HomeAssistant和Node-Red结合教程

说下背景：
node-red做自动化，协议解析，采集，转发，函数，都是很好用的。因为它有着非常丰富的第三控件。但是奈何dashboard太丑了，没法满足要求。另一方面Hass的lovelace就很惊艳，还有着非常丰富的UI组件，权限控制。两者结合下就非常好了，就像前后端分离。
前期准备：
1.linux基本操作
2.docker
开始搞事
第一部分 node-red
1.node red 安装：

docker run -d -p 1880:1880 -p 10502:10502 --restart=always -e TZ="Asia/Shanghai" -v myNodeREDdata:/data --name mynodered nodered/node-red

注释1：1880 就是你访问 node-red页面的端口
注释2：为啥要多 -p 出来个10502呢？因为我是想用node-red做个modbus server的转发*
2.关于node-red的一些注意事项：

https://blog.csdn.net/qq_36393991/article/details/115692049

在这里我写了一点
3.node-red的使用
注释1：
基本控件的使用，dashboard ，S7，modbus等等的看教程
注释2：
S7的使用 注意两点，
一是 西门子200，200smart这类型号的配置，红框里的要注意，必须是这样

二是 V区的变量配置： V区 V直接换成X ，如果是V VD这种去掉V

**注释3：**modbus
我贴个代码吧，可以导入看看

4.node-red使用 Hass
暂时省略，不过需要注意的是，只是node-red单独导入node-red-contrib-home-assistant-websocket 并且配置了hass 也是没法使用的，必须在hass里面也安装node-red的插件才可以
5.node-red使用邮箱
暂时省略
第二部分 HASS
1.HASS安装

docker run --init -d  --Restart=always --name="home-assistant" -e "TZ=Asia/Shanghai" -v /opt/homeassistant:/config --net=host homeassistant/home-assistant:latest

端口号 8123 启动
2.下载HACS 压缩包
HACS可以简单理解 就是HASS的应用商店，可以在这边安装node-red的插件，想到哪说到哪吧，就是在这边安装也不现实 ，因为是翻墙去github下载，基本不可能安装成功，所以我是自己电脑挂VPN，下载好文件后，放在custom_components文件夹里，(custom_components一般是没有的,需要手动创建，创建的位置就是你 挂在出来的文件夹里 例：/opt/homeassistant/custom_components/),要自己下载文件但是怎么知道插件地址呢？这时候你可以在HACS中搜索

红框点击 就可以去到该插件的 github主页了，要哪些文件，放在哪，怎么用github上写的都比较清楚

弄好之后，重启docker，在配置–集成里就可以搜索到并且添加进来，之后你在node-red里面通过 entity控件添加的实体 都可以显示出来
entity控件：这里有3个 一个是开关控制node-red输出 两个node-red输入到hass

hass能显示出3个实体

最后就可以配置lovelace就可以了

点开关可以 看到在node-red 控制台里的输出
最后 更高深的在研究吧
