The user interface on this app is garbage. Why, after physically turning off a light with the switch, do you have to REINSTALL the device EVERY TIME once you turn the switch back on?! Otherwise it just flashes. Other settings/options are difficult to decipher/navigate to as well. Power goes out, all lights go on. I've had a light that I haven't been able to reinstall for months that is obviously controlled by this app because it's dim, but can't control it. Not impressed.
