Home Assistant fix for Home/Away location tracking

HA_HomeAway_fix

##############
# Part 1: create "distance" sensors in configuration.yaml, one for each person
# The two of us have phones running the HA app, so these are the ones used.  
# This creates helper template devices that provide current distance to each person
sensor:
  - platform: template
    sensors:
      distant_to_gary:
        friendly_name: "Distance to Gary"
        unit_of_measurement: 'mi'
        value_template: "{{ distance(state_attr('zone.home', 'latitude'), state_attr('zone.home', 'longitude'), state_attr('person.gary_morris', 'latitude'), state_attr('person.gary_morris', 'longitude'))|round(1) }}"

##############
# Part 2: 
# Using the HA interface, create Input Boolean helpers.  One per person.  
# Mine are called "Gary is Home" and "Gabriela is Home" 
# Any automations you have can then trigger off these input booleans.


##############
# Part 3: this is an automation yaml file that keeps the Input Boolean helpers updated.
# Create one of these for each person being tracked.
# Change the names of devices and SSID's to match your WiFi network.
