Cant get image to send in ios notication - help :)

If you want a static camera snapshot image instead of a streaming one, make a “snapshots” directory under the “www” directory where your config is then use:

action:
- service: camera.snapshot
  data_template:
    entity_id: camera.front_door_camera
    filename: "/config/www/snapshots/front_door_camera_{{ trigger.to_state.last_changed }}.jpg"
- service: notify.ios_iphone
  data_template:
    message: 'Someone has pressed the door bell at {{now().strftime("%H:%M %d-%m-%y")}} '
    data:
      attachment:
        content-type: jpeg
        url: "https://hass.yourdomain.com/local/snapshots/front_door_camera_{{ trigger.to_state.last_changed|urlencode }}.jpg"
      entity_id: camera.front_door_camera

Note that /local/ maps to the “www” subdirectory of your config directory.
