While the app is nice and performs well; it even has extravagant themes and a "Lab". The problem is that it lacks a few basic feature sets you'd expect from any smart light. There is no native sleep timer, and no way to adjust the rate/speed at which the light dims on or off. Lowering the rating because I saw a table lamp for 5USD that had a dimming sleep timer. This is honestly becoming unacceptable that an ecosystem that can run 100's of USD, lacks basic functionality that a $5 lamp has.
