Who it fits
Good fit for
You should choose this device if you need to add on/off control to existing multi-location lighting or ceiling fan circuits. It fits well in hallways, staircases, or large rooms where multiple entry points require switching. The unit is ideal for users who already own a compatible Leviton Decora Smart or Digital primary switch and want to extend basic control. It also suits those who prefer physical switches over app-only management for routine toggling.
Who should skip it
You should look at another option if you need a standalone smart switch. This companion unit cannot control devices independently. It lacks Wi-Fi, Bluetooth, or Z-Wave connectivity for remote app control. It also does not include a dimming function or fan speed control. If your current circuit has only one switch location, this device will not work. You need an existing compatible primary switch for this unit to power and function correctly.
Verdict: This companion unit effectively extends basic on/off control to additional wall locations when paired with a compatible primary switch. It is a practical solution for multi-location wiring but offers no independent smart features.
Key specs explained for Leviton
Circuit Type: 3-Way, Multi-Location
This specification indicates the device is designed to operate within a 3-way circuit configuration. It allows you to control a single light or fan from two or more separate wall switch locations. This setup is ideal for areas like staircases, long hallways, or large rooms with multiple entrances. You must pair this companion unit with a compatible primary smart switch to enable this multi-point control functionality.
Switch Function: On/Off Switch
The unit provides basic on and off toggling capabilities only. It does not support dimming or variable speed control for fans. You use this companion to turn connected loads fully on or fully off from a secondary location. If you require adjustable brightness or fan speed, you must rely on the primary smart switch or dimmer installed at the main location, as this companion unit lacks those advanced modulation features.
Wiring Requirement: Neutral or load side wiring required
Installation requires either a neutral wire or the use of load-side wiring to complete the circuit. This technical detail determines the complexity of your electrical work. You must verify your existing wall box contains the necessary wiring before purchasing. If your current setup lacks a neutral wire, you may need to use load-side wiring or consult an electrician to ensure safe and compliant installation for this multi-location control device.
Model: DD0SR-1RM
This alphanumeric code identifies the specific product variant within the Leviton Decora Smart lineup. You use this model number to verify compatibility with your existing primary smart switches or dimmers. It ensures you are purchasing the correct companion unit for your specific home automation setup.

Physical design and build details
The listing describes the Leviton Decora Smart Switch Companion as a companion unit, not a stand-alone device. It measures 1.4 inches in width, 4.13 inches in height, and 1.7 inches in length. These dimensions match standard single-gang wall plates. The unit is sold in a 1 pack. It arrives with no color, meaning you must supply your own faceplate to match your existing decor. The listing notes that you can change the color at any time with a new faceplate. Options include white, ivory, light almond, gray, black, and brown. This allows you to blend the switch into your room’s aesthetic without replacing the entire mechanism.

The layout is simple, featuring a standard toggle interface. This design prioritizes reliability over complex features. It is ideal for staircases, long hallways, or large rooms where you need access from multiple entrances. The unit replaces an existing 3-way switch. Installation requires a neutral wire or load side wiring. This physical setup ensures you can control your lights or ceiling fans from different locations in your home.
Setup and daily operation details
