    The Internet of Things (IoT) paradigm has given new tools and countless opportunities to promote new Smart City initiatives on a worldwide scale. IoT provides the means to remotely monitor, manage and control devices, and to create new insights and actionable information from real-time data. Energy management is one of the most demanding issues within urban centers, owing to the complexity of the energy systems and their vital role (Calvillo, Sanchez-Miralles, & Villar, 2016). Street lighting is an important community service that can consume as much as 40 percent of a city’s energy budget. Consequently, street lighting has emerged as a leading smart city application. The objective of this thesis is to build a proof-of-concept smart lighting network and control system prototype to be used on the windbreaker walkway of the city of Heraklion. Depending on the wind intensity on the walkway, the color-tunable lights will be used to convey the safety situation to would-be visitors. The proposed solution is designed to utilize Wireless Sensor Networks (WSN) to create a grid of low-cost microcontrollers that will regulate lighting based on environmental input. The whole system is designed using open-source initiatives and offers a web-based management application, making it easy to integrate with existing Municipality web-based infrastructure. The main novelty of our system is the use of open standards, the lowcost integration to the existing lighting infrastructure without the need for modifications and the value-added by the proximity capabilities of the used microcontrollers.
