背景
自复位开关->modbus DI模块->node-red->modbus DO模块->继电器->设备（灯具或插座）
参照003篇，已经成功接入两个模块。
思路
在nr里定义一个变量用来记录设备状态，所有的操控都是直接操作这个变量，然后用变量去控制相应的设备。这样，无论控制源是开关、语音助手、传感器、场景、人工智能等都转化为对变量的直接操控。变量可以储存为全局变量或者写入数据库。
var switchCFD = {payload:{power:true,lm:100,colortemperature:100}};
var socketTV = {payload:{power:true}};
var fanNewAir = {payload:{power:true,grade:1}};
然后通过写modbus操作统一改变设备状态。
包括接入的米家设备、mqtt设备等都是通过这个思路来更改状态。
演示
整体流预览
1、初始化，定义全局变量，写入初始状态。
2、获取按键状态、改变全局变量
3、预览
