Syntax for Harmony remote state in scene?

How do I go about adding a harmony state to my scene? I want to have a bedtime routine that turns off any current Harmony activities.

- name: Bedtime
  entities:
    remote.living_room: off

This doesn’t work. I know that a switch for each activity is created. I was hoping to avoid having to include each activity switch into the scene and instead just have a catch-all turn off.

Here’s the correct notation for a scene. Don’t know if it’ll work, but it should.

- name: Bedtime
  entities:
    remote.living_room: 
      state: off
