Abstract: Embodiment herein provides an Infrastructure article (101) and method thereof for synchronizing blinks of infrastructure articles in a mesh network. The method includes detecting an expiry of a sync timer counted by a real time clock (RTC) and determining whether a charge level of a battery (105) of the infrastructure article (101) meets a battery charge threshold. When the charge level of the battery (105) of the infrastructure article (101) meets the battery charge threshold, the method includes establishing a connection with other infrastructure article and/or an infrastructure article server (200) in the mesh network, and sending a time to synchronize blink of the at least one light source (106) to all other infrastructure articles in the mesh network. When the charge level of the battery (105) of the infrastructure article (101) does not meet the battery charge threshold, the method includes resetting the sync timer, and initiating a count of the sync timer.

Abstract: Smart locking devices, systems and methods are provided. A user mobile device can transmit a wireless signal to an electronic locking device. The electronic locking device includes a power sensor to sense the harvested power, and a controller to process the communication component to determine an algorithm to operate the electronic locking device. The mobile device is connected to a network environment where user authentication and encryption data can be generated, stored, and relayed to multiple user mobile devices for wireless key management for authentication.
