How to get power feedback?

[husa550]

Hi

I have an electrical power meter that is connected to an online service.

If i type this command in to a webbrowser : https://my.eliq.se/api/datanow?accesstoken=783b7e1af70b4b57ac9fa3c014f9xxxx

I get this in the browser window: {"createddate":"2014-01-12T18:08:58","power":9575.0}

"power":9575.0 is the actual power used at that moment.

My question is, how can i get the number after "power" to iViewer and realtime update?

CF.request("https://my.eliq.se/api/datanow?accesstoken=783b7e1af70b4b57ac9fa3c014f9xxxx", function(status, header, body) {
    if (status == 200) {
        var returnedData = JSON.parse(body);
        CF.setJoin("s10", returnedData.power);
    }
});

Add this script to your project, it will set the power value to serial join 10.

You could make the whole script one line and attach it to a button, or create a separate .js file in a text editor and add it to your project like this:

function requestPower() {
    CF.request("https://my.eliq.se/api/datanow?accesstoken=783b7e1af70b4b57ac9fa3c014f9xxxx", function(status, header, body) {
        if (status == 200) {
            var returnedData = JSON.parse(body);
            CF.setJoin("s10", returnedData.power);
        }
    });
}

Then you simply add this script to your button: requestPower();

Hi and Thank's Jarrod!

I made a scriptfile called Power_script.js and put this in it:

function requestPower() {
    CF.request("https://my.eliq.se/api/datanow?accesstoken=783b7e1af70b4b57ac9fa3c014f9xxxx", function(status, header, body) {
        if (status == 200) {
            var returnedData = JSON.parse(body);
            CF.setJoin("s10", returnedData.power);
        }
    });

} 

The xxxx in the end of command is replaced with the correct numbers

Changed serial join to 500, my s10 was already used.

Made a button with this: requestPower();

And finaly i made a textfield with serial join 500

Sorry to say but nothing happends when i push the "Power" button.

You should run the debugger to check for any syntax errors:
http://commandfusion.com/docs/scripting/debug.html

Also, note that the CF.request function will only work if you are using a licensed device. So make sure you have a valid license in your GUI project before uploading it to your device.

Are you sure the "access token" still remain valid after few minutes/hours? It looks like one of these bridge accesses via an online platform, am I right? Can't you access the equipment directly on it's IP address from you network?

Hi and sorry for late reply.

I wrote the first text just before i hade to go to work and did not have time to look at it again untill now.

I have a valid license so that will not be the problem.

I run the debugger and that can't find any syntax error.

The acces token is valid for ever or untill i change it my self.

The only thing that happen in debugger when i push the button is:

Pusched  = d0 = 1

Released = d0 = 0

This is the complete command with the right acces token.

It works if i type it in a browser and reply:

{"createddate":"2014-01-13T21:42:52","power":2835.0}

Feel fre to test :-)

Hi,

You first need to understand where the error actually is...ie. Do you know if the button press is even calling the function you defined?

Let's start from the start.

I assume you have this script in a file in the same folder as the gui (say called main.js) added the script to the gui using Script Manager as per here? http://www.commandfusion.com/wiki2/software/gui-designer/script-manager

If so, add some debugging output to the script using cf.log and cf.logobject to see what is happening (http://www.commandfusion.com/docs/scripting/util.html#cF.log) and post script and debug.

Once you know where the issue is (ie. not calling script at all, error in json response, error in cf.request etc) I suggest you post the full script (eg. main.js) to pastebin and post a link here so we can see it.

cheers.
