After 6 days, It works perfectly. Thanks you guys !

To summarize you have to :

Change line 56 from this.scheduleUpdate(this.config.initialLoadDelay);

to

this.scheduleUpdate(this.config.updateInterval) Change line 169 from setTimeout(function() {

to

setInterval(function() { Optionnal, you can adjust timers at lines 13, 14 and 19

Have fun :-)
