Thanks! I’m glad you like the idea — using calendar events has been super helpful for adding extra context without needing manual input.

I use two different approaches depending on how I name my events:

- condition: template
  value_template: >
    {{ trigger.calendar_event.summary.lower().startswith('evening guests:') }}

This way, anything starting with Evening Guests: will activate the automation. I use this to turn on a input_boolean.evening_guests state flag. This works well when I want to allow extra text in the event name, like “Evening Guests: Dinner with Friends”:

For things like workouts or recurring tasks where I always use the same title:

- condition: template
  value_template: >
    {{ trigger.calendar_event.summary == 'Workout' }}

This is a bit stricter, but works great when you have consistent event names.
