Desarrollo e implementación de un sistema domótico de líneas eléctricas para sucursales de Unidrogas S.A.S.

Abstract

Unidrogas S.A.S. is a Colombian company dedicated to the nationwide distribution of pharmaceuticals. In its branches, the manual control of electrical lines led to operational inefficiencies due to human error, resulting in unnecessary energy consumption. To address this issue, a home automation system based on an ESP32 was developed and implemented, enabling the automated switching of low-power electrical lines using contactors via an HTTP connection. The system integrates a centralized database and Python scripts to manage and execute scheduled operating times. Load and stress tests were conducted by subjecting the system to periodic activations over several days without interruption, validating its stability and accuracy. Additionally, a physical structure was designed to ensure proper ventilation, thermal dissipation, and ease of maintenance. As a result, efficient management of electrical lines was achieved, reducing manual intervention and optimizing energy consumption in the branches, leading to a 15% to 22% reduction in electricity consumption in two of the four automated branches.
