Legrand Home Smart Lighting for Apple HomeKit

 | Frequently Asked Questions

How can I remotely control my devices 

when I am away from home?

HomeKit products require an iPad, HomePod, or 

Apple TV set up as a home hub in order to remotely 

access your devices or set up automations. 

Do I need a neutral wire to install 

Legrand Home devices?

Yes. Legrand Home devices require a neutral 

wire to support the small amount of power 

needed for them to respond to commands from 

the app even when devices are turned off.

How do I know if my Smart Dimmer will 

work with my home’s fixture or bulb?

The Legrand Home Smart Dimmer is a patented 

Tru-Universal dimmer. Unlike other dimmers, 

it is guaranteed to dim virtually any dimmable 

light bulb on a standard 120V, 60 Hz circuit.

What is the little toggle switch on 

the side of my Smart Dimmer?

It is called an air gap switch and it physically 

disconnects any power from reaching the lighting load 

that is connected to it. It is a UL requirement for safety.

Can I add or replace a 3-way device 

with a Legrand Home device?

Legrand Home features in-wall master and remote 

devices. For multi-way operation, you will need ONE 

master device. You can add multiple remote devices 

and pair it with the master for multi-way operation.

I am having difficulty setting 

up my remote devices.

If you were able to successfully setup your master 

switch or master dimmer device, but are having 

difficulty setting up your remote devices, check your 

router’s settings. Under advanced settings, if you have 

an AP isolation feature, ensure it is disabled. Second, 

ensure if multicast routing (IGMP Proxying) is enabled.

What apps can I use to control my 

Legrand Home products?

We recommend using the Apple Home app for 

setup and use. However, you will need to use 

the Legrand Home app if you want to link your 

devices to Alexa or the Google Assistant. 

If you need to use reverse phase on our Tru-Universal 

dimmer, you will need the Legrand Home app.

Firmware updates are only available 

through the Legrand Home app.

What if I have multiple 

wireless Access Points?

Multiple access points have no negative 

impacts on the system.

How much bandwidth does 

the Wi-Fi system use?

The data size of the commands that are used 

to send and receive controls on devices is very 

small- just a few kilobits per message.

Can used Legrand Home devices be installed?

It is not recommended unless you know that the 

devices have been factory reset. Additionally, 

you would want to be certain that the original 

installer had properly installed the wiring 

device and not damaged it in any way.

How many devices can I support?

We recommend 20-40 devices in a given home. 

While a Wi-Fi system can theorteically support more 

devices, many routers  and access points can only 

support a limited number of devices on the network.
