Just started my first mirror and added the Domoticz module. To get it to work I change the setTimeout to setInterval but I also had to change the call in the start function from this.scheduleUpdate(this.config.initialLoadDelay) to this.scheduleUpdate(this.config.updateInterval). Not doing this I think it will set the timer to fire every 10 ms and that didn’t work for me. It will take some time(this.config.updateInterval) to get the module up the first time but I can live with that until I know js better.
Hope it helps someone.
