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).
