The Sonoff DUALR3 is a 2-gang Wi-Fi smart switch designed to give you independent control over two different electrical circuits from a single compact device. It integrates easily into your home via the eWeLink app and supports voice commands through Amazon Alexa and Google Assistant, allowing you to manage your lighting or appliances without needing to be physically present. Built with a flame-retardant PC housing, this switch measures 54 x 49 x 24 mm, making it small enough to fit into most standard electrical boxes. It handles a maximum load of 10A per channel, totaling 15A across both, with a power capacity of up to 2200W per gang. To ensure safety during operation, the device includes built-in protections against overloading, overheating, and short-circuits, and it carries TÜV, CE, FCC, and RoHS certifications. One of its most practical features is the real-time power metering for each channel, which helps you keep track of energy consumption for the connected devices. For installation, the unit requires a neutral wire and is versatile enough to work with various wall switch types, including rocker, momentary, and SPDT options, ensuring it fits into your existing home wiring setup.
