我只是在关注这个文档，我看到树莓派 4 没有设备模板，但是对于像 MXChip 这样的设备，它有吗？或者有什么方法可以获取树莓派 4 的设备模板？

这是有意的。设备模板描述了设备的功能。例如，MXChip 将发送温度、湿度和运动事件（除其他外），这在设备模板中进行了描述。您还在屏幕截图中发布的 ReButton 将具有按钮按下等功能（支持单/双/三/长单击）。

这给我们带来了 Raspberry Pi 没有模板的原因，该设备本身没有开箱即用的功能将其连接到 IoT Central。我可能决定为其添加一个温度传感器，因此我将构建一个描述该功能的模板。但是您可能决定为其添加一个按钮和一个 LED，因此您将构建一个描述这些功能的模板。

正如您在评论中所说，如果您想要一个起点，您将从最基本且几乎是空的能力模型开始，但是您不能没有任何接口的能力模型，因此您可以添加微软提供的 DeviceInformation 接口. 您需要编写 Raspberry 将运行的代码来实际填写这些字段！

我的建议是在 IoT Central 中创建您自己的接口，虽然以上是一个不错的起点，但在 IoT Central 中创建您自己的接口只需一分钟，然后您就可以添加自己的接口。

希望这能解释一下！如果您需要任何澄清，请告诉我。
