Wifi Remote Switch with Power Consumption Measurement AC 85 - 250V 16A MAX  (3500W) Sonoff

Overview

Sonoff Pow is a wireless switch which connects to electronic devices such as home appliances via WiFi. The electronic devices can be controlled by the mobile application eWeLink which can be run using WiFi, 2G, 3G or 4G network. 
Sonoff Pow has the amazing capability to display the electronic device’s instant wattage consumption. It also has the option to report the energy consumption in kWh over a period of time, and thus generate power consumption reports over a certain time interval, such as a month. Sonoff Pow, therefore, allows you to figure out which appliances in your home consume the most power so you can cut down your electricity bill. 
Since Sonoff Pow belongs to the Sonoff family, it has all the functions of a basic Sonoff. Through the mobile application eWeLink, remote home control becomes a reality. Consumers can remotely control the operation of home appliances by turning them on, off instantly or according to a user specified schedule, such as repeat or countdown. Consumers can also share the remote access with others for a mutual control of the appliances.  
Apart from traditional consumers, Sonoff Pow is a very exciting product for those into hacking, since four program ports have been reserved for burning external firmware. Now, isn’t that thrilling?
