Azure 適用於 Raspberry Pi 4 的 IoT Central 設備模板

Question

我只是在關注這個文檔，我看到樹莓派 4 沒有設備模板，但是對於像 MXChip 這樣的設備，它有嗎？ 或者有什么方法可以獲取樹莓派 4 的設備模板？

Answer 1

這是有意的。 設備模板描述了設備的功能。 例如，MXChip 將發送溫度、濕度和運動事件（除其他外），這在設備模板中進行了描述。 您還在屏幕截圖中發布的 ReButton 將具有按鈕按下等功能（支持單/雙/三/長單擊）。

這給我們帶來了 Raspberry Pi 沒有模板的原因，該設備本身沒有開箱即用的功能將其連接到 IoT Central。 我可能決定為其添加一個溫度傳感器，因此我將構建一個描述該功能的模板。 但是您可能決定為其添加一個按鈕和一個 LED，因此您將構建一個描述這些功能的模板。

正如您在評論中所說，如果您想要一個起點，您將從最基本且幾乎為空的功能 model 開始，但是您不能沒有任何接口的功能 model，因此您可以添加 Microsoft 提供的 DeviceInformation 接口. 您需要編寫 Raspberry 將運行的代碼來實際填寫這些字段！

我的建議是在 IoT Central 中創建您自己的接口，雖然以上是一個不錯的起點，但在 IoT Central 中創建您自己的接口只需一分鍾，然后您就可以添加自己的接口。

希望這能解釋一下。 如果您需要任何澄清，請告訴我。
