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.

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.

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 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

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.

I used a ton of AddOns, really practical because they also embed themselves easily into the rest of Home Assistant. I would go for the HA OS. But I also do wish there was a AddOn to install random docker images.

I've run both, and the OS version is much more stable and easier to keep running. Whether you use an rpi or a VM, use the dedicated OS and save yourself the heartache of trying to get your hardware working with docker.

You can also run hass os in a vm then you still get add-ons, from what I understand

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 started out running HA in a docker container on a NUC (everything configured in a docker compose file). Documentation around everything was pretty poor at the time (I'm not sure if this has improved since then), so I ended up feeling too confused on where to even begin expanding from vanilla HA.

I ended up picking up a RPi 4 (and SSD and enclosure) and have been happily running HA OS since then on the Pi. If that ever fails on me, I may go back to a docker instance.

I'd recommend you try whichever is the most convenient first (probably the docker approach, unless you already have the Pi on hand). Give it a month or two, try to setup up a few things you're interested in, and then decide if you're satisfied with that setup or want to try the other option.

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

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.

You can also run hass os in a vm then you still get add-ons, from what I understand

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’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.

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

I have HA running in docker on a Pi 3 and Z-wave JS running in another on the same Pi. Added a purpleair integration for outdoor air quality, national weather service, some local sensors, and sql to get data from another node. People have made me paranoid about SD card failures, so I regularly image it to my main server. I mostly use HA to visualize environmental data, but it also runs the lights in a hydroponic farm and the house during vacations, via z-wave outlets. Have not tried to integrate it with google or amazon.

The only inconveniences I've found with docker is that you can't restart HA from its web interface and, if you update regularly, old images quickly fill a smaller card, so you have to remember to purge.
