SONOFF DUALR3 Lite Dual Relay Two Way Smart Switch – 2-Gang Wi-Fi Relay Module, Motor Control, eWeLink App, Alexa & Google Assistant Compatible
Overview:
• The SONOFF DUALR3 Lite is a 2-Gang Wi-Fi Smart Dual Relay Switch Module designed to control two independent electrical circuits or one two-way motorized device such as curtains, blinds, shutters, or awnings.
• It is a flush-mounted smart relay module that can be installed behind a standard wall switch to convert traditional switches into smart switches.
• The module supports remote control through the eWeLink App, allowing users to turn devices ON/OFF, set schedules, use timers, and create automation scenes.
• It supports Switch Mode for lighting/appliance control and Motor Mode for compatible 100–240V AC motorized systems.
• The DUALR3 Lite is the Lite version of DUALR3 and is mainly used for smart relay and motor control; it does not include full power metering features like the standard DUALR3 version.
