Google Assistant SmartHome 入门指南
Google Assistant SmartHome 入门指南
需求
通过Google Assistant 控制一些从设备(Light, Washer等设备), Youtube上一个简短的视频介绍了Google Assistant控制SmartHome的流程。Integrating Smart Home Devices with the Google Assistant
Google Assistant控制第三方从设备，必须通过创建一个Action。
官方文档中Smart Home Washer提供了一个通过Google Assistant控制Washer功能。
在Actions console创建了一个简单的Demo.
1. Create a smart home Action
需要填写项目的名称
选择 Smart Home App
2. Install the Firebase Command Line Interface
Firebase命令行界面（CLI）允许您在本地提供Web应用程序，并将您的Web应用程序部署到Firebase托管。
// 安装firebase-tools
npm -g install firebase-tools
firebase --version
// 如果不是V**网络，会出现授权失败的问题
firebase login
- 成功之后的提示
3. 下载smarthome-washer源码
//源码下载
git clone https://github.com/googlecodelabs/smarthome-washer.git
//
cd washer-start
//
firebase use --add
//
npm --prefix functions/ install
// 部署
firebase deploy --only functions:smarthome
//部署成功之后会提示
✔ Deploy complete!
Please note that it can take up to 30 seconds for your updated functions to propagate.
Project Console: https://console.firebase.google.com/project/supple-tracker-237900/overview
4. Configure your project in the Actions on Google console
https://us-central1-<project-id>.cloudfunctions.net/smarthome
其中<project-id>就是 supple-tracker-237900
- 链接账户
- 配置相关信息
Client ID | Client secret | Authorization URL | Token URL |
|---|---|---|---|
ABC123 | DEF456 | https://us-central1-.cloudfunctions.net/fakeauth | https://us-central1-.cloudfunctions.net/faketoken |
5. Link to the Google Assistant
- 找到 Google Assistant > Settings > Home Control
- 会发现带有 [test] 前缀的 test app
6. Creating a washer
修改 washer-start/functions/index.js中的代码
app.onSync(body => {
return {
requestId: body.requestId,
payload: {
agentUserId: '123',
devices: [{
id: 'washer',
type: 'action.devices.types.WASHER',
traits: [
'action.devices.traits.OnOff',
'action.devices.traits.StartStop',
'action.devices.traits.RunCycle'
],
name: {
defaultNames: ['My Washer'],
name: 'Washer',
nicknames: ['Washer']
},
deviceInfo: {
manufacturer: 'Acme Co',
model: 'acme-washer',
hwVersion: '1.0',
swVersion: '1.0.1'
},
attributes: {
pausable: true
}
}]
}
};
});
- 重新进行部署
firebase deploy
- 重新关联到Google Assistant
- 可以在 Firebase Database 看到washer的信息
- 如果需要控制washer，需要修改washer-start/functions/index.js中
app.onExecute((body) => {
const {requestId} = body;
const payload = {
commands: [{
ids: [],
status: 'SUCCESS',
states: {
online: true,
},
}],
};
for (const input of body.inputs) {
for (const command of input.payload.commands) {
for (const device of command.devices) {
const deviceId = device.id;
payload.commands[0].ids.push(deviceId);
for (const execution of command.execution) {
const execCommand = execution.command;
const {params} = execution;
switch (execCommand) {
case 'action.devices.commands.OnOff':
firebaseRef.child(deviceId).child('OnOff').update({
on: params.on,
});
payload.commands[0].states.on = params.on;
break;
case 'action.devices.commands.StartStop':
firebaseRef.child(deviceId).child('StartStop').update({
isRunning: params.start,
});
payload.commands[0].states.isRunning = params.start;
break;
case 'action.devices.commands.PauseUnpause':
firebaseRef.child(deviceId).child('StartStop').update({
isPaused: params.pause,
});
payload.commands[0].states.isPaused = params.pause;
break;
}
}
}
}
}
return {
requestId: requestId,
payload: payload,
};
});
- 重新进行部署firebase deploy，然后就可以通过Google Assistant 控制了
"Turn on my washer"
"Pause my washer"
"Stop my washer"
总结
按照文档中的示例，熟悉了通过Google Assistant 控制 washer。
