Okay, you're looking to add a remote switch to an existing light, and you don't have power at the remote location. That's a common scenario. Here's a breakdown of how to do that with Leviton or Lutron, focusing on the solutions that don't require running new wires to the remote location and don't offer dimming

The Core Concept: Wireless Communication

The key here is using a system where the remote switch communicates wirelessly with a smart switch at the light fixture itself.

The Two Main Solutions

Both Leviton and Lutron offer solutions that fit your needs. You'll need both a smart switch that goes at the location of the actual light, and a remote switch that communicates wirelessly.

Option 1: Lutron Caseta Wireless Advantages



Extremely Reliable

Lutron is renowned for its robust and reliable wireless technology (Clear Connect).

Broad Compatibility

Caseta integrates well with many smart home systems (Apple HomeKit, Alexa, Google Assistant, etc.).

Easy Setup

Their app is user-friendly, and the initial setup is generally very straightforward.

Pico Remote Options

Lutron's "Pico Remotes" are versatile. They can be mounted on a wall (with an adapter), placed on a tabletop stand, or even carried around.

No Neutral Wire (Sometimes)

Some Lutron Caseta switches do not require a neutral wire, which can be a huge benefit in older homes. Check the model you purchase to confirm. The PD-5ANS model does not require a neutral wire. The PD-6ANS model does require a neutral wire.

Disadvantages



Cost

Lutron Caseta is generally more expensive than Leviton's equivalent.

Hub Required (Generally)

To access smart features and control the switches via an app or voice assistant, you'll likely need a Lutron Smart Bridge (or Smart Bridge Pro). This is not required if you only want to control the light with the remote Pico remote.

How it Works


Install a Lutron Caseta Smart Switch

Replace the existing light switch with a Lutron Caseta switch. This switch will control the physical on/off of the light. Choose a model that doesn't require a neutral wire if your existing wiring doesn't have one.2.

Install Pico Remote at remote location

Mount the pico remote at the new remote location with a Lutron pico mounting adapter (sold seperately). You can connect the pico remote directly to the Caseta switch without using the Lutron Smart Bridge hub.3.

(Optional) Set up Lutron Smart Bridge

If you want to control the lights via the Lutron app, or integrate with other smart home systems, connect the Lutron Smart Bridge to your router and follow the app's instructions.4.

Pair the Remote

Follow the Lutron Caseta instructions to pair the Pico Remote to the Caseta switch.

Components to Buy (Minimum)

Option 2: Leviton Decora Smart Wi-Fi Advantages



No Hub Required

Leviton Decora Smart Wi-Fi devices connect directly to your home's Wi-Fi network, so you don't need a separate hub.

Lower Cost

Generally less expensive than Lutron Caseta.

Works with Alexa, Google Assistant

Integrates with popular voice assistants.

Disadvantages



Neutral Wire Required

Leviton Decora Smart Wi-Fi switches require a neutral wire. This can be a problem in older homes.

Wi-Fi Dependent

Relies on your home's Wi-Fi network. If your Wi-Fi is unreliable, the switches may not function correctly.

Potentially Less Reliable

While Leviton has improved, some users report that their wireless implementation isn't quite as rock-solid as Lutron's.

How it Works

Install Leviton Decora Smart Anywhere Switch Companion

Install the Decora Smart Anywhere Switch Companion at the desired remote location. The companion switch is a battery-powered switch that wirelessly links to the main Decora Smart switch.3.

Connect to Wi-Fi

Follow the Leviton app instructions to connect the smart switch to your home's Wi-Fi network.4.

Pair the Remote

Follow the Leviton Decora Smart instructions to pair the Anywhere Switch Companion to the Decora Smart Wi-Fi switch.

Important Considerations & Steps



Neutral Wire

Crucially, check if you have a neutral wire in the existing switch box. It's usually a white wire, and it's usually connected to other white wires in the box. If you don't have a neutral wire, Lutron Caseta's PD-5ANS model is a better bet.

Wiring Safely

If you're not comfortable working with electrical wiring, hire a qualified electrician. Turn off the breaker to the circuit before working on any wiring.

Read the Instructions

Both Leviton and Lutron have excellent documentation and videos. Read the instructions carefully before starting any installation.

Compatibility

Make sure that the switch you choose is compatible with the type of lighting you're controlling (incandescent, LED, etc.).

Wi-Fi Signal Strength (Leviton)

If you choose the Leviton Wi-Fi option, make sure you have a strong Wi-Fi signal at the switch location.

Which One to Choose? Lutron Caseta

If you value reliability, easy setup, and don't have a neutral wire, Lutron Caseta is probably the better choice, even though it's more expensive. The Pico remote ecosystem is very versatile.*

Leviton Decora Smart Wi-Fi

If you want to save money and have a neutral wire available, Leviton Decora Smart Wi-Fi can be a good option. However, be prepared for potentially more troubleshooting if your Wi-Fi network isn't robust.

Final Recommendation

For ease of use, reliability, and especially if you don't have a neutral wire, Lutron Caseta with a Pico remote is the recommended approach. It's worth the extra cost for the peace of mind.Always consult with a qualified electrician if you're not comfortable with any of the electrical work involved. Good luck! Flag for review
