How to create and customize your own ESPHome configuration files?

ESPHome configuration files are the core of ESPHome. They define the behavior and functionality of your devices. You can create and customize your own ESPHome configuration files by using YAML syntax and following the ESPHome documentation.

YAML is a human-readable data format that uses indentation and keywords to structure the data. You can use any text editor to write and edit YAML files. You can also use the ESPHome web interface or the command-line tool to create and edit YAML files.

ESPHome documentation is a comprehensive resource that explains how to use ESPHome and its components. You can find the ESPHome documentation on this page. You can also use the search function to find the information you need.

Here are some tips and best practices to create and customize your own ESPHome configuration files:

Use comments: You can use comments to explain and document your configuration files. Comments start with a # symbol and are ignored by ESPHome. For example:

This is a comment

esphome: name: living_room platform: ESP8266 board: nodemcu

Use substitutions: You can use substitutions to define variables and reuse them in your configuration files. Substitutions start and end with a $ symbol and are replaced by ESPHome. For example:

substitutions: device_name: living_room ssid: MyWiFi password: MyPassword

esphome: name: $device_name platform: ESP8266 board: nodemcu

wifi: ssid: $ssid password: $password

Use secrets: You can use secrets to store sensitive information and avoid exposing them in your configuration files. Secrets are stored in a separate file called secrets. yaml and are referenced by using! secret keyword. For example:

secrets.yaml
ssid: MyWiFi password: MyPassword
config.yaml
esphome: name: living_room platform: ESP8266 board: nodemcu

wifi: ssid: !secret ssid password: !secret password

Use includes: You can use includes to split your configuration files into smaller and more manageable files. Includes are referenced by using the! include the keyword and the file name. For example:

config. yaml
esphome: name: living_room platform: ESP8266 board: nodemcu
wifi: !include wifi.yaml sensor: !include sensor.yaml switch: !include a switch.yaml
wifi.yaml
ssid: !secret ssid password: !secret password
sensor.yaml
platform: dht pin: D4 temperature: name: “Living Room Temperature” humidity: name: “Living Room Humidity”
switch. yaml
platform: gpio pin: D1 name: “Living Room Light”

Use packages: You can use packages to group and reuse common configurations across multiple devices

How to integrate ESPHome devices with Home Assistant and other platforms?
