The SONOFF 4CHPROR3 4-Gang Wi-Fi Smart Switch W/ RF Control is a sophisticated device designed to enhance smart home capabilities by allowing control over lights and appliances in four distinct areas. This switch integrates Wi-Fi and RF control, enabling users to manage connected devices via the RM433 remote controller. It supports independent or mutual control of four devices, offering flexibility in operation modes such as self-locking, interlock, and inching. The dry contact feature allows the switch to control the line without powering the device directly. Additionally, the switch can be operated using a common 433MHz remote control, providing functionality even without internet access. It is designed for easy installation on a guide rail, facilitating control of devices that are not easily accessible.
