HomeAssistant和Node-Red結(jié)合教程

說下背景：
node-red做自動化，協(xié)議解析，采集，轉(zhuǎn)發(fā)，函數(shù)，都是很好用的。因為它有著非常豐富的第三控件。但是奈何dashboard太丑了，沒法滿足要求。另一方面Hass的lovelace就很驚艷，還有著非常豐富的UI組件，權(quán)限控制。兩者結(jié)合下就非常好了，就像前后端分離。
前期準(zhǔn)備：
1.linux基本操作
2.docker
開始搞事
第一部分 node-red
1.node red 安裝：

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

注釋1：1880 就是你訪問 node-red頁面的端口
注釋2：為啥要多 -p 出來個10502呢？因為我是想用node-red做個modbus server的轉(zhuǎn)發(fā)*
2.關(guān)于node-red的一些注意事項：

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

在這里我寫了一點
3.node-red的使用
注釋1：
基本控件的使用，dashboard ，S7，modbus等等的看教程
注釋2：
S7的使用 注意兩點，
一是 西門子200，200smart這類型號的配置，紅框里的要注意，必須是這樣

二是 V區(qū)的變量配置： V區(qū) V直接換成X ，如果是V VD這種去掉V

**注釋3：**modbus
我貼個代碼吧，可以導(dǎo)入看看

4.node-red使用 Hass
暫時省略，不過需要注意的是，只是node-red單獨導(dǎo)入node-red-contrib-home-assistant-websocket 并且配置了hass 也是沒法使用的，必須在hass里面也安裝node-red的插件才可以
5.node-red使用郵箱
暫時省略
第二部分 HASS
1.HASS安裝

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

端口號 8123 啟動
2.下載HACS 壓縮包
HACS可以簡單理解 就是HASS的應(yīng)用商店，可以在這邊安裝node-red的插件，想到哪說到哪吧，就是在這邊安裝也不現(xiàn)實 ，因為是翻墻去github下載，基本不可能安裝成功，所以我是自己電腦掛VPN，下載好文件后，放在custom_components文件夾里，(custom_components一般是沒有的,需要手動創(chuàng)建，創(chuàng)建的位置就是你 掛在出來的文件夾里 例：/opt/homeassistant/custom_components/),要自己下載文件但是怎么知道插件地址呢？這時候你可以在HACS中搜索

紅框點擊 就可以去到該插件的 github主頁了，要哪些文件，放在哪，怎么用github上寫的都比較清楚

弄好之后，重啟docker，在配置–集成里就可以搜索到并且添加進(jìn)來，之后你在node-red里面通過 entity控件添加的實體 都可以顯示出來
entity控件：這里有3個 一個是開關(guān)控制node-red輸出 兩個node-red輸入到hass

hass能顯示出3個實體

最后就可以配置lovelace就可以了

點開關(guān)可以 看到在node-red 控制臺里的輸出
最后 更高深的在研究吧

總結(jié)
