Tuya cb3s WiFi Bluetooth Relay Module with Remote Control: Wi-Fi and Bluetooth LE connectivity
This Tuya smart relay module is for the DIY homeowner who wants to upgrade a single light or appliance without rewiring. Think of it as your tool for adding voice control to that old lamp in the living room or scheduling the porch light to turn on at dusk.
While many smart home products focus on security, this module offers convenience and energy savings. It lets you create a connected home on your terms. The Smart Life app gives you remote control from anywhere, and setup is straightforward—connect the wires, sync via Wi-Fi, and you're managing devices with your phone or voice through Amazon Alexa or Google Assistant. You will appreciate how the motion sensor option in some models triggers lights before you fumble for a switch, making daily routines smoother.
With features like timer functions and group control, it helps reduce energy waste by automating usage. Install it in a standard junction box for a clean look, and enjoy reliable performance with a 1-year warranty. This module makes smart home technology accessible and practical for everyday life.
