Hi everybody!
Using a little imagination I have been able to “integrate” my bluetooth headphones into Home Assistant and give them some extra features:
- Headphone status monitoring (on/off)
- Automations based on the person and/or device in use
- Automatically start music playback
- Notification and remote shutdown of the headphones, when I leave them on.
You can find full guide here. I hope someone can find it interesting 
Also i would appreciate some help with this:
- I am trying to find the Android intent to ‘power off’ my Sony headphones, as it is possible to do it from the app. I couldn’t achieve it yet.
- I wonder if there is any way to report to HA the battery level of the headphones.
Thanks!
