Google-owned Nest is letting its Products get Cozy with other Devices and apps like health trackers, home appliances, and cars. Mercedes-Benz, through its DriveStyle app onboard, can now tell Nest when the driver will likely arrive home, so the thermostat can start heating or cooling at the right time. Jawbone’s Up 24 band can now also do the same, by starting the process before the wearer even gets out of bed. The integrations come courtesy of Nest’s long-awaited API (application programming interface), launched Monday night. It’s a set of commands that allow third-party developers to interface their apps, devices and appliances with Nest’s thermostats and smoke detectors that “learn” their users’ habits. The API is part of Nest’s ambitious push to grow the larger ecosystem of connected devices and software. Integration with Google apps, for instance, is coming in the fall, so people can say, “OK Google, set Nest to 75 degrees,” Nest said. Nest’s goal is to turn the concept of a connected home into a reality, by letting any number of devices or apps integrate with its technology. Through the API, Nest envisions a range of scenarios in which software and hardware developers could build products that interact with Nest’s products and also make use of energy use data.
