1. Home Assistant Yellow

What It Is

The Home Assistant Yellow is a purpose-built board designed by the Home Assistant team. It ships with a pre-flashed Home Assistant OS, an integrated Silicon Labs EFR32MG21 radio for Zigbee and Thread, an M.2 NVMe slot for fast local storage, and a Gigabit Ethernet port. The 2025 revision pairs with the Raspberry Pi Compute Module 5 (CM5), bringing it in line with Pi 5 performance.

Hardware Requirements

  • Home Assistant Yellow board (with or without CM5 included)
  • 8GB CM5 recommended for future-proofing
  • M.2 NVMe SSD (128GB minimum, 256GB recommended)
  • USB-C power supply (15W minimum)
  • Ethernet cable (Wi-Fi supported but not recommended for a hub)

Step-by-Step Setup

  1. Unbox and install the CM5 if it didn’t ship pre-installed. The CM5 snaps into the SODIMM-style connector on the Yellow board.
  2. Insert your NVMe SSD into the M.2 slot and secure it with the included standoff and screw.
  3. Connect Ethernet and plug in the USB-C power supply.
  4. The Yellow boots directly into Home Assistant OS. Navigate to http://homeassistant.local:8123 from any browser on the same network.
  5. Follow the on-screen onboarding wizard: create your account, set your location/timezone, and opt into or skip analytics.
  6. The Zigbee/Thread radio is auto-detected. Go to Settings → Devices & Services and confirm the ZHA integration was automatically configured.

Configuration Tips

  • Enable the NVMe early. If you initially set up on eMMC, migrate to the NVMe SSD immediately via Settings → System → Storage → Move data disk for dramatically faster database writes and backups.
  • Use the built-in radio wisely. The EFR32 chip handles both Zigbee and Thread, but only one protocol at a time per radio. If you plan to run both, consider adding a second USB Zigbee coordinator (like the SONOFF ZBDongle-E) for Zigbee while dedicating the onboard radio to Thread/Matter. According to the Home Assistant SkyConnect documentation, multi-PAN firmware can bridge both protocols but comes with stability trade-offs.
  • Set up automated backups to a network share or cloud integration. The Yellow makes this easy under Settings → System → Backups.

Troubleshooting

  • Yellow won’t boot? Reseat the CM5 module. The connector can feel secure without being fully inserted.
  • Zigbee devices won’t pair? Ensure the antenna wire (if external) is connected. Check that no other Zigbee coordinator software (like Zigbee2MQTT) is competing with ZHA.
  • Slow performance after migration: Reboot after moving the data disk. If lag persists, check if add-ons like Frigate or Whisper are consuming too much RAM on a 4GB CM5.

2. Raspberry Pi 5

What It Is

The Raspberry Pi 5, released in late 2023, remains the most popular DIY platform for Home Assistant in 2026. Its quad-core Cortex-A76 CPU at 2.4 GHz and up to 8GB of LPDDR4X RAM represent a significant leap over the Pi 4, with Home Assistant reporting up to 2–3× faster dashboard rendering and automation execution (Source: Home Assistant 2024.1 Release Notes).

Hardware Requirements

  • Raspberry Pi 5 (4GB or 8GB)
  • Quality microSD card (A2 rated, 64GB+) or NVMe HAT + NVMe SSD
  • Official Raspberry Pi 27W USB-C power supply (critical — third-party supplies cause undervoltage)
  • Zigbee/Thread USB dongle (SONOFF ZBDongle-E, Nabucasa SkyConnect, or SLZB-06)
  • Case with active or passive cooling (the Pi 5 throttles without a heatsink under load)
  • Ethernet cable

Step-by-Step Setup

  1. Flash Home Assistant OS to your microSD or NVMe SSD using the Raspberry Pi Imager. Select the Home Assistant OS image for Pi 5 from the official download page.
  2. Assemble your hardware: insert the SD/SSD, attach the heatsink or active cooler, plug in Ethernet and the USB Zigbee/Thread dongle.
  3. Power on and wait 5–15 minutes for the initial boot and OS download.
  4. Navigate to http://homeassistant.local:8123 and complete the onboarding wizard.
  5. Set up your Zigbee integration. Go to Settings → Devices & Services → Add Integration → Zigbee Home Automation (ZHA) and select your USB dongle from the detected serial devices.

