Hotels Hilton's mobile-centric hotel rooms coming in 2018 By Danny King / December 07, 2017 Share 1 -- Hilton next year will roll out its "Connected Room" initiative, enabling guests to control room preferences from their smartphone. Connected Room will be available for Hilton Honors members, "scaling rapidly" across the company's U.S. hotels in 2018, Hilton said. Through the Connected Room feature, guests using Hilton's mobile app will be able to control room temperature, lighting, TV channels and window-covering settings, and customize streaming content to the guestroom TV. Guests will be able to help hotels reduce energy usage by synching room-temperature controls with their schedules so that air conditioning or heating are only deployed when the guest is in the room.The app already lets guests do mobile check-in, choose their rooms and open guestroom locks with their smartphone.Hilton said it will expand Connected Room to allow for voice-activated controls for some room settings. It also plans to enable guests to personalize guestroom artwork by letting them download graphics or pictures into in-room displays.
