6 Best 4 Way Smart Switch 2025 in the United States

The Leviton Decora Smart Dimmer Switch is a versatile and modern addition to any home, offering extensive compatibility and a range of control options. It works seamlessly with popular voice assistants like Alexa, Google Assistant, and Apple Siri, allowing for convenient voice control. Additionally, it supports the Matter protocol, which can be enabled through a firmware update, making it future-proof for smart home integrations.

The switch is designed for easy installation, fitting into existing switch spaces and requiring a neutral wire. This makes it accessible for most standard home wiring setups. The device also offers flexible control options, including manual touch control, app control via the My Leviton app, and wire-free 3-way control using compatible companions. The dimmer functionality is robust, accommodating various bulb types and preventing flickering with fine-tuning settings. It’s rated for up to 300W dimmable LED or CFL and 600W incandescent or MLV, providing ample power for most lighting setups.

Users can personalize their lighting experience with customizable fade rates and preset light levels, creating the perfect ambiance for any occasion. However, it lacks built-in energy monitoring, which could be a downside for those looking to track their energy usage closely. Additionally, while the design is sleek and modern, it’s only available in white, which may not suit all decor styles. Despite these minor drawbacks, the Leviton Decora Smart Dimmer Switch is reliable and easy to use, making it a solid choice for anyone looking to upgrade their lighting controls.

The Lutron Caseta Smart Lighting Kit is a solid choice for anyone looking to upgrade their lighting system to a smart control setup. One of its standout features is compatibility with a wide range of smart home platforms, such as Amazon Alexa, Google Home, and Apple HomeKit. This makes it a flexible option for users who may already have other smart devices at home. The kit includes a smart hub, a dimmer switch, and a remote, allowing for convenient control of your lights from multiple sources, including voice commands and scheduled settings.

Installation is straightforward because the Caseta switch does not require a neutral wire, which is a common challenge with other smart switches. This means it works well in various homes, regardless of their age or wiring. Plus, the ability to set up a 3-way switch configuration without running new wires is a big plus for those who want to avoid complicated installations.

Design-wise, the switch has a clean and modern look, but it's not the most customizable choice if aesthetics are a top priority for your home decor. Moreover, while the hub operates independently of Wi-Fi, which enhances reliability, it also means that your smart features won't be able to integrate with the full capabilities of the internet if there is a system update or network issue.

The TP-Link Tapo S515 Smart Switch is a versatile option for those looking to control their lighting setup. It's compatible with single-pole, 3-way, and 4-way circuits, making it suitable for various settings, such as living rooms or hallways. The switch requires a neutral wire and 2.4GHz Wi-Fi for installation, which might be a slight hurdle if your home wiring doesn't meet these requirements. However, the app-guided installation process is user-friendly, even though consulting an electrician is recommended for those unfamiliar with electrical wiring.

The Tapo S515 is Matter-certified, ensuring compatibility with major smart home platforms like Alexa, Siri, Google Home, and SmartThings, which provides flexible and unified control. This makes it easy to integrate into an existing smart home setup and manage through voice commands or the app. One of its standout features is energy monitoring, allowing you to track and adjust energy usage to save on electricity bills. The switch also supports scheduling, which can help automate daily routines, and an Away Mode that randomly turns lights on and off to deter burglars.

In terms of design, the switch has a clean, modern look and is made with flame-retardant materials, adding an extra layer of safety. However, it lacks dimmer functionality, which might be a dealbreaker if you need that specific feature. While it ranks #96 in Electrical Light Switches, it may not be the top choice for everyone due to its requirement for neutral wiring and lack of dimmer capability. Nonetheless, for those who can meet the installation needs and do not require dimming, the Tapo S515 offers robust functionality and integration options.
