Where on the website does it say how it actually works? Because "the it works" page, well, doesn't. It seems it connects to a phone via bluetooth? But also uses Wifi? How does it actually connect to any devices? Does it even do that? Or is it just a bluetooth remote for your phone, and the phone then does the real work? If I put this thing next to my bed, and I use it to control my lights, and I left my phone downstairs - will it work?
