Presence Input Boolean Sensor Template

I use an Input Boolean switch for presence and a template to change from an On/Off Switch to Home/Away I’m wondering if there’s a way to pull Zone information into the template.

- platform: template
  sensors:
    annie_home_away:
      value_template: "{% if is_state('input_boolean.annie_home', 'on') %}Home{% else %}Away{% endif %}"

Top “Annie” Is a regular device tracker
Bottom is the input Boolean switch that I’d like to have include “At Greenfield School”

I’m not 100% sure if I understand correctly what you intend to do.
Boolean means yes or no, which might be translated to away or home, but a specific location is not a valid boolean value. So you probably want to use a template sensor to display the location of that person.
