So I can see with the BT TV Pro Box that its remote is bluetooth, I use HDMI over ethernet with IR Passback round the house so I can watch tv in what ever room i'm in. Is there an option to add additional remotes? For example with my current Sky Q setup the main remote in the living room is setup as a Bluetooth remote but I have several other remotes around the house that are IR. It was faff but you basically paired the remote to setup the TV options then held certain buttons and then they turned off bluetooth and reverted to IR. Does the BT TV Pro offer this?
You can't have more than one BT remote but the box also simultaneously responds to the Humax IR of the older boxes. So buying those should work for you, plenty on Ebay.
