Should you’re planning a brand new Residence Assistant setup, one of many first selections you’ll face has nothing to do with Zigbee, automations, or dashboards.
It’s this:
Must you run Residence Assistant on devoted {hardware} or inside a digital machine (VM)?
Fortuitously, there isn’t a flawed reply.
Residence Assistant runs nicely in each environments. Whether or not you put in it on a purpose-built equipment like Residence Assistant Inexperienced, a Raspberry Pi, a mini-PC, or inside a Proxmox VM, you possibly can construct a quick, dependable sensible house.
The higher query is that this:
How do you wish to keep, defend, and develop your system over time?
That’s the place the choice turns into extra attention-grabbing.
I’ve run Residence Assistant for years and at the moment run Residence Assistant Working System (HAOS) inside a Proxmox digital machine. Whereas I usually want the VM method, I don’t suppose it’s robotically the perfect reply for everybody. Let’s stroll by the tradeoffs.

What Do We Imply by Devoted {Hardware} and a VM?
Earlier than evaluating them, it helps to outline what we imply.
Devoted {Hardware}
Devoted {hardware} means Residence Assistant runs on a tool devoted primarily to Residence Assistant.
Frequent examples embody:
That is typically the best method. The system behaves extra like an equipment than a server. You put in Residence Assistant, configure it, and largely neglect concerning the underlying platform.
Digital Machine (VM)
A VM method means Residence Assistant runs inside a digital machine hosted on one other system.
Frequent hosts embody:
- Proxmox
- ESXi
- Hyper-V
- Unraid or comparable virtualization platforms
On this setup, Residence Assistant shares {hardware} with different workloads. For instance, my Proxmox server runs Residence Assistant alongside different companies and containers.
This method provides flexibility, but additionally some complexity.
Why Many Folks Select Devoted {Hardware}
Devoted {hardware} stays in style for good purpose. For a lot of householders, it’s the shortest path between:
“I need a sensible house”
and
“I’ve a working sensible house.”
A preinstalled choice like Residence Assistant Inexperienced removes a lot of the work concerned with virtualization or server administration.
Advantages embody:
- Easy setup
- Fewer transferring elements
- Equipment-like habits
- Much less infrastructure to handle
- Decrease studying curve
In case your purpose is:
“I need Residence Assistant to really feel like a thermostat or router”
devoted {hardware} has actual enchantment.
That is very true for those who don’t already run a homelab.
The Residence Assistant crew has achieved a superb job making devoted {hardware} approachable and dependable.
A Raspberry Pi 4 can nonetheless work as nicely, though I are inclined to lean towards the extra appliance-like choices immediately or a small mini-PC in order for you extra headroom.
Should you’re evaluating platforms, I put collectively a information protecting the greatest selections for Residence Assistant {hardware}, together with devoted home equipment and mini-PC choices.
Why Many Energy Customers Want a VM
That is the place my very own choice begins to indicate. I like operating Residence Assistant in a VM. Not as a result of it’s quicker. Not as a result of it’s extra “superior.” Principally as a result of it offers me flexibility and peace of thoughts.
Residence Assistant merely doesn’t want an enormous quantity of computing energy. So dedicating a complete pc to it will possibly typically really feel wasteful, significantly if you have already got virtualization infrastructure accessible.
Operating HAOS in a VM offers you many benefits.
Snapshots and Restoration
That is in all probability the most important one.
Earlier than main upgrades or configuration modifications, you possibly can snapshot the VM.
If one thing breaks:
That’s onerous to overstate.
Residence Assistant’s personal backup system is great—and I exploit it—however VM snapshots add one other layer of safety.
Simpler Migration
Want new {hardware}? VMs make that simpler. As an alternative of rebuilding from scratch, you possibly can typically:
- migrate
- restore
- reattach gadgets
- proceed working
This turns into extra worthwhile as your sensible house grows.
Higher {Hardware} Utilization
Many people already run:
- NAS methods
- Docker containers
- Proxmox hosts
- homelab infrastructure
In that scenario, letting Residence Assistant share current assets is sensible.
One modest server can help:
- Residence Assistant
- MQTT
- containers
- utility companies
- automation instruments
…all with out stressing the {hardware}.
Scaling Later
Residence Assistant itself is light-weight, however some workloads usually are not.
Issues like:
- digicam processing
- AI integrations
- dashboards
- companion companies
can change your necessities over time.
VMs make useful resource changes comparatively painless.
Want extra RAM? Allocate it. Want extra disk? Resize it. That flexibility is sweet.
My Expertise Shifting to HAOS in Proxmox
For years I ran Residence Assistant Core in a Python digital surroundings.
It labored.
However over time, sustaining it grew to become more and more annoying.
