Google Calendar - Notifications based on Event with wildcard naming?

1

Hi All,
Now that IFTTT has jumped the shark, I’m looking to have Home Assistant notify me when certain events happen in my Google Calendar. These events have a common prefix.

I have set up Google Calendar in Home Assistant, works like a charm, pulls in events, can add them via Home Assistant etc.

What I’m after is a way to wildcard the condition in an automation, so that if I set up event with the prefix ‘Birthday - *’, eg Birthday - Joe Bloggs’ as an all day event, I can get notified of the calendar event.

I can get notifications for events that EXACTLY match the ‘message’ that I feed it. I’d prefer to not set up a new automation for every friend and family birthday if I can avoid it…

Then the icing on the cake would be to have the notification dynamically display the event title (eg ‘Birthday - Joe Bloggs’).

Please let me know if I’ve missed something super obvious :smiley:

Thanks in advance.

In your Google Calendar you create a “sub-calendar” that you can name “Birthdays”.
Then in your Google Callendar you add all the birthdays as an all-day event and select calendar “Birthdays”. So, the birthdays of Tom, Dick, Harry and Mary all have the sub-calendar “Birthdays”.
The “sub-calendar” “Birthdays” will be an Entity in HA that you can use for Automations.

alias: Birthday Calendar Notifications

trigger:
  - platform: calendar
    event: start
    entity_id: calendar.google_example
condition:
  - "{{ trigger.calendar_event.summary is search('Birthday -') }}"
action:
  - service: notify.example
    data:
      message: "{{ trigger.calendar_event.summary }}"

Thanks, that’s perfect and did the trick for me :smiley:

Thanks, I wanted to avoid migrating all events from one calendar into another. Events exist in a shared calendar and it would be challenging to convince the other contributors to add things elsewhere.
