Quick help with a device trigger

I am using iCloud /Itunes for device tracker with a few zones. Well one of my zone is so close to Home that when my wife moves into it, the trigger i have is trigger by state changes to “not_home” never goes off, instead it simply switches to the zone name. If I get rid of the zone or she travels somwhere far enough away it will trigger on “no_home”

Can I set a from trigger with out a to like this
- platform: state
entity_id: device_tracker.iphone
from: ‘home’

Yes, that will work.
