10 Best Smart Light Switches 2025 in the United States

The Lutron Diva Smart Dimmer Light Switch is a strong choice if you're looking to smarten up your lighting without complicated wiring. It works with a broad range of smart home systems like Alexa, Apple Home, and Google Assistant, but you’ll need the Lutron Smart Hub to connect everything. It supports dimming for LED bulbs up to 150W, plus incandescent and halogen bulbs, giving you smooth control with a slider and a soft-glow bar right on the wall.

One big plus is that it doesn’t require a neutral wire, which means it can fit into most homes, including older ones where neutral wires might be missing. Installation is fairly straightforward for a smart switch, and it supports single-pole and 3-way setups – the latter can be done easily by adding a Pico remote (sold separately) without extra wiring. You can control your lights via the app, voice commands, or the wall switch itself, and create schedules or scenes for convenience. The switch also offers a 'Smart Away' feature that turns lights on and off randomly, which helps keep your home looking occupied when you’re away.

It doesn’t have built-in energy monitoring, so if tracking energy usage is important to you, this switch won’t provide that data. Also, to get the full range of smart features, you must invest in the Lutron Smart Hub, which adds to the overall cost. This switch is ideal if you want reliable, easy dimming and broad smart home compatibility without rewiring, but it’s less suited if you want integrated energy tracking or prefer a hub-free system.

The Kasa Matter Smart Dimmer Switch offers a good mix of functionality and ease for those looking to streamline their smart home experience. Its standout feature is the seamless compatibility with various platforms like Apple Home, Alexa, Google Home, and SmartThings, enabling a unified smart home environment. The switch also supports voice control through Siri, Alexa, and Google Assistant, making it convenient for hands-free use. This is especially useful when entering a dark room or when your hands are occupied.

In terms of dimming capabilities, the switch allows for precise control over light intensity from 1% to 100%, which can be managed through voice commands, the app, or manual adjustments. Users who want flexibility in lighting will find this feature particularly appealing.

Installation is simplified with the Kasa app providing a step-by-step guide, although a neutral wire is required, which could be a limitation in older homes without this wiring. The requirement for a standard 2.4GHz Wi-Fi connection is typical for smart devices but worth noting for those with dual-band routers.

While the switch includes advanced scheduling and timer options, the lack of direct energy monitoring could be a downside for users looking to track energy consumption directly through the switch. The Away Mode feature, however, adds a layer of security by randomly switching the lights on and off, potentially deterring intruders while you're away.

The Kasa Matter Smart Dimmer Switch is well-suited for users seeking a flexible and compatible smart lighting solution, though those interested in energy monitoring might need additional devices or solutions. Its guided installation and versatile control options make it an accessible choice for both tech-savvy users and beginners.

The Kasa Smart Dimmer Switch HS220P3 is a solid choice for people looking to upgrade to smart lighting with easy voice and app control. It works well with Amazon Alexa and Google Assistant, letting you adjust lighting hands-free or via the Kasa app from anywhere. The dimming feature allows smooth brightness control from 0% to 100%, making it easy to set the perfect mood or schedule lights to gently wake you up.

Installation requires a neutral wire and a 2.4GHz Wi-Fi connection, so it’s best suited for homes with compatible wiring; if you’re unsure about electrical work, consulting an electrician is recommended. The switch doesn’t need a separate hub, simplifying setup and reducing extra devices. Though it lacks energy monitoring, its app-guided installation and simple controls make it user-friendly for most homeowners.

If you want a reliable, voice-controlled dimmer without additional hubs and have the right wiring, this 3-pack option offers good value and convenience.
