Presence Based Automation

Configuration
6

Its shown that way in the getting started documentation (scroll down to state trigger)

Also, I found out today you can have multiple triggers under an automation.

for example:

trigger:
  - platform: zone
    entity_id: device_tracker.mine
    zone: zone.home
    event: leave
  - platform: zone
    entity_id: device_tracker.hers
    zone: zone.home
    event: leave
