更改Nest恒温器（Nest API）的离开状态 [英] Change Away Status on Nest Thermostat (Nest API)

问题描述

使用 Nest API 我试图设置巢恒温器的状态

• 阅读&
  

• 对于
  恒温器温度控制和设置恒温器，我拥有正确配置的读写权限离开

我可以正确读取状态。有没有人有这个API的经验知道如何去设置这个状态？

在 FirebaseManager.h

  Firebase * newFirebase2 = [self.rootFirebase childByAppendingPath：@结构]; 
 [newFirebase2 observeEventType：FEventTypeChildAdded withBlock：^（FDataSnapshot * snapshot）{
 
 //将结构放入字典
 NSMutableDictionary * dict = snapshot.value; 
 NSLog（@\\\
\\\
\\\
1。Away Status =％@，[dict valueForKey：@away]）; 
 
 NSLog（@Dict Contents％@，dict）; //< ---读取恒温器状态。一个字符串，无论是在家或离开
 
 dict [@away] = @away; //< ---更改状态字符串，但不是一个正确的解决方案，并且不会将stat设置为离开
 
 //更改状态名称，但不会解析回firebase 
 NSLog （@new status =％@，[dict valueForKey：@away]）; 
 
}]; 
  

解决方案

更新子值

$ b

假设这个结构

 结构
 structure_id_0 
 away：home 
  

将离开的节点设置为一个字符串（这段代码相当详细，所以很容易遵循）

  Firebase * structuresRef = [self.rootFirebase childByAppendingPath：@structures]; 
 
 //建立一个引用到我们要写的地方structure / structure_id / 
 Firebase * thisStructureRef = [structuresRef childByAppendingPath：@structure_id_0]; 
 Firebase * awayRef = [thisStructureRef childByAppendingPath：@away]; 
 
 [awayRef setValue：@away]; 
  

现在，如果您想通过使用FEventTypeChildAdded观察节点来获取快照，节点的名称将是什么，而不是structure_id_0。

可以通过snapshot.key获得。

这是key：value对的关键。所以NSString * key = snapshot.key

在路径中替换for @structure_id_0中的键变量。

<请参阅 Firebase书写数据，然后查看updateChildValues为另一种选择。

Using the Nest API I am trying to set the nest thermostat's away status

• Reading & Setting for temperature is working fine.

• I have the read and write permissions correctly configured for both
  thermostat temperature control and for setting thermostat away

I can read the status correctly. Does anyone with some experience of this API know how to go about setting this status?

in "FirebaseManager.h"

 Firebase *newFirebase2 = [self.rootFirebase childByAppendingPath:@"structures"];
    [newFirebase2 observeEventType:FEventTypeChildAdded withBlock:^(FDataSnapshot *snapshot) {

         // Put structures into a dictionary
         NSMutableDictionary *dict = snapshot.value;
         NSLog(@"\n\n\n1. Away Status =  %@", [dict valueForKey:@"away"]);

         NSLog(@"Dict Contents %@", dict); // <--- Reads thermostat status.  A string either home or away

        dict[@"away"] = @"away";  //<--- Changes status string but not a correct solution, and does not set the stat to away

        //Changes status name but this is not parsed back to firebase
        NSLog(@"new status =  %@", [dict valueForKey:@"away"]);

    }];

解决方案

To update a child value

assume this structure

structures
   structure_id_0
      away: "home"

setting the away node to a string of away (this code is quite verbose so it's easy to follow)

Firebase *structuresRef = [self.rootFirebase childByAppendingPath:@"structures"];

//build a reference to where we want to write structures/structure_id/
Firebase *thisStructureRef = [structuresRef childByAppendingPath:@"structure_id_0"];
Firebase *awayRef = [thisStructureRef childByAppendingPath:@"away"];

[awayRef setValue:@"away"];

Now, if you want to do this for snapshots that have been retrieved via observing a node with FEventTypeChildAdded, the node name will be whatever is used in place of structure_id_0. The is the key of the key:value pair.

That can be obtained via snapshot.key.

So NSString *key = snapshot.key

Substitute the key variable in for @"structure_id_0" in the path.

Also check out Firebase Writing Data, and then the updateChildValues for another option.
