Most smart lighting guides assume you are building from scratch. Most people are not. They live in a house with ordinary switches and want lights they can dim, group into scenes and control from their phone, without opening up the walls.
That is what a Pixie smart switch is for. SAL’s Pixie range replaces the switches and dimmers you already have with ones that talk to each other and to your phone. This guide explains how Pixie works, where it makes sense in a smart home, and where it does not.
How Pixie works
- It replaces your existing switch mechanisms. Pixie dimmers and switches go in where the current ones are, using the existing wiring.
- The devices form a Bluetooth mesh. Each one talks to its neighbours, so the system covers the house without a separate control cable.
- You set it up from an app. Rooms, scenes and schedules are created in the app.
- A gateway is optional. Control inside the house works without one. The Pixie gateway adds control away from home and voice assistants.
Because each switch replaces the one already in the wall, a Pixie smart home can be done a room at a time.
Pixie smart switch or Pixie dimmer?
A Pixie smart switch turns a circuit on and off. A Pixie dimmer also sets the level, so it goes on lights that can dim.
As a rule of thumb, loads that cannot dim, such as exhaust fans, go on a switch, and dimmable LED downlights go on a dimmer.
Check your LED drivers first
The most common Pixie complaint has nothing to do with Pixie: downlights that flicker at low levels, buzz or will not dim smoothly. That is almost always a mismatch between the dimmer and the LED drivers in the lights.
Most dimmable downlights work well. Some do not. A good installer checks every lighting circuit before anything is ordered and tells you which lights will dim cleanly. It is much cheaper to find out on the walk-through than after the switches are in.
Where Pixie makes sense
- Existing homes where rewiring for a wired system would mean opening walls and ceilings.
- Period homes, terraces and apartments where cable access is hard or strata rules make major work difficult.
- Staged upgrades, starting with the living areas, kitchen and main bedroom and adding rooms later.
- Owners who want lighting scenes and schedules, not a whole-home system.
Where Pixie is not the answer
Pixie is a retrofit smart lighting system, and a good one. It is not a whole-home platform. If you want lighting, blinds, climate, security and audio working together from one app and one set of keypads, that is what whole home control is for.
If your house already has C-Bus or Dynalite, Pixie is rarely the right move either. The wired system is usually worth repairing or extending instead. Not sure which you have?
Building a Pixie smart home, step by step
- Walk-through: every switch and light listed, LED drivers checked.
- Priority rooms first: living areas, kitchen and main bedroom.
- Scenes and schedules: named the way you actually use the house.
- Gateway if needed: for control away from home or voice assistants.
- Add rooms over time: each switch is independent, so there is no rush.
Does Pixie need an electrician?
Yes. Pixie dimmers and switches are wired at 230 volts, so in NSW the work must be done by a licensed electrician. That is also why the LED driver check matters. The person installing should be able to tell you what will and will not work on your circuits.
Pixie already installed and playing up?
Lights flickering at low levels, switches that have dropped off the mesh, or an app that lost the house after a new modem are all fixable. Wi-Fi and network changes are behind a lot of app issues. See whole-home Wi-Fi for why. We service Pixie systems installed by others too. Book a service call.
Frequently asked questions
Does Pixie need a hub?
Not for control inside the house. Pixie devices talk to each other over Bluetooth mesh and to your phone directly. A gateway is added if you want control away from home or voice assistants.
Will my existing LED downlights dim properly with Pixie?
Most will, some will not, and it is a driver question rather than a Pixie question. Every circuit should be checked before switches are ordered.
Is Pixie a whole-home smart home system?
No. Pixie is smart lighting. For lighting, blinds, climate, security and audio on one system, you need a whole-home control platform.
Can I install Pixie switches myself?
No. They are wired at 230 volts, so in NSW they must be installed by a licensed electrician.
Can Pixie be added a room at a time?
Yes. Each Pixie switch replaces an existing one, so you can start with a few rooms and add more later.
