如果安装出现bad install错误。

先运行
sudo apt-get remove nodejs
删除/usr/bin/node文件夹
sudo rm -rf /usr/bin/node

Node-RED在开机时启动。

sudo systemctl enable nodered
sudo systemctl start nodered

检查Node-RED服务的状态。

sudo systemctl status nodered

然后通过HACS添加Node-Red Companion插件
在Configuration.yaml添加如下字符

panel_iframe:
 nodered:
   title: 'Node-Red'
   icon: 'mdi:shuffle-variant'
   url: 'http://192.168.***.***:1880/'

在homeassistant界面创建产期令牌
并且在node-red界面加入IP端口信息'http://192.168..:1880/'，以及令牌代码，全部部署即完成。
