[英]How to handle IDENTIFY request in Google Smart Home Local Fulfilment for multi channel device?
我正在尝试在我的 Google 智能家居操作中实施本地履行。 我的一些设备有 2 个通道(双继电器开关)。
双通道设备在 Google Home 应用程序中显示为两个独立的设备( light-test123123_0
和light-test123123_1
),它工作得很好。
我已将customData
和otherDevicesIds
添加到我的 SYNC 响应中以启用本地实现并使用@google/local-home-sdk
构建本地应用程序。 Google Home 识别单通道设备并在本地发送命令。
SYNC 响应正文示例:
{
"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"
}
}
当我启动本地 SDK 实现时出现问题,因为即使我的双通道设备发送 2 个单独的 UDP 数据包,具有上述不同的 ID。 谷歌忽略了其中之一。 看起来不可能有 2 个具有相同 IP 地址的设备。
这是 IDENTIFY 请求正文:
{
"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
}
}
]
}
和回应:
{
"intent": "action.devices.IDENTIFY",
"requestId": "88DB84992F074FF0B408D8383CF198C4",
"payload": {
"device": {
"id": "",
"verificationId": "light-test123123_0"
}
}
}
我编写了一个发送 UDP 广播的基本应用程序,它输出下一个数据:
sent broadcast packet
192.168.1.235:8888 sent this: light-test123123_0
192.168.1.235:8888 sent this: light-test123123_1
这显示了我的设备在接收到广播数据包时的行为。
有没有办法来解决这个问题?
当前的本地履行平台(从本地主页 SDK 1.4 开始)通过设备的网络地址唯一地识别设备,因此它无法处理来自同一物理连接设备的多个广播响应。
但是,您可以让一个设备充当多个终端设备的代理,这是通过以下方式完成的:
IDENTIFY
响应中返回将isProxy
标志设置为 true: https://developers.google.com/assistant/smarthome/develop/local#hub-identifyREACHABLE_DEVICES
意图以返回所有终端设备verificationId
ID:https://developers.google.com/assistant/smarthome/develop/local#hub-identifyLocal Home SDK 示例包括一个可以在此配置中运行的虚拟设备: https://github.com/actions-on-google/smart-home-local#set-up-the-virtual-device
