【Homeassistant 的Node-red插件之小爱同学语音功能开通】

• 1. 实验环境：
• 2. 实验过程
• • 2.1 打开Node-red
  • 2.2 安装`node-red-contrib-xiaoai-tts`节点
  • 2.3 添加控制节点流
  • 2.4 验证结果
• 3. 分享带变量的语音播报
• • 3.1 自动播报温度
  • 3.2 播报当前时间
  • 3.3 播报多个变量文本

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

1. 部分传感器显示
   

2. 执行器显示

3. 我把对应设备进行分区域管理，小爱音箱接入正常
   

4. 摄像头也接入进来了

安装对于插件亲参照

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":"当前智慧实验室小助手失效，请重新检测设备","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
