Belkin is in the midst of creating a smart home ecosystem with its WeMo lineup. It already includes a light switch, switch and plug, motion detector, and baby monitor—all of which you control through an iPhone or Android mobile app. You can program lights and the heater to turn on as soon as you walk through the door. Or make sure your coffee machine turns off after you've left the house. The WeMo line is modular, so you can set it up to do a number of different tasks.
