Tuya 634844 Mini WiFi Smart Switch Relay Module: Remote control via app
This smart switch is for the homeowner who wants to simplify daily routines, like turning off forgotten lights from bed or scheduling a lamp to deter intruders. While it handles home security, its real value is in saving you time and effort—no more walking across the house to flip a switch.
Set a timer for your porch light to turn on at dusk, and it happens reliably every day. The two-way relay lets you control two circuits independently, perfect for a fan and light combo. With Alexa compatible voice control, just say the command and it responds instantly. The app sends a notification if the switch loses power, so you know immediately. It works seamlessly with Smart Life and Tuya Smart apps, making automation straightforward for any user.
