Breaking My Smart Home Fixed Everything

Published at : 18 Dec 2025

I listened to the Home Assistant nerds out there and it caused me a whole night of pain and suffering! Luckily it all worked out in the end and now my smart home system is more indestructible than ever.

If you just want to install Home Assistant on a Mini PC, this video was super helpful: https://www.youtube.com/watch?v=iE0b8rjVglA

If I would have just realized that my USB extender was stopping my Mini PC from booting at all, then updating Home Assistant would have been no problem. But it forced me to try Proxmox, so a blessing in disguise.

If you want to install Proxmox here is a video by Mark Watt Tech, which was great overview but I ended up doing things a bit different: https://www.youtube.com/watch?v=PrKQkI53xys

Here's what I did. I downloaded Proxmox: https://proxmox.com/en/downloads

Then I wrote the ISO image to a flashdrive following the directions: https://pve.proxmox.com/wiki/Prepare_Installation_Media

Once Proxmox was installed on the Mini PC this guide was super helpful to get HA up and running on Proxmox: https://forum.proxmox.com/threads/guide-install-home-assistant-os-in-a-vm.143251/

I ended up giving my Home Assistant VM 8GB of RAM and allocated all 4 cores. You can always edit this after. Just go to the Hardware tab, change it, then fully shutdown the VM to apply the changes.

Then I created a backup of the VM of HA using Proxmox following this guide: https://smarthomescene.com/guides/how-to-backup-home-assistant-in-proxmox/

After it was all up and running, Proxmox was throwing some errors because it can't update using the enterprise repo and I needed to switch it to the community one. Here is how to fix those errors: https://www.youtube.com/watch?v=5AumO9AKKB0
