能否从Fulfillment Service中获取已配置的Google Smart Home房间/位置信息？

Great question! I’ve built several Google Smart Home integrations, so I can confirm this is totally possible—here’s how it works:

• You’ll get room context in action.devices.EXECUTE requests
  When a user issues a room-targeted command like "Turn off all devices in my office", Google includes the room/location details directly in the EXECUTE request payload. Look for the context object, which contains a location field with the user-configured room name.

  Here’s a simplified example of what that payload might look like:

  {
    "requestId": "abc123",
    "inputs": [
      {
        "intent": "action.devices.EXECUTE",
        "payload": {
          "commands": [
            {
              "devices": [{"id": "my-office-lamp-01"}],
              "execution": [{"command": "action.devices.commands.OnOff", "params": {"on": false}}]
            }
          ]
        },
        "context": {
          "location": {
            "name": "Office",
            "roomHint": "Office"
          }
        }
      }
    ]
  }
  

  The roomHint field is your go-to here—it’s the exact room name the user set up in their Google Home app.

• SYNC requests don’t include user-assigned rooms (but you can pre-set defaults)
  The action.devices.SYNC intent is only for listing your available devices to Google. While you can add a roomHint attribute to your device objects in the SYNC response to suggest a default room, users can override this in the app. To get the actual room the user chose, always rely on the EXECUTE request context.

• A few quick tips

  • Room names are user-defined, so they might be inconsistent (e.g., "Office", "Home Office", "Work Nook")—build flexible string matching into your fulfillment logic if you need to map rooms to internal systems.
  • If you want to persist room associations for devices, cache the roomHint value from EXECUTE requests linked to each device ID.
