Wrapping all this stuff together is an improved mobile app, which lets you control all your WeMo home-automated devices remotely. New in this edition is the ability to simulate occupancy, Home Alone-style, so that the lights come on at a certain time, making it seem like someone's home. If you're hip to the ways of If This Then That (IFTTT), you can set your lights to go on at sunset each day and turn off at sunrise -- with that time changing as the days get shorter and longer. If you already own some WeMo gear, you'll need to wait for February for the app update to roll out, but it should at least arrive before all those new products Belkin is showing off this week.
