# 小米智能插座通过米家接入HA然后接入koishi

多此一举的操作（）
不想一步步详细贴出来，毕竟网上都有了，我还写几把（

# HomeAssistant 接入米家app的小米智能插座

# HomeAssistant 部署

可以看看官网，建议使用Docker

HomeAssistant-Docker (opens new window)

docker run -d \
  --name homeassistant \
  --privileged \
  --restart=unless-stopped \
  -e TZ=Beijing \
  -v /opt/homeassistant/comfig:/config \
  -v /run/dbus:/run/dbus:ro \
  --network=host \
  ghcr.io/home-assistant/home-assistant:stable

此处/opt/homeassistant/config是docker映射到宿主机的配置文件路径
浏览器访问http://<host>:8123
创建账号等操作

# HomeAssistant接入米家

1. 在首页左下角（也许），打开设置/配置
1. 然后打开含有集成的配置项
1. 添加集成然后在搜索栏搜索xiaomi,选择xiaomi Miot auto
1. 然后选择Add devices using Mi Account (账号集成)(后面懒得截图了)
1. 填入账号密码, Cloud (云端模式), 别选通过型号/家庭/WiFi筛选设备 (高级模式，新手勿选)
1. 然后账号绑定的设备就显示在首页了

# koishi接入HA

1. 需要在HA创建Token
1. 复制Token，记住这个Token
1. 参考HA的REST API (opens new window)
1. 创建 koishi 插件, 为了更直观的的观测可以做成图表, 因此需要puppeteer
1. 对了，这里说一下怎么获取传感器ID。
1. 这个就是传感器的ID，也就是api里的<entity_id>

koishi插件代码

  // 0:当前功率 1:今日用电 2:本月用电
  const statusArray = ['sensor.cuco_v3_e0d8_electric_power','sensor.cuco_v3_e0d8_power_cost_today','sensor.cuco_v3_e0d8_power_cost_month'];
