Which hardware for Home Assistant

Answer five questions (how many devices and cameras, Frigate, a voice assistant) and see which server to run Home Assistant on: Home Assistant Green, Raspberry Pi 5, an N100 mini PC or something bigger.

Home Assistant Green

The official box: plug in and go, HA OS preinstalled, quiet and low power. Plenty for automations, Zigbee and a hundred devices.

AliExpress

Raspberry Pi 5 (8 GB) + NVMe SSD

For tinkerers who want GPIO and HATs. Boot from an SSD (an NVMe HAT), not a microSD card: cards wear out.

AliExpress

Mini PC with Intel N100, 16 GB

The sweet spot: Frigate with OpenVINO for several cameras, local voice (Whisper, Piper), Proxmox with a few VMs, all at ~10 W.

AliExpress

Mini PC with N305 / Core i5 / Ryzen, 32 GB

For many cameras with recording, heavier voice models and several VMs. Add a Coral for Frigate if you go beyond 8–10 cameras.

AliExpress

An old laptop or PC you already have

Costs nothing and has a built-in battery (laptop). Install HA OS on it; just check the power draw: an old desktop can use 40–60 W around the clock.

Links open a search in the shop; some are affiliate links: buying through them costs you nothing extra and supports this site. We do not sell devices or get them from manufacturers.
