Home Assistant 101

My guidance for the smoothest setup.

This is a short path, not every option. Home Assistant can run a lot of ways. If you want the fewest dead ends, do it like this.

1. Run Home Assistant OS

Use Home Assistant OS (HAOS) on a dedicated little machine. That gives you the full UI, add-ons, backups, and updates in one place.

Skip Docker, supervised installs, and “I’ll put it on the NAS later” for a first setup. Those work, but they are where people get stuck.

2. Pick boring hardware

Anything that runs HAOS cleanly is fine. In practice:

• Home Assistant Green— simplest buy-and-plug option.
• A small Intel NUC / mini PC— more headroom if you might grow into cameras, voice, or lots of integrations.
• Raspberry Pi— works, but treat storage carefully (SSD over SD card if you can).

Give it a wired Ethernet connection if you can. Wi-Fi is fine for trying it; Ethernet is quieter long-term.

3. Install once, then don’t touch the install

Flash HAOS, boot, open the onboarding URL on your phone or laptop (same network), create your local account, and finish the wizard.

Then leave the OS alone. Almost everything else happens inside Home Assistant: Settings → Devices & Services, dashboards, automations, backups.

4. Add one thing at a time

Start with devices you already have (lights, thermostat, a sensor). Get one integration working and visible on a simple dashboard before you chase the next.

Backups: turn on automatic backups early (Settings → System → Backups). Future you will care.

5. When you’re ready for money on a wall tablet

If you use Lunch Money and want balances in Home Assistant, that’s a separate integration once HA itself is solid: Lunch Money for Home Assistant.
