Low-cost wireless home automation solution using multiple ESP32 SoCs

Abstract

This paper presents a low-cost smart home system where two types on nodes were developed: the wireless sensor node where the analog or digital sensor is augmented by an ESP32 SoC, and the wired sensor nodes, where the high-power analog or digital sensors are enhanced by the addition of similar ESP32 and an USB or 230VAC power connection. The proposed solution provides features to improve security and quality of life. In addition, we implemented the prediction of the sensor data timeslots which allows energy savings and preventive maintenance (by informing the used when expected communication was skipped)
