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.

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.
-
Ethernet
Wired to your routerThe steadiest connection you can give a device. A cable means no Wi-Fi congestion and nothing to drop out, which is why hubs, panels and cameras so often offer it. The catch is physical: it has to sit within cable reach of a network port.
-
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.

How these types differ
The difference is where the dimmer lives, and whether the wiring needs an electrician.
-
Remotes & dials
No wiringBattery-powered, and sticks or sits wherever you want it: on the wall, on a side table, in a drawer. A dial turns brightness up and down; a button remote steps through levels and scenes. No wiring and no electrician, so it's the easiest way in.
-
In-wall modules
ElectricianFits behind your existing switch or in the switchboard, so the wall plate you already have keeps working while the dimming happens out of sight. The tidier retrofit when you don't want to change the look of the switch. Needs an electrician.

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.
