I got my IWYs until today, and the same course herumprobiert a bit. When you switch the first time the lamp takes about 2-3 seconds until it starts, I suppose because the control Starts Up first time. From the second time you go a bit faster (1-2 seconds). Unfortunately, I fear that sometimes could be quite annoying - let's see ... I know, I know, usually you should turn the only uebers smartphone, but that's not always the reality)
The right app (Android) "Magic LED Color Controller v2" makes no mad modern impression, but reacts quickly and is doing what it should. Right away I no longer think of what I want to do with the lamp ... :)
A few people have also written a remote control - this is not included, it is only the lamps. Not bother me, but short search has ensured ...
