SureSlide vs Decora Smart Companion
Wiring requirement
You must check your wall box wiring before buying. The Leviton SureSlide LED Dimmer Switch requires no neutral wire, which simplifies installation in older homes where neutral lines are often absent. It fits standard wall boxes easily. The Leviton Decora Smart Dimmer Companion explicitly requires a neutral wire for installation. This means you need a complete circuit. If your box lacks a neutral, the Decora Companion will not work as a standalone or companion unit. The SureSlide offers greater flexibility for retrofits without electrical upgrades.
Device role
These devices serve completely different functions in your lighting circuit. The Leviton SureSlide LED Dimmer Switch is a standalone dimmer. You install it as the primary control for your lights. It handles the dimming logic itself. The Leviton Decora Smart Dimmer Companion is not a standalone device. It requires a primary Leviton Decora Smart or Decora Digital dimmer to function. It cannot control lights on its own. It only works as a secondary switch in a multi-location setup. Choose the SureSlide for primary control and the Decora Companion only if you already have a compatible primary switch.
Load capacity
Both devices manage dimming loads, but the SureSlide specifies its capacity clearly. The Leviton SureSlide LED Dimmer Switch supports a maximum load of 150 watts for LED, halogen, and incandescent bulbs. This limit applies to the total connected lighting. The data for the Leviton Decora Smart Dimmer Companion does not list a specific wattage limit. It is designed to work with a primary dimmer that likely has its own load rating. You must rely on the primary device’s specifications for load management. The SureSlide provides explicit load data for planning your bulb count.
Multi-location support
Both products support expanded control across multiple wall switches. The Leviton SureSlide LED Dimmer Switch supports standard 3-way and 4-way wiring setups. You can pair it with compatible 3-way or 4-way switches for expanded control throughout your home. This allows traditional multi-switch operation. The Leviton Decora Smart Dimmer Companion is designed specifically for multi-location applications. It provides access at another wall location, such as staircases or large rooms. It matches the look and functionality of the primary dimmer. Both enable control from multiple points, but via different wiring methods.
Physical dimensions
The physical size of the switch face affects how it fits your wall plate. The Leviton SureSlide LED Dimmer Switch measures 1.80 inches in length and 0.82 inches in width. It has an ultra-slim design that fits standard wall boxes. The Leviton Decora Smart Dimmer Companion measures 2.12 inches in length and 1.43 inches in width. It is slightly wider and longer than the SureSlide. Both share a similar height around 4.12 to 4.13 inches. The Decora Companion is bulkier in width. The SureSlide is narrower. Check your wall box depth and faceplate compatibility before installing either unit.
Which Leviton Dimmer Should You Buy
Renter with no neutral wire in box
You need a dimmer that works without a neutral wire. The SureSlide LED Dimmer Switch fits standard wall boxes easily and requires no neutral connection. This simplifies installation in older homes where neutral lines are often absent. It supports up to 150W for LED or incandescent bulbs, giving you reliable brightness control.
Homeowner wanting multi-location control
You need to control lights from multiple spots like staircases or hallways. The Decora Smart Dimmer Companion allows this when paired with a primary smart dimmer. It requires a neutral wire for installation. The LED locator light helps you find the switch in the dark, and it matches the look of your main dimmer.
User wanting customizable fade and brightness
You want fine-tuned control over your lighting atmosphere. The SureSlide Dimmer Switch lets you customize minimum and maximum brightness levels and adjust the fade-on rate. This allows you to create specific moods, from bright task lighting to a soft ambient glow. It supports 3-way and 4-way wiring setups for expanded control.
User needing companion for smart dimmer
You already have a primary Leviton Decora Smart or Digital dimmer and need an additional switch. The Decora Smart Companion is not standalone; it requires the primary device to function. It lets you turn lights on or off and change brightness from another location. It requires a neutral wire and fits standard wall boxes.

Frequently asked questions
Can I use the Leviton Decora Smart Dimmer Companion to control lights on its own?
No. This device is designed strictly as a secondary control unit. It must be paired with a primary Leviton Decora Smart or Digital dimmer to function. You cannot install it alone to manage lighting brightness or turn fixtures on and off without that main smart switch present in the circuit.
Does the SureSlide dimmer require a neutral wire for installation?
No. The Leviton SureSlide LED Dimmer Switch operates without a neutral wire connection. This design allows it to fit into standard wall boxes easily, making it a practical choice for older homes where neutral lines are often absent from the electrical box behind the switch plate.
What is the main difference in purpose between these two Leviton switches?
The SureSlide is a standalone dimmer built for smooth, reliable LED brightness control without any smart features. The Decora Smart Dimmer Companion is an add-on accessory. Its sole purpose is to provide a secondary control point for an existing primary smart dimmer, rather than operating lights independently.
Is the SureSlide dimmer compatible with smart home apps?
No. The Leviton SureSlide LED Dimmer Switch does not include smart connectivity or app control capabilities. It is designed for users who prioritize simple, physical dimming and reliable operation over remote management or integration with voice assistants and home automation platforms.
Which switch is better for a primary lighting control point?
The SureSlide LED Dimmer Switch is the correct choice for primary control. It functions independently to dim lights directly. The Decora Smart Dimmer Companion cannot serve as a primary switch because it lacks the internal circuitry to control the load on its own and requires a companion smart dimmer.
What colors are available for the Decora Smart Dimmer Companion?
The Leviton Decora Smart Dimmer Companion is available in White, Ivory, and Light Almond. You can select the finish that best matches your existing wall plates and decor. This variety helps ensure the secondary switch blends seamlessly with the primary smart dimmer installed in your home.
Does the Decora Smart Companion have its own LED indicator light?
The provided specifications do not mention an LED indicator light for this model. You should check the product packaging or manual for visual feedback details. The data confirms it is a 1-pack accessory designed for secondary control, but does not list specific lighting features on the faceplate.
