Its enough for me too. But not everyone has the same use case and environment. I definitely see why someone would want this.

What I disagree with is that it needs to communicate to the internet to do this. It adds delay and potential for outage if your internet is out. But they do this so they can force you to get their app and milk you for extra data to sell. Internet capable smart devices are to harvest data not grant features. Features could be done better by ZigBee and a hub, but that doesnt grant the device a way to phone home
