Google’s Nest division is shipping a new feature for its Revolv smart-home hub: an expiration date. That’s probably not the kind of update owners of the Revolv Hub expected when Nest bought the Boulder, Colo., firm that makes the $300 gadget back in October 2014. But on May 15, that gadget — which wirelessly controls other devices in your home — will go offline permanently. A note on the Revolv homepage says that the company is refocusing its efforts on helping other devices work with Nest gadgets (such as its eponymous smart thermostat). Unfortunately, company co-founders Tim Enwall and Mike Soucie go on to explain, “That means we can’t allocate resources to Revolv anymore and we have to shut down the service.”
