Getting your connected-home gear to actually connect with one another can be a pain. Nest is trying to alleviate at least some of that hassle by adding Weave, its ad-hoc networking system to Works with Nest, it's third party development platform. Weave lets items talk to each other without relying on a home network. The company is also introducing APIs for the Nest Cam with basic camera controls and access to motion and sound events. Plus, it launched a Works with Nest store with hardware that, well, work with Nest. Finally, it showed off a new lock from Yale that works with the fancy new features it just announced.
