Entities Card- suffix?

How do I get my suffix string to show?

type: entities
entities:
  - entity: sensor.windstation_temperature_c
    name: Temperature (C)
  - entity: sensor.windstation_temperature_f
    name: Temperature (F)
  - entity: sensor.windstation_humidity
    name: humidity
    suffix: "%"
  - entity: sensor.windstation_wind_direction
    name: wind direction
  - entity: sensor.windstation_windspeed
    name: wind speed
    suffix: mph
title: Windstation

windstation card

Suffix is only available for the Attribute special row type.

What’s an “Attribute special row type”?
That’s where I found the suffix:, but what is or how is the “Attribute special row type” different from any other use of the entities card?

The entities card can show entity states on each row but it also has the ability to show other things, like attributes, buttons, dividers, sections, etc…

The suffix option is listed under the attribute special row, not the entity state row. Hence you can’t use it for bog standard entity states, only when showing attribute states.

Look closely at the documentation I linked to, suffix is under the attribute type. That is the only place you can use it. The options for entity rows are listed above that. Those are the only ones you can use for an entity.

Thanks- that makes it clearer.
