NodeRed解决跨生态的开关/灯具联动

在我们做全屋智能调试的时候，经常会遇到智能开关控制智能灯的情况。

大家都知道,智能开关控制智能灯,往往需要把智能开关转换为无线开关模式。

同时还需要在对应的生态中设置自动化,这样才能够让智能开关和智能灯同时在线,否则当智能开关处于关闭的状态,智能灯就离线了。

但在这里必须要有一个前提, 智能开关和智能灯都必须要接入同一个生态,

比如米家的开关,自动化就必须要在米家里面写, aqara的开关也需要在aqara home里面配置.

今天我这里有一个典型的例子,开关是aqara的,但灯具的调光调色,只能在homekit里面控制.一旦aqara开关关闭了,智能灯具就离线了.

在我的调试方案中, 需要把他们同时都接入到Home Assistant里面统一管理.

那么怎样做到既可以单独控制灯具,又不能丢掉开关的功能呢?

我的方法是用NodeRed来写一个简单的自动化,即可完美解决.

效果是这样的,当我点击开关,不管是在APP上切换开关,还是直接去点按物理按钮,效果都是一样的.

都可以让智能灯具切换开关状态.

基本的思路是这样的:
1. 必须要保持开关的常通电状态

2. 监控开关的状态,断电后切换灯具的状态.

所以在NodeRed中,增加一个状态监控. 当开关被关闭,触发开关再次打开.开关再次打开的时候,去切换灯具的状态即可.
