Show brightness as text value for every light

I want to see every light along with the brightness value. I’m using auto entities to give me the following. How can I get a second column with the light’s corresponding brightness value?

card:
  show_icon: false
  title: light.*
  type: entities
filter:
  include:
    - entity_id: light.*
show_empty: false
type: 'custom:auto-entities'

In this post someone suggests using a template sensor to read the lights brightness attribute. I’m not sure how that was implemented. I know how to create template sensors, but don’t know how you would implement it with a wildcard.
