Description
The SONOFF DUALR3 / DUALR3 Lite is a dual-channel Wi-Fi smart switch module for flexible home automation. In Switch Mode it controls two appliances independently – lights, ceiling fans, coffee makers and more – and in Motor Mode it turns motorized curtains, blinds and roller shades into smart devices you can control by app, voice or automation.
The DUALR3 also measures voltage, current and power on each channel to help you track and optimize energy use, while the DUALR3 Lite offers the same switching and motor control without power metering. Both support 6 types of external wall switches (rocker, momentary, SPDT and more), so you keep manual control from your existing switches.
Note: choose DUALR3 or DUALR3 Lite from the options. Maximum load 15A total (10A per channel); motor load 10–240W / 1A max. Installation must be done by a qualified electrician.
