10 Best Smart Light Switches 2025 in the United States

The Leviton Decora Smart Dimmer Switch is designed for homeowners who want flexible and smart control over their lighting. It requires a neutral wire for installation, which is common in many modern homes but could be a limitation for older wiring setups. This switch supports a wide range of control options, including app control via the My Leviton app, voice commands through Alexa, Google Assistant, and Apple Siri, and even works with the emerging Matter smart home standard after a firmware update. It’s versatile in installation, functioning either as a single-pole or 3-way switch, and supports wired or wireless companion switches for multi-location control without extra wiring. The dimming capability is strong, tailored for compatible LED, CFL, incandescent, and magnetic low voltage bulbs, with customizable settings to prevent flickering and adjust brightness levels smoothly.

Installation is designed to be straightforward with wire leads and a slim form factor, and the setup process is guided by the app, which helps users get started quickly without needing a central hub. A notable downside is the absence of explicit energy monitoring features, which some smart switches offer to track power usage. If tracking energy consumption is a priority, this switch might not meet that need. However, it does provide remote control so you can easily check and adjust lighting from anywhere, indirectly helping save energy by ensuring lights aren’t left on unnecessarily. This switch suits users looking for dependable smart dimming with broad voice and app control, easy installation with a neutral wire, and flexibility to expand control options in multi-switch setups, while it is less ideal for those wanting built-in energy monitoring or who lack a neutral wire in their home wiring.

The Leviton Decora Smart Switch is a versatile and well-connected option for anyone looking to upgrade their home lighting to a smart system. It requires a neutral wire, which is common in newer homes but might be a limitation in some older electrical setups. This switch supports popular voice assistants like Alexa, Google Assistant, and Apple Siri, making hands-free control easy and convenient. Thanks to its Matter compatibility, future-proofing your smart home is simpler, as it can work seamlessly with other devices after a firmware update.

Installation is straightforward with its slim design and wire leads, and the My Leviton app guides you through setup without needing an extra hub, connecting directly to 2.4 GHz Wi-Fi. The switch supports both single-pole and 3-way configurations, allowing control from multiple locations with compatible companion switches, which adds flexibility for larger rooms or hallways. It can handle up to 15 amps, so it’s suitable not just for lights but also ceiling fans and small motors. Features like scheduling, random on/off for security, and auto-shutoff help save energy and provide peace of mind.

This switch is well suited for users who want a reliable, easy-to-install smart switch with strong voice assistant support and flexible control options, especially if your home wiring supports a neutral wire.

The Lutron Caseta Original Smart Dimmer 3-Way Switch Kit offers a versatile solution for controlling your lights with various options. Compatibility is a strong point, as it connects with leading smart home devices like Alexa, Google Home, and Apple HomeKit, though a smart hub is required for this functionality (sold separately).

The control options are extensive—you can use the Lutron app, voice commands, or the included Pico remote to manage the lights, and even create schedules or lighting scenes (hub required for some features). The dimming capability supports up to 150W dimmable LED bulbs or 600W incandescent/halogen bulbs, but it's not suitable for low voltage applications such as track or landscape lighting.

Installation is straightforward and can be completed in about 15 minutes, with helpful resources and 24/7 technical support available. Notably, the switch works in any home without requiring a neutral wire, making it accessible for older buildings. Connectivity is reliable, especially with the smart hub, which ensures the system operates even if Wi-Fi goes down. The wallplate is not included and must be purchased separately, which could be an inconvenience. This product is ideal for users seeking a comprehensive and easy-to-install smart lighting solution that offers robust compatibility and flexible control options.
