MM_Withings module | Values are not being updated

[Fab2k]

Hey everyone,

this is my first post, so hopefully this is the correct category.

I have an issue with the MM_Withings module from john7002 . Access to the API works fine and I can see the extracted value in the Log.

But unfortunately the table does not get updated accordingly.

I am not a JavaScript expert and am kind of desperate.

I stripped down the original MM_Withings.js to just handle the received weight. I attached the code.

It would be great, if you could check the code and point me in the right direction.

Thanks in advance for your efforts.

  // init method
  start: function() {
    this.α = 0;
    // set interval for reload timer
    this.t = this.config.updateInterval * 60 * 1000 / 360;
    this.weight=0;
    Log.info(this.name + " 1st step of execution.");

    this.updateLoad();
  },

  updateLoad: function() {
    Log.info(this.name + "refresh triggered");
    var that = this;

    return Q.fcall(
      this.load.get_URL.bind(that,'weight'),
      Log.info("URL LOADED"),
      this.renderError.bind(that)
    ).then(
        this.extractweight.bind(that), //weight
	Log.info("WEIGHT EXTRACTED"),
        this.renderError.bind(that)
    ).done(
	this.updateWait.bind(that),
	Log.info("BIND UPDATE WEIGHT")
    );

  },

  updateWait: function() {
    this.α++;
    this.α %= 360;
    var r = (this.α * Math.PI / 180);

    if (r === 0) {
      // refresh data
      this.updateLoad();
    } else {
      // wait further
      setTimeout(this.updateWait.bind(this), this.t);
    }
  },

  load: {
    get_URL: function(data_type) {
      switch(data_type){
        case 'weight':
          base= this.config.api.base;
          base2=this.config.api.measure_weight;
          end=this.config.api.authPayload_weight;
          break;
        default:
          return '';
        }

        return Q($.ajax({
          type: 'POST',
          url: base+base2,
          data: this.config.api.authPayload.format(
              this.config.oauth_consumer_key,
              Array(32+1).join((Math.random().toString(36)+'00000000000000000').slice(2, 18)).slice(0, 32),
              this.config.oauth_signature)+
              this.config.api.authPayload2.format(
              Date.now(),
              this.config.oauth_token,
              this.config.oauth_signature)+
              this.config.api.authPayload3.format(
              this.config.clientID)+end
        }));



      },
  },

  extractweight: function(data) {
    var var2=data;
    var obj = JSON.parse(data);
    Log.info("status=" + obj.status);
    Log.info("time=" +obj.body.measuregrps[0].date);
