How to Install Home Assistant On Virtual Machine in TrueNAS Scale

1. Download TrueNAS vmdk from home-assistant.io

You can download from here https://www.home-assistant.io/installation/linux

2. SCP/SFTP the vmdk to TrueNAS, if you don't have VMs/src path, then create it

# scp haos_ova-9.3.vmdk admin@TrueNAS_IPAddress:/mnt/DATA-Pool/VMs/src

3. SSH Login as root to TrueNAS and convert the vmdk to raw img

# qemu-img convert -f vmdk -O raw /mnt/DATA-Pool/VMs/src/haos_ova-9.3.vmdk hassos.img

4. Create VM on TrueNAS Web Control then get Disk Zvol path and build zvol size 64G

My build path example is:

DATA-Pool/VMs/Home-Assistant-ib310

5. SSH Login as root and use dd to write the image file to your zvol

# dd if=hassos.img of=/dev/DATA-Pool/VMs/HomeAssistant-ib314
