Frequently Asked Questions

Q: Does the WiFi Smart Light Switch Module require a hub?

A: The WiFi + RF433 variants connect directly to your 2.4GHz home WiFi network — no hub is needed. However, the Zigbee 3.0 + RF433 variants require a Tuya Zigbee hub for operation, which provides a more stable mesh-network connection throughout your home.

A: This smart light switch module is compatible with Amazon Alexa and Google Home for voice control, and is managed via the Smart Life or Tuya app on both iOS and Android devices. It supports 2.4GHz WiFi networks only.

Q: Can I still use my existing physical wall switch after installing this module?

A: The module is available in 1-gang, 2-gang, and 3-gang configurations across WiFi + RF433, Zigbee 3.0 + RF433, and wireless switch variants, giving you flexibility for single or multi-circuit control.
