将小米电视通过 Node-RED 接入 HomeKit

创作立场声明：无偿分享，整理自我自己家的HomeKit改造

上一篇文章中我们已经安装了 Node-RED，本文讲如何接入小米电视。

HomeKit

实现功能：关闭电视、方向键、菜单键、返回键、切换常用APP、用 Siri 调整音量

无法实现：回到主页、打开电视

安装节点

通过 IP:1880进入 Node-RED，点击右上角三个横杠，选择“节点管理”。

节点管理

点击“安装”，搜索 redmatic-homekit 节点，安装。

安装节点

绑定MAC与IP

进入路由器后台，绑定电视机的MAC地址和IP，否则IP发生变化会失效，可以参考之前的文章。

点击右上角三个横杠，点击导入，把上面的内容粘贴进去，选择新流程，点击导入，出现以下流程图，导入成功。

导入成功

简单分析一下这个流程图，中间的“小米电视”节点为“核心”节点，也就是一个HomeKit配件，其左边的是传入状态，其右边的是根据用户通过 HomeKit APP 操作后传出的相关指令，不懂也没有关系，可以先去了解一下Node-RED，如果只是为了小米电视的话，跟着我改就行。

修改电视机IP

找到其中两个名为“设定电视 IP”的节点，双击，将IP地址改为你电视机的IP地址，两个节点都这么处理。

修改IP

点击右上角“部署”来保存。

点击红色的“部署”

打开电视机，等它开机后，点击右上角BUG图标进入DEBUG。

DEBUG

点击“查询APP名称”节点前的小方块执行，如果右侧栏DEBUG区域能返回上图msg，则说明连接成功，进入下一步。

查询APP

修改输入源（APP）

HomeKit电视机出了左图的控制器以外，还支持如右图的输入源切换，这个是可以手动设置的，只要滚动选择器，电视机上就能直接打开对应APP，无需通过遥控器找。

HomeKit

获取应用名称

还记得刚才的 DEBUG 信息吗？如下图展开信息，其中的“PackageName”就是应用名称，在这步，记下你需要的所有 APP 的名称。

APP名称

设置 APP 切换

如果你和我一样也是主页（爱奇艺）+腾讯+优酷+投屏，那就不用改了。

双击“小米电视”节点，增删改显示在HomeKit UI上的切换器名称和类型（类型不重要，好像看不出来有啥用），并记住顺序，点击“完成”保存。

增删改

双击“输入源”节点，按照顺序修改名称，一定要一模一样，因为 HomeKit 节点会发一个UI上的名称过来，在这里进行匹配分流到之后的节点，这里的1、2、3、4对应节点后面的四个接口，也可以根据需要添加更多，点击“完成”保存。

注意⚠️：“主页”按钮不建议修改，容易出问题，名字可以改，内容最好不要动。

双击后面的节点，按照之前的顺序，修改名称和APP名称，就是下面的“com.xxx.xxx”，如果节点不够，可以 “Ctrl C”、 “Ctrl V”拷贝粘贴更多节点，用鼠标连接相应的线即可，最后几个 APP 都需要与后面的“切换应用”节点相连。

修改APP名称

完成后点击“部署”

导入HomeKit

双击“小米电视”核心节点，下面会出现一个二维码，用HomeKit扫描即可，会出现关机按钮和切换器。

遥控器的话下拉iPhone的控制中心，最下面会出现 Apple TV 遥控器，如果没有，进入设置、控制中心，添加即可。

遥控器/切换器

代码预设1分钟更新一次状态，也就是说如果使用普通遥控器开启电视，HomeKit会在1分钟更新为开机。
