Who it fits
Good fit for
You should choose this switch if you need to control lights from two locations, such as stairs or hallways. It fits homes that already have a neutral wire in the switch box. Users who want to automate lighting schedules or share control with family members will appreciate the app features. It is ideal for standard incandescent or LED bulbs that are dimmable, provided you stick to 2.4GHz networks.
Who should skip it
Skip this option if your switch box lacks a neutral wire, as it is strictly required for operation. Do not buy this if you rely on Apple HomeKit, as the device only works with Alexa and Google Assistant. It is also unsuitable for motorized devices, fans, or smart lights that use Bluetooth or Wi-Fi directly. If you need 5GHz WiFi support, this 2.4GHz-only model will not connect to your network.
Verdict: This two-pack offers solid 3-way functionality and reliable dimming for compatible bulbs. It is a practical choice for users with neutral wires who need multi-location control without a hub.
Key specs for TREATLIFE dimmers
Circuit Type: Single-Pole, 3-Way
This switch works in both standard single-pole setups and 3-way configurations. You can control lights from two different locations, such as the top and bottom of a staircase. This flexibility allows you to replace traditional 3-way switches without rewiring the entire circuit. It suits homes with multi-location lighting needs.
Connectivity: 2.4GHz WiFi
The device connects directly to your home network using 2.4GHz WiFi signals. It does not support 5GHz bands, so ensure your router broadcasts on the correct frequency. This direct connection eliminates the need for additional hardware. It offers reliable remote access for controlling lights from anywhere using your smartphone.
Hub Requirement: No Hub Required
You do not need to purchase a separate smart home hub or bridge to operate this switch. It connects straight to your WiFi network. This simplifies setup and reduces clutter. It is ideal for users who want a straightforward installation without managing multiple smart home devices or additional gateways.
Smart Home Compatibility: Alexa, Google Assistant
This dimmer integrates with Amazon Alexa and Google Assistant for voice control. You can adjust brightness or turn lights on and off using voice commands. It does not support Apple HomeKit. This compatibility suits users already invested in the Amazon or Google smart home ecosystems for convenient hands-free operation.
Wiring Requirement: Neutral Wire Needed
Installation requires a neutral wire in your wall box. If your existing switch lacks this wire, you may need an electrician to update the wiring. This requirement ensures stable power for the smart components. Check your current setup before purchasing to avoid compatibility issues during installation.
Design and Build Details
According to the listing, the TREATLIFE 3-Way Smart Dimmer Switch 2-Pack features a white finish. The faceplate measures 4.84 inches in width, 3.3 inches in length, and 1.57 inches in height. These dimensions align with standard US electrical box sizes. You can mount this device in most common wall boxes without needing special adapters or deep boxes. The compact profile ensures it sits flush against your wall.
The listing notes the use of flame-retardant materials. This design choice prioritizes safety during operation. Built-in overheat protection is also included, which adds a layer of reliability for continuous dimming use. FCC certification confirms the device meets specific electromagnetic interference standards. This helps ensure your WiFi connection remains stable alongside other home electronics.
The layout supports a neutral wire requirement. You must verify your existing wiring includes a neutral conductor before installation. The switches are designed for dimmable bulbs only. They do not support motorized devices, transformers, or fans. This restriction means you should check your light fixtures carefully. The physical controls allow manual dimming and switching. The white color blends with most interior decor styles, keeping the focus on your lighting rather than the hardware itself.
Setup and Daily Use Guide

You cannot connect this device to a 5GHz network. The switch does not require a separate hub for operation. It pairs directly with your home router via WiFi.
For a 3-way setup, you must install the smart dimmer on the power source side. The other end connects to a standard, non-smart 3-way switch. This configuration allows you to control the light from two locations. You can also use the device as a single-pole switch in other circuits.
Daily use relies on the Smart Life or Treatlife app. You can adjust brightness from 1% to 100% remotely. The app supports scheduling features like countdown timers and sunrise or sunset routines. A brightness memory function recalls your last setting after a power outage. This helps maintain your preferred lighting level automatically.
Voice control works through Alexa and Google Assistant. You can issue commands to change brightness or turn lights on and off. The device does not support Apple HomeKit. You can share control with family members through the app. This allows multiple users to adjust settings for different occasions.
