I’m kinda despairing with this problem :-(
The idea: requesting the system temperatures of all raspberrys listed in the config file (they are all running a flask server)
But I can’t get the object working.

node_helper gets the object from my config file:

 {
                        module: 'getTemps',
                        header: 'RPi Temperatures',
                        position: 'top_right',
                        config: {
                                 devices: [
                                             {
                                                  url: 'http://10.0.0.83:2222/temp',
                                                  name: 'Alarmpi'
                                             },
                                             {
                                                  url: 'http://10.0.0.25:2222/temp',
                                                  name: 'Mediapi'
                                             },
                                             {
                                                  url: 'http://10.0.0.25:2222/temp',
                                                  name: 'Camerapi'
                                             }
                                ]
                        }
                },

my node_helper.js:

    getJSON: function(object) {
        var self = this;
        var data = object;
        console.log(data);
        for (var key in data) {
                console.log(data[key]);
                request({url: data[key].url, method: 'GET'}, function(error, response, body)
                {
                        if (!error && response.statusCode == 200)
                        {
                                data[key].temp=body;
                                console.log(body);
                                console.log(data);
                        }
                        else
                        {
                                console.log(" Error: " + response.statusCode);
                                data[key].temp = 'offline';
                        }
                });
        }
        console.log(data);
        self.sendSocketNotification('received_values', data);
    }

just one run creates two outputs and the final content of “data” is missing the temperature values.
And as shown in the console output, the received temperature value is always added (it looks like temporary) to the last object in the list.

[ { url: ‘http://10.0.0.83:2222/temp’, name: ‘Alarmpi’ },

51.0
[ { url: ‘http://10.0.0.83:2222/temp’, name: ‘Alarmpi’ },

{ url: ‘http://10.0.0.25:2222/temp’,
name: ‘Camerapi’,
temp: ‘51.0’ } ]
51.5
[ { url: ‘http://10.0.0.83:2222/temp’, name: ‘Alarmpi’ },
{ url: ‘http://10.0.0.25:2222/temp’, name: ‘Mediapi’ },
{ url: ‘http://10.0.0.25:2222/temp’,
name: ‘Camerapi’,
temp: ‘51.5’ } ]
59.1
[ { url: ‘http://10.0.0.83:2222/temp’, name: ‘Alarmpi’ },
{ url: ‘http://10.0.0.25:2222/temp’, name: ‘Mediapi’ },
{ url: ‘http://10.0.0.25:2222/temp’,
name: ‘Camerapi’,
temp: ‘59.1’ } ]

(Mediapi and Camerapi have the same IP in this example)

thanks for your help :-)
