Requesting feedback at regular intervals and JSON parsing

Hello.

You can use a recursive Settimeout() to execute the function every 200 MS. Use SetIntertval() with this value is not recommended because will surely get a memory leak. You can use the following code to get the pre-known value of an element from JSON:

var tmp = '{ "qwerty": "1234567890" }';

IR.Log(JSON.parse(tmp).qwerty); // 1234567890

Thanks Vladimir

I will try this now!

The bit from the JSON I need is

LEVEL 1 = 0

LEVEL 2 = state

LEVEL 3 = buttonevent: XXXX

HI Vladimir

Focusing on the JSON stuff, I think I may have your syntax a bit wrong. Is this on the right track?

function sendRequests()
{
   // ***request status of Sensor 12 - Buttons - eventually these scripts will need to listen to 10x buttons***
   IR.GetDevice("hue").SendEx({ 
         Type: "GET",                                                                    
         Url:  "/api/a8CaS3oaTHN0mL-1IgKZgYRzXTLL3kIbJVApJukm/sensors/12",      
         cbReceiveText:       function(text),  
            var tmp = '{"state": "buttonevent"}';
            IR.Log("JSON.parse(tmp).buttonevent");
            str.charAt(1);
            }
            
     {
      switch (buttonevent)
            // ***Code to go here to parse response data and extract state > buttonstate > XXXX***
            IR.GetPage("Page 1").GetItem("buttonstate").Text = text;  

Hello.

Example of our project:

JSON.irpz

In your case, the code should be:

var tmp = '{"state": "buttonevent"}';
var result = JSON.Parse(tmp).state;
IR.Log("Result = " + result);

Hi Vladimir - thanks for your awesome support. I tried to insert this code but it either breaks my code, or it still shows the old results. I have attached my project for your reference. Hue Dimmer Button Demo

In the presented project, you send a GET request script and get a string. Give an example of the string you are getting. In the editor you have incorrectly configured sending commands. If you want to access the server via a script, remove the bindings to the buttons. So it will be more clear what is happening.

Now we would like to start with this:

IR.AddListener(IR.EVENT_START, 0, function()
{
IR.GetDevice("hue");
sendRequests();

});

function sendRequests()
{
IR.GetDevice("hue").SendEx({
Type: "GET",
Url: "/api/4pIBQMqs2Nib6JgK9XtBsaACKKClGAUTKrOtjivg/sensors/14",
cbReceiveText: function(text, code, headers)
{
IR.Log("Text: " + text);
IR.Log("Code: " + code);
IR.Log("Headers" + headers);
}
});
}

Somebody find the log output of iRidium.

Please to share that a clever colleague has solved the parsing problem for me. Only thing left is for it to poll the bridge every 100ms for a status change.

IR.AddListener(IR.EVENT_START, 0, function()
   
{
   IR.GetDevice("hue");
   // ***get Hue driver***
   sendRequests();
   // ***send request for API***  
   // ***Code to go here to request status every 100ms regardless of active page or popup***         
});

function sendRequests()
{
   // ***request status of Sensor 14 - Buttons ¬ eventually these scripts will need to listen to 10x buttons***
   IR.GetDevice("hue").SendEx({ 
         Type: "GET",                                                                    
         Url:  "/api/4pIBQMqs2Nib6JgK9XtBsaACKKClGAUTKrOtjivg/sensors/14",      
         cbReceiveText:       function(text)  
         {
            var response = JSON.Parse(text);
            var buttonEvent = response.state["buttonevent"];
            var numberToString = buttonEvent.toString();
            var firstNumber = numberToString.charAt(0);
            // Takes the first number of the button event response which correlates to the button press.
            // This is then parsed allowing the button to trigger something in iRidium unstead.
            switch (firstNumber)
            {
              case '1':
                        IR.GetPage("Page 1").GetItem("buttonstate").Text = "number 1 has been pushed.";    
              break;
              case '2':
                     IR.GetPage("Page 1").GetItem("buttonstate").Text = "number 2 has been pushed.";
              
              break;
              case '3':
                     IR.GetPage("Page 1").GetItem("buttonstate").Text = "number 3 has been pushed.";
              
              break;
              case '4':
                     IR.GetPage("Page 1").GetItem("buttonstate").Text = "number 4 has been pushed.";
                            
              break;
              default:
                            
              break;
            }
              
         },
   
   });
}

// The current response without parsing is as follows. What is important
// is the first number after state > button event > XXXX

// *start of response from API for Sensor = 12*

Hello.

The poll can be done through a recursive IR.SetTimeout. If done through IR.SetInterval, the interval of 100 MS can be critical for the stable operation of the server.

Thank you - this is working beautifully. I inserted:

IR.SetTimeout(200, sendRequests);

However I am now finding it repeating the result every 200ms (display text, play a sound). Next task is to have it query the device and if nothing has changed since last time, do not issue a command. 

Hello.

You can save the last received value to a variable and compare it when you get a new value. If they are not equal, then call some function. See attached example.
