The Leviton Decora Smart Switch Companion is designed specifically for multi-location switching applications and is not intended for standalone use. This accessory unit works in conjunction with a compatible primary smart switch to enable control of a single load from multiple points, making it ideal for hallways, staircases, large rooms, or any area where two or more switches are needed for the same light or set of lights. It operates on a standard 120VAC, 60Hz electrical system and features the familiar Decora paddle design, ensuring seamless integration with existing Leviton Decora wall plates and devices. The companion switch communicates with the primary switch via a wired connection, providing reliable and consistent performance without the need for additional wiring or complex setups.

Constructed with durable thermoplastic materials, the switch offers long-lasting durability and resistance to everyday wear. The paddle actuator has a smooth, tactile feel with a positive snap action, allowing users to easily turn lights on or off from multiple locations. The compact body is designed to fit standard wall boxes, and the included push-in and side wiring terminals accommodate up to 12 AWG copper or copper-clad wire, simplifying installation for both new constructions and retrofit projects. The white and light almond color options complement most interior decors, maintaining a clean and uniform appearance across all switch points.

While the unit itself does not include smart home connectivity or voice control features (those are managed by the primary switch), it serves as an essential component in a complete multi-location smart setup. From a technical perspective, the DD0SR-1RM companion switch is rated for 120VAC, 60Hz, with a maximum load capacity appropriate for standard residential lighting circuits. It is compatible with Leviton’s Decora Smart series primary switches, ensuring the system operates reliably without signal interference or lag. The switch does not contain a radio frequency transmitter or receiver, which contributes to its inherently stable and low-power operation.

The internal contacts are silver alloy for enhanced conductivity and arc resistance, contributing to the unit’s long service life. All components are assembled under stringent quality control processes, and the switch meets UL and cUL safety standards, providing peace of mind for homeowners and electricians alike. At a price point around twenty-nine dollars, this companion switch offers exceptional value for those expanding a multi-location smart control system. It eliminates the need for expensive wireless or battery-operated remote switches, instead leveraging a simple wired connection that is both cost-effective and highly reliable.

The device is an ideal choice for homeowners looking to upgrade their lighting control without incurring high costs or compromising on performance. Whether used in a new home build or as an addition to an existing Decora Smart system, the Leviton companion switch delivers the functionality needed for convenient, multi-point operation. Its straightforward installation and robust construction make it a practical solution for anyone seeking a consistent, user‑friendly experience in controlling lights from multiple locations.
