米家/小爱同学通过 Home Assistant 控制第三方设备
目标
通过米家或小爱同学控制接入到Home Assistant的第三方设备，实现语音控制或自动化。
实现流程
小爱同学/手动触发 → 中枢网关 → 产生虚拟事件 → Xiaomi Home(Home Assistant) → NodeRed（解析虚拟事件） → 控制设备（如打开空调）
必备条件
- 中枢网关
- 小爱音箱（可选，用于语音控制）
- Home Assistant
- Xiaomi Home 插件
- NodeRed （可选，用于复杂控制流程）
- Midea AC LAN 插件（适用于美的或Colmo设备）
实例：通过小爱同学控制打开Colmo的中央空调
前置条件
- 已经安装【必备条件】中的设备和插件，并且中枢网关、NodeRed、Colmo中央空调已经接入到 Home Assistant。
操作步骤
一、米家 - 产生虚拟事件
- 智能
- 右上角⊕
- 手动控制
- 输入个名称：【打开主卧空调】
- 将设备调整到：
- 添加执行动作
- 家居设备
- 选择 中枢网关
- 产生虚拟事件：【打开主卧空调】
- 保存
- 重新进入刚才创建的【打开主卧空调】
- 右上角 ⋮
- 小爱语音控制
- 在自定义指令中可以添加其他命令，比如【打开主卧中央空调】等
按照以上步骤，可以添加【关闭主卧空调】等操作。
二、NodeRed - 接收和处理虚拟事件
- 新建一个流程，命名为 【中央空调】
- 拖一个 home assistant 分类下的 events: state 到 画布
- Name：中枢网关-虚拟事件发生
- Entity：选择 【中枢网关 虚拟服务 虚拟事件发生】
- If State：is not 后面的文本框留空
- State Type：string
- 输出属性
- data: event data
- payload: 表达式 data.new_state.attributes.事件名称
- 拖一个 功能 下的 switch 节点到画布
- 名称：打开主卧空调
- 属性：payload
- 输入值匹配符号：==
- 匹配值，也就是虚拟事件名称：打开主卧空调
- 鼠标左键按住 中枢网关-虚拟事件发生 右边的连接点，并移动鼠标到 打开主卧空调 对象的左边连接点，完成连接
- 拖一个 home assistant 分类下的 action 到 画布
- Name：打开主卧空调
- Action：climate.turn_on
- Entity：选择 【主卧中央空调】
- 连接两个 打开主卧空调
- 根据以上流程可以添加 关闭主卧空调
- 后续还可以查询空调运行状态，并语音播报
