Smart Light Switch FAQ​

Best Smart Light Switch

There are a lot of smart switches on the market, and each has its own unique features and requirements.

This variety in product creates a lot of questions from consumers, like you, about what is the best product for your smart home.

It also creates questions about the basics of smart switches and smart lights.

We’ve compiled this shortlist of questions that are frequently asked by people who are starting down the path of upgrading to a smart home.

Doing the research to answer your questions can be more work than installing your smart switch, so we’ve done the work for you, to help make your smart home adventure a little easier.

How Does a Smart Light Switch Work?

A smart switch is a direct replacement for the traditional light switches in your home.

They work to turn off and on lights and other appliances in your home that are traditionally operated using a “light switch”.

Smart switches rely on a radio transmitter to send signals to other switches in your home, as well as allowing you to connect them to your home network, 
smart hub and smart phone or tablet.

This radio transmitter is similar to the radio transmitters that are installed in things like your smart thermostat, smart irrigation timers, and even your video doorbell.

This connectivity allows you to control your light switches in a couple of ways.

First, and fortunately for your guests, a smart switch looks just like your normal light switch, so you can toggle the switch up and down to turn on or off your lights or other appliances.

The second way you can control your smart switches is using an app on your phone. Some switches have their own app, while others utilize an app like Amazon’s Alexa.

These apps allow you to remotely access your light switches from across the room, or from across the globe.

This remote ability gives homeowners a greater sense of safety, since you can easily turn on lights, even when you’re not home.

The third way that smart switches function is through your smart hub.
Doing your research before you buy, will ensure that you purchase switches that easily sync with your smart home hub.

From this hub you can easily request that lights are turned on or off, dimmed or even your ceiling fan is turned on, with a simple voice command.

For individuals that have limited mobility, this feature can be a real life changer, when it comes to safety in their home.

Do all Smart Light Switches Need a Neutral Wire?

No, not all smart light switches need a neutral wire.

This is good news if you live in an older home that was built before the National Electric Code required all light switches have a neutral wire.

However, not having a neutral wire adds extra challenge when you are trying to connect your switch to your home network. It’s not impossible but will require a bit of additional work.

Most smart switches require a neutral wire because they are powered all the time. This is how they are able to communicate with your home network or connect to apps like Alexa.

The neutral wire allows the circuit within the switch to stay on for the networking capability, even when the toggle for the switch that powers the light is off. Without the neutral wire, when you turn off the light, the smart switch can no longer communicate with the network.

Smart switches that do not require a neutral wire, have a microprocessor inside of the switch that allows them to maintain connectivity with the network.

There can be some challenges with installing these sorts of switches, so before you go pulling out the switches in your older home, consult with an electrician.

And lastly, if you aren’t confident with doing electrical work in your home, whether its older or fairly new, make sure you hire a good electrician to do this work.

You can cause harm to your home’s electrical system and potentially cause serious injury to yourself if you don’t know what you’re doing.

Do Smart Bulbs Use Electricity When They’re Off?

Yes, smart bulbs do use electricity, even when they are turned off.

So why, you might ask, would you install smart bulbs as a way to improve energy efficiency in your home?

Well, first, you need to understand that the amount of energy that your smart light is using when it is off, is less than your television or DVD player uses when it is off.

For the most part, all appliances still use a bit of electricity even when they appear to be turned off. Your smart bulbs are kind of like tiny appliances.
They have electronics inside of them that allow them to maintain connectivity to your network and apps like Alexa or Google Home Assistant.

This tiny bit of electricity, is so small that you likely wouldn’t notice the demand on your normal electric bill.

What you do need to remember is that almost all smart bulbs are LED, which are highly efficient.

The amount of energy savings that you are receiving from the switch to LED lights in your home, more than makes up for the slight increase in demand from both your smart bulbs and your smart switches.

Do I Need a Hub for Smart Switches

First, when answering this question it is important to distinguish between the two different types of hubs that your smart switches might need.

Understanding this distinction is the difference between getting the things you need to make your smart switches work, and getting added item that may or may not be necessary, depending on the switch brand you choose.

So, let’s look at the first scenario, the hub that is necessary to make your smart switches work.

This is a specific hub that is necessary if you are installing smart switches that do not require a neutral wire for installation.

These switches also require a hub that sits in the box with your switch that keeps the power to your smart switch, so that it can be continuously connected to your home’s network.

In this situation, without this particular hub, your smart switches will not work, and you’ve spent a bunch of money on an extra fancy, normal, light switch.
In the case of a switch that doesn’t need a neutral wire for installation, a hub is a must.

Now, for the other scenario, the hub may or may not be necessary. In this case, we’re talking about a home smart hub.

This is a kind of central control unit for all of your home automation devices. Most smart switches do not require a smart hub for their operation.
