Revolv owners furious as Google shuts down smart home company

Customers furious as Nest is set to turn off Revolv units in just over a month

Google owner Alphabet's subsidiary Nest is closing a smart-home company it bought less than two years ago, leaving customers' devices useless as of May.

In 2014, Google acquired Revolv, the maker of a 210 hub which could be used to control devices such as lights, alarms and doors.
