I need some help with this one.
I made a script to make it easier and more consistent to generate notifications. It exposes a bunch of the options through fields. Generally that works, but I’m having issues passing an action to the script. I can’t figure out how to format the action data so it’s passed correctly to the script.
This first notification is the goal, however the second is what I’m getting when I try to pass the same data through a script using fields.
Here’s a conventional notification that works.
action: notify.mobile_app_a
metadata: {}
data:
title: >-
Time to Go in {{
states('sensor.countdown_to_next_departure_calendar') }}!
message: >-
Start Time: {{
as_local(as_datetime(states('sensor.next_location_start'))).strftime('%H:%M')
}}<br> Travel Time: {{
states('sensor.travel_time_to_next_appointment') }} <br> Address:
{{ states('sensor.next_location') }} <br> Appointment: {{
states('sensor.next_location_summary') }}
data:
actions:
- action: URI
title: Open in Google Maps
uri: >-
https://www.google.com/maps/dir/?api=1&destination={{states('sensor.next_location')
| replace(' ', '+') | replace(' ', '+') }}
enabled: true
This however doesn’t work (there is no “open map”) on the notification.
action: script.notification_script
metadata: {}
data:
device_to_notify: a
visibility: public
sticky: false
persistent: false
importance: high
priority: high
alert_once: false
include_time: false

{{ states('sensor.next_location') }} <br> Appointment: {{
states('sensor.next_location_summary') }}
