Smart lighting used to mean buying a separate hub — a small box that plugged into your router and talked to your bulbs. That's no longer necessary. Plenty of today's smart bulbs, plugs and switches connect straight to your Wi-Fi, which means you can automate a room with nothing more than the devices themselves and an app on your phone.
Here's how to do it, and where the limits of a no-hub setup actually are.
Pick the right kind of device
You have three main options, and they suit different situations:
- Wi-Fi smart bulbs screw into your existing fixtures and give you dimming and, on many models, colour. Best when you want per-bulb control or coloured light.
- Wi-Fi smart plugs turn an ordinary lamp into a controllable one. Best for floor and table lamps where you don't need dimming.
- Wi-Fi smart switches replace the wall switch itself and control everything wired to it. Best for ceiling lights and hallways, though they require basic electrical work.
Check the bulb base and shape (for example a standard screw fitting versus a bayonet), the brightness in lumens, and whether you want tunable white or full colour. Matching these to your fixtures saves a return trip.
Get the basics connected
Setup mirrors any other Wi-Fi device: install the maker's app, create an account, put the device into pairing mode, and enter your Wi-Fi details. As with most home gadgets, expect to use the 2.4 GHz band. Name each light clearly — “Bedroom left” beats “Bulb 2” — and group lights by room so you can control several at once.
Build automations in the app
This is where a hub used to earn its keep, and where the companion app now does the job instead. Common no-hub automations include:
- Schedules: lights that come on at 7 a.m. and off at 11 p.m.
- Sunrise and sunset: timings that follow local daylight and shift automatically through the year.
- Countdown timers: a light that switches itself off 20 minutes after you turn it on.
- Scenes: one tap that sets several lights to a preset brightness and colour — “Movie” or “Dinner.”
- Away simulation: lights that cycle on and off while you're out.
Add voice control
You can control no-hub lights by voice without buying a hub, because the assistant already lives on your phone or a speaker you may already own. Link your lighting account to the assistant, and the device names you chose become the commands: “turn off the bedroom lights.” Grouping rooms in the app means one phrase can control several bulbs at once.
Keep the physical switch in mind
Smart bulbs only respond when they have power. If someone flips the wall switch off, the bulb goes dark and drops off the network until the switch is back on. Two ways around this:
- Leave the wall switch on and get the household used to the app or voice instead.
- Or choose a smart switch rather than smart bulbs, so the wall control stays live and everyone can still use it normally.
Where no-hub setups fall short
Skipping the hub is convenient, but it's worth knowing the trade-offs:
- Everything depends on your Wi-Fi. If your router is down, cloud-based automations may not run.
- Many actions round-trip through the cloud, which can add a slight delay compared with a local hub.
- Mixing brands can mean juggling several apps, each with its own account and automations.
The Matter standard is designed to ease that last problem by letting devices from different makers work together in one place, so it's worth looking for on the box if cross-brand control matters to you.
Start small
You don't need to convert the whole house at once. Automate one room — say, a bedside lamp on a schedule and a couple of overhead bulbs on voice control — and live with it for a week. You'll quickly learn which automations you actually use, and you can expand from a setup you already trust. No hub required.
