The outlet analyzes real-time electricity usage and displays graphs that break down consumption and cost by hour, day, month or year. Alerts will notify you when the on and off rules are in effect and when devices are using a certain level of power. 

Designed to replace your standard in-wall outlet, the Currant Smart Wall Outlet has duplex, tamper-resistant receptacles that can be easily installed in homes or businesses.
