- Home Assistant Supervised: The host system must run BlueZ, and the D-Bus socket must be accessible to Home Assistant **inside** the container.
- Home Assistant Core: The system must run BlueZ, and the D-Bus socket must be accessible to Home Assistant.
### Additional details for Container installs
{% details Making the DBus socket available in the Docker container %}
For most systems, the Dbus socket is in `/run/dbus`. The socket must be available in the container for Home Assistant to be able to connect to Dbus and access the Bluetooth adapter. When starting with `docker run`, this can be accomplished by adding `-v /run/dbus:/run/dbus:ro` to the command. If the Dbus socket is in `/var/run/dbus` on the host system, use `-v /var/run/dbus:/run/dbus:ro` instead.
{% enddetails %}
### Additional details for Container and Supervised installs
{% details Installing BlueZ %}
On Debian based host systems, the `sudo apt-get -y install bluez` command will install BlueZ.
{% enddetails %}
## Installing a USB Bluetooth Adapter
Some systems may not come with Bluetooth and require a USB adapter. Installing an adapter for the first time may require multiple restarts for the device to be fully recognized.
