Automation issue

Configuration
1

For some reason when I turn my plug on for my tree my automation is not running. Here is my code:

automation:
  -  alias: "Fireplace"
     trigger:
       - platform: state
         entity_id: switch.tree
         from: 'off'
         to: 'on'
     action:
       service: media_player.play_media
       data:
         entity_id: media_player.living_room
         media_content_id: http://192.168.1.187:8123/local/video.mp4
         media_content_type: video/mp4

Show us the configuration for switch.tree

Is it a zwave device? Some zwave devices don’t report status back to HASS.

Also - if you trigger the automation manually via the UI, does the media play correctly?
