This app sucks. Every time I want to adjust the brightness or set a scene it will not connect or locate the device. So then I have to force stop, clear cache, restart phone. Just for it to connect today I have force stopped it, cleared it, restarted my phone three times and it still did not recognize the device!!!!! At this point I'm done with trying to work it from the app. Good thing I kept the manual I'll just work it from the stupid remote (on wall) which is pointless in the first place.
