Sonoff 4CH PRO R3 4-Channel Smart Switch WiFi 2.4GHz 10A

Description

The Sonoff 4CH PRO R3 is a professional-grade, multi-channel smart switch designed for integrating advanced automation into residential and light commercial environments. It operates on 100-240V AC and communicates via robust 2.4GHz WiFi (802.11 b/g/n) with WPA/WPA2 security, ensuring reliable connectivity for remote management through the eWeLink platform. A key upgrade from previous models is the inclusion of an integrated 433MHz RF receiver, allowing for additional control via compatible wireless remotes.

This unit distinguishes itself with software-configurable operational modes—Self-Locking, Interlock, and Inching—which are set directly within the eWeLink app instead of via physical hardware jumpers. This flexibility allows a single device to manage diverse loads, from simple on/off lighting control to timed motor operations for blinds or gates. Its DIN-rail mountable design and compact form factor make it ideal for centralized installation in distribution boards, enabling the smart control of devices located away from traditional wall switches.
