Comcast deployed a new device called XR8 which would allow its Xfinity subscribers to control set-tops with “Aim Anywhere” technology that uses the ZigBee RF4CE specification.
This allows up to 5 Xfinity remotes to connect to the XR8 to control the set-top box. Any reason ST could not also sent “remote control” commands to change channels, scroll through the guide, etc.?
Got mine free from Comcast, but also found on Amazon.com: http://www.amazon.com/Xfinity-XR8-Remote-Adapter-Pairing/dp/B00YJTC6KU
