Smart lighting for beginners

Buying the whole house at once. Twelve bulbs arrive, the app work takes an evening, the schedules never get written, and three months later somebody has flipped every switch off. Start with one room. The second room takes twenty minutes once you know what you want.

Buying bulbs where a plug would do. If a lamp has one bulb and you like that bulb, a smart plug is cheaper, keeps the light quality you chose, and cannot be undone by the lamp's own switch being left off. Smart bulbs earn their price in fixtures with several sockets, and where you want color or tunable white.

Ignoring the wall switch. A smart bulb needs power to stay on the network. Every time someone turns the switch off, the bulb vanishes from the app. This is the single most common reason smart lighting gets abandoned, and it has to be solved on day one, not after the third argument about it.

1. Works without a hub. A bridge is a reasonable purchase at ten lights and a waste at two.
2. Works with what you already own. Whichever voice assistant is already in the house should be on the box. Matter support means it will still work if you change your mind later.
3. Reversible. A plug and a bulb both come out in seconds. Nothing in a first setup should involve a screwdriver or your landlord.
4. One app if possible. Two brands means two apps means nobody else in the house uses either. Voice or a Matter controller papers over this, but one system per room is the simple version.

Kasa Matter Smart Plug EP25 - buy this first. It makes an existing lamp smart without changing the bulb, speaks Matter so it works with Apple Home, Alexa and Google, and costs less than a smart bulb. A week with one of these tells you whether you want more.
Cons: it switches, it does not dim - dimming stays with the bulb; and it only helps things that plug in.

WiZ Connected Color A19 - the first bulb. Hub-free color and tunable white at the lowest sensible price, from Signify, the company that owns Hue. Put it where you want the color, not where you read.
Cons: neither lumens nor CRI published; Wi-Fi only, so schedules stop when the router does.

Philips Hue White and Color Ambiance A19 - if you already know you will expand. 1,100 published lumens and dimming to 0.2%. Buying into Hue early is cheaper than replacing a house of cheap bulbs later, provided you are honest that you will get there.
Cons: the most expensive route per socket; the Bridge is an extra purchase, and without it you are limited to 10 lights in Bluetooth range.

Lutron Aurora - the fix for the problem that ends most setups. It fits over a standard toggle, holds it on so the bulbs keep power, and dims Hue bulbs by rotating. For a household where other people use the switches, this is not optional.
Cons: it is for Hue bulbs specifically; it covers the switch, which some people dislike the look of; and it is a control, not a light.

Day one: one lamp. Plug, app, done. Name it something a human would say out loud - "living room lamp", not "LR1". Voice control fails mostly on names.

Day two: one schedule. On at sunset, off at bedtime. This is the feature people actually keep using, well ahead of color - schedules and automations has the patterns worth copying.

Day three: solve the switch. Before you add bulbs, not after.

Then stop for a fortnight. If you are still using it, expand a room at a time. If you are not, you have spent the price of a smart plug finding out, which is the cheapest lesson in this hobby.
