ESPHome: Flash the config to the ESP

Introduction

The ESP board is a small mini computer with onboard Wifi. ESPHome makes it easy to program these boards.

You define for each ESP board the connected sensors in a template. In the template, you define your ESP board and which and how the sensors are connected. The sensor also automatically registers itself to Home Assistant (or sends its data to a MQTT server).
