Smart light switches are an important part of the smart home system. If you fancy lights and have several on your ceiling, you might want to consider adding smart light switches to give your house a smart home addition.
With smart lights, you’ll be required to switch them on manually, every time. But with smart light switches, you can automate your lights to switch on and off at certain times like before you get home. You can also configure them so that they turn on when other smart home appliances are triggered for instance, when the security system detects an intruder.
Additionally, you can control them via a voice assistant like Amazon Alexa and Google Assistant. They give you convenience from automation, timing, and scheduling. Sounds like something you’d like to try? We came up with a list of the best light switches in 2020 to make the buying process easier.
What is a Smart Switch?
A smart switch is a light switch with automation functionalities. It still resembles the normal switches including how it plugs and the appearance, but unlike the other switches, you don’t have to fumble around in the dark looking for the switch.
You can control the switch on your phone or with your voice saving you from stumbling and hitting things as you look for the switch.
Other differences include;
- Their design is more detailed, with some having extra buttons for dimming or brightening the light, while others may have extra light indicators and sensors.
- They use radio waves to connect to a wireless network. They can sync with other smart home devices as they are part of IoT.
How Do Smart Switches Work?
Smart switches use radio waves to connect and communicate with each other on your network. You then have access to the ‘smart’ feature through an app on your smartphone.
The app connects to WiFi, Bluetooth, or smart home wireless protocol like Z-Wave and Zigbee to control the switches remotely. You can still toggle the wall-built switch, especially when your phone is far but the best smart light switch allows you to control your lights from thousands of miles away.
To give you greater control, you can opt for a home automation controller such as Samsung SmartThings or use your voice via a smart speaker such as Amazon’s Echo.
There’s no need to worry whenever you leave your lights on when you go to work or for a vacation in another country. Just use your phone and switch them off.

How To Install Smart Light Switch
While some smart switches may require professional installation, others are easy to install and you can do it yourself. They do not require electrical experience especially the wireless ones that do not require a neutral wire.
Steps to Installing a Smart Light Switch
- Learn your existing wiring setup and type of switch. To examine the wiring, you will need to open up the existing switch. Turn off the lights first at the fuse box to avoid electrocution. Most wirings have an in wire, an out wire, and a ground wire, but older houses built before 1980 may lack the neutral wire. It is a white wire that some switches need for you to install them, but if you don’t have it, you can still buy a switch that does not require the neutral wire.
- Go ahead and buy a smart switch of your choice but consider the neutral wire requirements.
- Remove the existing switch. Make sure the power is off before you start removing and disconnect wire by wire taking note of every wire.
- Connect the smart switch. Connect the in wire to the in wire, out wire to out, ground to ground, and neutral to neutral. Use wire connectors to secure your connections and don’t leave any naked wire in the box.
- Return the wire connections in the box and put the smart light switch in place.
- Connect the smart light switch to WiFi, install the required app, and connect to the network.
How Do Smart Bulbs Work With Switches
Smart bulbs work like the regular, standard bulbs. The only difference is that you require a smartphone app or a mobile device for them to work. Usually, you’ll also need a home automation system such as WiFi or Bluetooth for the bulbs to connect and communicate through the network.
Smart bulbs will still work with the traditional switches. The switches turn the light on or off. Instead of doing it manually, smart switches can automate the process and even allow you to control your lighting remotely.
A few smart bulbs’ brands might require you to buy specific hubs such as Philip Hue’s smart bulbs, which require Philip Hue Bridge.
Basically, switches are just an old-fashioned way of switching the smart lights on and off, although the smartphone apps offer more control.
Smart light switches are an ideal way to automate lighting in your home. You can set most of them to turn the lights on and off at certain times. The remote controlling functionality is useful, especially if you forgot to switch off the light when leaving.
Most smart light switches are compatible with major smart home assistants like Amazon Alexa, Google Assistant, Apple HomeKit, and their corresponding apps. Other features include motion and light detectors, dimmer, among others.
When purchasing, check the factors you need to consider and their features to get the best smart light switch.
