Hopefully solved, although clumsily, and I’m still curious to know of a more elegant way (?SSH files into one’s user’s …/Media/share/ directory perhaps)…
- had to install drivers for ntfs first
- mount the drive
- copy files to the the yunohost shared media folder
- by the time this was done homeassistant could “see” miniDLNA
$ sudo apt install ntfs-3g
$ sudo mount /dev/sdb1 /media/ssdmedia
$ sudo cp -r /media/ssdmedia/ /home/yunohost.multimedia/share/Music
I shall have a play when (if!) I get some proper free time (have to fix the UPS first!) and see if it does what I want… I can’t obviously see how to get homeassistant to send music to the 3.5mm minijack audio-out of the server (PC).
Will report back here with outcome.
