Nest to build out IoT with acquisition of Revolv's home hub engineering team

The next step for IoT in the home will enable devices from different manufacturers to communicate with each other.

Spending $3.2 billion for Nest in January, followed by a $555 million buyout of Dropcam in June and last week's acquisition of Revlov for an undisclosed amount, Google is moving quickly into the home Internet of Things (IoT) market.
