一、安装ESPHome

uv init
uv add esphome

uv run esphome dashboard ./esphome

二、配置ESP32-C3控制灯

注意事项
1. id和name要用英文，不要用中文
2. wifi连接要用2.4GHz，不要用5GHz
3. i2c要注意frequency的设置

文件目录如下

ESP32-C3开发板

1.主配置文件esp32c3-luat.yaml

# https://wiki.luatos.com/chips/esp32c3/board.html
esphome:
  name: esp32c3-luat
  friendly_name: esp32c3-luat
#  name_add_mac_suffix: true
  platformio_options:

    board_build.mcu: esp32c3

esp32:
  # HARDWARE: ESP32C3 160MHz, 320KB RAM, 4MB Flash
  board: esp32-c3-devkitm-1

2.基础通用配置base.yaml

# https://esphome.io/components/wifi
wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  fast_connect: true

# https://esphome.io/components/ota
ota:
  platform: esphome
  password: !secret ota_password

# https://esphome.io/components/api
api:
  encryption:
    key: !secret api_encryption_key
  # 没有连接HA，默认15min会重启一次，设置为0s，将不再重启
  reboot_timeout: 0s

# https://esphome.io/components/web_server
web_server:
  port: 80

# https://esphome.io/components/mdns
mdns:
  disabled: false


text_sensor:
  # https://esphome.io/components/text_sensor/version
  - platform: version
    name: "Version"
  # https://esphome.io/components/text_sensor/wifi_info
  - platform: wifi_info
    mac_address:
      name: "Mac"
    ip_address:
      name: "IP"
      update_interval: 1min
    dns_address:
      name: "DNS"
      update_interval: 1min
    ssid:
      name: "SSID"
      update_interval: 1min
    bssid:
      name: "BSSID"
      update_interval: 1min

3.密码文件secret.yaml

上面base.yaml中!secret wifi_ssid就是引用secret.yaml里面的wifi_ssid的值

# Your Wi-Fi SSID and password
wifi_ssid: "xxx"
wifi_password: "xxx"

api_encryption_key: "xxx"
ota_password: "xxx"
ap_password: "xxx"

4.围栏灯four_light.yaml

三、安装固件

四、HomeAssistant配置ESPHome

1.直接访问

2.配置ESPHome地址

如果配置了api_encryption_key，需要填写密钥

3.接入成功
