The Lutron Diva Smart Dimmer Switch is a strong choice for anyone looking for a smart dimmer that doesn’t require a neutral wire, making it suitable for older homes where neutral wiring isn’t available. It supports up to 150W of dimmable LED lights as well as incandescent and halogen bulbs, but it’s not designed for low voltage lights like track or landscape lighting. One of its main strengths is wide compatibility—it works with popular smart home systems such as Alexa, Apple HomeKit, Google Assistant, Ring, Serena shades, and Sonos, but it does require the Lutron Smart Hub to connect and control these features. The dimmer control is smooth and precise, featuring a soft-glow light bar and a slider for easy adjustment. Installation is relatively straightforward, and it’s designed for both single-pole and 3-way setups, with the option to use Pico remotes for wireless control without additional wiring. This makes it flexible and user-friendly for controlling multiple bulbs with one switch.

Energy monitoring is not included, which could be a downside if you want to track power use. Also, you’ll need to buy the separate Lutron Hub and possibly wallplates or remotes for full functionality, which adds to the cost. This Lutron Diva model is well suited for those seeking a reliable, easy-to-install smart dimmer that works with many smart home platforms and does not require a neutral wire, especially for standard lighting loads.

One of its standout features is that it does not require a neutral wire, making it suitable for older homes where this might be an issue with other smart switches.

This switch is capable of controlling various types of bulbs, including LED, incandescent, and halogen, up to 150W and 600W respectively, allowing you to integrate it with existing lighting fixtures without needing to change your bulbs. Installation is straightforward, with options for 3-way setups and comprehensive support available through videos and technical assistance. However, it does require a smart hub (sold separately) to access full functionality and integrate with other smart devices. This can be seen as an additional cost and setup step.

Additionally, while it offers dimming capabilities, it is not rated for low voltage applications like track or landscape lighting, limiting its use in some specialized lighting scenarios. The wallplate is not included, which may necessitate an extra purchase for a complete installation. In summary, the Lutron Caseta Smart Lighting Dimmer Switch Kit is an excellent choice for users looking for a reliable, easy-to-install smart switch that works well with a variety of smart home systems, but keep in mind the need for additional components for full functionality.
