The goal of this tutorial is to pair arbitrary bluetooth speaker with the Home Assistant (HASSO) to be able to hear notifications & TTMs

What was used during the installation:

• Proxmox
• Home Assitant (Supervisioned version) (I've being using currently Home Assistant 2023.6.3 -> Supervisor 2023.06.4 -> Operating System 10.3)
• any bluetooth spearker without auto-inactivity auto-shutdown funciton. I've used Xiaomi Mi Compact Bluetooth Speaker 2 (XMYX02YM)
• 

I. Connection:

1. Identify your BT speaker's BT MAC Address & BT Name
2. Make sure that Proxmox - HA VM as Audio device added (for example: device=intel-hda, driver=none)
3. Install SSH addon into the HA and configure it
4. Switch off yout BT speaker
5. Loging into the HA using termina: login@IP_Adress
