The Leviton Decora Smart ELV/LED Phase-Selectable Dimmer Switch (Model D2ELV-1BW) offers advanced smart lighting control with Wi-Fi, voice integration and broad load compatibility. With a required neutral connection and phase-selectable design for both ELV and LED fixtures, it’s an excellent choice for homeowners upgrading to intelligent lighting systems while ensuring reliable performance and future flexibility.
Smart-home lighting is no longer a luxury it’s integral to home comfort, energy savings and user experience. The Leviton Decora Smart ELV/LED Phase-Selectable Dimmer Switch (ASIN B0D7MX4D3J) brings advanced control and broad compatibility for lighting upgrades, offering Wi-Fi integration, phase-selectable dimming for both ELV (electronic low voltage) and LED loads, and native support for major voice assistants. A compelling option for homeowners, renovators and smart-home enthusiasts alike.
Key Features & Build Quality
- Phase-Selectable Dimming: One standout aspect of this dimmer is the phase-selectable design, enabling compatibility with both ELV and standard LED (or incandescent) lighting loads. This flexibility makes it well-suited for older homes retrofitting mixed fixture types.
- Wi-Fi 2nd Generation & Smart Integration: The unit supports Wi-Fi connectivity without requiring a separate hub, and can be integrated with voice assistants such as Amazon Alexa and Google Assistant. This adds remote control, scheduling, automation scenes and voice command functionality.
- Neutral Wire Required: Unlike some older smart dimmers, this model requires a neutral line connection, which ensures stable power, avoids flickering and supports better performance particularly with low-wattage LED loads.
- Modern Decora Form Factor: Designed to fit standard Decora-style wallplates, the switch presents a clean, contemporary aesthetic that aligns with modern interior finishes. The tactile toggle/rocker design is familiar while offering the advanced dimmer functionality.
- Reliable Brand & Certification: Leviton is a long-established name in electrical and lighting controls. The technical details show that this switch supports professional-grade installations and meets applicable safety and performance standards.
Performance & Real-World Use
In practical terms, users report smooth performance when installed correctly, with minimal flicker or compatibility issues with LED loads when set up correctly as ELV or LED mode. The smart features remote control, scenes and voice commands—extend the utility beyond simple wall-dimmer functionality. One review summarises:
“Control a wider range of lighting – designed for use with LED and ELV lighting out of the box to add smart dimming control.”
However, as with any smart switch, proper wiring is crucial. Because a neutral is required, older homes lacking a neutral may need additional wiring or alternative models. Also, smart wiring (e.g., 3-way circuits) can introduce complexity. In bright sunshine or high-ambient light, the small indicator LED/markings may not be as visible users should ensure proper setup and wallplate contrast.
Ideal Use-Cases & Audience
- Homeowners upgrading to smart-lighting in one or multiple rooms seeking voice control, scheduling and automation.
- Renovators working in older homes where light fixtures include mixed LED and electronic low-voltage (ELV) types, benefiting from phase-selectable flexibility.
- Smart-home enthusiasts building integrated lighting scenes, mood lighting, vacation away-scenes or remote control.
- Pros or DIYers who prefer high-quality, name-brand electrical controls with broad compatibility and trusted reliability.
Strengths & Advantages
- Versatile compatibility with both ELV and LED loads reduces need for separate dimmer models.
- Strong smart-home integration (Wi-Fi, Alexa, Google) for control, automation and convenience.
- Neutral-wire design ensures performance stability especially with low-wattage fixtures.
- Professional brand with durable design and credible track record.
- Modern Decora-style fits seamlessly into upgraded interiors.
Limitations & Considerations
- Neutral wire requirement: Homes without a neutral conductor in the switch box may need additional wiring or must choose a no-neutral smart switch.
- May be over-featured for simple manual dimming needs; for basic functionality cheaper non-smart models suffice.
- Smart features rely on Wi-Fi, app and subscriptions: users should consider network reliability and compatibility over time.
- Mixed 3-way/4-way wiring setups or older knob-and-tube circuits may require professional installation.
- Although phase-selectable, extremely niche lighting types (very low wattage accent LEDs or transformer-only circuits) may still need manufacturer compatibility check and proper load mode selection.
Conclusion
Overall, the Leviton Decora Smart ELV/LED Phase-Selectable Dimmer Switch (Model D2ELV-1BW) is a very strong candidate for smart-home lighting upgrades across a variety of fixture types. Its phase-selectable capability, Wi-Fi connectivity, neutral-wire design and trusted build quality make it suitable for modern lighting systems. If you’re seeking a versatile, future-proof dimmer for intelligent lighting control and have compatible wiring this switch delivers excellent value and flexibility. For very simple installations, or homes without a neutral, simpler models might suffice but for many households this offers advanced functionality and high compatibility.
