Sonoff POW R2

Sonoff Pow R2 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 aut0-off when the door light is off. See the manufacture’s website

One of the great benefits with the Sonoff devices is that they the schematic is published by the manufacturer (here) and this has allowed the “hacker” community to implement features that are not offered by the standard firmware. We have a number of projects planned for these versatile devices so please drop by an check what we are up to.

If you want to go beyond the standard Sonoff functionality and develop functions other than the simple on off control then consider replacing the factory firmware with some custom firmware. Visit the following tutorial https://randomnerdtutorials.com/how-to-flash-a-custom-firmware-to-sonoff/ and look at the following firmware projects:

Inventech is a solution development company and we often use commercially available hardware and adapt or customize it to a particular problem. This methodology has been successfully applied to a number of our projects and products. If your requirement extended beyond just simply switching off an electrical appliance, perhaps you want to provide a dashboard, or monitor an environmental variable and make intelligent decisions then contact us and learn how to adapt readily available technology to your project.
