Home Assistant - Automatically turn on / turn off bluetooth on your smartphone

Good sunday guys,

In this article we saw how to turn on / turn off manually the bluetooth on your smartphone.

Today we'll learn how to create an automation to do this for us.

Use case

Your smartwatch is connected via bluetooth to your smartphone but, if for some reason you don't have the smartwatch on your wrist, keeping bluetooth enabled on your smartphone is useless as well as probably a cause for an undesired battery's consumption.

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. The companion app must have the bluetooth connection sensor enabled.
4. The companion app must have the permissions to modify the bluetooth connection (turn on / turn off).

Home Assistant code / procedure (yaml)

Add the entity sensor.yoursmartphone_bluetooth_connection to your dashboard.

This entity provides the attribute connected paired devices that refers to the list of paired devices that are currently connected:

When the smartwatch is not connected to your smartphone the list will be empty.

Taking into the account the behaviour described above, we can configure an auotmation to automatically turn off the bluetooth according to this trigger.

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

alias: Smartphone - Automatically disable bluetooth if not connected to my smartwatch
description: Smartphone - Automatically disable bluetooth if not connected to my smartwatch for one minute
trigger:
? - platform: template
? ? value_template: >-
? ? ? {{state_attr("sensor.yoursmartphone_bluetooth_connection",
? ? ? "connected_paired_devices") == [ ]}}? ?
? ? for:
? ? ? hours: 0
? ? ? minutes: 1
? ? ? seconds: 0
? ? ? milliseconds: 0
condition: []
action:
? - service: notify.mobile_app_yoursmartphone
? ? data:
? ? ? message: command_bluetooth
? ? ? data:
        command: turn_off
mode: single        

Some specifics about the code above

1. The trigger is based on a template.
2. To filter out quick and multiple bluetooth disconnections, the trigger must be true for 1 minute (you can set any value of course).
3. When the automation has fired, the action will turn off the bluetooth via a notification command. If you have updated your Android APP to the latest 2022.8 version, you must use command in place of title.
