SONOFF POWR2 is a 15A WiFi smart lighting switch that allows you to remotely manage and control your appliances and monitor home energy consumption. The WiFi switch works as a power monitor, allowing you to track 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 set the threshold values for current, voltage and power. It works as a kwh calculator that can measure the electricity consumption for a given period and a day.
The eWeLink app provides recorded electricity usage data for 100 days, which you can export to the phone memory. You can track how much energy your appliances are consuming and estimate your running costs.
With the POWR2 power monitoring switch, you can spend less on your electricity bill. The timers schedule automatic switching on and off of devices at a defined time.
The scene allows your appliances to work together in new ways, such as setting the heater to turn off automatically when the door light is off.
Note - The router must be a 2.4GHz device (5.0GHz WLAN is not supported), but there is no limitation for the smartphone network (2G/3G/4G/Wi-Fi are all compatible).
