## Choose your Home Assistant host

For a dedicated Home Assistant machine, start with the configured S13. Pay for the EQ14 or a larger host only when your setup needs what they add.

- **[Beelink Mini S13](https://homelabpicks.com/go/beelink-mini-s13)**: A dedicated controller. For a dedicated controller with RAM, storage, and dual 2.5GbE included. Constraint: 16GB DDR4, dual 2.5GbE. Title/bullets say 500GB SATA; selector says 512GB. Confirm capacity. NVMe expansion is PCIe 3.0 x1.
- **[Beelink EQ14](https://homelabpicks.com/go/beelink-eq14)**: NVMe expansion and two displays. For two M.2 2280 PCIe 3.0 slots, two HDMI ports, and a built-in power supply, for about $20 more than the S13. Constraint: Select dual 2.5GbE; other versions have 1GbE. Amazon says NVMe; the maker says SATA. Confirm the included SSD.
- **[A larger virtualization host](https://homelabpicks.com/mini-pc/best-mini-pc-home-server/)**: Several demanding services. For multiple VMs, cameras, or services with greater memory and compute needs. Constraint: Allow for growth before buying an entry-level N-series system.

## Products

### Our Pick: [Beelink Mini S13 N150](https://homelabpicks.com/go/beelink-mini-s13)

Cons:
- The model name alone does not identify Ethernet speed
- Amazon and manufacturer descriptions disagree about the included SSD

## Comparison

| Product | Best fit | Processor | Memory to select | Storage to check | Wired network | Display and power |
| --- | --- | --- | --- | --- | --- | --- |
| [Beelink Mini S13 N150](https://homelabpicks.com/go/beelink-mini-s13) | Dedicated controller | N150 | 16 GB DDR4 | 500 GB SATA SSD; NVMe slot at PCIe 3.0 x1 | 2x 2.5GbE | HDMI; external power adapter |
| [Beelink EQ14 N150](https://homelabpicks.com/go/beelink-eq14) | NVMe expansion, two displays | N150 | 16 GB DDR4 | 500 GB SSD; two M.2 2280 PCIe 3.0 slots | 2x 2.5GbE in reviewed offer | 2x HDMI; built-in power supply |

The best mini PC for Home Assistant is the one that matches how you will maintain it. Our default is a configured **Beelink Mini S13** for a dedicated controller. The **EQ14** is the step up when you want two M.2 NVMe slots, two HDMI ports, or a built-in power supply; the **G3 Plus** is an alternative for one 2.5GbE connection, subject to availability.

We reviewed the product documentation and the actual buying destinations in September 2026. The S13 and EQ14 links identify the configurations described here. The former G3 Plus Amazon destinations display different processors, so we no longer link that model. These are purchasing checks, not lab reliability measurements.

## Choose the installation before the hardware

[Home Assistant recommends Home Assistant OS for most users](https://www.home-assistant.io/installation/). Our buying advice is to choose the simplest installation you are comfortable maintaining:

| Your situation | Installation to consider | What to budget for |
|---|---|---|
| You want a dedicated controller | Home Assistant OS on the mini PC | The configured computer, Ethernet, and any required radios |
| You already maintain a virtualization host | Home Assistant OS in a VM | Memory for the host and guests, USB passthrough, and a recovery plan |
| You already manage Linux and Docker | Home Assistant Container | Host updates and separately managed companion services |

Container installations do not include Home Assistant's managed apps. Do not choose Docker merely because a guide promises that every extra service will be simpler there.

For a new x86 installation, follow the [official generic x86-64 guide](https://www.home-assistant.io/installation/generic-x86-64/), including its UEFI and Secure Boot requirements. Writing the OS image to the boot drive replaces that drive's contents. Decide whether the computer will be dedicated to Home Assistant before installing it.

## Our starting point: Beelink Mini S13

The [S13 buying link](https://homelabpicks.com/go/beelink-mini-s13) is for the N150 model with 16 GB DDR4 on one SO-DIMM and a 500 GB M.2 SATA SSD. **Do not order it expecting an included NVMe drive.** Its second M.2 slot takes an NVMe SSD, but at PCIe 3.0 x1. For a controller, our priority is an appropriate complete system rather than a particular SSD label.

It also has two 2.5GbE ports, Wi-Fi 6, and Bluetooth 5.2, and it uses an external power adapter. One wired connection is enough for a dedicated controller, so the second port stays spare unless you plan a virtualization or network setup. Beelink's own store doesn't list the S13, so these specifications come from the Amazon listing.

If you already run Home Assistant on an N100 machine such as Beelink's earlier Mini S12 Pro, keep it unless a specific limitation is causing trouble. The [S12 Pro](https://homelabpicks.com/go/beelink-n100) is still sold on Amazon, with an N100, 16 GB, a 500 GB SSD, and one gigabit port, which is enough for a dedicated controller. On October 22, 2026, Amazon listed it at $359, $10 more than the S13, so buy it new only if its price falls below the S13's.

## When the EQ14 is worth about $20 more

The [reviewed EQ14 offer](https://homelabpicks.com/go/beelink-eq14) specifies N150, 16 GB DDR4, a 500 GB SSD, and **dual 2.5GbE**. [Beelink also documents dual-gigabit versions](https://www.bee-link.com/products/beelink-eq14-n150), so check the variant selector before ordering.

For about $20 more than the S13, it has two M.2 2280 PCIe 3.0 slots for NVMe drives, two HDMI ports, and a built-in power supply. The replacement Amazon offer says NVMe, while Beelink says SATA III. Confirm the installed drive with the seller. Both machines have dual 2.5GbE, so extra ports are not the reason to choose it.

