复制代码

导入之后做如下动作：
修改“设置提示词Prompt”节点

修改其中的地址为你的家庭住址，越精确越好，人员为msg.payload.open_person，你可以根据你的输入调整。

设置AI大模型的请求参数

    需要改动三个地方（示例的是Qwen大模型）：    模型名称、API 密钥、API地址，这部分需要查对应的大模型文档。

修改输出的小爱音箱实体ID（从MiAuto插件获取）

接入门锁（这部分比较难，大家耐心观看）

这边需要注意的是，触发实体是events:state，大家先配置实体为你的门锁，修改Entity

部署一下，最后触发开门看下你的输出的debug日志试下。

右边的调试窗口输出的是：

2025/10/13 14:50:13节点: debug 31
input_text.lock_record01 : msg.payload : string[3]
"周杰伦"

复制代码

表示的是msg.payload输出的是文本，内容是“周杰伦”。
然后我们看下设置提示词Prompt的代码。

其中原先的第三行代码如下：

<font color="#000000">const person = msg.payload.open_person;</font>

复制代码

然后可以看到调试窗口中的大模型输出结果节点：

"周杰伦开门回家啦！
微风不燥，阳光正好，像极了你回家的路。
欢迎回家，让音乐与爱一起，把日子谱成温暖的歌。"

复制代码

假设上面右边的调试窗口输出的是：

2025/10/13 14:34:13节点: debug 31
input_text.lock_record01 : msg.payload : Object
{"name":"雷军"}

复制代码

就改为如下代码：

const person = msg.payload.name;

复制代码

反正因地制宜，大家把自己的实体输出到调试窗口，如果不知道如何设置，可以留言，我会一一解答。


AI调优
输出的文本部分如果不满意的，可以把输入的提示词到对应的大模型上多次调试，然后按照格式组装到“设置提示词Prompt”节点上。
`我家在${address},结合当地的天气，得出当前${person}开门回家的原因，写一段非常温馨俏皮的欢迎词，不要输出地址信息，字数限制在60到90字之间`根据变量调整一下，最后格式化后填入prompt。

拓展思路：不止欢迎词，还有更多玩法

掌握了“NodeRED+小米Miot+AI”的组合，你还能解锁更多智能家居新姿势：

• 离家提醒：门锁关闭后，小爱播报“记得带钥匙、关灯、关空调哦”。
• 访客播报：当门锁检测到密码开锁（非家人），小爱说“有客人来啦，快去开门～”。
• 节日专属问候：在AI提示词中加入节日信息，比如春节时播报“新春快乐，欢迎回家吃年夜饭！”
