Alexa "I'm Home"... well sort of

This started from a need to control my Schlage Encode WiFi lock which is not supported by HA. I have Alexa integrated and it does support the lock, works quite well actually. Problem is Alexa has no way to track presence so I could not tell it to lock up if nobody was home just in case we forgot.

So how did I trick Alexa… with a binary sensor.

I have “People” in the configuration menu configured with device trackers for both my wife and I. I used the “person.name” entities it creates to create the sensor.

binary_sensor:
  - platform: template
    sensors:
      people_home:
        value_template: >-
          {{ is_state('person.faith', 'home')
             or is_state('person.vinny', 'home') }}

This creates an entity called “binary_sensor.people_home”. Problem is Alexa will not recognize this as it is so another change. From the configuration menu all the way at the bottom using “Customizations” you need to change the “binary_sensor.people_home” device class to “window”… I know sounds crazy but you can now present it to Alexa and it knows what a window is… “Closed or Open” = “Home or Not Home”

From there Alexa now knows if we are or are not home. Because I only created one sensor with both people it needs us both to be home or gone for a state change, but that was all I needed. You can create individual sensors if you need to. From there I was able to write an Alexa routine to lock up for me in case we forgot but I’m sure there are a lot of other possibilities this can be used for.

Do you want when you’re come home Alexa will greet you?

If so, I created 2 input_booleans:

kay_home_manual:
  name: "Kay"
  initial: on

peter_home_manual:
  name: "Peter"
  initial: on

Then 2 automations. When device_trackers are on then turn on the input_boolean.
(When 1 device_tracker become offline I’m still at home. Otherwise all are off.

Here it create a group that will be used in the automation later on to greets 1 of 2 or both persons:

This will use group to see if 1 person or 2 persons went home… and Alexa will greet us in person or both
