目的：Homeassistant 的Node-red插件之小爱同学语音功能开通，实现播报任意带变量的文本
视频部分效果可见：https://www.bilibili.com/video/BV1id4y1r78d
【Homeassistant 的Node-red插件之小爱同学语音功能开通】
1. 实验环境：
首先需要你安装Node-red插件和小米MIoT设备，我自己根据esp8266采用esphome开发了对应设备，下面列举了部分传感器和执行器
部分传感器显示
执行器显示
我把对应设备进行分区域管理，小爱音箱接入正常
摄像头也接入进来了
安装对于插件亲参照
【小米MIoT设备接入HomeAssistant通用插件教程】
智能家居home assistant之常用插件
ESPHome
2. 实验过程
配置过程：在流程中绘制正确的逻辑控制节点流，部署验证
2.1 打开Node-red
首先说明一下node-red中心思想:条件触发+信号处理+展示动作
2.2 安装node-red-contrib-xiaoai-tts节点
点击右上角菜单按钮
选择节点管理，然后控制板安装搜索node-red-contrib-xiaoai-tts节点
双击流程1编辑其中的内容
我们来命名小爱同学
2.3 添加控制节点流
点击共通的Inject触发器，拖拽到控制流面板中
修改名称为触发器，然后点击完成，单个节点完成对应配置。
在小米菜单中选择音量设置（这一个节点可以省略），接在触发器后面
双击编辑内容
根据提示去ioBroker注册,
然后填写账号密码
呼叫设备
正常联通，会触发小爱语音，小爱设备设置如下，Domain选择xiaoai_miot,智能语音以及合适的设备实体，如果Data不会填可以直接Load案列，我配置的json如下
{"text":"你好鸭！欢迎来到智慧实验室，我是小助手"}
添加调试提示，最后完成小爱节点的配置
不正常联通，则会触发QQ邮箱故障提示，Data配置json如下
{
"message":"<b>当前智慧实验室小助手失效，请重新检测设备</b>",
"title":"消息来自HomeAssistant",
"email":"3126171871@qq.com"
}
添加调试提示，最后完成QQ邮箱节点的配置
为了方便调试选择debug调试
默认配置就好
将他们以此首尾连接，部署所有控制流
我的控制流完整json如下

大家可以直接导入到自己的控制中
2.4 验证结果
点击触发器，正常连接小爱音箱会自动播报，并答应输出
失败就会收到邮件提示
3. 分享带变量的语音播报
3.1 自动播报温度
json配置如下，修改对应报错和设备就可实现
