Why this helps
A changed appointment can quietly invalidate the transit timing you checked earlier.

- Recheck the departure schedule using updated event details.
- Keep schedule follow-up close to the calendar change.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Bart once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis to review changed event fields and look up a BART departure schedule when the event time affects a trip, reporting missing origin or destination station codes.
- 4Choose Event Updated as the trigger and select where run reports should go.
- 5Test it with one real event update that changes a trip-relevant time.
Questions about this workflow
Does this know the previous trip plan?
The Event Updated trigger returns the changed fields with previous and new values, but it does not provide a BART trip history. Include the relevant station codes in the event details or instruction if they are not available in the update.
Will it recalculate every event change?
The automation can be instructed to look up a schedule when changed fields affect trip timing. The event provides the specific changed fields, so unrelated edits can be ignored.
