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 TP-Link Tapo Matter Smart Dimmer Switch is a strong choice if you're looking to upgrade your home lighting with Alexa and other smart assistants. It requires neutral wiring and a 2.4 GHz WiFi connection, which is common in many homes, but you’ll want to check your wiring setup before buying. Installation is straightforward, especially if you follow your old switch's wiring, making it suitable for most single-pole setups. The dimming feature covers the full range from 0 to 100%, letting you easily adjust brightness to create the perfect atmosphere.

Its Matter certification means it works smoothly across major platforms like Alexa, Siri, Google Home, and Samsung SmartThings, which is handy if you use multiple devices or brands. You get remote control via the Tapo app and voice commands, plus the ability to schedule lights and use fade on/off for gentle light transitions—great for comfort. The Away Mode can help enhance security by simulating occupancy. Design-wise, the switch has a matte finish and a clean look that fits most interiors.

A limitation to note is that it only supports 2.4 GHz WiFi, so you can’t use it with 5 GHz networks, and it requires neutral wiring, which some older homes may lack. Also, the switches are single-pole only, so if you have multi-way setups, this model won’t cover those. Packed as a 4-pack, it offers good value if you want to outfit several rooms at once. For those seeking easy, flexible smart lighting that integrates well with popular voice assistants and standard home networks, this switch is a suitable option.
