Somewhere along the way, light switches acquired monthly fees. It's optional. Here's the architecture of a $0/month smart home.
The trick: own the brain
Cloud smart homes rent you the logic. A Home Assistant box owns it instead — automations run on hardware in your cupboard. There is nobody to pay monthly because there is nobody else involved.
What about remote access?
The one thing clouds genuinely provide. Options: Home Assistant cloud ($9/mo, optional, also funds the open-source project) or free self-hosted tunnels (WireGuard/Tailscale) if you'd rather not pay anyone. Either way, your automations never depend on it.
What about cameras?
The subscription industry's favourite product. Local recording via Frigate on your own storage does detection-grade AI with zero cloud — our no-cloud camera guide covers it.
The maths
Ring + Nest + ecosystem subscriptions run $20–50/month forever. A local stack costs hardware once. Eighteen months in, the local house is ahead — and it still works when their servers don't.
Skip the shopping list: the Local Starter Kit bundles the tested gear from this guide — cheaper than buying the parts separately.
