Shelly Smart Lighting & Control, Adelaide

Small smart modules that go behind the switch

Shelly makes small relays and dimmers that fit behind an ordinary light switch, or on a DIN rail in the switchboard. Your switch keeps working exactly as it did. On top of that you get control from your phone, timers, sunset schedules and automations, all in the free Shelly Smart Control app. Because the modules are wired into 230 V, they have to be installed by a licensed electrician.

I completed Shelly's installer certification (Bronze) in October 2026, and I am listed on Shelly's installer map. That means I set these up the way Shelly intends, and when the job is done the system is yours, in your own account.

What people use it for

• Garden and outdoor lights On at sunset, off at a set time, and you can check from bed whether you left them on.
• Dimming A Shelly dimmer behind the switch, with the dimming range calibrated to your fittings so there is no flicker at the bottom end.
• LED strip lighting An RGBW controller for coloured or tunable strips, or a dimmer on the driver for plain white ones.
• Lights that follow each other Front and back facade lights that switch together, with no new cable between them.
• Motion lighting A hallway or path light that comes on only when someone walks past and it is actually dark.
• Wireless buttons An extra switch on a wall with no cable run, for a rental or a finished room you do not want to cut into.

The things I check before anything is ordered

• Is the driver dimmable? A Shelly dimmer controls the mains side. LED lights on a non-dimmable driver will not dim properly, so I read the driver label first.
• Is there a neutral at the switch? Some models need one, some do not. Very small loads on a no-neutral dimmer can need a bypass. I pick the model to suit what is in the wall.
• Does your Wi-Fi reach? Shelly Wi-Fi devices use 2.4 GHz. A switch or garden light at the edge of your signal is the most common reason smart control feels unreliable, so I tell you before the job, not after.
• Room behind the switch. The module has to fit in the wall box with the existing wiring, safely and without crushing cables.

How the set-up and hand-over works

• The devices go into your own Shelly account, not mine. You own it.
• I name each device, put it in the right room, update the firmware and calibrate any dimmers.
• Schedules and automations set up with you, so they do what you actually want.
• I show you on your phone how to switch, dim and change a schedule before I leave.
• If you want me to be able to help later, you can share access with my installer code. You can remove it whenever you like.

Frequently Asked Questions

Do I need an electrician to install a Shelly?

Yes, for anything that connects to 230 V. The relays and dimmers sit behind a light switch or in the switchboard and are wired into fixed wiring, which in South Australia is licensed electrical work. Battery buttons, sensors and plug-in devices you can set up yourself.

Will a Shelly dimmer work with my LED lights?

Only if the lights, or the driver feeding them, are dimmable on the mains side. A Shelly Dimmer controls the 230 V supply, so a non-dimmable driver will flicker or do nothing. I check the driver label before anything is ordered, and run the dimmer calibration once it is in.

Who owns the Shelly account?

You do. The devices are set up in your own Shelly account. If you want me to be able to help later, you can give me access with my installer code, and you can take that access away at any time.

Does it need Wi-Fi?

Wi-Fi Shelly devices join your home network on 2.4 GHz. If the switch or the garden lights are at the edge of your Wi-Fi, I will tell you before the job, because a device with a weak signal is the most common reason smart control feels unreliable.

Can I still use the normal light switch?

Yes. The existing switch stays and still works. The Shelly sits behind it and adds phone control, schedules and automations on top.
