10 Best No Neutral Wire Smart Switch 2025 in the United States

The Kasa Matter Smart Dimmer Switch is a solid option for those looking to enhance their smart home setup, particularly if you appreciate voice control and dimming features. One of its standout strengths is its compatibility with multiple platforms, including Apple Home, Alexa, Google Assistant, and SmartThings, thanks to the Matter protocol. This means you can control your lights easily no matter what ecosystem you prefer, making it versatile for various users. Additionally, the smart dimming capability allows you to adjust the brightness from 1% to 100%, either through touch, the app, or voice commands, which adds convenience especially in situations where you might have your hands full.

Another plus is its remote control feature via the Kasa App, enabling you to monitor and control your lights from anywhere—a fantastic security feature when you’re away from home. The advanced scheduling and timer options are particularly useful for automating your lighting, including an 'Away Mode' that can help deter intruders.

This smart dimmer switch is best suited for individuals looking to integrate dimming capabilities into an existing smart home setup while enjoying the flexibility of cross-platform control.

The Lutron Diva Smart Dimmer Switch for Caséta is a solid choice for anyone needing a smart dimmer that works without a neutral wire, making it suitable for older homes or those without updated wiring. It supports standard 120V circuits and can handle single-pole and 3-way setups using additional accessories. Installation is relatively straightforward for those familiar with basic wiring, though it requires hardwired connection and the use of a separate smart hub for app or voice control.

The dimmer offers smooth, precise light adjustment through a slider and a soft-glow bar, plus a handy preset feature to return lights to your favorite brightness. Its compatibility is impressive, working with popular smart home systems like Alexa, Google Home, Apple HomeKit, Ring, and Sonos when paired with the hub. However, the switch does not include built-in energy monitoring, which some users might find limiting if they want to track power usage. Control options are flexible—you can operate lights from the switch itself, your phone app, voice commands, or a separate Pico remote.

The smart away feature adds security by randomly turning lights on and off while you’re away, but the need for the Lutron hub sold separately adds to the cost and setup complexity. While the dimmer matches classic paddle-style switches for a neat look, buyers should note the coordinating wallplate is not included. This dimmer is well suited for those looking for reliable, no-neutral-wire smart lighting control with wide smart home compatibility and easy dimming, though it may not satisfy users seeking built-in energy tracking or a purely hub-free experience.

The Lutron Caseta Smart Lighting Original Dimmer Switch Kit is a versatile smart switch that excels in several areas. It is compatible with major smart home ecosystems like Alexa, Apple HomeKit, and Google Home, making it a flexible choice for those already invested in smart home technology. The kit includes a wireless Pico remote for easy control from anywhere in the house, which adds significant convenience. 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.
