There are three types of energy consumption managers: 1. Consumption managers that measure consumption in real-time and show it on a display on the wall or on the table. 2. Consumption managers that measure consumption in real-time and show this via an app on your phone. 3. Consumption managers that measure energy consumption and show it a day later via an app or website. The HomeWizard Energy Display falls under the first type (our P1 Meter falls under the second). In addition, there are also differences in the size of the display, the costs and how user-friendly the display of an energy consumption manager is.
