## Long description

The Sonoff Dual R3 Wired & Wireless is a dual-relay Wi‑Fi smart switch with built‑in power metering, designed for controlling lights, appliances and motorized devices. It supports 100–240V AC input and both wired and wireless control, fitting standard in‑wall installations or DIN‑rail mounting with a detachable base. The unit is CE and RoHS certified and includes safety features and environmental resistance validated by tests.
Advantages
Dual independent relay channels provide separate control and power monitoring for two loads while supporting three working modes including a dedicated meter mode that keeps relays closed for continuous measurement. The module is TUV‑certified for higher reliability, offers two‑way control with existing wall switches, remote control via Wi‑Fi, scheduling for automated open/close of motorized curtains and blinds, and compatibility with voice assistants via eWeLink shortcuts. Multiple built‑in protections include overload cut‑off and resistance to heat, humidity and mechanical impacts.
Suitable for
Controlling motorized curtains, blinds, roller shutters and awnings (tubular motors, 100–240V AC)
Smart control of lights and household appliances with two independent channels
Energy monitoring and historical power consumption tracking
In‑wall installations and DIN‑rail mounting in distribution boxes
Key specifications
Working voltage: 100–240V AC, 50/60Hz
Device size: 54 × 49 × 24 mm
Two independent relay channels with power metering
Working modes: switch modes and meter mode (relays fixed ON for metering)
Connectivity: Wi‑Fi (controlled via eWeLink), supports wired & wireless control
Certifications: CE, RoHS, TUV tested for safety and environmental resistance
How to use
Install the Dual R3 into an in‑wall box or mount it on a DIN‑rail using the detachable base, and wire the device according to the motor or load wiring diagram supplied by the manufacturer. Add the device to the eWeLink app over your Wi‑Fi network to configure channels, set schedules and enable voice assistant shortcuts. For motorized curtains, connect the motor to the two channels and configure open/close schedules or percentage positions in the app. Use the meter mode when continuous power monitoring is required; in this mode relays remain on and control via app or external switches is disabled.
Usage recommendations
Follow local electrical codes and turn off mains power before installation. Ensure connected motors and appliances match the switch’s rated AC voltage and current limits. Use the overload protection settings in the app to define safe voltage, current and power thresholds. For voice control, configure Siri shortcuts or link to Amazon Alexa / Google Assistant through the eWeLink app as described in the manual.
