Node-Red Dashboard
Node-Red Dashboard 是提供Node-Red 流程资料展示的一个中方式.Dashboard 提供丰富多样的人机界面组件,适用于展示设备的监测数据.
安装
在节点管理 界面找到 node-red-dashboard 安装即可.如下图:
找到 {user}/.node-red/settings.json 去掉 ui: { path: "ui" } 前面的注释.
访问 http://ip:1880/ui/ 出现以下界面则安装完成.
配置dashboard
把node-red选项卡切换至dashboard配置界面,如下图:
- Layout 用来管理
dashboard的布局
- Site 是网站的一些设置
- Theme 是网站样式调整
如果没有添加控件在dashboard 中则会显示空白,点击tab 点击一个新栏目,然后下面可以添加group, group里面添加组件.动手尝试一下即可以发现互相的关系.
每日油价练习
node-red启动或每天早上六点从 油价网获取指定地区的油价,如需修改则修改油价网里面对应链接即可.
