Model MINIW1 Ultra Mini WiFi Light Switch Module Compact size and wide compatibility Ultra mini body measures 41 x 41 x 22 mm, compatible with about 95 percent of standard switch installation boxes. Small form factor lets you install the module inside a wall switch box or on a lamp housing for spacesaving retrofits. Note: turn off electricity during installation. Remote control and voice operation Control lights and circuits from anywhere using a Tuyacompatible smart app such as Smart Life on your phone or tablet. Hands voice control works with Alexa, Google Home, and Yandex Alice for convenient spoken commands. Smart scheduling and automation Set timers, schedules, and countdowns to automate lighting for daily routines and energy management. Link the module with other smart modules, sensors, and appliances to create scenes such as sleeping mode, dinner mode, or arrival mode. Flexible control and wiring support Dual way control enables upgrading twoway switches without changing existing house wiring. Three switch types available: rocker flip, synchronous state change, and selfreset switch for different wall button behaviors. Status memory lets you choose how the module responds after a power loss: restore on, restore off, or retain the previous state. Interlock function ensures only one channel is on at a time, useful for mutually exclusive loads. Groupcontrol allows multiple switches in different rooms to be controlled together. Family share supports limited user access so household members can control the system.
