pi安装homeassistant
HACS

安装完了不是立马可以进入，而是要等系统安装一系列依赖等，还有就是addon可能也不会很快出来，最好保证网络通畅，让其更新.

supervisor添加第三方Home Assistant Community Add-ons

教程官网
在gitee上面创建一个同步仓库URL为https://github.com/hassio-addons/repository
然后

然后添加自己同步的gitee链接即可

Home Assistant Add-on: Terminal & SSH

安装完后，配置

authorized_keys: ["这里是你的公钥"]
apks: []
password: '这里是你的密码'
server:
  tcp_forwarding: false

网络要设置一个端口才可以访问
如果没有设置密码PasswordAuthentication会设置为no,那么你就不能够使用密码验证登录会报错
ssh No supported authentication methods available (server sent:publickey,keyboard-interactive)

ESPHOME

在插入nodemcu后重新进入一下界面即可显示

使用树莓派自带摄像头

usermod -a -G video hass将用户加入摄像头的使用组中，然后重启
Raspberry Pi Camera

安装hacs

github链接
在上述链接下载最新的hacs.zip
然后在Homeassistant的根目录新建custom_components和www两个文件夹，再在custom_components文件夹中新建hacs文件夹，将下载的hacs.zip解压到hacs文件夹中，然后重启homeassistant，然后在集成中搜索hacs安装
然后

打开这个网址，将其中的key填入重启即可
