Do you need to use the app to control devices in cabinets
It looks like you can use blue tooth from your smart phone/ipad etc to control hidden devices but can the remote control also control dvd players and other devices behind closed doors?
Yes. My receiver, cable box, Blu-ray and xbox 360 are inside cabinet doors and all are controlled by the remote. That is the purpose of the hub that is also inside the cabinet. The IR blaster is the only piece located outside the cabinet in front of the TV so the hub can communicate with the TV.
