  - card:
      entities:
        - light.smart_light1
      type: 'custom:light-entity-card'
    conditions:
      - entity: input_select.lights
        state: NEO Lights
    type: conditional
title: Room Selection/Schedule
type: vertical-stack

cards:
  - card:
      entity:
        - light.smart_light1
      type: 'custom:light-entity-card'
    conditions:
      - entity: input_select.lights
        state: NEO Lights
    type: conditional
