如何通过智能家居应用的实时Feed报告设备上的状态更改？

Question

Documentation for SYNC intent mentions that if willReportState property of a device is true , the device will report its state through Real Time Feed.

How do I write state updates to the Real Time Feed? I can't find any documentation on it.

Answer 1

The documentation to do it is available.

First you'll need to enable the HomeGraph API and obtain an API key. Then you should send a POST request to https://homegraph.googleapis.com/v1/devices:reportStateAndNotification with a JWT and the following payload:

{
 "requestId": "ff36a3cc-ec34-11e6-b1a0-64510650abcf",
 "agent_user_id": "1234",
 "payload": {
    "devices": {
      "states": {
        "1458765": {
          "on": true
        },
        "4578964": {
          "on": true,
          "isLocked": true
        }
      }
    }
  }
}
