The Watt app provides real-time insight into your home’s energy usage through the P1 dongle and by connecting your assets. The dongle reads data directly from your smart meter, and your assets can easily be connected through the app, so you can always see how much energy you consume, generate, or feed back to the grid. With the Watt app, you can better understand energy use in your home, use energy more efficiently, and control devices. This gives you better insight into your energy usage and more control over your energy costs. Households with solar panels can also increase the use of their own solar power. The Watt app helps households use energy smarter in a rapidly changing energy system.
