Eragy has made a free app available for Control4 home control system users. Users can see the cost per hour, easy-to-understand month-to-date costs and estimates—as well as use the system to turn devices like lights on and off. This app is run on Watts on Now! software, which provides a simple user interface that shows the amount of energy being used on the network.

Of course, there's a paid version of Watts on Now! that can monitor whole-house energy use with the addition of a power sensor. Paid version users also have access to a web portal and their energy histories. They can monitor their energy usage from their TV screen, iPad, Control4 touchscreen or web browser. Smartphone users can access their energy info from the phone’s web browser. Specific apps for smartphones are planned.
