Sonoff Dual R3

The Sonoff Dual R3 is a flush-mounted Wi-Fi smart dual relay switch module designed to transform traditional switches and outlets into smart, remotely controllable devices with power monitoring capabilities.

Key Features:

• Dual Relay Control: The module has two independent channels, allowing users to control two different lights or appliances simultaneously via the eWeLink app, voice commands, or existing wall switches.
• Power Monitoring: The standard Dual R3 (not the Lite version) includes a built-in power metering function that provides real-time monitoring of voltage, current, and power consumption for each connected channel, helping to track and manage energy usage efficiently.
• Multiple Working Modes: It supports three distinct operation modes:
  • Switch Mode: For basic ON/OFF control of lights and other appliances.
  • Motor Mode: Specifically for automating motorized appliances like roller shutters, window shades, blinds, and awnings, allowing for app control and scheduled events.
  • Meter Mode: In this mode, the connected load remains constantly on, and the device functions solely for power tracking and metering.
• Control & Compatibility:
  • Remote Control: Manage devices remotely via the eWeLink app on Android and iOS devices.
  • Voice Control: Compatible with Amazon Alexa, Google Assistant, and supports Siri shortcuts.
  • External Switch Support: Works with various external switch types (momentary, rocker, ON/OFF) to retain manual control.
• Safety & Reliability: Features TUV certification, overload protection, and is made with fire-retardant PC V0 material for safe operation.
• Installation: The compact design is suitable for flush-mounting behind standard wall switches, requiring a neutral wire for installation.
