如图所示风扇的空洞是非常大，想装什么就装什么！！！！
风扇用了有一年多了，买回来的时候就想改装了
，太太怀孕了 
，所以～～～
加一个光感，可以在lx为0的状态下关闭风扇。
本来想使用esp8266但共需要用10个GPIO，只能使用esp32。
接线原理：
1、强电区------风扇电机是4线，分别是红（高速），白（中速），蓝（低速），和黑（零线）; 摇头是独立的低 速电机。以上使用一个4路继电器控制。
2、弱电区------原来的1档2档3档和摇头档位，分别连接GPIO用binary_sensor来接入，目得是纯物理的情况下也可以控制风扇。
固件使用esphome 代码如下：

-------目前还需在写二个自动化是当风扇1档2档3档都关闭，摇头自动关闭；在19-01时光感为0,关闭风扇。
他那个貌似有互锁的
