流变量的简单应用[魔方控制3组灯]

lidicn

flow变量

1. flow变量可在同一个flow读取/写入,方便不同的流程互相传递数据.

魔方同时控制3组灯

1. 读取flow变量,当变量为on时,关三组灯,否则开三组灯
2. 开灯的时候,将flow变量设置为on,关的时候设置为off

为何需要flow变量

1. 当未通过魔方控制灯的时候,不会干扰到本流程的执行
2. 比如,手动按开关,开关灯

L大，跟帖问一下，node怎么实现trigger.homeassistant.start，把ha启动作为触发条件呢

谢谢分享，

个嘿嘿  研究一下  node red 的列子都要上

没找到单纯只用node-red的办法

用ha自动化触发,然后通过curl命令 访问node-red的http in节点.

能请教下curl和http in的具体写法么，小白不太懂，我的土办法就只会虚拟一个input，通过input状态打通ha和node
