ESP32 Home Automation example (Infrared remote control)

Quick demo of a simple home automation project using ESP32, Secure MQTT (SSL/TLS 1.2), an IR transmitter, an MCP23017 port expander and an HTU21D temperature and humidity sensor. I was intrigued by the built-in rmt (remote control) peripheral of the ESP32. With an infrared transmitter, I'm using it to control my electric fan, air conditioner and TV (only on/off is working).
