The connected home race is starting to tighten up. After Samsung acquired SmartThings for $200 million earlier this year, Revolv has been acquired by Nest. Terms of the deal were not disclosed. This is the second big purchase for Nest this year, after snapping up Dropcam in June. Like Dropcam, existing Revolv units will be implemented with the Works with Nest initiative. Unlike Dropcam, Revolv will no longer be available for purchase, and is being pulled from circulation in the wake of this deal.
