註冊特質
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
Google 助理必須能夠將查詢與傳送至裝置的指令建立關聯。為使這項作業能順利運作，您必須宣告裝置支援哪些功能。這些功能稱為「特徵」。您可以在裝置型號中宣告這些特徵。
Google 已在許多裝置上建立各種常見的特徵。這些特徵並非只與一種裝置類型綁定，可以視需求使用。
新增 trait
您之前定義了模型，現在改為新增特徵來更新模型。在這種情況下，請新增「開啟/關閉」特徵，控制連接到裝置的 LED 燈。
在 Actions 主控台中開啟專案。
選取左側導覽列的「裝置註冊」分頁標籤。
在清單中點選任一模式即可進行編輯。
按一下「支援的特徵」方塊中的鉛筆圖示，新增特徵。
勾選「開啟」OnOff核取方塊。按一下「儲存」。
請務必儲存模型的變更。再次點選「儲存」。
