Summary I have a Home Assistant installation at home and I wanted to experiment with ESPHome to explore a variety of sensors and switches. The main reason I want to use ESPHome is to control sensors and switches that lack wireless connectivity. Microcontroller boards such as ESP8266 and ESP32 provide WiFi capabilities and a TCP/IP stack simplifying network integration. Additionaly, they offer numerous GPIO pins, I2C and UART interfaces to connect to other devices.
