HA on Synology DSM 7.2, Docker 2023.12: Error during setup of component bluetooth


I set up HA for the first time on my local environment (Synology DSM 7.2 + Docker). It’s running but showing errors regarding bluetooth all the time. I failed to understand and fix it.

I read through discussions (1, 2) regarding bluetooth support of HA when using docker and/or Synology DSM. This seems to be a tricky thing in general…
However, I don’t have any bluetooth device on my host machine (RS1221+) and I don’t plan to use BT in my HA. I don’t think I should ignore these errors, e.g. because installation of Shelly integration fails because of “Failed dependencies bluetooth” although Shellys can be accessed and should be supported without bluetooth.

“io.hass.base.version”: “2023.10.4”,
“io.hass.version”: “2023.12.1”,
“org.opencontainers.image.version”: “2023.12.1”
