Savant has been selling an iPhone app called Rosie since last September that allows users to command just about all things electronic in the house: lighting, security, and home entertainment. By combining a hardware hub at home with a monitoring server, subscribers can remotely control many functions, like security (cameras), climate (A/C and furnace), and entertainment (TV and stereo). While that’s a little swanky for a private residence, I could see lots of solid commercial applications for something as unified and mobile as Rosie. Savant’s app is a little priey at $49.99, and you need to have the local hardware set up as well, but Canadians can get downloading in the iTunes App Store over here, or check out a video demo here.
