About ESPHome
ESPHome turns supported microcontrollers into smart home devices that you control through home automation systems. It is built for devices based on ESP32, ESP8266, BK72xx, and RP2040 chips, and it uses simple configuration files instead of manual firmware editing.
Devices are defined with YAML configuration and updated over the air without physical access. A modular design supports hundreds of sensors, displays, and other components, and devices work locally without a cloud dependency. ESPHome integrates closely with Home Assistant and is a project of the Open Home Foundation.
It is designed for device firmware workflows rather than a hosted service, so the software builds firmware that runs on hardware you provide. Many components can also be run on a desktop computer using the host platform for testing.
