Was hoping that the little black dot might be luminance sensor, and for that I may have paid extra, but it turns out that it may just be an annoying ‘ambient light’ which I hope is optional, unlink Blink. Time will tell. But as solid as the lights are, I expect an equally solid motion activated Hue bulbs. And if they run locally, which I am pretty sure they will, makes it a very strong competition to Smart Lightning.
