The ability to create an app that will be used by clients in their day jobs, but also can help them with other things at home! It's been great working through all of our needs together as we've created this platform over time. There have not really any downsides so far - it has exceeded expectations from both sides (clients & developers). We are creating something very useful here which I think people would appreciate if they had similar problems or wanted more control / visibility into what was going on around the house when away.
