This BluePrint will monitor a person or persons, and when they 'enter' or 'leave' the zone you pick, it will trigger an action.
I use this BluePrint to follow family members around during their day so that the family members at home know where their loved ones are.
The monitored areas need to be set up as zones in Home Assistant. SEE: HA ZONES LINK

The person needs something monitoring their location. I use Life360, but the Home Assistant App running on their phone will also work. There are likely other location monitoring methods but I am not aquainted with any of them. SEE:

📩 There is not an official version control system for Blueprints. However I have found something that comes pretty close. It is not perfect, but for MOST Blueprints, it does just fine. I encourage you to check this script out and use it to easily check if I have updated this blueprint. 🔗 koter84 Blueprint Update Script
