I run my own a VM.

I was sceptical about running in a OS that I can’t run my normal updates and automations on but HA OS has been rock solid and easy. Plus you get a few more features

You can go supervised! You still have most of the operating system available to your needs and you can still use add-ons. I use it for years and it works like a charm

I’m running the docker version as I’m also using the rpi for other things, like imageview and pi hole. I don’t really miss addons, the only annoying thing is that most documentation assumes you’re running ha os.

But if you don’t plan to use it for anything else than HA, I’d go for HA OS.

I recommend HA OS. What happened to me is that I used docker, got everything set up how I liked it, then had to move over to HA OS when I needed a specific add on and didn’t have any other solution.

If you don’t already have a plan for other services, might not make sense to use docker, too.

HA OS is the way to go.

You don’t want to have to think about it. HA OS just works. You set it up and let it run.

There’s no sense in trying to kerfuffle other things into it. You don’t want to do too much on the Pi anyway because it’ll lower the responsiveness of Home Assistant slightly. If you want a server that does things, buy a separate NAS and run it alongside HA OS.

I definitely prefer HA in a VM, that way it can do its own thing and I won’t accidentally break something.

home assistant in docker is definitely not for the feint of heart! the networking requirements are actually quite intense, and really don’t map well to virtual networks like dockers uses

… among other issues

HAOS on a pi; i’ve tried the docker thing time and time again, and the next chance i get in blowing it all away and starting on real hardware again

I’d always run HAOS. When you need Docker containers which are not available as add-ons I would look for a machine that can run Proxmox so you can run a Docker VM and a HAOS vm in parallel.

There’s nothing that you can’t do with dooker that you can do with addons. Addons are marginally easier to setup but if you have technical skills, docker is also not a lot of work. You can use something like Portainer to get a similar easy interface. So I think it’s down to if you have the technical skills for docker.

I run ha supervised and I do both, but the system does complain that I do that.

Home assistant OS is also my recommendation. Add-ons are pretty important IMO. Plus for something I am planning to try and have 100% uptime and controlling my home smart devices I don’t want it containerized and at the mercy of docker.

Currently using 15 add-ons myself.

I think the pi isn’t a great value proposition anymore especially given the availability issues. I run HA off of proxmox installed on a nuc11 NUC11ATKC4 with a Celeron N5105, which set me back about $150 USD. It runs solid as a rock, with 2 cores and 8gb of ram, and enough left over to carve out an instance for running a local game server like Minecraft or Satisfactory when I like. You could do something like a pihole or a plex server instead, easy. Don’t let people tell you it’s hard to set up this way…there are well maintained scripts for installing and configuring proxmox and then HAOS afterwards. Took me like 15 minutes total of basically braindead pressing enter for ‘next’. The instance runtime has been completely uninterrupted except for updates for over 6 months now. I let a pi run my 3d printer but I think I’m done running any constant availability services off of one.

Running it on a bare Pi, HAOS, imho you get the most performance, and support if it goes wrong.

Running on more powerful hardware (x64 host), VM all the way. It’s so much easier when you can snapshot, move VMs around, and split out components when needed.

I run HA OS and from my experience updating and installing add-ons is seamless. Creating backups and restoring (had to replace a corrupt SD Card a while ago) was also no issue.
Add-ons I have installed

• Advanced SSH Terminal
• ESP Home
• Home Assistant Google Drive Backup
• VS Code Server
• Maria DB

HACS for a few integrations:

• YT Music Player
• Waste Collection Schedule

nothing too fancy.

I run a second Pi with an SSD for docker containers or native OS installs (gitea, drone-ci, pi-hole, etc.)

I’m running Supervised in Docker. I don’t know how I managed to do it but it wasn’t hard. I use addons, and also have other things running on my Pi

@unknowing8343

I used the fanciest possible setup with HA running in a Kubernetes cluster and its helper services likewise, but that’s severe overkill for most people unless they’ve got compute to burn and need/want/enjoy customizing the heck out of everything.

A Pi, even a Pi 4, isn’t compute to burn but also isn’t expensive enough to need other services on it to justify it. For what it’s worth, I’d suggest HA OS and dedicating the Pi to it.
