This 4-channel Wi-Fi smart switch lets you control lights, pumps, or routers from your phone or voice. Use it to turn off a forgotten garage light or schedule your porch lamp for dusk. It works with Alexa and Google Home for hands-free operation.
Unlike basic switches, this module offers three working modes: self-locking (standard on/off), interlocking (one circuit on, others off), and inching (momentary trigger). This flexibility is ideal for applications like motor control or gate openers. The RF 433MHz remote adds a physical control option, so you can turn devices on/off without pulling out your phone.
Installation is straightforward with clear wiring diagrams, and the compact 75x73x17mm module fits behind existing wall plates. Share access with family through the Tuya app so everyone can control the schedule or turn things off from anywhere.
