Smart dimmer switches
Wall dimmers that set brightness by app, voice or the switch itself, and hold a scene once you have it right. The catch is compatibility, so check the dimming type and your lights before you buy.
Trailing vs leading edge
Leading edge suits older halogen and incandescent loads; trailing edge is the smoother, quieter choice for modern LEDs. Most smart dimmers here are trailing edge, and many auto-detect the load.
Minimum and maximum load
Every dimmer lists a wattage range. Drop below the minimum, common with one or two LED globes, and lights can flicker or refuse to turn off fully.
Control and protocols
Dim over Wi-Fi, Zigbee or Matter, by app, voice or the physical paddle. Matter and Zigbee run locally through a hub; Wi-Fi models connect direct.
Wiring
A dimmer replaces the existing mech in the wall plate. Wiring, including whether a neutral is needed, sits with our light switches.

Choosing a smart dimmer
Match the dimmer to your lights
Trailing edge is the safe default for LEDs: smoother dimming, less hum. Leading edge suits older halogen or incandescent loads. If you are running dimmable LED globes, check the brand against the dimmer, since not every combination dims to the bottom without flicker.
Mind the minimum load
Smart dimmers list a wattage range, and LEDs draw very little. One or two globes can fall under the minimum, which shows up as flicker or lights that will not switch fully off. Add globes, fit a higher-rated load, or pick a dimmer rated low enough for your circuit.
Keep your existing switch plate
Like the look of your current dimmer and just want app and voice control? An in-wall relay or dimmer module fits behind the existing mech instead of replacing the whole switch. It is the tidier retrofit when you are not changing the wall plate.

Some do and some do not. Many smart dimmers run on the active and switched-live without a neutral, which suits older Australian wall boxes, while a few need one. The product spec says which, and our light switches cover how to check what is behind your plate.
Usually, if the globes are marked dimmable and the dimmer is trailing edge. Non-dimmable LEDs will buzz or flicker, and even dimmable ones vary in how low they go. Check the globe is dimmable first, then match it to a trailing-edge dimmer.
The switch on the wall always works by hand, so the lights dim whether or not the internet is up. Matter and Zigbee dimmers also keep app and automation control locally through a hub. Wi-Fi only models lose app and voice control while the connection is down.
Yes. You can save a brightness level as a scene and recall it by app, voice or a tap, and many dimmers fade up to it rather than snapping on. Some also remember the last level you used, so a single press returns to it.
A smart switch is a wall switch, relay or plug you can control from an app, a voice assistant or an automation, instead of only by hand. It replaces or sits behind your existing fitting and works over Matter, Zigbee or Wi-Fi, depending on the model.
Most do, and most Australian homes wired to AS/NZS 3000 have a neutral at the switch. If yours does not, choose a no-neutral model or a relay that sits at the light fitting. Check before you buy: pull the switch plate and look for a bundle of black or blue wires.
For anything wired into the mains, yes. In Australia, hardwired switch, dimmer and relay work must be done by a licensed electrician. Plug-in options are the exception: smart plugs and most wall remotes need no wiring, so you can set them up yourself in minutes.
Pick by the job. Want to set brightness? A dimmer. Replacing a wall switch outright? A light switch. Keeping your existing switch and adding control behind it? A relay. Controlling a plugged-in appliance? A smart plug. Want a battery button with no wiring? A wall remote.
