For a self-built Home Assistant system, consider a Raspberry Pi 4 or Raspberry Pi 5 with at least 2 GB of RAM. You will also need a suitable power supply, Ethernet for installation, and a microSD card; Home Assistant recommends an A2 card with at least 32 GB. If you would rather skip flashing an operating system and assembling parts, Home Assistant Green arrives with Home Assistant installed.
Which Raspberry Pi works with Home Assistant?
Home Assistant’s installation guide offers Home Assistant OS images for Raspberry Pi 4 and Raspberry Pi 5, and lists 2 GB of RAM as the minimum for this route. The best choice depends less on a published performance ranking—Home Assistant does not provide a controlled comparison of these boards for this use—and more on what you already own, your setup preferences, and current model support status.
There is a support-status nuance: the consumer installation guide provides a Pi 5 image choice, while Home Assistant’s developer board table marks Pi 5 support as “yes (beta).” Check both live pages before buying or installing, rather than treating the beta label as either full maturity or a lack of an installation path.

Pi 4, Pi 5, or Home Assistant Green?
Green is not a Raspberry Pi model; it is Home Assistant’s preconfigured hardware option. Use this comparison to choose a setup path based on published details, not assumed speed differences.

| Option | What the official sources establish | Best fit |
|---|---|---|
| Raspberry Pi 4 | Home Assistant OS installation option; at least 2 GB RAM is listed for the Pi OS route. Home Assistant recommends an A2 microSD card of at least 32 GB, plus suitable power and Ethernet for setup. | You already have a suitable Pi 4 or want to build and configure the host yourself. |
| Raspberry Pi 5 | Home Assistant OS installation option; at least 2 GB RAM is listed for the Pi OS route. The developer board table labels Pi 5 support “yes (beta).” | You want the Pi 5 self-build route and are comfortable verifying the live support status. |
| Home Assistant Green | Ships with Home Assistant OS installed. Its product page lists a Rockchip RK3566 quad-core Arm Cortex-A55 processor at 1.8 GHz, 4 GB LPDDR4X RAM, 32 GB eMMC, and Gigabit Ethernet. | You want dedicated hardware and a simpler start without flashing a Pi image. |
Home Assistant does not publish a controlled performance comparison between Green and the Pi models in these sources, so the listed processor and memory specifications do not establish which will run faster. Green’s appeal is preinstallation and reduced assembly; a Pi makes sense when you already have compatible hardware or prefer a bring-your-own-board setup.

What do you need for a Raspberry Pi installation?
Do not budget for the board alone. Home Assistant’s Pi guide calls for a power supply, microSD card, and Ethernet connection for installation. It recommends an A2 microSD card of at least 32 GB. Some mobile chargers may not provide suitable power, and the guide says not to power the Pi from a computer USB port.

How to install Home Assistant OS on a Raspberry Pi
- Download and open Raspberry Pi Imager, then choose Other specific-purpose OS > Home automation > Home Assistant.
- Select the Home Assistant OS image that matches your board, either Pi 4 or Pi 5. Use the live installation page for the current image; versions change.
- Write the image to the microSD card, insert it into the Pi, and connect the board to power and Ethernet. Keep the Pi on the same network as the computer you use for setup.
- After the Pi boots, open
http://homeassistant.local:8123. If local-name resolution does not work on your network, connect using the Pi’s IP address instead.
Follow Home Assistant’s current Raspberry Pi installation instructions for the live image and any updated prompts.

Home Assistant OS is the recommended installation type for most people bringing their own hardware. Container is a separate route for Raspberry Pi 3, 4, or 5 that uses Docker and assumes Linux command-line skills. Do not treat the two options as interchangeable: choose Container only if you are prepared to manage that environment yourself. Home Assistant installation types.

Do you need a Zigbee or Thread adapter?
Not for every Home Assistant setup. Whether an additional radio is useful depends on the protocols your devices use and whether you already have compatible hubs or radios. Home Assistant identifies Connect ZBT-2 as a USB adapter for Zigbee and Thread. Its Green page says Thread support for the adapter is under development; a Thread-based Matter device also needs a Thread border router on the network. Check current compatibility and availability before buying an adapter. Home Assistant hardware options; Green and adapter details.

How to make the choice
- Choose a Pi 4 if you already own a suitable board and are comfortable preparing a microSD card and installing the operating system.
- Consider a Pi 5 for a self-built system if its current support status suits your needs; Home Assistant’s developer table currently identifies it as beta.
- Choose Green if you prefer Home Assistant preinstalled and want to avoid the Pi imaging process.
- Plan for a radio adapter only when needed. Check your devices’ protocols and existing hubs before adding Zigbee or Thread hardware.
