For most Home Assistant installations, run Home Assistant OS on hardware in your home. Home Assistant’s most important work—controlling LAN devices and USB-connected Zigbee, Z-Wave or Bluetooth radios—depends on local network access. A virtual private server (VPS) is elsewhere on the internet, so it cannot reach those devices directly. Choose a VPS when your installation is mainly cloud-based, or use one as a secure relay for remote access to a Home Assistant instance that remains at home.
The short answer: home server for control, VPS for connectivity
A home server keeps Home Assistant beside the devices it controls. Automations can continue when your internet connection fails, and USB radios can be plugged directly into the host. The trade-off is that you own the hardware, power, storage, backups and local-network troubleshooting.
A VPS gives you a datacenter-hosted Linux machine with a public internet connection. It is convenient for remote administration and can be very useful as a reverse-proxy or VPN endpoint, but it is not physically connected to your home network. Without a tunnel or VPN, it cannot see Zigbee, Z-Wave, Bluetooth or ordinary LAN devices.
The practical pattern for many households is therefore hybrid: run Home Assistant OS (HAOS) at home, keep the radio coordinator near the center of the home, and use an official cloud subscription, a mesh VPN or a small VPS relay for access while away.

Why Home Assistant’s networking model matters
Local integrations expect local reachability
Home Assistant talks directly to devices on your network and to radios attached to its host. A Zigbee or Z-Wave USB coordinator is a local USB device; Bluetooth discovery depends on radio range; many thermostats, lights, media players and appliances are found through multicast or local IP traffic. A VPS in a hosting facility has none of those paths by default.
You can bridge the networks with a site-to-site VPN, an outbound tunnel or a carefully designed application gateway. That adds another system that must be configured, updated and monitored. Exposing a coordinator or a broad set of LAN services to the public internet is an avoidable security risk.

With HAOS at home, automations that only need local devices can continue when the wide-area connection is down. This is particularly important for heating, leak detection, lighting and locks. Cloud-only integrations, remote notifications and voice services may still stop working because their providers are unreachable.
With Home Assistant hosted only on a VPS, your home network becomes dependent on the internet path to that VPS. A local router outage, ISP outage or VPN failure can prevent commands from reaching devices even though the VPS itself is healthy.
Reliability claims need context
Hosting companies commonly describe VPS platforms as more reliable than a residential connection because of datacenter power, redundant links and monitoring. That describes the server’s facility, not the complete path between your home and the VPS. A home installation has the opposite advantage: local automations do not require that path. Decide which failure—datacenter downtime or loss of your home internet connection—would be more damaging to your use case.
Home-server hosting
HAOS is the simplest self-hosted route
Home Assistant’s installation guidance recommends Home Assistant OS for most people installing on their own hardware, including a Raspberry Pi, an Odroid or a 64-bit x86 machine. HAOS bundles the appliance-style operating system, Home Assistant, supervisor functions, updates and add-ons. It is generally easier to maintain and restore than assembling a Linux distribution and container stack yourself.

Home Assistant Green is the official plug-and-play appliance. It removes most hardware-selection and operating-system decisions, but it offers less expansion headroom than a more powerful x86 mini PC. Linux, macOS, Windows and container-only installations are valid alternatives, yet they require you to manage more of the host operating system and do not provide the same add-on workflow.
Hardware requirements and realistic sizing
Published guides differ, so treat the following numbers as practical estimates rather than Home Assistant project guarantees. A commonly cited HAOS minimum is 2 GB of RAM and 32 GB of storage on a 64-bit x86 or ARMv7-or-newer processor. Some older guides still quote 1 GB of RAM and 16 GB of storage; those figures leave little room for add-ons, databases and backups.
A more comfortable starting point is at least 4 GB of RAM and a 64 GB or larger SSD, preferably NVMe where the platform supports it. Storage speed and endurance matter because the recorder database writes continuously; inexpensive microSD cards are a frequent weak point. An SSD also makes recovery and database maintenance less painful.
| Home hardware | Best fit | Advantages | Constraints |
|---|---|---|---|
| Home Assistant Green | First-time users wanting an appliance | Official, preconfigured and low-maintenance | Less expansion capacity than a mini PC; radio hardware may still be external |
| Raspberry Pi 5 with SSD | Low-power DIY installations | Small, efficient and widely supported | Requires an SSD, enclosure, power supply and radio placement planning |
| Odroid-class ARM board | Users comfortable with single-board computers | Compact local host with HAOS support | Accessory and storage choices vary by model |
| x86-64 mini PC | Large installations, cameras or local AI | More CPU, RAM and storage headroom; easier upgrades | Higher purchase price and power use than a small ARM board |
Memory demand rises with add-ons. A rough planning estimate is about 4 GB of RAM for Zigbee2MQTT plus an MQTT broker, and about 8 GB when Frigate is processing two to four cameras. Actual use depends on resolution, retention, hardware acceleration and the rest of your integration set, so monitor memory and swap after deployment rather than treating those figures as fixed requirements.
Radio placement is part of the server design
Zigbee and Z-Wave require a USB coordinator or a built-in radio. Bluetooth range also depends on the host’s location and antenna. Place the coordinator away from USB 3 interference, metal cabinets, Wi-Fi access points and the server’s power brick. A short USB extension cable can improve reception by moving the stick into open air. A VPS cannot provide this physical radio connection.
Installing a home server with Home Assistant OS
The exact imaging screens change over time, but the process is consistent. Use hardware with a supported 64-bit x86 or ARM architecture, reliable power and wired Ethernet where possible.

