Bluetooth_tracker not updating to "not_home"

I’m trying to make my first automations with tracking.
I got the Hass.io updating my precens using BT as soon as I turn it on on my phone.
The problem is that it never changes state to not_home when i turn BT off.
What have I missed?

config.yaml
device_tracker:

  • platform: bluetooth_tracker
    interval_seconds: 60
    consider_home: 180
    track_new_devices: yes

autom.yaml
alias: Welcome Calle
trigger:
platform: state
entity_id: device_tracker.carls_iphone
from: “not_home”
to: “home”
action:
- service: media_player.volume_set
entity_id: media_player.vardagsrum
data:
volume_level: “0.6”
- service: tts.google_say
entity_id: media_player.vardagsrum
data:
message: “Welcome home Carl!”
