On/Off state for lights that do not have brightness attribute?

[ghost]

Is there a way to display "state" instead of brightness %?

Current yaml for that device:

type: custom:big-slider-card
entity: light.game_room
show_percentage: true
name: Main Light
attribute: brightness
icon: mdi:chandelier
bold_text: true
min: 0
max: 100
colorize: false
min_slide_time: 2
icon_color: '#EEB76B'
height: 90
background_color: var(--ha-card-background)
