Last time I bug you with that I promise. I fixed it that way case this.config.notifications.VOLUME_DOWN: var vol = parseInt(this.currentVolume) - curUpDownScale if (vol < 0) vol = 0 this.sendSocketNotification(this.config.notifications.VOLUME_SET, vol) break case this.config.notifications.VOLUME_UP: var vol = parseInt(this.currentVolume) + curUpDownScale if (vol > 100) vol = 100 this.sendSocketNotification(this.config.notifications.VOLUME_SET, vol) break By adding the parseInt to make sure that it’s an integer. All working fine now!! Thank again, really like your module!
