Sonoff Dual is a Wi-Fi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means that 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick Wi-Fi access, remote control through  eWeLink App.

In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang Wi-Fi light switch is not an ON/OFF toggle switch, it is only a Wi-Fi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.

You can ask Alexa to turn on/off Sonoff Dual.

Standard voice control commands phrases for Sonoff Dual (if you just say the device name, Alexa will turn on/off all the 2 gangs immediately):

Alexa, turn on {deviceName}
Alexa, turn off {deviceName}

Alexa, turn on {deviceName} {gangName}
Alexa, turn off {deviceName} {gangName}

Explanation: if the device name of your Sonoff Dual is "My Switch", the gang name is "Gang 1", then you can control with "Alexa, turn on My Switch Gang 1".
