WeMo is essentially a remote control for appliances that can be operated from your iPhone or iPad (sorry Android users, it isn't available for you yet). You simply purchase a WeMo unit ($50), plug it into your outlet and then plug your appliance into the WeMo. Pretty simple! (Bet you wish you’d thought of that.)
You may not want to spring for a WeMo unit in every outlet, but using this guy on a few key appliances like your coffee maker or that downstairs light you always forget about can be really helpful.
Plus, the WeMo works as long as your iPhone has Wi-Fi, so if you’ve always wanted to play with your lights from four time zones away, now you can.
