Smart Switch 3Gang Smart Light Switch 3 Gang - WiFi 2.4 GHz

In this review of the Smart Switch 3Gang by Lesim, the bottom line is simple: this is a good choice for homeowners who want a clean, three-gang in-wall smart switch that works with voice assistants and app schedules. The package includes three separate switches and a single 3-gang wall plate, and the tempered glass touch panel with blue LED backlight gives a modern look. It requires a neutral wire and only works on a 2.4 GHz Wi-Fi network, so it is best for installations that meet those electrical and network constraints.

Key Features

• Three separate switches: The kit includes three individual switches and one 3-gang wall plate so multiple circuits can be controlled independently without buying extra hardware.
• Touch control and LED backlight: Tempered glass touch surface with a 40 ms touch response and a subtle blue indicator makes on/off status easy to see in the dark without disturbing sleep.
• Voice assistant compatibility: Integrates with popular voice assistants for hands-free on and off commands, simplifying routine lighting control.
• App schedules and scenes: Use the Smart Life app to create schedules, timers and scenes so lights can turn on at sunset or follow custom routines automatically.
• Group control and sharing: Devices can be grouped in the app and shared with family members so multiple users can control the same switches from their phones.

Who It's For

This product is aimed at DIY homeowners and renters with standard single-pole lighting circuits who have an available neutral wire in the switch box and a stable 2.4 GHz Wi-Fi network. It suits people who value a sleek, glass touch panel and want to combine manual touch control with app and voice automation.

It is less suitable for those without a neutral conductor, for multiway (3-way or 4-way) switching setups, or for households that rely exclusively on a 5 GHz-only Wi-Fi network. Installers who need advanced commercial features or professional-grade lifespan guarantees may want to consider higher-end alternatives.

Pros & Cons

Pros

• Easy installation for single-pole circuits and a polished, modern look thanks to the tempered glass plate.
• Responsive touch control and a low-power LED indicator that is visible in darkness without being disruptive.
• Smart features such as voice control, scheduling, grouping and device sharing add everyday convenience.

Cons

• Requires a neutral wire and only supports 2.4 GHz Wi-Fi, which limits compatibility in some homes.
• Some users report intermittent Wi-Fi connectivity issues, so reliability may vary with network environment.
