Comparison Guide · Updated June 2026
The two most-discussed Home Assistant hardware platforms. One is plug-and-play, the other is maximally flexible. We'll tell you exactly which one is right for your setup — and which common mistakes to avoid.
Buy the Home Assistant Green if you want to spend your time automating your home rather than configuring hardware. Plug it in, go to homeassistant.local:8123, and you're running in under 2 minutes.
Buy the Raspberry Pi 5 if you want to run Frigate NVR for local camera AI, want maximum performance headroom, or already own a Pi and just need to flash a card.
| Spec / Factor | HA Green | Raspberry Pi 5 (4GB) |
|---|---|---|
| Price (ready to run) | ~$100 | ~$120–160 (Pi + case + SSD + PSU) |
| Setup time | Under 2 minutes. Plug in, done. | 20–30 min. Flash image, configure boot, setup. |
| Processor | RK3566 quad-core Cortex-A55 | BCM2712 quad-core Cortex-A76 (faster) |
| RAM | 2 GB (fixed) | 4 GB or 8 GB |
| Storage | 32 GB eMMC (reliable, no SD failures) | NVMe SSD recommended (SD cards fail over time) |
| Officially supported | Yes — built by Nabu Casa | Community-supported (excellent, not official) |
| Built-in Zigbee/Thread | No — needs USB dongle | No — needs USB dongle |
| Frigate NVR performance | Limited (2 GB RAM, A55 CPU) | Better — handles 2–3 cameras |
| Idle power draw | ~3–5W | ~5–8W |
| Multi-use flexibility | HA only | Run other services alongside HA |
| Long-term reliability risk | eMMC — minimal risk | NVMe = reliable. SD card = fails eventually. |
The Home Assistant Green is purpose-built by Nabu Casa specifically to run Home Assistant OS. Plug in an Ethernet cable and power, and it's running. No SD card to flash, no configuration, no OS selection. The onboarding UI is ready at homeassistant.local:8123 in under 2 minutes.
The eMMC storage is the real advantage over Raspberry Pi builds using SD cards. MicroSD cards fail under the constant read/write load of a 24/7 HA instance — it's when, not if. The Green's eMMC is designed for this workload and doesn't have this problem. For most home automation use cases (under 100 devices, no camera NVR), the 2 GB RAM and Cortex-A55 CPU are completely sufficient.
The Raspberry Pi 5 uses the BCM2712 (Cortex-A76) — meaningfully faster than the Green's Cortex-A55, with better handling of heavy add-ons like Whisper (local speech recognition) and Frigate (local AI camera NVR). The 8GB version can handle 2–3 Frigate camera streams at reasonable resolutions alongside a full Home Assistant instance.
Storage warning: Do not use a microSD card as your primary storage. In 2026, this is mandatory advice. Use a NVMe HAT (Pimoroni or Waveshare make solid options) with an M.2 SSD. It eliminates the SD card reliability problem entirely. Budget $20–30 extra for this — it's not optional for a 24/7 HA install.
Neither the Green nor the Raspberry Pi 5 have a built-in Zigbee radio. Both need a USB Zigbee coordinator. Our recommendation is the same for both: the Sonoff ZBDongle-P-E ($20) or the official Home Assistant Connect ZBT-2 ($30). Always use a USB extension cable to position the dongle away from USB 3.0 interference.
