Not really - these lights are always on, so if the hub croaks, your lights can still be turned on/off the old-fashioned way. I actually got touch guards installed on all the switches so the guests don't press them - you can still poke it with a pencil and toggle. In almost 10 years, I have never had to do it. The only drawback is that if the power goes in and out - all the lights come on. This is where remote functionality is useful, if you are away.