For Home Assistant by itself, a second Ethernet port is usually unnecessary on either machine. Consider it for a planned virtualization or network setup where you can explain what connects to each interface. Two Ethernet ports do not automatically turn Home Assistant into a router or isolate smart-home devices. Segmentation requires an intentional network and firewall configuration.

If your plans outgrow 16 GB of memory, compare the [larger home-server options](https://homelabpicks.com/mini-pc/best-mini-pc-home-server/) before spending more. Extra ports and drive slots do not compensate for insufficient memory or compute capacity.

## Also consider: GMKtec G3 Plus

The GMKtec G3 Plus is an N150 option with a single 2.5GbE port. Its official configuration information is useful for comparing installed memory and storage. It is not interchangeable with G3 Pro or G11 offers returned by a retailer search.

We don't link it because we couldn't verify a retail listing for this exact model: searches return other GMKtec machines (G3S, G3 Pro, G10, G11) with different processors, and GMKtec's own store showed the N150 G3 Plus sold out. If you find one, confirm the listing names the N150 G3 Plus. Otherwise, compare the verified alternatives above rather than buying a different processor under an old listing. A faster network port is worth paying for only when the rest of your network can use it.

## If fan noise is the deciding factor

The **ASUS ExpertCenter PN42** is a fanless alternative. [ASUS specifies DDR4-3200 memory, not DDR5](https://press.asus.com/news/press-releases/asus-announces-expertcenter-pn42); its port and preinstalled-component options vary. For a barebones offer, include RAM and an SSD in the total cost. Confirm the exact N100/N200 model and whether the optional second LAN port is fitted.

The Amazon PN42 offer we checked was unavailable on September 5, so it is not our default purchase recommendation. Use the manufacturer's configuration information when comparing another seller. We do not assign a universal noise or temperature result to the actively cooled PCs above.

## Buy the radio setup you actually need

Start with your devices. Zigbee, Z-Wave, Thread, and Bluetooth are different requirements; a mini PC's Bluetooth support does not supply all of them.

For Zigbee, use the [ZHA compatibility and interference guidance](https://www.home-assistant.io/integrations/zha/). Place a supported coordinator on a shielded extension cable, away from the computer and other interference sources. Prefer USB 2.0; Home Assistant recommends a powered USB 2.0 hub when the computer only offers USB 3.x ports. A faster USB controller is not a substitute for sensible radio placement.

With a VM, verify that the radio remains assigned to the intended guest after a restart. Before replacing an existing controller, make a backup and check the migration procedure for your integration.

## A useful parts list, without unnecessary rack gear

| Item | When to include it | Buying decision |
|---|---|---|
| RAM and an internal SSD | Always | Confirm they are included in the selected offer; a barebones price is incomplete |
| Ethernet cable | For the wired installation | Check the path to your router or switch |
| A supported radio and USB extension | When your devices require them | Choose from the integration's supported hardware and plan placement |
| Power protection | When outages interrupt important automations | Use our [UPS sizing and buying guide](https://homelabpicks.com/ups-power/best-ups-home-lab/) for the combined load |
| Backup storage outside this computer | For recovery from a drive or host failure | Choose a location you can restore from and test the procedure |

A rack, 10GbE switch, and new NAS are not prerequisites for a dedicated Home Assistant machine. Add infrastructure when it solves an identified problem.

## Decide what would justify a larger host

For a new purchase, we would usually compare configured 8–16 GB machines, leaning toward 16 GB when the price difference is small. That is our planning recommendation, not a promise about how many apps or cameras will fit.

Camera analysis, multiple VMs, and other CPU-intensive jobs need their own resource estimates. If those are central to the project, start with the [home-server guide](https://homelabpicks.com/mini-pc/best-mini-pc-home-server/). If you are comparing small x86 hosts for several lighter services, use the [N100/N150 guide](https://homelabpicks.com/mini-pc/best-n100-n150-mini-pc/).

Do not replace a working Pi or Home Assistant Green simply because this is a mini PC guide. The useful upgrade is the one that removes a limitation you can name.

## FAQ

### How much RAM should I buy for Home Assistant?

For a new mini PC, our practical starting point is 8–16 GB, with 16 GB useful when the configured price is close. This is a buying recommendation, not a minimum requirement. Camera processing, extra apps, and virtual machines need a workload-specific memory budget.

### Should I install Home Assistant OS or use Docker?

Home Assistant OS is the recommended installation type for most users and includes managed apps. Home Assistant Container suits an existing Linux/Docker setup, but you manage the host and companion services yourself. Running Home Assistant OS in a VM is another option when you already maintain a virtualization host.

### Does a Home Assistant mini PC need two Ethernet ports?

A dedicated controller normally needs one connection to your network. Both Beelink picks here have two 2.5GbE ports, but the second matters only for a defined network or virtualization design. Adding a second port does not automatically isolate IoT devices or replace router and firewall configuration.

### Can I plug a Zigbee adapter directly into USB 3?

Home Assistant recommends separating the coordinator from interference with a shielded USB extension cable and preferring USB 2.0. If the computer only has USB 3.x ports, its ZHA guidance recommends a powered USB 2.0 hub. Check the supported coordinator list before buying.

### Is a Raspberry Pi or Home Assistant Green still a sensible choice?

Yes. Keep a working system if it meets your needs. Home Assistant lists both Green and Raspberry Pi installation paths. A mini PC is useful when you specifically want an x86 host, internal storage, or capacity for other services.
