[英]How to handle IDENTIFY request in Google Smart Home Local Fulfilment for multi channel device?
我正在嘗試在我的 Google 智能家居操作中實施本地履行。 我的一些設備有 2 個通道(雙繼電器開關)。
雙通道設備在 Google Home 應用程序中顯示為兩個獨立的設備( light-test123123_0
和light-test123123_1
),它工作得很好。
我已將customData
和otherDevicesIds
添加到我的 SYNC 響應中以啟用本地實現並使用@google/local-home-sdk
構建本地應用程序。 Google Home 識別單通道設備並在本地發送命令。
SYNC 響應正文示例:
{
"response": {
"payload": {
"devices": [
{
"traits": [
"action.devices.traits.OnOff",
"action.devices.traits.Brightness"
],
"customData": {
"path": "/local-fulfil/0/",
"port": 3000
},
"name": {
"name": "light",
"nicknames": [
"light"
],
"defaultNames": [
"light"
]
},
"id": "light-test123123_0",
"type": "action.devices.types.LIGHT",
"deviceInfo": {
"hwVersion": "LIGHT",
"model": "LIGHT",
"swVersion": "1.0",
"manufacturer": "MANUFATURER"
},
"attributes": {},
"willReportState": false,
"otherDeviceIds": [
{
"deviceId": "light-test123123_0"
},
{
"deviceId": "light-test123123"
}
]
},
{
"name": {
"nicknames": [
"light"
],
"defaultNames": [
"light"
],
"name": "light"
},
"deviceInfo": {
"swVersion": "1.0",
"hwVersion": "LIGHT",
"manufacturer": "MANUFATURER",
"model": "LIGHT"
},
"attributes": {},
"otherDeviceIds": [
{
"deviceId": "light-test123123_1"
},
{
"deviceId": "light-test123123"
}
],
"willReportState": false,
"traits": [
"action.devices.traits.OnOff",
"action.devices.traits.Brightness"
],
"id": "light-test123123_1",
"customData": {
"port": 3000,
"path": "/local-fulfil/1/"
},
"type": "action.devices.types.LIGHT"
}
],
"agentUserId": "RuRHIPWpD5W23iGiU81A5PoTKqB2"
},
"requestId": "16772679358918515269"
}
}
當我啟動本地 SDK 實現時出現問題,因為即使我的雙通道設備發送 2 個單獨的 UDP 數據包,具有上述不同的 ID。 谷歌忽略了其中之一。 看起來不可能有 2 個具有相同 IP 地址的設備。
這是 IDENTIFY 請求正文:
{
"requestId": "88DB84992F074FF0B408D8383CF198C4",
"inputs": [
{
"intent": "action.devices.IDENTIFY",
"payload": {
"device": {
"udpScanData": {
"data": "6C696768742D6475616C2D3132335F30"
}
},
"structureData": {}
}
}
],
"devices": [
{
"id": "light-dual-123_0",
"customData": {
"path": "/local-fulfil/0/",
"port": 3000
}
},
{
"id": "light-dual-123_1",
"customData": {
"path": "/local-fulfil/1/",
"port": 3000
}
}
]
}
和回應:
{
"intent": "action.devices.IDENTIFY",
"requestId": "88DB84992F074FF0B408D8383CF198C4",
"payload": {
"device": {
"id": "",
"verificationId": "light-test123123_0"
}
}
}
我編寫了一個發送 UDP 廣播的基本應用程序,它輸出下一個數據:
sent broadcast packet
192.168.1.235:8888 sent this: light-test123123_0
192.168.1.235:8888 sent this: light-test123123_1
這顯示了我的設備在接收到廣播數據包時的行為。
有沒有辦法來解決這個問題?
當前的本地履行平台(從本地主頁 SDK 1.4 開始)通過設備的網絡地址唯一地識別設備,因此它無法處理來自同一物理連接設備的多個廣播響應。
但是,您可以讓一個設備充當多個終端設備的代理,這是通過以下方式完成的:
IDENTIFY
響應中返回將isProxy
標志設置為 true: https://developers.google.com/assistant/smarthome/develop/local#hub-identifyREACHABLE_DEVICES
意圖以返回所有終端設備verificationId
ID:https://developers.google.com/assistant/smarthome/develop/local#hub-identifyLocal Home SDK 示例包括一個可以在此配置中運行的虛擬設備: https://github.com/actions-on-google/smart-home-local#set-up-the-virtual-device
