为了给我妈在洗衣服的时候，用洗衣房边上的小米网关听听广播，开发的…
NodeRed里先安装
node-red-contrib-mi-miio
**首先:
**1.米家APP上获取小米网关的token；
2.米家APP上须先收藏要听的广播台；
3.NR里配置：填网关的ip和token；
**使用方法：
**1.第一个func里修改vlaue数值调整音量；
2.第4、5个func是我收藏的中央音乐和央广财经，通过修改id和对应的频道url来换台（其实id改不改没啥用，就是格式罢了）。 url是喜马拉雅电台网络直播的广播地址，我实在记不得哪里可以搜到广播台地址列表了,只能自己找。
3.最后三个是给网关上传、删除和播放自定义音频；
- 上传音频的func里value 分别对应编号和音频地址，编号从10001起步，音频地址必须外网地址，格式是m3u8；
- 播放音频的func里value对应音频编号和音量；
- 理论上可以把tts音频文件转格式后挂外网，上传到网关，实现网关tts，但据说设备内存有限，不建议这样使用。
最后上马：
