SONOFF 4CH Pro R3 4-Channel Wi-Fi Smart Switch with RF Control

Description

The SONOFF 4CH Pro R3 is a powerful 4-channel Wi-Fi smart switch designed to control multiple electrical devices independently or simultaneously. With four relay channels, the device allows you to automate lights, appliances, gates, garage doors, irrigation systems, and other electrical equipment from a single smart controller.

By connecting the switch to your 2.4 GHz Wi-Fi network, you can remotely control connected devices using the eWeLink mobile app from anywhere in the world. The switch supports RF 433 MHz remote control, allowing compatible RF remotes such as the RM433 to operate the device even when Wi-Fi is unavailable.

The 4CH Pro R3 features three configurable working modes that can be set directly in the eWeLink app:

• Self-locking mode – Each channel operates independently, ideal for controlling multiple lights or appliances.

• Interlock mode – Only one channel can be active at a time, perfect for motor direction control such as blinds or roller shutters.

• Inching mode – The relay automatically turns off after a preset time (0.5–3600 seconds), useful for garage doors or gate triggers.

The device also supports automation scenes, scheduling timers, and device sharing, allowing multiple users to control the system. With voice assistant compatibility, you can operate connected devices hands-free using Amazon Alexa or Google Assistant.

Built with a durable flame-retardant enclosure and designed for flexible installations, the SONOFF 4CH Pro R3 is ideal for home automation, commercial control systems, and smart building projects.
