The hardware made a solid impression at first, so I took the test after receiving the small starter set. So app downloaded and launched. Then I had to create an account ... walked past it, no way. Even if one wants to use the controller only locally - ie not through the cloud. After signing up could then but still not ready to go, because Gateway, App and lamps only once needed an update ... But now to the test: and equal to the first confrontation with the GUI ... Somehow the lamp did not know what the App promised. Time delayed sometimes not. As I opened the help within the app, and lo and behold, in a unique mix of German, English and French things were explained to me that I -To get this far - had already circumnavigated successfully. App was nothing there. It really is only the means for App ... Without words. So should be the first app, for which I have downloaded a manual to ensure that it is not the classic Layer 8 problem (User too stupid for software) is here this fact. Ultimately confirm this but only that the software is not intuitive, and further still, the whole interaction poor to work even worse. Alpha testing on customers. Ugh ...
