20A Wi-Fi & RF Smart Switch Module

Product Description

Want smart control for heavier appliances without changing your switch?

Need to turn things on or off from your phone?

Install this compact 20A module behind your existing switch to add phone, voice, and schedule control to lights, fans, and suitable high-power devices.

Your current switch still works, while the connected appliance gains smart control.

Top Highlights

• Control heavier appliances from your phone: Turn suitable lights, fans, or other devices on and off through the Tuya or Smart Life app from anywhere.
• Set it and forget it: Create schedules and timers so the appliance turns on or off at the times that suit you.
• Share control with the family: Give everyone in the house access so they can manage the device from their own phones.
• Create simple routines: Build scenes that turn the connected device on or off together with other supported products.
• Make it respond automatically: Link it with supported motion, door, or other sensors so the device can turn on or off based on what happens at home.
• Use your voice when your hands are full: Ask Alexa or Google Assistant to turn the connected device on or off.
• Keep your existing switch: The module hides behind your current switch so the wall looks the same.
• Add RF remote control: Supports a compatible 433 MHz remote (sold separately).
