Hi @Clelland82, welcome to the Sonos Community!
As other users have stated, some remotes have Infrared (IR) capability but it may not be enabled by default.
If the remote doesn’t have this option, and only works via Bluetooth or Radio Frequency (RF), then there isn’t any way to get it working with the Ray as per our remote requirements, and our solution would be to use another remote.
In this case, it would be best to reach out to Sky to get confirmation and to see if there are any remote/TV settings you could change to make it output IR.
I hope this information helps!
