The SONOFF DUALR3 Series Smart Wi-Fi Dual Relay Switch is a compact, flush-mounted module designed to upgrade standard wall switches and appliances into intelligent, remotely controlled devices. Installed behind traditional switches, it seamlessly integrates into smart home systems, allowing wireless control through the eWeLink app, voice assistants, and automation scenes.

Available in two variants, the DUALR3 series provides flexible options depending on user needs:

• DUALR3: Includes full power monitoring to measure and analyze the energy consumption of connected devices.
• DUALR3 Lite: Provides the same dual relay smart control but without the energy monitoring feature, making it a cost-effective option for applications where power tracking is not required.

Key Features (Both Versions):

• Three Working Modes: Switch mode, motor mode, and (for DUALR3 only) meter mode.
• Dual Two-Way Control: Independently control two appliances or lights from multiple locations.
• Motorized Device Control: Supports roller shutters, blinds, curtains, awnings, and other tubular motor systems.
• Hands-Free Voice Control: Works with Alexa, Google Home, and Siri shortcuts.
• Smart Scheduling & Scenes: Automate tasks with timers, schedules, and integration with other SONOFF devices.
• Compact & Safe Design: TÜV-certified with built-in protection against overheating and fire risks.
