Smart light switches
Smart light switches replace the wall switch you already have, so the lights you control by hand also answer to an app, a schedule or your voice. Pick by gang count and wiring.
Gang count
A gang is one switch button on the plate. A single-gang switch controls one circuit, a three-gang controls three. Count the buttons on the switch you are replacing and match it.
Neutral or no-neutral
Most smart switches need a neutral wire for constant power. Many older Australian homes do not run one to the switch, so look for a no-neutral model if yours is missing.
Platform
Wi-Fi switches join your network on their own. Zigbee and Matter switches talk to a hub but hold up better across a larger home.

Filter guide
Which protocol should I pick?
Protocols are the wireless languages smart devices use to talk to each other. Some need a hub, some run straight off your Wi-Fi. Here's what each one means for your setup.
-
Zigbee
Low-power meshThe cleanest mesh for a bigger setup. Every mains-powered device repeats the signal, so coverage grows as you add more. Needs a hub like a Hue Bridge or SmartThings.
-
Wi-Fi
No hub neededThe simplest way to start. Plugs into your existing Wi-Fi with no extra hardware. Best for a handful of devices; very large setups can crowd the network.
-
Bluetooth
Direct, short-rangeGood for setup and close-range control from your phone. Range is short with no remote access on its own, so it's often paired with a hub or bridge.

Choosing a smart light switch
Check for a neutral wire first
Most smart switches need a neutral at the switch, and some are built to work without one. Only an electrician can tell you which you have, since opening a switch is licensed work in every state. If there is no neutral, a no-neutral model or a relay behind the light will both do the job.
Match the gang count to your plate
A gang is one button on the switch. Count the buttons you have now, one for a single light, three for a row that runs the hallway, and buy the same. A multi-gang smart switch keeps every circuit on the one plate, so a busy switch stays one tidy unit rather than a wall of separate controls.
Keep the switch you like
If you would rather not change the look of the wall, a smart relay wires in behind the existing switch and makes it smart while the original plate stays put. Good for heritage plates or a spot where the wiring suits a module better than a new switch.

It replaces your wall switch and adds app, voice and schedule control to the lights already wired to it. You still flick it by hand, but you can also dim or time those lights, or switch them from your phone, without touching the globes themselves.
Swap the existing switch for a smart one wired into the same circuit, which a licensed electrician does in a single visit. If you would rather keep the current plate, a smart relay fits behind it instead. Either way the lights stay where they are.
Yes, if you choose a no-neutral model. Many older Australian homes do not run a neutral to the switch box, and a no-neutral switch is built to power itself without one. Check the listing for "no neutral required" before you buy, or have your electrician confirm what is in the wall.
The main ones are wiring and cost. A mains switch must be installed by an electrician, so there is a fitting fee on top of the switch, and a model needing a neutral wire will not suit every older home. Wi-Fi models also rely on your network staying up to reach the app.
