The application depicts a dashboard screen by default with current status and hierarchy level of the devices with information to enable the user to understand which devices are active, in working condition and recently used. The user can thus check the total devices plugged-in, count of devices in active mode and count of devices in inactive mode. The user can also check the count of active devices in working and nonworking condition. In addition to this, device battery status monitoring with count of devices under each mode can also be done to ensure every device is in working order. A current status of devices with information of door open/ close information and open time interval is also available to check which doors were opened along with a timestamp. This can also be exported to excel.
