Frequently Asked Questions

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

A: No — the WiFi version connects directly to your 2.4GHz home WiFi network and requires no additional hub or gateway. The Zigbee 3.0 version, however, does require a compatible Zigbee gateway (sold separately) to function.

Q: Is this smart switch module compatible with Amazon Alexa and Google Home?

A: Yes! The module is fully compatible with Amazon Alexa, Google Home, Tmall Genie, and Home Assistant via the Tuya Smart Life app. Once connected, you can control your devices using simple voice commands.

Q: Can I install this module in a 2-way (dual-control) switch setup?

A: Absolutely. The module supports three wiring configurations: direct device connection (no physical switch), single-pole (1-way) switch, and dual-control (2-way) switch. It can be installed inside a standard switch box without affecting your existing switch functionality.

Q: What happens to the module's state after a power outage?

A: The module features built-in state memory. You can configure it to restore to ON, OFF, or its last state before the outage — so your devices behave exactly as you expect when power returns.
