Home Assistant - Stop streaming on Google Home speakers when not home

Hi everyone,

Today I would like to introduce the following automation, which is very useful especially when you leave your home and are in a hurry.

Use case

You are getting ready to go out and you are streaming music on the google home you have at home.

It's late. You go out but you forget to stop the music.

Software configuration

1. Home Assistant. I'm currently running version?2022.8.0
2. Mobile App integration?configured in Home Assistant. This integration allows Home Assistant mobile apps (Android / IOS) to integrate with your Home Assistant environment.
3. Within the configuration.yaml file set the coordinates (latitude/longitude) of your home location as well as the elevation in meters.
4. Google Cast integration?configured in Home Assistant. This integration allows you to control your google devices for streaming (chromcast) as well as audio (nest audio) via Home Assistant.
5. A familiy group like this one below has to be defined within the groups.yaml file in order to manage all the people at home as one entity:

family:
? entities:
? ? - person.A
? ? - person.B
	- person.C        

The state of the entity group.family will be:

• home when at least one of the defined person is at home.
• not_home when all the defined people are outside home.

Home Assistant code (yaml)

This is the piece of code -?Automation?- you have to write down:

alias: Position - Tunrn off google home
description: Turn off google home if familiy group is not_home
trigger:
? - platform: state
? ? entity_id: group.family
? ? from: home
? ? to: not_home
? ? for: "00:00:15"
condition: []
action:
? - service: media_player.turn_off
? ? data: {}
? ? target:
? ? ? device_id:
? ? ? ? - device_A
? ? ? ? - device_B
? ? ? ? - ....
? ? ? ? - device_N
mode: single
        

Some specifics about the code above

1. The state home / not_home of the entity group.familiy is based on the position provided by each device_tracker.[nameofthesmartphone] entity.
2. To avoid unuseful changes state, the trigger needs to be true for 15 seconds before executing the actions.
