使用ESPHome烧录固件到ESP32-C3并接入HomeAssistant

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

2.基础通用配置base.yaml

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
