Dear Customer, Is the Xione model SCXI11BEI remote control for the Xfinity box? Please note that Xfinity's remote is an RF remote. X1 does not support RF functionality. Additionally, Xfinity's RF signal is only for communication between the remote and the box and cannot be programmed to learn commands. We recommend downloading the box's specific brand and model from the app to test compatibility. (Xfinity has a very small IR receiver, just to the right of the status light.) Normally we have to paste the head of one of our IR blasters (it is in the original package) onto the IR receiving area of this device.
