Love the Hatch device itself and would give 5 stars if the app wasn't so awful. I have two devices - one in my daughter's room and one in my newborn son's room. The app routinely refuses to connect to the room I need at that moment, usually the room I am in at the time. So I will work so hard to get my baby down for a nap, go to the app to turn off the light, and, although it has just been connected a moment before, it will show up disconnected and will not reconnect unless I restart.
