This module provides interfaces for users to check the energy/power consumption, accumulated energy consumption and the on/off state of a socket, and accumulative energy consumed by a house. User can also check the energy consumption history of a socket via this display module. Besides, when receiving user’s commands, which may be energy limit, peak-time settings, a socket’s priority, AC/UC mode switching, etc., this module sends a data request or control signal to the corresponding control module or stores data into the Memory. For example, if user sets the energy limit via user command processing module, then the value will be sent to ELC module to control the total energy consumption of smart sockets.
