I seem to find differently looking hardware versions for the Sonoff RF Bridge (pictures below + look at Itead, AliExpress, Banggood,...). What is the difference between them? Is the difference only esthetical, of is there also a functionality difference ?
If functionality is different, where can we find a comparison? Itead website seems to show only the 2nd picture. But e.g. Banggood website shows customer pictures of the first picture.
Nobody knows the answer ?
