Is work, and is usable
I just bought a lamp which use this application. And I’m as developer see big potential in this application. I like about is fast connect to lamp, and have interesting options. I think UX and UI can be improved. Personally I want to have option “Sunset”: When you activate it, lamp started from the full brightness 6000K can slowly reduce brightness to the minimum and 3000K and then turn off light. Time can be 30-60 minutes. Is pretty usable for sleeping :)
