Griffin’s new smartphone universal remote control uses Bluetooth to send commands to an IR emitter that sits near your home theater system. As a result, the $69.99 Beacon doesn’t require the user to attach any dongles or special transmitters to the phone (something that makes other smartphone remotes a pain in the butt). The IR emitter is battery powered, so it can be placed wherever is most convenient without the need for running a power cable to it. Models are available for both iOS and Android smartphones.
