Turn any wired appliance into a smart, voice-controlled device.

The Tuya 16A Mini WiFi Smart Switch Module is a compact relay that hides behind your existing wall switch, ceiling rose, or appliance — giving you full wireless control without changing the look of your home. Connect it once to your WiFi, link it to the Tuya Smart or Smart Life app, and instantly control lights, fans, water heaters, pumps, or any 220V appliance from anywhere in the world.

Installation Note

Installation requires basic electrical knowledge — the module must be wired into your existing AC circuit. We recommend hiring a qualified electrician if you're not comfortable working with mains voltage. Always switch off power at the breaker before installation.
