Smart Plug



Faced with limited resources and booming demand, the energy industry seeks greater efficiencies within complex energy management and distribution processes, all while providing the best consumer experience. To achieve better service and smarter, streamlined processes, energy providers require reliable, real-time access to data.


A smart plug controls the energy supply of devices connected to it. Using a ZigBee® interface this device connects to a gateway where you can send commands to turn on/off or see the power consumption of the device connected to it.
