10 Best Alexa Light Switches 2025 in the United States

The Kasa Smart Dimmer Switch HS220P3 is a solid choice for anyone looking to add Alexa or Google Assistant voice control to their lighting without needing a separate hub. It works on a standard 2.4GHz Wi-Fi network and offers convenient voice commands and app control from anywhere, which is great for modern smart homes. The switch requires a neutral wire for installation and is designed for single-pole setups, so it’s best suited for homes that have this wiring already. The installation is guided through the Kasa app, but if you're not comfortable with wiring, getting an electrician is wise.

The dimming feature is smooth, ranging from 0% to 100%, with easy-to-use physical buttons and app controls, including handy shortcuts like double-click to fade off. This makes it ideal for creating custom lighting moods and schedules, such as waking up gently with a soft glow. The design is practical and compact, fitting standard switch plates without bulk.

A limitation is the need for a neutral wire, which some older homes might lack, limiting where you can install it. Also, it only supports 2.4GHz Wi-Fi, so it won’t connect to 5GHz networks. For users seeking a reliable, voice-controlled dimmer that’s easy to manage via an app and doesn’t require extra hardware, this Kasa switch is a good match—especially for those comfortable with a bit of DIY or willing to hire help for installation.

The Lutron Caseta Original Smart Dimmer 3-Way Switch Kit offers a versatile solution for smart home lighting. One of its key strengths is compatibility with multiple smart home devices, including Alexa, Google Home, and Apple, making it a great choice for those who already use these ecosystems. The inclusion of a Pico remote allows for easy wireless control from anywhere in the home, and the ability to control multiple bulbs with a single switch adds convenience. Additionally, the switch can be installed in homes without a neutral wire, broadening its applicability to older homes.

Installation is straightforward, thanks to detailed instructions and supportive resources provided by Lutron. The kit includes a dimmer switch, a Pico remote, and a wall plate bracket, but note that the wall plate itself is sold separately. Another point to consider is that the smart hub, which enhances the system’s reliability and responsiveness, is also sold separately. The switch supports up to 150W dimmable LED bulbs or 600W incandescent/halogen bulbs, but it isn’t suitable for low voltage applications like track or landscape lighting.

Its sleek design and compact dimensions (1.13 x 2.93 x 4.69 inches) ensure it fits comfortably on most walls. However, those looking for a more integrated package might find the additional purchases necessary (wall plate and smart hub) to be a minor inconvenience. This kit is well-suited for anyone looking to upgrade their lighting system with a reliable, multi-functional smart switch.
