ESP32 & PubNub Relay and Switch Control

PubNub has updated its C-Core SDK to support newer IoT chips, including the ESP32S3, enabling the creation of sophisticated IoT projects such as managing a ground source heat water pump. This project demonstrates how PubNub can automate the pump's operation based on time and temperature, with manual override capabilities, using an ESP32 chip. The hardware setup involves a temperature sensor, relay, and manual switch, while the software uses libraries like NTPClient.h and DallasTemperature.h to manage connections and gather data. PubNub facilitates real-time logging and remote control of the pump, offering a robust solution for IoT device management with its real-time messaging capabilities. The enhanced SDK is accessible on GitHub, and PubNub encourages users to explore its potential for various IoT applications.
