Google Calendar WebUI Trigger

I’ve successfully set up google calendar as sensor and can see whether it’s off or on based off of events in my calendar. How do I set the trigger in an automation from the WebUI, is it numerical set to above 0 for an “on” state? Additionally will the sensor trip if the event is for 1 minute and the polling happens after the event ends?

You can set the trigger to use state, from “off” to “on”

I have it like this (extract from automations.yaml)

- action:
  - data: {}
    data_template:
      message:  Put Trash {{states.calendar.trash.attributes.message}} out
      target: '+99987654321'
    service: notify.fbmessenger
  alias: Trash Reminder Notification
  condition: []
  id: '1514806795236'
  trigger:
  - entity_id: calendar.trash
    from: 'off'
    platform: state
    to: 'on'

Thanks, I didn’t understand the syntax, the trigger is when a sensor goes from on to off or vice-versa. I also kept on putting the on/off values in quotes
