Items that should logically work in tandem—say, smart lightbulbs and Wi-Fi–enabled window blinds—can't. In the short term, engineers are finding ways around these barriers. Revolv, a home-automation company, sells a hub with seven wireless radios that speak 10 wireless languages. The hub automatically connects to any wireless device on a home's Wi-Fi network, including thermostats, lights, and even garage doors. Smartphone and tablet users can control individual devices or groups of them through the Revolv interface. They can also set up prompts, such as "If I turn on the lights, then reset the thermostat to 71 degrees." People can patch automated systems together themselves too. MakerSwarm, a new authoring tool by Maya Design, is like a roll of duct tape for the Internet of Things; it lets users cue up long chains of commands through multiple devices. For instance, an array of moisture sensors could send a signal to a sprinkler system.
