Adding a secondary light switch to control an existing light can be a convenient home improvement project. With a secondary switch, you can turn lights on and off from two different locations instead of having to walk back to the original switch every time. While hardwiring a new switch used to be the only option, technological advances have made it possible to install secondary light switches without running new wires. There are a few methods you can use to set up a secondary light switch without wiring, depending on your goals, budget, and how tech-savvy you are.

Considerations for Adding a Secondary Light Switch
Before diving into the specifics of how to wirelessly add a secondary switch, it’s helpful to understand a few key factors to consider:
Location
Think about where you want the new switch located in relation to the original switch and light fixture. Closer proximity makes for an easier wireless setup.
Compatibility
Make sure the wireless system and secondary switch you choose are compatible with your existing electrical setup. Most don’t require rewiring but do need a neutral wire.
Single Pole vs. 3-Way
Standard light switches are called single pole. 3-way switches control lights from two locations already. Wireless switches can work with both, but it’s good to know your setup.
DIY vs. Pro Install
Wireless switches are designed to be easy DIY installations, but you may want to hire an electrician if you don’t feel comfortable working with electrical.
Cost
Wireless switches and smart home kits range in price from $20 into the hundreds. More advanced features and smartphone control cost more.
Method 1: Smart Switch Kits
One of the most popular options for adding a secondary light switch is a smart switch kit. These typically include smart wireless switches and a central hub or bridge that enables communication between the switches. Many models work with voice control from Alexa, Google Assistant or Siri as well. Here are some key things to know:
Brands
Top brands of smart switch kits include Lutron Caseta, Leviton Decora Smart, GE Enbrighten, and Belkin Wemo. They range from $100-$200 for the initial kit.
Ease of install
Smart switch kits are designed for easy DIY installation. You simply replace your existing switch with the smart wireless switch and connect the hub.
Smart home integration
Many models work with leading smart home platforms so you can control lights by voice or app without having to run new wires.
Smart features
Beyond secondary control, smart switches offer features like scheduling, dimming, motion sensing, remote access, and integration with other smart devices.
Considerations
You’ll need a hub for most smart switch kits, which adds some cost. Also consider smart home compatibility if you want voice or app control.
Method 2: Wireless Light Switches
For a more budget-friendly and stripped down approach, you can opt for a simple wireless secondary light switch that doesn’t offer all the bells and whistles of a smart switch kit. Here’s an overview:
Types
– Remote controlled: basic wireless on/off switch
– Motion activated: switch attaches to wall and lights turn on with motion detection
– Outlet switch: plug light into wireless outlet switch for remote control
DIY Install
Wireless switches use adhesive or screws to easily mount to walls without wiring. The remote pairs with a wireless receiver you plug into the light’s outlet.
Range and Batteries
Basic models have shorter range from 30-50 ft between the remote and receiver. Remotes run on small batteries that last 6-12 months.
Cost
Individual wireless light switch remotes can cost as little as $15-25 per remote. This is the cheapest route for adding secondary control.
Limitations
No smartphone control, scheduling or other fancy features. Range may be limited compared to more advanced options.
Method 3: Smart Bulbs
If you have smart bulbs like Philips Hue or LIFX, you can control them from a secondary location without running wires. Here’s how smart bulbs allow wireless control:
Built-in Wireless Control
Smart bulbs connect directly to your WiFi network and can be controlled by smartphone app without the need for hubs or wiring.
Smart Speaker Compatibility
Most smart bulbs work with Amazon Alexa, Google Home, and Apple HomeKit. This enables wireless voice control.
Remote Access and Automation
From the app, you can turn lights on/off from anywhere, set schedules, rules and routines. No wires needed.
Smart Switches as Secondary Control
Add a smart switch in a second location and connect it to your smart home platform to control your smart bulbs remotely.
Considerations
Smart bulbs are more expensive than basic wireless switches. You’ll need to replace existing bulbs with smart bulbs to take advantage of wireless control.
Choosing the Best Wireless Secondary Switch
With several good options for wireless secondary switches, here are some tips for selecting the right one:
Consider your budget
– Smart switch kits provide the most functionality but cost over $100.
– Basic wireless switches are the most affordable at $20 or less.
– Individual smart bulbs can be added over time for budget-friendly smart lighting.
Think about additional features you may want
– Smart switches allow app control, automation, scheduling and voice control.
– Basic wireless switches just provide simple remote on/off function.
Factor in your smart home ecosystem
– If you already have Alexa, Google Home, Apple HomeKit or a hub like SmartThings or Wink, look for compatible smart switches.
– Basic wireless switches work independently without a smart home setup.
Account for DIY comfort level
– Advanced smart home configurations may warrant a professional.
– Wireless switches are designed for easy self-installation.
Check wireless range and limitations
– Basic wireless switches have 30-50 ft range between remote and receiver.
– Smart switches typically have wider wireless range.
Installation Guide
Once you’ve chosen the right wireless secondary switch for your needs and budget, it’s time to install it. Here are some step-by-step installation guides for the main types of wireless light switches:
