智能系统 篇一：#homeassistant# 帮我做个决定吧！拥抱NodeRED之自动随机回答TTS给小爱音箱

在homeassistant中NodeRED是必不可少的工具之一，Node-RED提供了一种可视化的方式来创建自动化流程，而Home Assistant则提供了广泛的智能家居设备支持和自动化功能。结合两者，可以实现更复杂、更灵活的智能家居控制和自动化，在往后的教程中我会提到各类品牌，如米家、涂鸦等利于平台从而得到全屋贯通智能

其中在Home Assistant中使用Node-RED有几个主要优点：

• 可视化编程： Node-RED提供了一个直观的用户界面，让用户可以通过拖拽节点、连接它们来创建自动化流程，而不需要深入编程知识。这使得创建复杂的自动化变得更加容易和直观。

• 丰富的节点库： Node-RED社区开发了大量的节点，涵盖了各种各样的功能和设备。在Home Assistant中，这些节点可以与Home Assistant的实体进行交互，包括传感器、开关、灯光等，从而实现更多样化的自动化场景。

• 灵活性： 通过Node-RED，用户可以更加灵活地定制自己的自动化流程。无论是简单的条件触发还是复杂的逻辑判断，都可以通过Node-RED的节点来实现。

• 与其他服务的集成： 除了与Home Assistant的集成外，Node-RED还可以轻松地集成其他云服务和第三方平台，例如IFTTT、Twitter、Facebook等，从而实现更多样化的自动化场景。

• 实时调试和监控： Node-RED提供了实时的调试和监控功能，可以帮助用户快速定位和解决问题，提高自动化流程的稳定性和可靠性。

  下面图片包含以下几个节点：

  1. Inject 节点 (3bc2f45862550d42)：用于触发流程的启动，你可以在这里配置触发流程的条件或时间。

  2. Function 节点 (2999211792721746)：通过 JavaScript 编写的函数，用于生成随机的洗碗任务，并将其作为消息的 payload 返回。函数内部定义了一个包含了三个任务的数组 tasks，然后根据随机数来选择一个任务，确保了不同的任务被选中的几率相等。

  3. API 调用服务节点 (ccfc6ff3d22fad18)：用于调用 Home Assistant 中的服务，这里是调用 text.set_value 服务来将随机选中的洗碗任务发送到指定的实体 text.xiaomi_l17a_331c_play_text。

  4. Home Assistant 服务器节点 (22e610f8da6c05ed)：用于连接到 Home Assistant 服务器，配置了连接信息和一些选项。