Residence Assistant finally started deprecating older set up strategies, and each main replace appeared to contain:
- rebuilding Python environments
- fixing dependencies
- coping with guide upkeep
That grew to become tougher to justify.
I documented the complete course of in my article about migrating Residence Assistant from a Python digital surroundings to HAOS in Proxmox.
The quick model? It was value it.
My older setup required extra guide upkeep and more and more felt like one thing I needed to handle fairly than merely use. HAOS simplified upgrades and made every little thing formally supported.
The migration itself went surprisingly nicely.
I:
- snapshotted the previous VM
- created a brand new HAOS VM
- restored from backup
- reassigned USB gadgets
- labored by just a few hiccups
The most important points concerned:
- Z-Wave rebuilding
- reauthentication of some integrations
- just a few configuration tweaks
However the backups labored remarkably nicely and preserved most of my setup.
Afterward, updates grew to become dramatically simpler. Residence Assistant upgrades now occur from the UI and easily work. Even HAOS updates are built-in into the method. That was a significant enchancment.
And truthfully, this line from my migration article nonetheless summarizes my philosophy fairly nicely:
“The true check can be if anybody in my household notices something. I doubt they’ll—and that’s precisely the way it ought to be.”
Nobody has observed. Dependable house know-how ought to fade into the background.
Reliability and Restoration
Folks typically assume devoted {hardware} is robotically extra dependable. I’m unsure that’s all the time true. Each approaches could be very reliable.
The actual distinction is how they fail and the way you get better.
Devoted {Hardware} Restoration
With devoted {hardware}, restoration usually is dependent upon:
- Residence Assistant backups
- substitute {hardware}
- restore course of
This works nicely as Residence Assistant backups are genuinely glorious.
But when a tool dies unexpectedly, restoration could contain:
- substitute {hardware}
- SD card restoration
- reconfiguration
That isn’t horrible, however it takes time.
VM Restoration
That is the place VMs shine. You continue to use HA backups.
However now you even have:
- VM snapshots
- hypervisor backups
- migration instruments
- {hardware} portability
In case your host {hardware} modifications, restoration is commonly a lot less complicated. For me, snapshots are the most important win. They scale back nervousness round upgrades and experimentation.
Upkeep and Updates
Upkeep is one space the place devoted {hardware} could have a bonus. There’s merely much less infrastructure concerned.
With devoted {hardware}:
- replace Residence Assistant
- replace HAOS
- achieved
That simplicity issues.
With a VM, you will have one other layer: the virtualization host. Meaning:
- Proxmox updates
- host patching
- VM administration
So sure, upkeep could be barely increased.
Alternatively, for those who already keep virtualization infrastructure, this will not really feel like extra work in any respect.
In my case, I already run Proxmox and different companies. Residence Assistant turns into yet another VM fairly than yet another pc to handle.
Efficiency, Price, and Energy
Efficiency often isn’t the deciding issue. Residence Assistant is environment friendly. For most individuals devoted {hardware} or a VM will really feel equally responsive.
The extra significant dialogue is round:
- value
- energy
- useful resource utilization
Devoted {Hardware}
Benefits:
- predictable energy use
- easy sizing
- low idle draw
- purpose-built choices accessible
A Residence Assistant Inexperienced makes use of little or no energy and is straightforward to justify.
VM Strategy
If you have already got a number VM typically wins. As an alternative of:
- shopping for one other pc
- powering one other system
…you reuse current infrastructure.
After all, if you have to construct a Proxmox server solely for Residence Assistant, the equation modifications. At that time, devoted {hardware} in all probability makes extra sense, until you’re planning on different VMs anyway.
Should you’re exploring virtualization hosts, my article protecting Proxmox small type issue {hardware} could assist.
I additionally run Residence Assistant on a Beelink mini-PC platform and have written about my expertise with the Beelink EQi13 Professional.

Select a VM If:
- You already run Proxmox or virtualization
- You’re snug with VMs
- You worth snapshots and restoration
- You need environment friendly {hardware} use
- You take pleasure in flexibility and tinkering
That is the place I land. However I acknowledge it isn’t common.
Last Ideas
There isn’t a single appropriate reply right here. Residence Assistant runs nicely on devoted {hardware} and in digital machines. The higher selection relies upon much less on Residence Assistant itself and extra on:
- your consolation degree
- your infrastructure
- your long-term objectives
My default suggestion is that this: Should you already run virtualization infrastructure or are keen to study it, I feel Residence Assistant in a VM is tough to beat. The pliability, snapshots, and portability are highly effective benefits.
However in order for you the best, lowest-friction expertise doable, devoted {hardware} stays an excellent—and sometimes very sensible—selection.
