The interface between your appliances and your smartphone continues apace with the Aros smart air conditioner ($300). The air conditioner itself is pretty much what you’d expect: fits in a window, retractable wings, three cooling settings, three fans. Here’s the neat part: not only can you control it with your smartphone, you can use your phone to set a monthly budget, patterning your cooling around how much money you want to spend. Turn it off when you leave for work, schedule it to turn on thirty minutes before you get back—or change the schedule when you decide to hit the bar with friends for post-work brews. Also, it’ll start learning your patterns, making scheduling easier.
