Pros/Cons

Smart Lighting

When you add Z-Wave light switches to your home, then you can take advantage of smart lighting. This is the technology that makes it possible for you to remotely control the lights in your home.

Specific Schedules

In addition to making the lights brighter or dimmer or turning them on or off, you have the ability to create schedules and scenes for specific times of day and activities.

Energy Bills

Smart lighting helps you to save money on energy bills and simplifies your life by allowing you to control your home's lighting from anywhere.

Voice Controls

The technology also may integrate with voice-activation controls through Amazon Alexa and Google Assistant.

Wiring

Essentially, there are two categories of smart switches. These are on/off switches and dimmer switches.  While some of these switches must be wired into a box, others are plug-in modules that don't require any wiring at all.

Compatibleness

Many smart light switches take advantage of Z-Wave technology. Z-Wave is a radio protocol that requires a compatible hub that allows your smart devices to communicate with your phone or tablet. Before you choose a smart light switch, it makes sense to ensure that it's compatible with your existing hub.

Additionally, if you want to use your voice to control your smart light switches, then you'll need to make certain that those switches work with your choice of Google Assistant, Amazon Alexa or others.

Three-Way Switches

Z Wave dimmer reviews suggest that it also is wise to consider any three-way switches that you may have installed in hallways or large rooms.

Some smart switches are readily configurable as three-way switches while others are either incompatible or require quite a bit of programming to make them compatible.

Light Bulbs

Give some consideration to your light bulbs as well. For instance, you may need to look into whether or not your existing bulbs will work with the switch you've chosen. If you're using smart bulbs, you may have to switch to dumb bulbs.

How does Z-Wave technology work?

Z-Wave is a wireless technology that enables smart devices to communicate with each other. It does this by building a wireless mesh network that enables various devices to "mesh" together. This is accomplished by sending signals via radio waves at a dedicated frequency. Devices that have Z-Wave technology possess a signal repeater that sends and receives data.

What is a smart light switch?

Smart light switches are one example of network-enabled smart-home devices. With these switches, it's possible to control any hardwired lights by using an app or a virtual assistant. That means that you can turn lights off and on or dim them from anywhere in the world. These switches also enable you to program schedules and scenes.

Do smart light switches need neutral wires?

A majority of smart light switches require a neutral wire. This isn't a concern in most newer homes built after 1970. Older homes may have been built without the requirement for a neutral wire. This means that you may need to find a smart switch that doesn't require a neutral wire, which can be difficult. Additionally, a second hub or bridge may be needed to activate the smart light switch on your network.
