By making the switch to a smart home and replacing the conventional wall switch, you can create a seamless, more eco-friendly living environment.


Technology has changed the way we live. 

You rely on digital devices on a regular basis for everything from work-related tasks to catching up with family and friends from afar. Today, you can even incorporate a no-neutral smart relay switch(Zigbee & Z-Wave compatible) 

or a no-neutral wire smart relay switch (HomeKit-Enabled) to achieve home automation efforts. 

If you’re looking to build a smart home system, understanding why the Zigbee light switch with no neutral can be advantageous can help you turn your standard living space into a smart home. Let’s take a closer look at the benefits of considering the Zigbee switch, and how it can eliminate the need for a neutral wire.

Why turn your living space into a smart home?

Why should you invest in smart light switches for homes? First, consider the main difference between the traditional wall switch and wireless switch.

A traditional wall switch is an electrical device that controls the electrical current of a circuit using a physical switch panel located on the wall, but this may be considered a mechanism of the past. Wall switches only have two states: on and off.

With the introduction of new technology like smart light bulbs and other smart gadgets, these new devices bring additional features to an action as simple as turning on a light in your home. You can control your room’s lighting by adjusting its hue, the brightness and even the duration that it is on. Smart homes bring a fully customisable experience to your living space, making you the true master of the house. 

Additionally, wireless switches that use a mesh network like Zigbee to communicate can replace the need to physically get up to turn the lights on and off. These networks give complete wireless compatibility to all of the power light fixtures within a living space. With wireless connectivity, lights can be controlled from the palm of your hand using an app on your smartphone or a smart button — or even by giving your favorite smart home hub a voice command. Quick and convenient, wireless switches make for a more comfortable living experience.

Move toward total home automation by starting with the smart light switch. 

Finding a smart switch with no neutral wire necessary

No neutral wire system 

One of the most important factors to take note of when you’re buying smart devices is to figure out if your home has a neutral wire or not. For most light switches and even some smart switch applications, the neutral wire is necessary for your smart devices to function. 

However, a neutral wire isn’t always present in every type of home, though more modern homes are more likely to have one. Neutral wires are primarily used to complete the electrical circuit and provide a path back to the transformer, but they can also play a part in feeding your smart switches and other smart devices power. 

This can cause a problem for smart devices that require a neutral wire to operate. When you turn off a switch, the electrical current stops flowing — that’s why a light stays off. But a neutral wire can continue to provide a small electrical current to the smart device, which it can then use to send and receive commands. Many smart switches and smart appliances therefore need a neutral wire in order to keep receiving passive signals at all times.

A good way to find out if your home has a neutral wire is to take a look behind your light switch by unscrewing the faceplate and seeing how it’s wired. Homes built in the UK before 2004 have black neutral wires. If the home was built post-2004, your neutral wires should be blue to align with European standards. The absence of this wire in your home can throw a wrench into your smart home plans.

But whether your home has a neutral wire running through it or not, there are a few smart devices that don’t require one at all — simplifying your smart home building process.

EVVR’s In-Wall Relay Zigbee light switch is one such device, requiring no neutral wire to run. Without the neutral wire, homeowners are given the opportunity to utilise more smart lights throughout their living spaces without worrying about rewiring the electrical system within the walls and ceilings. A no neutral wire-required wireless switch makes functionality the top priority by eliminating the need for wiring without compromising on the performance.

The benefits of Zigbee light switches with no neutral

By making the switch to a smart home and replacing the conventional wall switch, you can create a seamless, more eco-friendly living environment. 

Some of the advantages of the Zigbee light switch with no neutral include:


Increase security measures by using smart switches, which you can control from the palm of your hand at any time. That means anyone with access can turn the lights on or off without being home. This can be specifically helpful when on vacation or out of town for business: Homeowners can turn the lights on from afar to create the illusion that they’re in the house. They can also set the smart switch on a schedule or manually turn the lights on and off on their own time. 

Saved money.

Homeowners can save money with the smart switch by programming when the lights go on and off. With the opportunity to control the lights from any location at any time, homeowners are given the chance to save electricity and conserve energy over time. Plus, one smart light switch can simultaneously control multiple lights at once, which could ultimately save on replacing smart bulbs.


One of the biggest advantages of changing to the Zigbee light switch with no neutral is its opportunity for convenience. Gone are the days of getting out of bed or leaving the couch to turn off the lights or manually adjust the dimmer. Controlling lights with a smartphone instead is the better option. Homeowners can even set up an automation with their favorite smart assistant, like Amazon Echo, Alexa or Samsung SmartThings, to turn their lights on and off. Even better, they can use a simple voice command to get the job done.

Enjoy a dimming option.

By bringing a smart light switch into your home, you can turn down your bulb brightness with ease by introducing a faux dimmer switch into your home. This aesthetically pleasing advantage offers an easier and more convenient way to turn the lights down with an application instead of buying and installing a separate dimmer.

Efficient replacement option.

Rewiring your entire house if you don’t happen to have a neutral wire can be a time-consuming, painstaking and expensive process. With a Zigbee light switch, you don’t have to completely replace your entire lighting system if you want to create a smart home. The Zigbee light switch with no neutral can be incorporated into the already existing mechanical system for a smart and efficient option. Additionally, smart light switches can be used with all types of lighting and socket options, which means they will most likely work with the current voltage requirements and light fixtures.

Determining whether the conversion to a smart home makes sense varies from one homeowner to the next. But with so many advantages, introducing a smart switch can be the perfect upgrade solution to an outdated home.
