Automation how to include folder

hello guys after having issue with none running HA … i finally got one…

do you guys have any example for configuration setting for using my old automation… i tried both of this

automation: !include_dir_merge_list automations

and

automation old: !include_dir_merge_list automations

with out success

I use:

automation old: !include_dir_list automation/

And then in there each file looks like:

alias: 'Test notify'
initial_state: 'on'
trigger:
  - platform: time
    at: '14:00:00'
action:
  - service: media_player.play_media
    data:
      entity_id: media_player.office, media_player.family_room, media_player.living_room
      media_content_id: http://pi3.family:8123/local/sounds/wind_chime.mp3
      media_content_type: music

thank this one works
