Teckin SR42 Smart Wi-Fi Light Switch (Only for 3-way)

【Peace of Mind】Teckin Smart Light Switch with home automation options (turn on and off the light on the smartphone) provide you a home security system when you're not there, helping you to travel stress-free. Create schedules (timer or countdown) to automatically turn on and off the light based on everyday routines or to simulate occupancy while you are on vacation to trick potential intruders.
【Remote Control】Remote control lights from anywhere and anytime using your smartphone via Smart Life, whether you are in your cozy bed, in the office, or on vacation. You can turn on lights no matter where you are before arriving home or after leaving for your comfort.
【Voice-activated Lighting】The Smart Light Switch works directly with Amazon Alexa and Google Assistant to manage your devices through Voice Control. Assign a name to each Smart Plug and communicate each plug by name when making a voice command. Simple voice control makes your hands free when you are coming through the kitchen door with your hand full of groceries, sleeping in your cozy bed, holding your baby, etc.
【Schedule and Timer Create 】Custom schedules and automatically turn lights on/off at a specific time. You can set time as you want when you're arriving home, after living or sleeping, convenient without your fingertips. Scheduling also helps lower your electricity bill by keeping power-hungry devices off when they are not needed.
