This post resonates with me, as I was having trouble with my Christmas Tree lights today due to their app which lets me control light effects. On the one hand, the app and being able to customize the colors and effects adds so much extra pizazz to the light set, but it can also be a big headache sometimes. One of the prior sets of xmas tree lights lasted 30 years; no app just turning a knob to one of a limited set of effects.