- Choose and prepare storage. Prefer an SSD over a microSD card. Back up any existing data because writing the HAOS image erases the target drive.
- Download the current HAOS image for your board. Select the image that matches the hardware architecture; do not use an x86 image on an ARM board.
- Write the image to the SSD or boot media. Use a verified imaging utility, safely eject the drive, then install it in the host.
- Connect Ethernet, power and radios. Plug in the Zigbee or Z-Wave coordinator only after the system is positioned where it will operate. Record the USB device path so a later reboot does not lead you to select the wrong adapter.
- Complete first boot. Open the Home Assistant onboarding page from a device on the same LAN, create the administrator account, set the location and time zone, and allow discovery to find local integrations.
- Configure backups before adding complexity. Create a full backup, copy one off the host, and test that you can download it. An automated schedule is more useful than a backup that exists only on the same disk.
- Add radios and integrations incrementally. Pair a few devices, confirm stable links and naming, then continue. This makes it easier to identify whether a problem is caused by placement, firmware or an integration.
Keep the host on a UPS if a brief power interruption could unlock doors, stop heating or corrupt the database. A UPS does not solve an extended outage, but it can provide enough time for a clean shutdown.
VPS hosting
When a VPS is a good fit
- Your devices and automations are predominantly cloud-based and do not require LAN discovery.
- You want a public, stable endpoint for a reverse proxy, VPN coordinator or tunnel.
- You need an always-on Linux environment and are comfortable administering updates, firewalls, SSH keys, backups and monitoring.
- You are building a development or demonstration instance rather than controlling safety-critical equipment at home.
What a VPS cannot do by itself
A VPS does not automatically reach your home subnet, USB radios or Bluetooth devices. Installing Home Assistant in a container on the VPS solves the software location problem, not the network one. You would still need a VPN or tunnel, and the home side would need a device that remains online to carry the traffic.
Recommended Free Tools
Putting a Zigbee coordinator on a USB-over-IP service is technically possible but adds latency, dependency and failure modes. It is generally less robust than keeping the coordinator beside Home Assistant.
VPS administration overhead
Unlike HAOS, a generic VPS usually leaves you responsible for the Linux operating system, container runtime, TLS certificates, firewall rules, intrusion protection, updates and off-site backups. A managed VPS may simplify some of those tasks, but the provider’s reliability does not remove the need to secure your Home Assistant account and tunnel.
| Decision factor | Home server | VPS-only installation |
|---|---|---|
| LAN and radio access | Direct; ideal for Zigbee, Z-Wave, Bluetooth and local IP devices | Unavailable without a VPN or tunnel |
| Operation during home-internet outage | Local automations can continue | Home devices are generally unreachable |
| Remote access endpoint | Requires a secure outbound or inbound path | Public endpoint is available by design |
| Hardware maintenance | You replace disks, power supplies and boards | Provider supplies virtual hardware; you maintain the guest system |
| Security responsibility | Router, host and remote-access configuration | Guest OS, public services, firewall and remote-access configuration |
| Best use | Whole-home automation with local devices | Cloud-heavy setups or a relay for a home instance |
Remote access without exposing Home Assistant directly
Official cloud access
Nabu Casa is Home Assistant’s official paid cloud service and is designed to provide remote access without you opening router ports. One vendor blog has quoted a price of $75 per year, but that figure was not verified against the official pricing page and may change by region or date. Check the current subscription price before budgeting.
Mesh VPN: Tailscale or Headscale
A WireGuard-based mesh VPN can put your phone, laptop and home server on a private overlay network. Tailscale is managed; Headscale is a self-hosted control server that can run on your own VPS. Neither requires ordinary inbound port forwarding, and both let you restrict access to specific devices. You still need to protect the VPN account and keep the client software updated.

