Dual relay channels with independent control 100–240V AC input with 15A total load capacity Real-time power metering: voltage, current, and energy Switch Mode, Motor Mode, and Metering Mode support 2.4GHz Wi-Fi connectivity with app control and automation Max. load: 10A/Gang – 15A/Total
The SONOFF DUALR3 Dual Relay Two Way Power Metering Smart Switch SONOFF DUALR3 overview for smart dual-channel control is a Wi-Fi enabled in-wall relay module designed to automate and monitor two independent electrical circuits. It installs behind a wall switch and adds app control, scheduling, and energy tracking. Therefore, it is suitable for lighting, appliances, and motorized systems like blinds and curtains.
The electrical performance and load handling support a 100–240V AC input with a maximum total load of 15A (3300W). Each channel supports up to 10A (2200W). In addition, it uses two independent relay outputs for flexible control. As a result, it can manage two devices or circuits separately.
The energy monitoring and measurement system tracks voltage, current, power, and energy consumption in real time. Moreover, data is available per channel for detailed usage analysis. Therefore, users can monitor electricity consumption and optimize energy use.
The operating modes and installation flexibility include Switch Mode, Motor Mode, and Metering Mode. In addition, it supports two-way switch wiring and requires a neutral wire. Therefore, it integrates into both new and existing electrical setups using standard 2.4GHz Wi-Fi.
