智能家居 AOG.将设备状态与 Firestore 字段集成的最佳方式(2021 年) [英] Smarthome AOG. The best way (in 2021) to integrate state of devices with firestore fields

问题描述

我有这个项目:

解决方案

您可能需要在 onExecute 中添加一个中间条件到 根据 Firestore 状态返回错误:

//...for(command.devices 的常量目标){const configRef = firestore.doc(`device-configs/${target.id}`)const targetDoc = 等待 configRef.get()const {garagestate} = targetDoc.data()如果(车库状态 === 假){//车库状态存在且为假//返回错误返回 {请求标识，有效载荷:{状态:'错误'，错误代码:'已经关闭'}}}//...}//...

I have this project: https://github.com/neuberfran/firebasefunction/blob/main/firebase/functions/smart-home/fulfillment.js It works well. But, for example, I want to implement a condition that if I have the garage closed and I said "close garage", the Home assistantt will alert me about it.

As shown in the photo below, I am using an rpi3/iot-device/back-end that controls the garagestate field. I need to know the best way to implement this condition, that is, read the value of the garagestate field and from that, know if I can open the garage or not:

解决方案

You'd probably need to add an intermediary condition in your onExecute to return an error based on the Firestore state:

// ...
for (const target of command.devices) {
    const configRef = firestore.doc(`device-configs/${target.id}`)
    const targetDoc = await configRef.get()
    const {garagestate} = targetDoc.data()
    if (garagestate === false) {
       // garagestate exists and is false
       // return an error
       return {
         requestId,
         payload: {
           status: 'ERROR',
           errorCode: 'alreadyClosed'
         }
       }
    }
    // ...
}
// ...
