Backed them on Kickstarter – much promised, little delivered.
They were supposed to have a music visualiser built in, be used as an alarm clock, alerts for text messages & social media, remote on/off timer thing for burgalar deterent etc, all sorts of pretty funky stuff really.
All they have delivered so far is on off ability and colour change from same wifi network. And a fairly lacklustre music visualiser.
There are other, better wifi enabled bulbs.
