Hi all, I'd like to make an automation (or rather a templated sensor) that reflects whether today's calendar has any events matching a pattern (whether I am on the schedul to cook dinner). I know how to do this on a one-off basis using a service call and filtering the response; and I could certainly run the trigger on a time interval, but I feel the natural way to do this is when the calendar itself is updated. I am using Google Calendar integration. Is there a generic home assistant event that gets fired when an entity is updated (not a "calendar event" but an event signal)? Thanks for any ideas.🗓️

I'm going to guess not. I have a local calendar, started listening to all events in developer tools, and on adding a new item to the calendar I found no event fired.
maybe google calendar has one that local calendar doesn't, but you'd have to test and see maybe

thank you for that check!
i'm still hoping that polling based integrations emit events on their updates, but my searching of the code hasn't shown me anything

There is an event for it (state_reported) but you can’t use it in an event trigger, by design.

Thanks for the idea @final wolf , but the following trigger did not fire:
entity_id:
- calendar.family
attribute: last_reported```
and the folowing template renders as `null`:
```{{ state_attr("calendar.family", "last_reported") }}```
