Sonoff Dual is a WiFi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 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 WiFi access, remote control through APP EweLink.

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 WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi 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.

Works With Amazon Alexa

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".

Sonoff Pow is a 16A WiFi smart light switch that allows you to remotely manage and control your appliances and monitor your home energy usage. The WiFi light switch works like a power monitor, which allows you to keep track of 99% accurate real-time current, voltage and power on your app.

The power switch can protect your appliances from overload. What you need to do is to set threshold values for the current, voltage and power. It works like a kwh calculator that can measure electricity consumption for a specified period and a day. The eWeLink app provides 100 days recorded electricity usage data, which you can export to your phone storage. You can keep track of how much energy your appliances are consuming and estimate your running costs.

With the Pow R2 power monitoring switch, you can spend less on your electricity bill. The timers schedule your appliances automatically power on and off at a defined time. The scene lets your appliances work together in new ways, like setting the heater auto-off when the door light is off.

Features

• Remote turn on/off connected appliance via APP EWeLink
• Keep track of live current, voltage and power
• Set threshold values to protect your devices from overload
• Check power consumption over a specified period
• View and export 100 days recorded power usage data
• View real-time device status on EWeLink
