    SONOFF DUAL R3 is a 2-channel Wi-Fi relay (15 A, 3300 W total) with energy metering and a motor mode for roller shutters, blinds and curtains. Installed in a wall box, it works with existing switches, eWeLink, Alexa and Google Assistant. Neutral wire required.

  • Product description

    Smart relay switch | 2-channel | 15A | 3300W | 100-240V | Wi-Fi | SONOFF | DUAL R3

    SONOFF DUAL R3 is a two-channel Wi-Fi relay with energy metering, installed in a wall box. It controls two separate lighting or appliance circuits, or one roller shutter, blind or curtain motor.

    Key idea:
    One device instead of two relays: two circuits or a shutter are controlled with existing switches, the app and voice, and consumption is visible in the app. A neutral (N) wire is required.
    Channels
    2 (or 1 motor)
    Load
    15 A / 3300 W total
    Connectivity
    Wi-Fi 2.4 GHz
    Dimensions
    54 × 49 × 24 mm

    How it works

    The relay is wired in the box: phase (L), neutral (N), two outputs (L1, L2) and two switch inputs (S1, S2). Each channel is controlled separately with an existing switch or push button.

    In motor mode, both outputs drive one bidirectional motor – up and down. After calibration, the shutter or curtain position can be set in percent in the app.

    Built-in metering shows power, voltage, current and consumed energy, so you can see how much electricity each circuit uses.

    Why choose DUAL R3?
    Two channels, motor mode and energy metering in one compact housing save space in the box, reduce the number of devices and allow shutters to be controlled without a separate module.

    Main functions

    • Two independent channels – two circuits are controlled separately by switch, app or voice.
    • Motor mode – roller shutters, blinds, awnings and curtains – up, down, stop and position in percent.
    • Energy metering – power, current, voltage and consumption history in the app.
    • Works with existing switches – S1 and S2 inputs accept latching switches and push buttons.
    • Timers and scenes – circuits and shutters are controlled by time, sunset or sensors.
    • Voice control – Amazon Alexa and Google Assistant commands.

    Where is it used?

    • Two lighting groups in one room
    • Roller shutters and blinds
    • Curtain and awning motors
    • Light and fan in a bathroom
    • Office and commercial lighting
    • Upgrading old installations without new wiring

    Use by need

    For homeowners.
    Shutters or two light groups are controlled by phone and schedule, and consumption is visible in the app.
    For electricians.
    One module instead of two relays and a separate shutter controller – fewer wires and less space in the box.
    For smart home integrators.
    Motor mode with position in percent and energy data suit scenes and automations.

    Practical use

    If the living room has an electric roller shutter with a double push button, DUAL R3 is installed in the box behind the button, switched to motor mode and calibrated – the shutter lowers at sunset, and the button works as before.

    Pros

    • Two channels in one housing
    • Motor mode for shutters and curtains
    • Built-in energy metering
    • Works with existing switches and push buttons
    • Fits in a wall box
    • Alexa and Google Assistant support

    Cons / limitations

    • Neutral (N) wire required
    • 2.4 GHz Wi-Fi only
    • Total load limited to 15 A
    • Motor mode – only one motor up to 1 A

    Safety and installation notes

    • Switch off the circuit breaker and check for voltage before installation
    • Installation must be done by a qualified electrician
    • Do not exceed 15 A total and 10 A per channel
    • In motor mode connect only one motor not exceeding 1 A
    • Do not install in damp locations or outdoors without a suitable enclosure

    Quick selection guide

    2 channels
    15 A / 3300 W total
    Motor mode
    Energy metering
    Wi-Fi 2.4 GHz
    Neutral required
    Suitable when you need:
    • control two lighting circuits from one box
    • automate roller shutters, blinds or curtains
    • see the electricity consumption of circuits
    Check before use:
    • whether there is an N wire in the box
    • the load on each channel
    • the shutter motor current (up to 1 A)
    • the 2.4 GHz Wi-Fi signal at the installation point
    Important reminder: DUAL R3 is not a protective device – the circuit must have a circuit breaker, and an RCD in damp locations.

    FAQ

    Can it control roller shutters?
    Yes, in motor mode both channels drive one bidirectional motor, and the position can be set in percent.
    Is a neutral wire needed?
    Yes, DUAL R3 is powered from L and N.
    Does it measure consumption?
    Yes, the app shows power, current, voltage and energy.
    What is the maximum load?
    15 A and 3300 W for both channels together, up to 10 A and 2200 W per channel.
    Will existing switches work?
    Yes, latching switches or push buttons are connected to S1 and S2.
    How does it differ from DualR3 Lite?
    DualR3 Lite has no energy metering; the other main functions are similar.
