Almost everyone builds their smart home in the wrong order. They grab a four-pack of cheap bulbs and a random plug because they were on sale, scatter them around the house, and then wonder why nothing automates, why half of it drops offline, and why none of it works when they are not home. The piece they skipped is the one that makes everything else behave: a home hub. Buy that first and the rest of HomeKit clicks into place. Buy it last and you spend months fighting devices that were never going to cooperate without it.

I have run an Apple-centric smart home for years, torn most of it out at least once, and learned the order the hard way. The good news is that a reliable HomeKit setup is genuinely simple now, far simpler than the YouTube battle-stations make it look. You need a hub, a small standard you should care about, and then a deliberately short shopping list bought in the right sequence.

Buy the hub first, always

HomeKit needs a home hub to run automations, give you access when you are away, and act as the brain the rest of the gear reports to. Your options are an Apple TV 4K or a HomePod, and which you pick barely matters as long as you have one. The Apple TV is the one I would start with if you watch anything on the telly anyway, because it is a hub that earns its keep twice; the HomePod mini is the cheaper, smaller route and adds a decent speaker and Siri in whatever room you put it.

There is a quiet bonus here that matters enormously. The HomePod mini, the full HomePod, and the Apple TV 4K all include a Thread border router, and that single fact upgrades your whole network for the better gear you are about to buy. Skip the hub and you are not running a smart home; you are running a few gadgets that happen to have an app. If you already have an Apple TV under the telly, congratulations — you own a home hub and did not know it, and you can skip straight to lights.

The two words worth understanding: Matter and Thread

You do not need to become an engineer, but two terms will save you money. Matter is the cross-industry standard that lets a device work with Apple Home, Google, Amazon, and Samsung at once — buying Matter gear means you are not locked to one ecosystem forever, which is worth a small premium for peace of mind. Thread is a low-power mesh network where each mains-powered device repeats the signal for its neighbours, so the more Thread gear you own, the more solid the whole thing becomes. That is why the hub matters: its border router is the on-ramp to that mesh.

The practical rule: prefer Matter-over-Thread devices where they exist and the price is sane, and do not agonise over the rest. Older HomeKit-only gear still works fine; you are just future-proofing the new stuff.

What to buy, and the order to buy it in

Resist the urge to do the whole house in a weekend. The right sequence gives you a win on day one and avoids the pile of returns that comes from buying everything before you know what you actually use.

Lights come first, because they are the everyday magic. Philips Hue is still the gold standard — the bridge-based system is rock-solid, the bulbs are excellent, and it is the one I would hand a sceptical family member. If you would rather skip a second bridge, Nanoleaf Matter-over-Thread bulbs talk straight to your HomePod hub. Start with the rooms you use at night, the living room and the bedroom, and do not wire up cupboards nobody stands in.

Then a smart plug or two, which is the cheapest way to make a dumb lamp, fan, or coffee machine smart. Eve Energy is a lovely Thread-and-Matter plug that also reports power use; a Meross plug is the budget pick that simply works.

Sensors next, because automations get clever once the house can sense itself. An Eve Motion sensor turns the hallway light on when you walk in; an Eve Door and Window sensor tells you the back door is open; a temperature sensor can nudge a fan. This is the point where the home stops being a set of remote controls and starts doing things on its own.

Locks and cameras last, because they cost the most, demand the most trust, and benefit from a network you have already made solid. A HomeKey-compatible lock like the Aqara U-series or a Level Lock lets you open the door by tapping your iPhone or Apple Watch, which is the kind of small luxury that feels absurd until it is gone. For cameras, anything supporting HomeKit Secure Video — a Logitech Circle View, an Aqara, or an Eve Cam — keeps your footage encrypted in iCloud rather than on some manufacturer’s server, which is the whole reason to stay in Apple’s lane. That feature needs an iCloud+ plan, so factor the small monthly cost in.

The traps worth dodging

A few mistakes show up again and again, and all of them cost money. Wi-Fi-only bulbs from bargain brands work, but a dozen of them hammer your router and drop offline the moment it hiccups — this is the exact problem Thread was invented to solve. Some genuinely lovely Aqara sensors and locks need their own separate hub on top of your Apple one, so read the box and confirm the thing is HomeKit-native or Matter before you hand over money. And cloud-only no-name cameras are the worst of the lot: cheap, yes, but they pipe a live view of your living room to a server you have never heard of, which is the precise opposite of why you chose HomeKit in the first place. The rule that settles most of these: when two devices do the same job, pick the one that speaks Matter or Thread and keeps its data on your own kit.

A sensible starter kit

Here is the shortlist I would actually buy to go from nothing to a real smart home, in order, stopping whenever you have had enough.

What you buy first inside that list depends on what is annoying you most. Sort by your actual gripe:

What I would tell a friend starting today

Buy the hub, then buy lights, then stop and live with it for a fortnight before spending another cent. That single habit — get one layer working, use it, then add the next — is the whole difference between a smart home that delights you and a drawer of abandoned gadgets that quietly judges you. Lean toward Matter and Thread when the price is reasonable so you are not married to one company’s future, keep your cameras on HomeKit Secure Video so your hallway does not end up on someone else’s server, and do not smart-ify rooms you barely use just because the bulbs came in a four-pack. A small HomeKit setup that always works beats a sprawling one that needs a reboot every Sunday — and the people who love their smart homes are, almost without exception, the ones who started with a hub and showed some restraint.
