Rising energy costs are a double whammy for hotels, which are seeing fewer guests during the recession. A ZigBee controller from Control4 lets managers and guests manage the in-room television, video-on-demand, music, smart lighting, temperature and security systems. Hoteliers can reduce energy waste, adjusting lights and HVAC to occupancy. The Suite Controller SC-200's RF signals let guests control TVs and other equipment without line-of-sight issues. The unit also helps attract guests, letting them personalize their entertainment with MP3 and USB inputs, as well as Wi-Fi connectivity. Using a single controller for lights, temperature and TV can also simplify the user experience.
