Notification with a data_template

Configuration
1

I made a binary sensor for the network connectivity for my NAS. This binary sensor is based on the ping platform. It works as intended.
I tried making a data_template to send the notifications but that does not work.

action:
  service: notify.mobile_app_iphone_x_van_rutger
  data_template:
  {% if is_state("binary_sensor.synology_nas", "on") %}
    title: Message From Computer
    message: NAS is online
  {% elif is_state("binary_sensor.synology_nas", "off" %}  
    title: Message From Computer
    message: NAS is online
  {% endif %}

I hope somone can help me as i’m pretty new to this. Hope to learn a bit more.

Thanks you very much!

Templates can only go in a single field. You cannot template multiple fields. Jinja only returns a single field string. Also, you are missing the multi-line template identifier.

Example of single field

action:
  service: notify.mobile_app_iphone_x_van_rutger
  data_template:
    title: blah #<--- SINGLE FIELD
    message: blah #<--- SINGLE FIELD

what your stuff should look like

action:
  service: notify.mobile_app_iphone_x_van_rutger
  data_template:
    title: Message From Computer
    message: > #< THIS IS A MULTILINE TIMEPLATE IDENTIFIER
      {% if is_state("binary_sensor.synology_nas", "on") %}
        NAS is online
      {% else %}
        NAS is offline
      {% endif %}

optimized

action:
  service: notify.mobile_app_iphone_x_van_rutger
  data_template:
    title: Message From Computer
    message: >
      NAS is {{ 'on' if is_state("binary_sensor.synology_nas", "on") else 'off' }}line

Hi Petro,
is it possible to send a message with templated title?
i would like to see in the title the area_name of the entity that triggered the alarm:

service: notify.mobile_app_s21u_fl
data_template:
  title: Rilevato Movimento in {{ area_name('{{trigger.to_state.entity_id}}') }}
  message: {{ trigger.to_state.attributes.friendly_name }} <b>{{ trigger.to_state.state }}</b>

this is actually not working, it is back with ‘none’.

thanks