Configuration Tips

  • Ditch microSD for NVMe. The Pi 5’s PCIe 2.0 x1 interface supports NVMe HATs, and the speed difference for database operations, backups, and add-on performance is transformative. The Geekworm X1001 or Pineberry Pi HatDrive are popular choices.
  • Enable ZRAM to get more effective memory from your 8GB model. This compresses in-memory data and reduces swap usage to the slow SD/SSD.
  • Don’t underestimate cooling. A Pi 5 without a heatsink will thermal-throttle to 1.5 GHz within minutes of sustained load. The official Active Cooler is cheap insurance.
  • Power matters. Undervoltage is the #1 cause of SD card corruption and mysterious crashes on the Pi 5. Use the official 27W supply or a supply that delivers a clean 5.1V/5A.

Troubleshooting

  • “Under-voltage detected” in logs: Replace your power supply immediately. This is the single biggest reliability killer.
  • SD card corruption / read-only filesystem: This is almost always caused by improper shutdown or undervoltage. Switch to NVMe SSD for much better reliability.
  • Zigbee dongle not detected: Some USB 3.0 ports interfere with 2.4 GHz Zigbee signals. Use a short USB extension cable (0.5–1m) to move the dongle away from the Pi.
  • Pi won’t boot with NVMe: Update the Pi 5 EEPROM bootloader to the latest version using rpi-eeprom-update from a Raspberry Pi OS installation.

3. Intel N100 Mini PC

What It Is

The Intel N100 has quietly become the darling of the Home Assistant power-user community. These ultra-compact mini PCs — sold by brands like Beelink, MinisForum, and GMKtec — pack a 4-core Alder Lake-N processor with surprisingly capable single-threaded performance, full-size NVMe/SATA storage options, 8–16GB of RAM, and fanless or near-silent cooling designs. Prices have dropped to $120–$200 in 2026, making them competitive with a fully-equipped Pi 5.

Hardware Requirements

  • Intel N100 mini PC (Beelink Mini S12, MinisForum UN100, or similar)
  • 8GB RAM minimum (16GB recommended if running Frigate, Whisper, or other heavy add-ons)
  • NVMe or SATA SSD (128GB minimum; 256GB+ recommended)
  • USB Zigbee/Thread dongle
  • Ethernet cable (most N100 boxes have dual GbE — a major advantage)

Step-by-Step Setup

  1. Prepare a bootable USB drive with the Home Assistant OS x86-64 image. Use balenaEtcher or dd on Linux to write the haos_generic-x86-64.img.gz file to a USB stick.
  2. Boot the N100 from USB. Enter the BIOS (usually by pressing F2 or DEL at startup), disable Secure Boot, and set the USB drive as the first boot device.
  3. Install to internal storage. The HA OS installer will present an option to install directly to the internal NVMe/SSD. Confirm and let it complete.
  4. Remove the USB drive, reboot, and the N100 will boot into Home Assistant OS from its internal drive.
  5. Navigate to http://homeassistant.local:8123 on another device and complete the onboarding wizard.
  6. Attach your Zigbee/Thread USB dongle and configure ZHA or Zigbee2MQTT as above.

Configuration Tips

  • Use the extra RAM. With 16GB, you can comfortably run Frigate NVR with a Google Coral TPU, Whisper for voice Assist, Mosquitto MQTT broker, and Node-RED simultaneously — workloads that would choke a Pi 5.
  • Leverage dual Ethernet. Many N100 boxes have two GbE ports. Dedicate one to your primary LAN and use the second for an isolated IoT VLAN. Configure this in Settings → System → Network.
  • Enable the Coral TPU. If you’re running Frigate, the N100’s USB 3.0 ports provide reliable bandwidth for a Coral USB Accelerator. The N100’s CPU also supports AVX2, which accelerates software object detection as a fallback.
  • Tame idle power. The N100 idles at around 8–10W, only slightly more than a Pi 5. Configure Linux power management by adding intel_idle.max_cstate=1 to the kernel boot parameters if you experience USB instability at deeper C-states.

Troubleshooting

  • No display output on boot: Some N100 mini PCs have HDMI 2.0 quirks. Try a different HDMI port or cable. The OS will run headless after initial setup anyway.
  • USB Zigbee dongle disconnects randomly: This is a known issue with Intel’s USB power management. In the BIOS, disable USB selective suspend, or add usbcore.autosuspend=-1 to the boot parameters.
  • Wi-Fi card not detected: You don’t need it — use Ethernet. But if the system hangs probing for missing firmware, blacklist the Wi-Fi module in /etc/modprobe.d/.
  • System won’t boot after BIOS update: Some BIOS updates reset the boot order. Re-enter BIOS and set “HAOS” or the internal drive as the first boot option.

Which Should You Choose in 2026?

Scenario Recommendation
You want the simplest, most supported experience Home Assistant Yellow