VPS as a reverse-proxy relay
This hybrid design leaves Home Assistant at home. The home server makes an outbound VPN or tunnel connection to the VPS; the VPS accepts remote HTTPS connections and forwards them through that private path. Because the home router does not need an inbound port, the attack surface is smaller than direct forwarding.
- Install a minimal, patched Linux system on the VPS and create an administrator account that uses SSH keys rather than password login.
- Build a private tunnel from the home network to the VPS. Configure it to reconnect automatically after either endpoint reboots.
- Run a reverse proxy on the VPS and terminate HTTPS there. Forward only the Home Assistant service through the tunnel.
- Restrict the proxy to the required hostname and port. Do not expose the Home Assistant host’s management interfaces or unrelated LAN services.
- Test access from cellular data, then test failure recovery by restarting the home router, Home Assistant host and VPS separately.
This arrangement is useful when you want a fixed public endpoint but still need local radios and local automations. It does introduce two machines and a tunnel to monitor.
Cloudflare Tunnel or reverse SSH
An outbound Cloudflare Tunnel and a reverse SSH tunnel can avoid router configuration. They are convenient for occasional access, but traffic passes through a third party in the managed-tunnel case, and reverse SSH requires you to manage keys, keepalive settings and reconnection. Apply the same least-privilege rule: publish only Home Assistant, not your entire LAN.

Forwarding a router port directly to Home Assistant is the weakest option in this group. It places a home service on the public internet and makes mistakes in TLS, authentication or software updates more consequential. If you use it despite the risk, require HTTPS, multi-factor authentication where available, strong unique credentials, rapid updates and a firewall policy that exposes nothing else.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Security checklist for either architecture
- Use a unique administrator password and enable multi-factor authentication where supported.
- Keep HAOS, add-ons, containers, VPN clients and the VPS operating system patched.
- Segment untrusted IoT devices from computers and administrative interfaces with separate network zones or VLANs when your router supports them.
- Allow management access only from the LAN or private VPN; do not publish SSH, the hypervisor or router administration to the internet.
- Review add-ons and custom integrations before installing them, and remove anything you no longer use.
- Store encrypted backups off the Home Assistant host. A backup on the same disk does not protect against disk failure, theft or ransomware.
- Revoke old VPN devices, SSH keys and cloud sessions when a phone, laptop or household member loses access.
Choosing between the two: a practical decision framework
Choose a home server when any of these are true
- You use Zigbee, Z-Wave, Bluetooth or devices discovered through local multicast.
- Locks, heating, leak sensors or lighting must continue working during an ISP outage.
- You want the lowest network complexity and are willing to maintain a small computer.
- You prefer one local appliance with HAOS add-ons and a direct USB connection to radios.
Choose VPS-only hosting when all of these are true
- Your integrations are cloud APIs or services that do not need local discovery.
- You accept that a home-internet outage disconnects the automation engine from the home.
- You can administer Linux security, backups and monitoring, or have someone who can.
- The cost and latency of a VPN path to any remaining local service are acceptable.
Choose the hybrid model when your needs are mixed
For most advanced installations, keep the controller and radios at home and use Nabu Casa, a mesh VPN or a VPS relay for remote access. This preserves local operation while giving you a stable way to reach the dashboard away from home. Send backups to a separate location so a failure at home does not remove both the system and its recovery data.
Common problems and fixes
“The VPS cannot find my devices”
Check whether the device is local-only. If it uses Zigbee, Z-Wave, Bluetooth or LAN discovery, the VPS needs a working site-to-site VPN or tunnel. Moving Home Assistant back to the home network is usually simpler than trying to export every protocol to the VPS.

“Remote access stopped after changing routers”
Confirm that the home host received a new address, that the tunnel client started after reboot and that the VPS proxy still points to the tunnel address rather than an old LAN address. Test the service from outside the home Wi-Fi.
“Devices became unreliable after adding a radio”
Move the USB coordinator away from USB 3 ports, access points and metal enclosures. Use an extension cable, check coordinator firmware compatibility and allow time for the mesh to rebuild. Do not place the radio in a basement cabinet simply because the server is there.
“The database is slow or the host is running out of space”
Check recorder retention and large camera histories, then move from an aging microSD card to an SSD. Add RAM if monitoring shows sustained pressure, especially when running Zigbee2MQTT, MQTT, Frigate or several cameras.
“A power cut corrupted the installation”
Restore the latest verified backup to replacement storage, then pair or reconnect any hardware that changed identity. A UPS and scheduled off-site backups reduce the chance that the same event destroys both the running system and its recovery copy.
Bottom line
Run Home Assistant OS at home on a Raspberry Pi 5 with an SSD, Home Assistant Green or an x86-64 mini PC, choosing the latter when you need camera processing or local AI headroom. Keep the host near the Zigbee or Z-Wave coordinator and design for local operation first. For secure access while traveling, use Nabu Casa, a mesh VPN such as Tailscale or Headscale, or a small VPS acting as a reverse-proxy relay. A VPS-only installation is sensible mainly for cloud-based setups; it is not a drop-in substitute for a local Home Assistant controller.
