Extending Range of Comcast X1 Remote XR11

Hi all. I am trying to find a solution to extend the range of a Comcast X1 remote model XR11. My cable box is two floors below the TV. I’d like to be able to use the Comcast remote and its voice search capabibilities, but unfortunately the cable box is too far away.

I have read that the X1 remote uses the ZigBee RF4CE to communicate with the cable box, and the voice search uses voice-over-RF4CE. The chips are from Texas Instruments. Does anyone know of a solution (like a Zigbee repeater or range extender) that I can put halfway between cable box and the TV to facilitate the remote communicating with the cable box? I don’t have any other Zigbee equipment running in the house.


Have you figured this out, ha e same problem, outdoor tv is just about 20’ too far away to control cable box I side house inside a closet.
