前言

做智能家居怎么能不会编辑场景呢，一个好用的场景会节省我们很多的时间不再去操作相同的事，很方便的好吧！！！
下面就来教大家如何编写场景。

1. 安装模块 node-red-contrib-knx-ultimate

已经安装的小伙伴就不用安装了，没安装的就去研究之前的文章，有写过怎么安装模块的。

2. 了解KNX Scene Controller节点

3. 使用KNX Scene Controller节点

案例：客厅明亮

由此可见，输出的结果跟我们设置的一样。这个节点我也经常用非常好用，只要设置好一个场景，类似的场景只要修改一下参数就可以了。

案例：客厅柔和

我只花了10s，好吧，很快就写好了场景，改改参数就行。
