Has anyone tried using a non-tivo branded bluetooth dongle with the Lux or Vox remote? Just curious if its a standard bluetooth dongle with their logo on it or if it has some specific extra function or just proprietary drivers the tivo uses so only its dongle works. Reason I ask: Tivo sold me a LUX saying it was compatible with my Roamio, but it will not pair. After days with their tech support I am told it requires a bluetooth dongle to work so I have to pay them $10 more. Bad enough, but then I find out they want $13 to ship it standard. Feeling a bit bait and switched and would rather send it back than give them the money, but I really need a new remote.
