Installing Home Assistant OS on Truenas Scale
2022-10-29 Update
There's a newer version of HAOS available, so the below guide has been updated to use that. The original used this:
Use wget to get the ova file:
wget https://github.com/home-assistant/operating-system/releases/download/6.6/haos_ova-6.6.ovaExtract the ova file using tar:
tar -xvf haos_ova-6.6.ova

Mostly taken from https://www.truenas.com/community/threads/home-assistant-vm-on-scale.91058/post-666766 and cleaned up.
Make sure to use a location on your data pool as a working directory, don't use any system directory. I made a hass folder on my data pool plex-media:
cd /mnt/plex-nas/plex-media/hass
Use wget to get the ova file:
wget https://github.com/home-assistant/operating-system/releases/download/9.3/haos_ova-9.3.ova
Extract the ova file using tar:
tar -xvf haos_ova-9.3.ova
Convert the vmdk to a raw image file, I had to use the full working directory for the source:
qemu-img convert -f vmdk -O raw /mnt/plex-nas/plex-media/hass/home-assistant.vmdk hassos.img
Create a Zvol using the TrueNas Scale GUI - Be sure to make it large enough for dd to complete, I used 35 Gib.
Use dd to write the image file to your zvol
dd if=hassos.img of=/dev/plex-nas/home-assistant
Create a virtual machine using the gui and attach the zvol you just created as the hdd.
Minimum recommended assignments:
- 2GB RAM
- 32GB Storage
- 2vCPU
All these can be extended if your usage calls for more resources.
