Nest Cam is Here, But the 'Internet of Things' Still Isn't

Nest, one of the most recognizable names in home automation, unveiled a welcome refresh of its product line here Wednesday. There's slightly smarter software for the thermostat, a slightly thinner, slightly smarter version of the smoke alarm — the $99 Nest Protect — and a slightly thinner, slightly smarter, heavily rebranded version of the Dropcam, now the $199 Nest Cam.
Which is all to the good. But at the same time, the minimal and incremental nature of this Nest event inadvertently displayed the main problem with home automation and the long-promised "Internet of Things." These three products talk to each other well enough — but not much else.
