Yep I’m off to do this now! Got it set up on Docker fine but then realised lots of missing functionality so going to redo it via virtualisation instead, otherwise no add-ons available and I’m wanting mqtt and Node Red!
EDIT: so in fairness really easy once I found that the OVA VM file is directly recognised by QNAP. I just downloaded it from Alternative - Home Assistant and then picked ‘import VM’ from Virtualisation Station, allocated 2 CPU and 2 GB RAM and then when I started it I was then able to browse to it and get HA up and running. Just as easy as a Docker container and now I’ve got the supervised version of HA installed
